Abstract (sommario):

SummaryThe study assessed adoption of rice post-harvest technologies among smallholder farmers in Osun State, Nigeria. Data were collected from 120 respondents through a structured interview schedule using a multistage sampling procedure. Percentages, means, Chi-square and correlation were used to analyse the data and draw inferences. The results show that about 52.5% of the respondents had favourable perception, while 47.5% had unfavourable perception towards adoption of the rice post-harvest technologies. Rice milling (mean=4.54) and harvesting matured panicles at the right time (mean=4.47) ranked highest among the adopted post-harvest technologies, while majority (65%) of the respondents adopted the rice post-harvest technologies at moderate level and 35% had high level of adoption. Inadequate capital (mean=1.75) and poor extension contacts (mean=1.67) were the major constraints associated with the adoption. Also, there was significant association between sex (χ2= 38.174), marital status (χ2=32.85) and adoption of the rice post-harvest technologies, while age (r=-0.531), household size (r=0.414) and the quantity of rice produced (r=0.345) had significant relationship with adoption of the post-harvest rice technologies. There was moderate level of adoption among the farmers. Financial institutions, governments and non-governmental organisations should provide functional credit facilities and government should employ more extension agents to promote adoption of high-quality enhancing post-harvest technologies for sustainable rice production in Nigeria.

Abstract (sommario):

The study was conducted to determine the perception of food crops farmers on adoption of selected post-harvest technologies in Rivers State, Nigeria. A multistage snow-ball, procedure was used to sample 135 selected food crops farmers in the State. A well, structured questionnaire was used to obtain information from the respondents using both descriptive and inferential statistical tools. The result revealed that, majority (85.9%) of the respondents, were females while 84.4% of the respondents were married. The mean age of the respondent was 41.0 years and highly experienced in food crops production with mean of 15.9 years experience. Majority of the respondents (77%) attended primary school. The level of food crops farmers’ perception on adoption of post-harvest technologies packages was positive, majority (78.1%) of the respondents agreed with the positive statements on adoption of post-harvest technologies, implying the possibility of high level of adoption of post-harvest technologies. The perception of the food crops farmers also had influence on adoption level of the selected post-harvest technologies packages with (P < 0.05). The study concluded that food crops farmers had positive perception of post-harvest technologies in the study area and the study therefore, recommends that Extension should make the technologies available along with training.Int.

Abstract (sommario):

Ninety percent of the world's rice is produced and consumed in Asia. Millions of rice producers are resource-poor farmers with a rice area of less than one hectare. Yield increase and the introduction of double-cropping systems have ensured that rice production has kept up with an increasing demand. However, the increased quantities of grain and the second harvest, which is often in the wet season, have increased the problems in traditional postharvest systems. This can be particularly severe in the humid tropics, where post-harvest losses occur because of outdated management practices and technologies, and delays in post-harvest operations. Fungal infestation of rice grains can lead to discoloration, which results in price reductions in most markets. This can also result in rice being contaminated with mycotoxins, which is less visible to consumers. Contamination with ochratoxins, aflatoxins, and other mycotoxins have occasionally been reported in the literature. In the past, this was not seen as a significant problem and the focus was on other commodities such as maize and peanuts. However, recent studies and a massive recall of food products in Japan in September 2008, including sake, shoshu, and rice crackers made from imported rice from China and Vietnam, which were tested positive for aflatoxins, and also for pesticide residues, have renewed interest in looking at mycotoxin problems in rice. Exploratory studies in the Philippines compared best practice post-harvest management with the traditional management practices often used by smallholder farmers and small processors. It was concluded that synthesis of aflatoxin B1 is very likely in suboptimal post-harvest systems, with levels far above legislative limits. This indicates that there might be a considerable mycotoxin problem in rice from smallholder post-harvest operations. Improved post-harvest management options and technologies are available for diversified small-scale post-harvest systems. Small-scale combine harvesters, affordable and simple mechanical dryers and hermetic storage systems can help to avoid delays in the post-harvest chain and thus reduce mycotoxin contamination of rice. The development of strategies to scale out these improved practices and technologies to a large number of smallholder farmers will continue to be the main challenge.

Abstract (sommario):

Aflatoxins (AFs) are toxic secondary metabolites produced mostly by Aspergillus species. AF contamination entering the feed and food chain has been a crucial long-term issue for veterinarians, medicals, agroindustry experts, and researchers working in this field. Although different (physical, chemical, and biological) technologies have been developed, tested, and employed to mitigate the detrimental effects of mycotoxins, including AFs, universal methods are still not available to reduce AF levels in feed and food in the last decades. Possible biological control by bacteria, yeasts, and fungi, their excretes, the role of the ruminal degradation, pre-harvest biocontrol by competitive exclusion or biofungicides, and post-harvest technologies and practices based on biological agents currently used to alleviate the toxic effects of AFs are collected in this review. Pre-harvest biocontrol technologies can give us the greatest opportunity to reduce AF production on the spot. Together with post-harvest applications of bacteria or fungal cultures, these technologies can help us strictly reduce AF contamination without synthetic chemicals.

Abstract (sommario):

The authors identifi ed the main factors that infl uenced signifi cantly the technological support of post-harvest processing processes over the past decades. They showed that in recent years, many farms faced the necessity to solve the problem of improving the seeds quality and reducing their losses in the process of post-harvest processing of grain in the shortest possible time.(Research purpose) To conduct a historical analysis of machine technologies for post-harvest grain processing and seed preparation and determine promising directions for their development.(Materials and methods) The authors used the historicalanalytical method applied to technical systems, in particular, to technologies of post-harvest grain processing and seed preparation. The research objects were the original works of domestic and foreign authors for more than a 100-year period and other regulatory and technical documentation.(Results and discussion) The authors presented the results of the machine technologies for postharvest grain processing and seed preparation evolution in the Russian Federation over the past 100 years. They considered the scientifi c, technological, technical and organizational issues of the machine technologies for grain processing and seed preparation development. It was determined that the scientifi c foundations for creating domestic separating machines were developed in the 30s of the last century. They noted that in 1934 the fi rst domestic mobile grain cleaning machine with a capacity of 10 tons per hour for cleaning grain and 6-8 tons per hour for cleaning seeds was created and put into production. The following key stages were identifi ed: in the 60s, an in-line technology of post-harvest grain processing was developed; by the end of the 70s, with the completion of work on the creation of units and complexes, all processes of post-harvest grain processing for the fi rst time in the country were fully mechanized.(Conclusions) The authors proved that labor productivity in the industry increased 7-10 times, the cost of grain processing decreased 2-3 times, its losses decreased, manual, unskilled labor was excluded. They identifi ed promising directions for the development of grain processing and seed preparation technologies.

Abstract (sommario):

Fruits and vegetables are highly perishable in nature and have a very short shelf-life. During different handling and marketing procedures, there is massive post-harvest loss of horticulture produce, either or both qualitative and quantitative, between harvest and consumption. Factors affecting post-harvest losses differ with topography, varieties of crops, climate, etc. and are difficult to understand. Considering the fact, the present study aims to describe the status of post-harvest losses of horticultural produce and their potential management techniques. Secondary data is used to collect the related information. The demand of high-quality horticulture produce is increasing due to its healthy nutrition. Post-harvest management of the produce includes pre- and post-harvest practices, their handling, packaging, storage, distribution, and marketing. The storage life and marketable quality of the produce can be maximized by limiting (not stopping) the respiration and transpiration through proper control of temperature and relative humidity of the produce. The right selection of packaging materials and technologies play vital role in maintaining product quality and freshness during storage and distribution. Moreover, the innovative techniques like modified active packaging, active and intelligent packaging, controlled atmospheric storage, and use of antimicrobial could extend the shelf life of produce to a significant time. This review mainly focuses on the causes of qualitative and quantitative losses of horticulture produce along with the effective measures to control the losses in Nepalese context. It emphasized on the adoption of innovative technologies to improve the storage life, marketable quality and freshness of the produce.

Abstract (sommario):

Because of public health concerns, regulators are considering requiring post-harvest treatment of halfshell and shucked oysters by wholesalers and processors. Two recently developed post-harvest treatment technologies may actually reduce the costs of producing shucked oysters, but would increase the costs of halfshell oysters. An interregional model of the wholesale oyster industry is developed to estimate the effects of treatment requirements on prices, output, and employment. If post-harvest treatment is required for all Gulf oysters, price increases are estimated to be less than 20% and, in some cases, prices decrease. Results indicate producer and consumer losses in the halfshell market are partially or more than offset by gains in the shucked market.

Abstract (sommario):

Abstract Florists’ greens are becoming increasingly important in contemporary floristry. Numerous studies conducted on cut flowers have led to the development of technologies for their post-harvest handling; however, in the case of florists’ greens they are still insufficient. Moreover, the extensive range of florists’ greens lacks leaves and the leafy culms of grasses. The aim of this study was to determine the post-harvest longevity of the leaves and leafy culms of ornamental grasses conditioned in water solutions of gibberellic acid and 8-hydroxyquinoline sulphate. The post-harvest longevity of leaves was examined in cultivars of the following species: Glyceria maxima Hartm. ‘Variegata’, Miscanthus sinensis Thunb. ‘Zebrinus’ and Spartina pectinata Link. ‘Aureomarginata’. The post-harvest longevity of leafy culms was investigated in Alopecurus pratensis L. ‘Aureovariegatus’, Chasmanthium latifolium Michx., Miscanthus sinensis Thunb. ‘Silberspinne’, Pennisetum alopecuroides L. and Phalaris arundinacea L. ‘Picta’. Conditioning in gibberellic acid had a positive effect on the post-harvest longevity and fresh weight loss and the index of leaf greenness of leaves in the case of Miscanthus sinensis ‘Zebrinus’, while conditioning in 8-hydroxyquinoline sulphate improved fresh weight loss and the index of leaf greenness of the leafy culms of Miscanthus sinensis ‘Zebrinus’, Pennisetum alopecuroides and the leaves of Glyceria maxima ‘Variegata’.

Abstract (sommario):

Despite its great potential as a food, feed and for industrial application, its processing and marketing remains economically unexploited. A cross-sectional baseline survey was undertaken in Western (Migori and Busia) and Coastal (Kilifi and Kwale) regions of Kenya between March 2013 and February 2014 using structured questionnaires to assess the post-harvest practices, opportunities and constraints in cassava processing. Results indicate that cassava processing is predominantly (58%) a women affair, males accounting for 42% with modal processors age being 32 years. Flour was the most common processed cassava product in the Coast (33%) while dried chips was highly produced in Migori and Busia in equal proportion of 43%. Other important products included cassava crisps and composite flour. Coast region had a greater diversity of products which are none existent in other regions. Most of the processing across the regions are small scale with workers mostly being the owners and activities take place in open yards with majority of these being in Busia (85 %) followed by Migori (67 %) and Coast region (57 %). Constraints during cassava processing were ranked in the following order: irregular and inadequate supply coupled with low seasonal demand for cassava and cassava products; high perishability of cassava roots; lack of value addition and processing tools; poor group dynamics, cohesion and management structure; lack of capacity building in production and processing technologies. There is very limited value addition to cassava in the study regions and hence the need to develop innovative technologies as well as new domestic and industrial products. Consumer sensitization and awareness on utilization of cassava and cassava products may be key to its promotion.

Abstract (sommario):

A study was conducted in the semi-arid Manyoni District of Central Tanzania, involving eight village communities to: (1) assess aflatoxin contamination of village grains; and (2) gain knowledge on grain food practices and habits associated with aflatoxin risk. To address the respective objectives, random immediate post-harvest (n = 134) and following 6 month or more after storage grain samples (n = 157) were screened (AFLACHECKTM -VICAM), followed by quantitative HPLC determination of samples containing ≥10 µg/kg total aflatoxins. Responses were sought from 76 randomly selected adults by a questionnaire covering pre-harvest, harvest and post-harvest practices, food preparation and knowledge on food toxins. Aflatoxin contamination was particularly more significant in maize and groundnut samples ranging up to 198 µg/kg (mean = 25.46 µg/kg) in post-harvest grains and up to 351 µg/kg (mean = 50.83 µg/kg) in stored grains, well above the maximum limit of 10 µg/kg tolerated in foods for human consumption in Tanzania. Respondent questionnaires revealed farmers: had no knowledge of food toxins; received limited extension services; did not generally use irrigation, fertilisers or pesticides; relied on inadequate harvesting, drying and storage technologies; and frequently consumed unpolished grains. Village grains in Central Tanzania may contain high concentration of aflatoxins of potential significance to community health. Existing practices and lack of aflatoxin knowledge may facilitate contamination and exposure. Therefore, village farmers in Central Tanzania may benefit from better extension services, using livestock manure as fertilizer, access to drought tolerant seeds and better grain drying and storage technologies to reduce aflatoxin risk.

Abstract (sommario):

Aflatoxin is considered a “hidden poison” due to its slow and adverse effect on various biological pathways in humans, particularly among children, in whom it leads to delayed development, stunted growth, liver damage, and liver cancer. Unfortunately, the unpredictable behavior of the fungus as well as climatic conditions pose serious challenges in precise phenotyping, genetic prediction and genetic improvement, leaving the complete onus of preventing aflatoxin contamination in crops on post-harvest management. Equipping popular crop varieties with genetic resistance to aflatoxin is key to effective lowering of infection in farmer’s fields. A combination of genetic resistance for in vitro seed colonization (IVSC), pre-harvest aflatoxin contamination (PAC) and aflatoxin production together with pre- and post-harvest management may provide a sustainable solution to aflatoxin contamination. In this context, modern “omics” approaches, including next-generation genomics technologies, can provide improved and decisive information and genetic solutions. Preventing contamination will not only drastically boost the consumption and trade of the crops and products across nations/regions, but more importantly, stave off deleterious health problems among consumers across the globe.

Abstract (sommario):

Tomato is one of the most produced and consumed olericole plants in the world, being a highly perishable fruit, which presents high levels of losses in the post-harvest period. As a form of reducing these losses, it is necessary to know the product physiology. The fruit-ripening phase involves changes in the sensorial characteristics that are unchained by ethylene, a hormone naturally synthesized within the cells and liberated in the form of gas. Ethylene can also be applied on an exogenous way, thus accelerating and making even the ripening of fruits as the tomato. On the other hand, the ripening process can be delayed with the use of 1-methylcyclopropene (1-MCP), an inhibitor of ethylene synthesis, thus prolonging the useful life in the post-harvest period. In the present investigation, with the purpose of a literature revision, in a general way, it was to demonstrate the forms of controlling the ripening of tomato fruits, in the post-harvest period, in order to prevent and reduce losses. The collected data showed that, with better care during the fruit handling and, mainly, with the use of different technologies, as the application of 1-MCP, post-harvest losses in tomato plant culture can be reduced significantly. <a href="http://dx.doi.org/10.14685/rebrapa.v4i1.116">http://dx.doi.org/10.14685/rebrapa.v1i1.6</a>

Abstract (sommario):

The study examines agricultural extension services and post-harvest technology of horticultural crop produce for smallholder farmers in West Coast Region of The Gambia. The objective of the study is to examine the effectiveness of agricultural extension services in minimizing post-harvest losses of horticultural crop produce. The instruments designed to gather the primary data include; structured interview and focus group discussions (FGD) and key informant interview supported by secondary data using official documents. The sample population consisted of three hundred and ninety-eight (398) respondents using a minimum sample calculation of Taro Yamane in which ten extension officers (10) and two extension agent heads (2) as key informants for a period of three months from September to November 2017. This study employs cluster, purposive and simple random sampling procedures to draw its population. The data was quantitatively analyzed using SPSS to run percentages, frequency distribution tables, t-test, chi-squared correlation test and factorial analysis. Qualitative data from the in-depth interviews and FGDs were also analyzed and presented appropriately. The findings of the study showed that extension services are not very much effective or proactive to post-harvest loss reduction in this region. The study recommends there is the need for continued research, development and investment programme in both extension and post-harvest technologies, effective and efficient communication to the farmers, special extension agents training on post-harvest practices among others.

Abstract (sommario):

Traditional post-harvest operation methods applied in rice fields lack advanced management knowledge and technology, which has led to post-harvest losses. We proposed the concept of Five Time (5T) management for the first time. 5T management divides the whole life cycle of rice into different growth time interval to complete process management. This paper mainly introduces the management of rice grain period, that is, the post-harvest management period, including the operation process management of harvesting, field stacking, drying, warehousing, and storing. In 2019, our research team formulated the 5T management method, which considers the entire post-harvest process, and carried out a pilot application of this method at the Jilin Rice Industry Alliance of Jilin Province. Moreover, to promote the 5T management method, our research team carried out follow-up experiments in rice production enterprises and found severe post-harvest rice losses. This paper combined a large number of literature and the basic theory research of rice post-harvest to analyze the traditional methods for post-harvest processing and the associated rice losses. By implementing the 5T management method, 4.33% of losses incurred during the T1 harvesting period could be recovered. In the T2 field period, drying rice within 48 h after harvesting could reduce losses by 2.5%. In the T3 drying period, the loss rate could be reduced by 1.6% if traditional drying methods were replaced by mechanical drying and by 0.6% if cyclic drying was implemented to prevent over-drying. In the T5 storage period, the loss rate of 7% could be reduced by adopting advanced grain storage technologies such as low-temperature storage. Overall, the rice loss rate could be reduced by 15.43%, which is equivalent to a yield of 32.68 million tonnes of rice. The important factors in each period are strictly controlled in the 5T management method to prevent the post-harvest losses caused by flawed concepts and improper management and to increase the amount of usable fertile land.

One of the important stages of growing seeds of agricultural crops is its post-harvest processing, which includes the drying process, is the main and one of the most effective methods for storing and processing agricultural raw materials. The use of vibration drying equipment is especially effective in high-tech processes taking place in the seed industry, where product moisture is the most important condition for the implementation of technology. The object of research in this article was the technological process of post-harvest processing of high-moisture pumpkin seeds, in particular drying. The purpose of the work was to analyze the current state of post-harvest processing of high-moisture pumpkin seeds and to establish promising methods and means for intensifying this process with a simultaneous increase in the quality of the final raw material obtained. The task of the work was: to review research and publications on the state of post-harvest processing of pumpkin seeds in Ukraine, to establish the features of its post-harvest dues, in particular drying, to get acquainted with the technical means and technologies for performing the technological process of drying pumpkin seeds, to establish the main disadvantages of the existing drying equipment, to determine and to propose new promising technologies and technical solutions for intensifying the drying process of pumpkin seeds with a simultaneous increase in the quality of the final raw material with minimal energy consumption and translate them into a developed model of a vibration dryer, which sequentially implements filtration and convection stages of drying. The research methodology was based on a review analysis of existing studies and publications on the state of post-harvest treatment of pumpkin seeds in Ukraine and the search for ways to intensify this process with a simultaneous increase in the quality of the final raw material obtained. In scientific work, based on the results of the study, it was found that the existing grain drying equipment does not meet the requirements for drying high-moisture pumpkin seeds, therefore there is a need for the development, research and implementation of energy-efficient schemes and structures. The existing samples of domestic equipment for post-harvest processing of high-moisture pumpkin seeds are morally and physically obsolete, do not provide flexibility in the execution of the technological process, are energy- and metal-intensive and cannot be used in processing lots of seed material. The proposed design of a vibrating dryer, which sequentially implements filtration and convection stages of drying pumpkin seeds. The developed installation provides an intensification of this process with minimal energy consumption while increasing the quality of the final raw material obtained.

Abstract (sommario):

This study discusses a plant breeding and seed system recovery. According to the 2013 information, over 3000 seeders with colters of strip cropping were upgraded, which worked in 64 regions of the country. Simultaneously with the work on the modernization of the seeders for strip cropping, Russian Institute of Mechanization together with LLC “Tekhtsentr Laishevo” and “KhaRaSha” developed a design specification on the universal seeder SUZT 4of strip cropping with 4 meter width and a design specification on unified with it breeding and farming seeder SFS -2 with 2 meter wide. The pilot seeder SUZT-4 was designrd in LLC “KhaRaSha” and in 2012 it was successfully held acceptance tests with the recommendation on production at the Kirov Machine Testing Station. This seeder is designed for strip sowing of cereals, legumes, small-seeded crops and grass with simultaneous application of mineral fertilizers, as well as for early spring narrowband sowing of sparse winter crops and perennial grasses and subsurface mineral fertilizers plant nutrition. In 2013 there have manufactured a pilotmachine of breeding and farming seeder SFS-2 and it was transferred to Machine Testing Station for carrying out acceptance tests. The speeding up the implementing these seeders allow to carry out technological operation of planting crops in a highly effective stripping way with a significant increase of productivity and with high quality seeds. On spring wheat crops, where the seeds were prepared by car SMVO and sowing performed by seeders with ODA colters of strip cropping, the field germination ranged was from 92.5 to 95.6%, which is 4.5-8.1% higher, than seeds, obtained without isolation of their specific weight and drill sowing by double disc coulters. As a result, the higher harvest is formed by 8-10 centner per hectare and more. Additional 1.0 million tons of crops were reaped from improved seeds quality. Thus, the use of universal seeders with single disc - hoe colters and seed-crop cleaning machines SMVO is the most affordable way to increase the crops yield and seed quality for all farms. Key words: selection and seed-farming, Seed-growers association, seed-crop cleaning machine, processing of grain and seed, a seeder with disc-hoe colters, strip cropping .

Abstract (sommario):

SUMMARYFresh fruits and vegetables have a short post-harvest life and are prone to post-harvest losses due to mechanical injury, physiological causes and decay. Low-temperature storage is widely used as post-harvest treatment applied for delaying senescence in vegetables and ornamentals and ripening in fruits, upholding their post-harvest quality. But the refrigerated storage of tropical and subtropical crop plant species provokes a set of physiological alterations known as chilling injury that negatively affect their quality and frequently renders the product not saleable. Membrane damage and reactive oxygen species (ROS) accumulation are the main adverse effects of chilling injury impact in sensitive horticultural products. The chilling injury tolerance of certain plant species is attributed to their ability to accumulate heat-shock proteins (HSP). The beneficial action of HSP in chilling tolerance is due to their chaperone activity but, besides this biological function, small HSP (sHSP) are able to function as membrane stabilizers and ROS scavengers, or synergistically with cell antioxidant systems. Also, biosynthesis of osmolytes such as raffinose and proline is under the regulation of heat-shock transcription factors (HSTF). These molecules are critical for osmotic adjustment since low temperatures also provoke a secondary osmotic stress. The use of biotechnological strategies can be envisaged, with the aim of generating engineered crop plants of horticultural interest to induce the production and action of HSP and HSTF, in order to assure the beneficial effects of these proteins in promoting chilling injury tolerance during their post-harvest refrigerated storage. In particular, induction of HSTF expression using biotechnology has significant potential and interest for reducing the impact of chilling injury on sensitive produce, avoiding the practical difficulties of applying the classic post-harvest technologies based on heat treatment.

Abstract (sommario):

Objective of the study was to evaluate the effects of different post-harvest treatments on bio-chemical characters and diseases of litchi (Litchi chinensis Sonn, var. Bombai). The experiment consisted of two factors. Factor A: Temperature viz. T1: Ambient temperature, T2: 4ºC temperature; Factor B: PP bags (Polypropylene bag) viz. P1: Control (unwrapped), P2: 50 micro meter (µm) PP bag, P3: 75µmm PP bag, P4: 100µm PP bag. The experiment was conducted in completely randomized design (CRD) with three replications. Significant variation was observed in total soluble solid, PH of fruit pulp, vitamin c content, percent disease incidence and disease severity during the storage period. TSS contents increased up to the 6th day of storage and there after declined. pH values were maximum (4.14) in the fruits kept in 100µ polypropylene bag at ambient temperature. Vitamin C continent decreased with the increase of storage period. Disease incidence and severity progress with the storage period. Among the treated and untreated fruits, 75µm pp bag at low temperature (4ºC) treatment exhibited better storage performance. More research should be conducted by using other litchi cultivar like Bedana, China-3 etc. Various technologies have been devised to minimize the post-harvest losses of litchi, one of such technologies is the use of PP bag & low temperature.

Abstract (sommario):

Increase of vegetable oils production provides for the further improvement of oily raw materials storage technology. It is known that technological quality of oilseeds is formed in close relation to its morphological characteristics, as well as peculiarities of biochemical processes inside of seeds, depending on external conditions and their development phase. The paper presents comparative results of researches of dynamics of qualitative and biochemical parameters of rape and brown mustard oilseeds with and without post-harvest ripening during storage. Research has shown that in order to produce high-quality fat-and-oil products, oilseeds must necessarily undergo the ripening process in artificial conditions, where the seeds are taken after they reach ripeness level enough for harvesting. Considering that the main period of oilseed storage is mainly destructive, seeds that have not undergone post-harvest ripening have active disintegration process even in case they are stored in perfect conditions. This process considerably reduces quality of seeds and their storage period. Based on the researches, practical recommendations were developed for post-harvest ripening and storage of oilseeds. The presented research data can be used to optimize the existing technologies of oily raw material post-harvest ripening and storage, to increase process quality of processed seeds and obtain high-quality fat-and-oil products.

Abstract (sommario):

Withering is a practice traditionally used in various regions to produce sweet or dry wines. During withering there is an increase in sugar content but also a modification in volatile compound profiles. Controlling metabolic changes through the dehydration process to obtain wines with desired characteristics is therefore a challenging opportunity. The effects of two different withering technologies, post-harvest or on-vine with blocked sap vessel flow, on the volatile profile of young and aged Corvina red wines was investigated. The results showed that modulation of wine aroma due to the withering process is associated with fermentative metabolites, such as esters, higher alcohols, and acids, as well as grape-related compounds such as C6 alcohols, terpenes and norisoprenoids. Significant differences were also found by comparing the two withering techniques. Post-harvest in a traditional “fruttaio” warehouse wines showed higher content of ethyl acetate, ethyl butanoate, β-citronellol and 3-oxo-α-ionol, whereas post-harvest withering on-vine increased β-damascenone in wines. The type of withering technique has an influence on the evolution of some aroma compounds during the aging of wine, among them linalool, (E)-1-(2,3,6-trimethylphenyl)buta-1,3-diene (TPB), n-hexyl acetate, ethyl acetate, ethyl 3-methylbutanoate, 3-oxo-α-ionol and β-damascenone.

Abstract (sommario):

Sweetpotato (Ipomea batatas) is a versatile crop that serves the roles of food and nutrition security, cash crop in both raw and processed forms. It is a source of livestock feed and has great potential as a raw material for industrial processing. The potential of sweetpotato has been greatly under exploited by the fact that it has been regarded as a poor man’s food and is mainly grown under marginal conditions for subsistence by most producers, who are rural small-scale farmers in developing countries, such as Kenya and Uganda. Losses in the highly perishable root crop and its leaves are exacerbated by lack of appropriate postharvest knowledge, technologies and facilities. Inadequate information on available cultivars also limits the maximum utilization of the crop and leaves. The current review examines production potential, post harvest handling practices, marketing, and physicochemical and nutritional properties of sweet potatoes.

AbstractA hedonic price function is developed for estimating the implicit prices for selected quality characteristics of fresh tomatoes at three points in the marketing season. The estimation of this function, proposed as a method of evaluating changes in the post-harvest system, is accomplished using a flexible functional form. Those quality characteristics that most affect the price of tomatoes can help determine the economic feasibility of alternative handling techniques or new technologies.

Abstract (sommario):

Abstract Maize is harvested after reaching maturity when its moisture content generally ranges from 30 % to 34 %, while the optimum moisture for storage is around 14-15 %. This moisture is usually achieved by thermal drying. Apart from initial moisture, the total drying time is affected by the temperature of the drying environment, atmospheric conditions and properties of the dried material. The present paper provides a description of the process of moisture loss and subsequent drying rate of grain maize from various growers. Obtained results are processed in a tabular and graphical form. After 30 minutes of drying, all the maize samples (10 samples two times in total) reached a moisture of 14 % and less, whereas 6 samples already after 20 minutes of drying. The rate of moisture loss was proportional to the initial moisture content. The drying of grain maize is considered one stage of the technological procedure in post-harvest treatment. Moreover, it is an essential preventive measure for wet harvest. Contemporary technologies of maize drying in modern dryers favourably influence the energy consumption in the process while maintaining the qualitative parameters of the dried material.

Abstract (sommario):

Fruit growing contributes to Brazilian socioeconomic growth, both as a source of food for the population and in the generation of employment and income. However, the production chain incurs significant negative impacts, mainly due to post-harvest losses. The objective of the current study was to estimate the post-harvest losses of fruits, occurring in the retail markets of Anapurus, Belágua, Mata Roma, São Benedito do Rio Preto and Urbano Santos (Maranhão State). The study was carried out with visits to 45 commercial establishments, and the deployment of a questionnaire regarding post-harvest losses of 12 fruits. It is concluded that, in decreasing order, losses were: avocado (11.76 ± 0.09%) > papaya (11.65% ± 0.02) > banana (10.82 ± 1.75%) > grape (10.08 ± 0.06%) > passion fruit (9.28 ± 0.04%) > pineapple (8.62 ± 0.04%) > watermelon (8.48 ± 0.05%) > mango (8.00 ± 0.18%) > orange (7.12 ± 0.10%) > apple (6.68 ± 0.07%) > pear (6.52 ± 0.03%) > melon (4.32 ± 0.01%). Physiological disorders were the main cause of losses, with estimated losses being up to 10.62%. It is suggested that losses could be reduced with: better hygiene in commercial environments, effective planning of the quantities offered, and the adoption of low cost technologies for the conservation and refrigeration of temperate fruits. Some public initiatives, such as the increase in availability of training courses, improvement of roads in the rural areas of the Chapadinha Microregion, and encouragement of the expansion of fruit growing in Maranhão, may lead to improvements, with direct benefits to society in general.

The use of fractional technologies for post-harvest treatment and processing of grain heap delivered from field with further special purpose use of grain fractions leads to a significant increase in grain production efficiency. (Research purpose) Developing a fractional technology for post-harvest treatment and processing of grain with crushing and preservation of feed grain fraction and designing a technological line and machines for it. (Materials and methods) The authors have analyzed the technological level and developed a fractional technology for grain post-harvest treatment and processing by crushing with subsequent preservation of the feed grain fraction. They have offered a technological line and presented the design and technological parameters of the corresponding technical means (МЗУ-20Д - grain cleaning universal machine, МПО-30ДФ - preliminary grain cleaning machine with fractionation, ПЗД-3,1, ПЗД-10 – two-stage grain crusher). (Results and discussion) The authors have designed, manufactured and tested a universal grain-cleaning machine МЗУ-20Д. It efficiently cleans grain material coming from the field after its threshing by combine harvesters, and divides it into fractions: seed and feed grain – 60-70 percent, waste material - up to 10 percent, grain fodder - up to 40 percent. Further on, the grain is sent for crushing (for wet grain), followed by preservation and hermetic storage of the products obtained before their feeding to animals. Tests have shown that the developed feed preparation machine efficiently performs the technological process. The authors have developed a two-stage grain crusher (ПЗД-3,1), performing the crushing of grain material in two stages by three rollers, followed by preservation (for wet grain) of the feed grain fraction. (Conclusions) It has been established that the use of the new fractional technology and equipment contributes to an increase in grain cleaning productivity – by 30-40 percent, and the estimated annual economic effect of the renovation is 400,000 rubles. The estimated annual economic effect of the use of the two-stage grain crusher (ПЗД-3,1) has proved to be more than 60 thousand rubles, and the level of production intensification has increased by 26 percent as compared to the MURSKA crusher produced in Finland.

Abstract (sommario):

One of the problems in the seed production of pasture forage plants is low seed germination. Existing pasture improvement technologies and technical means for seed production, harvesting, post-harvest handling, and storage of pasture forage plants are analysed. Suggestions for improving seed germination have been developed: it is advisable to place the seed crops between the forest belts; to improve seed germination, it is necessary to make a preliminary harvest of seed crops with spreading the mass on the stubble; the mechanised collection of seed heaps using a rotary mower with an active heap separator increases the germination rate by reducing mechanical damage to the seeds and enriching the soil with organic matter; the seed sowing process has a positive effect on the germination rate of the seed produced, in addition to reducing cleaning costs.

To reduce the accumulation of toxic substances in tubers in 2014–2016 the author studied biological methods of fertilizers application and plant protection in black earth forest-steppe region under the conditions of high-intensity potato cultivation technology along with drip irrigation. The introduction describes the importance of potato in the diet of population and lists the environmental issues that arise as a result of enhanced using of chemicals during crop cultivation. The doses of mineral fertilizers in experiments were introduced separately and in combination with a bioameliorant: 1) without fertilizers (control site); 2) N60P90K60; 3) N90P135K90; 4) N120P180K120; 5) biological ameliorant – white mustard, post-harvest green manure; 6) bioameliorant + N60P90K60; 7) bioameliorant + N90P135K90; 8) bioameliorant + N120P180K120. Chemical insecticide Aktara and biological preparations Fitoverm, Akarin were used to protect potatoes against Colorado potato beetles. Insecto-fungicide Celest was used to treat seed tubers against fungal diseases. During growing season the author used fungicides Profit Gold, Ridomil Gold against fungal diseases, against weeds – Zenkor and Remus. High yield of potato environmentally friendly considering nitrates was obtained by means of simultaneous application of N90P135K90 and white mustard green mass. Tuber yield was 40.4 tonnes per hectare compared to 22.7 tonnes per hectare on the control site, and nitrate content was 111.3 mg while maximum permissible concentration (MPC) is 250 mg/kg. According to MPC established in the Russian Federation, for childrenʼs and dietary nutrition fertilizer dose should not exceed N60P90K60 in combination with a bioameliorant and a biological plant protection system. Safety interval (period between plant treatment and harvesting) for chemical insecticides is 35–40 days; fungicides – 20 days; herbicides (depending on their type) – 55–70 days. The production of ecologically clean potato according to EU standards was achieved only by means of using post-harvest green manure as a fertilizer, applying biological insecticides and Celest preparation within the framework of protecting plants against pests and diseases.
