Tofu industries produce waste water containing high organic contents and suspendid solid which is harmful if directly discharged to the environment. This waste can lead to disruption of water quality and lowering the environmental carrying capacity of waters around the tofu industries. Besides, the tofu waste water still contains high nitrogen contents which can be used for microalgae growth. This study was aimed to reduce the pollution load (chemical oxygen demand-COD) of tofue wastewater by using ozone treatments and to utilize nutrients in treated tofu waste water as medium growth of microalgae. The result showed that the reduction of COD by implementation of ozone treatment followed first order kinetic. Under variation of waste concentrations between 10-40%, the degradation rate constant was in the range of 0.00237-0.0149 min-1. The microalgae was able to grow in the tofue waste medium by the growth rate constants of 0.15-0.29 day-1. This study concluded that tofu waste was highly potent for microalgae growth.

Com este trabalho, objetivou-se avaliar a composição química e aspectos bioquímicos de soja comum, comum branqueada e livre de lipoxigenases e o efeito do processamento dos seus respectivos extratos de soja e tofus. A composição centesimal das cultivares de soja comum e livre de lipoxigenase não se diferenciaram (p>0,05). Alterações na composição centesimal e de minerais dos extratos de soja e dos tofus foram atribuídas ao tratamento térmico (98 ºC/5 minutos) a que foi submetido o grão de soja comum e à etapa de maceração dos grãos, ficando evidente que algumas substâncias hidrossolúveis, foram migradas para a água de maceração dos grãos; o branqueamento na soja comum no início do processamento reduziu o teor de alguns minerais do extrato de soja (leite de soja), bem como no tofu. Ficou evidente as perdas de isoflavonas com o processamento na obtenção do tofu, na ordem de 38% no de SC, 31% no de SCB e 56% no de SLL. O processamento térmico utilizado para obtenção dos tofus foi suficiente para eliminar a atividade dos inibidores de tripsina em 79% do tofu de soja comum, 81% no tofu de soja branqueada e 82% nos tofus de soja livre de lipoxigenase.

The antioxidant and hepatoprotective properties of tofu using acetaminophen to induce liver damage in albino rats were evaluated. Tofus were prepared using calcium chloride, alum, and steep water as coagulants. The polyphenols of tofu were extracted and their antioxidant properties were determined. The weight gain and feed intake of the rats were measured. The analysis of serum alanine aminotransferase (ALT), alkaline phosphatase (ALP), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) activities and the concentrations of albumin, total protein, cholesterol, and bilirubin were analyzed. The result reveals that the antioxidant property of both soluble and bound polyphenolic extracts was significantly higher in all tofus, but the steep water coagulated tofu was recorded higher. Rats fed with various tofus and acetaminophen had their serum ALP, ALT, AST, and LDH activities; total cholesterol; and bilirubin levels significantly (P<0.05) reduced, and total protein and albumin concentrations increased when compared with basal diet and acetaminophen administered group. Therefore, all tofus curdled with various coagulants could be used to prevent liver damage caused by oxidative stress.

During this time to identify pure and formalin tofu based on color and aroma involving human taster. But this tofu tester still has weaknesses such as subjective. Besides that, the standard chemical analytical methods requires a high cost and need expertise to analyzing it. Basically aroma of tofu is determined by volatile compounds such as heksanal, ethanol, and 1-hexanol, while aroma of formalin tofu is determined by volatile compounds such as OH, CO, and hydrocarbon. Electronic nose based on unselected gas sensor array has the ability to analyze samples with complex compositions that can be known characteristics and qualitative analysis of the samples. Stimulus aroma is transformed by electronic nose into fingerprint data then it is used by feature extraction process using the differential method. The results of feature extraction is used to process the back propagation neural network training to obtain optimal parameters. The parameters have been optimized is then tested on a random tofus. Based on test results, ANN-BP can identify samples with 100% accuracy rate so that the identification of a pure tofu and tofu formalin with electronic nose using back propagation neural network analysis has been successfully carried out.

This pneumatic system tofu press machine is a press machine that is used to compress tofu starch with a capacity of 50 kg to make tofu that is ready to be marketed. The pneumatic system tofu press machine is made to make it easier to press tofu. Previously, tofu was pressed manually, namely by using a stone as a tofu press which resulted in the length of the tofu compaction process. Pressing with stones can also cause work accidents. This tofu press machine uses pneumatics as a punch driver which will press the tofu. The way this tofu machine works is by pressing the on button on the machine then the punch will move down towards the tofu essence and press the tofu. Punch paused for a moment to make sure the tofu blended in perfectly. Then press the off button on the machine to return the punch to its original position. This pneumatic system tofu press machine can reduce work accidents, lighten work, shorten processing time and is also more hygienic because it uses air as a punch driver.

Soybean breeding programs targeting tofu production must identify cultivars that are well suited for making tofu. A small-scale (SS) test of tofu texture was developed to evaluate breeding lines. The SS tofu test was developed to complement the larger scale Harrow tofu test but to use smaller samples of seed and soymilk to make tofu. The SS tofu test uses both magnesium chloride (MgCl2) and glucono-delta-lactone (GDL) coagulants to produce tofu samples of 20 mL. In comparisons of the SS and Harrow tofu texture tests, using lines with varying protein subunit profiles, both tests ranked lines similarly. In plant breeding trials, the SS tofu test was useful in ranking varieties for tofu texture. Multiple-year testing should be used for a thorough evaluation of varieties. When the SS tofu test was used with a population of lines with a wide range of seed protein, GDL-coagulated tofu texture was independent of seed protein content; however, MgCl2-coagulated tofu texture was moderately inversely correlated with seed protein. With the SS test, it may be best to compare tofu texture within groups of lines with similar seed protein levels. The SS tofu test is useful to test tofu texture of breeding lines using small amounts of seed.

A large quantity of bean dregs is produced by the production of tofu and treated as animal feed or plant fertilizer, which could cause environmental pollution. The purpose of this study was to use commercially available lactone tofu to compare the effects of innovative preparation methods of high-fiber tofu, where the innovative methods used partial de-slagging followed by the addition of soybean residue cellulose to prepare high-fiber tofu. The results showed that there were no significant differences among lactone tofu samples made with 5% cellulose, 10% cellulose, or 15% cellulose and the commercially available lactone tofu during the water-holding capacity and chroma analysis. Texture indices showed that lactone tofu with 10% cellulose was similar to the commercially available lactone tofu in chewiness and hardness, and lactone tofu with 15% cellulose was similar to the commercially available lactone tofu in adhesiveness and chewiness. Magnetic resonance imaging displayed that lactone tofu with 10% cellulose had better water retention and higher moisture content. Gel electron microscopy showed that lactone tofu with 10% cellulose achieved a better gel network, and the bean dreg cellulose had less influence to a certain extent. Volatile organic compound testing by GC-IMS method indicated that the lactone tofu with 10% cellulose had more volatile organic compound content. In conclusion, these results demonstrated that lactone tofu with 10% cellulose had the best market competitiveness in ensuring the quality of high-fiber tofu.

Feed is important component in the livestock industry. Feed quality provide optimal production in this industry, and vice versa. The cost of feed can reach 60-85% of the cost of production, so the emphasis on feed costs needs to be considered. Industrial waste has the potential to be used as a source of feed, one of which is waste from a tofu factory, namely tofu dregs. Tofu dregs contain high crude protein and high palatability value. The high potential of tofu dregs to be used as a source of animal feed, prompted researchers to conduct a study on the potential use of tofu dregs from the Lin's Kuok tofu factory as a source of protein in beef cattle rations. The results showed that Lin's Kuok Tofu Factory's production of tofu dregs in % DM was 31.44 Kg/day CP, CP 9.53 Kg/day, TDN 24.49 Kg/day. The usability of tofu dregs from Lin's Kuok Tofu Factory is (DM) 5.03 AU, CP 14.44 AU and TDN 5.69 AU.

The service team of the Food Science and Technology Study Program, Faculty of Agriculture along with the Community Service Institute of Universitas Sumatera Utara has conducted service activities for partner which are SMEs of tofu chips in the Hamlet II of Pisang Pala Village, Bangun Purba District, Deli Serdang Regency, North Sumatra Province between May and October in 2018. The partner named Roemah of Al Fatih, which produces raw tofu from soybeans, fried round tofu, and tofu chips. The main problem faced by the partner that began production in 2016 was the difficulty when making spherical of tofu dough as the starting material for tofu chips. So far, the partner has carried out the process of rounding out the dough manually using hand which took a long time. The service team offered a solution by granting a tofu rounder machine from stainless steel using electrical energy. Furthermore, the service team tested the production capacity of the tofu rounder machine and the conventional method (using hand). For the quality of round raw tofu (specific gravity and appearance of the product) and the quality of tofu chips, the team analysed and compared both products which were produced by hand and by machine. The results obtained the use of the tofu rounder machine can increase the capacity of round tofu production significantly, improve the appearance of round tofu products to be denser, and increase the value of preference for the texture of tofu chips produced. The grant of the tofu rounder machine is expected to help the partner for working up the company's profits in the future.

Soybeans are an inexpensive, high-quality protein source. Soybeans have long been a staple of the human diet in Asia, especially as tofu, which is prepared from soymilk. In this study, tofu was made using a new production method which includes hydrothermal cooking (HTC) and rennin-pepsin coagulant. The effects of the addition of gallic acid to the slurry during tofu processing were studied. Tofu was made from two soybean genotypes: Lana and Balkan. The observed genotypes are characterized by relatively high content of total proteins in flour, from 45.88% to 48.83%. The prepared tofu samples are characterized by extremely high content of total proteins (52.17% - Lana tofu and 56.08% - Balkan tofu). The presence of gallic acid significantly affects the solubility of tofu protein. The applied modifications of traditional procedure of tofu production significantly improved sensory properties of soybean protein products.

This study aimed to investigate the properties of acidic whey tofu gelatin generated from two acidic whey coagulants by pure fermentation of Lactiplantibacillus paracasei and L. plantarum, as well as the characteristics of acidic whey tofu. The optimal holding temperature and the amount of coagulants added were determined based on the pH, water-holding capacity, texture, microstructure, and rheological properties of tofu gelation. Then, the differences in quality between tofu produced by pure bacterial fermentation and by natural fermentation were investigated under optimal tofu gelatin preparation conditions. The tofu gelatin presented the best texture at 37 °C with a 10% addition of coagulants fermented by both L. paracasei and L. plantarum. Under these conditions, the coagulant produced by the fermentation of L. plantarum resulted in a shorter formation time and stronger tofu gelatin compared with that produced from L. paracasei. Tofu produced by the fermentation of L. paracasei had higher pH, less hardness, and a rougher network structure, whereas tofu produced by the fermentation of L. plantarum was closer to tofu produced by natural fermentation in terms of pH, texture, rheology, and microstructure.

Background: Tofu industry in Indonesia commonly used fermented whey as coagulant. There is a lack of study about tofu producing process which used fermented whey. Generally, the society determine the tofu quality from the texture, however, the industry itself tend to produced tofu rendement. In the tofu industry, the yield and texture of tofu is a very important process parameter. The yield and texture are influenced by various factors, such as the soybean extraction process, cooking temperature, coagulation pH, length of coagulant addition, intensity of coagulant addition, or duration of shaping and pressing. However, every tofu factory applies different levels for each factor. This condition causes the variation in the characteristics of tofu, especially with regard to its texture and yield. Objective: This study aimed to determine the factors that affect the quality and quantity of tofu. Methods: The survey study was conducted among the 21 tofu factories using fermented whey as the coagulant. Results: Based on the survey results, there were seven variables that determine the yield of tofu; the soybean type, soybean and water ratio, pH of fermented whey (coagulant), coagulation temperature (°C), coagulation pH, intensity of coagulant addition (time), and duration of molding (minutes). Conclusion: The six factors that influenced the tofu texture were soybean type, soybean and water ratio, coagulation temperature (°C), coagulation pH, coagulation time (minutes), and duration of molding (minutes).

Tofu, one of the most important products made from soymilk, is obtained through a coagulation process performed with various coagulants (acids, salts and, enzymes). In this study, innovative tofu samples were produced using the grape pomace (GP) powders of different varieties (Barbera, Chardonnay, Moscato, and Pinot Noir) with different origins (fermented and distilled) at two concentration levels (2.5% and 5% w/v) as coagulants, and comparisons with traditional tofu were made. Physicochemical characteristics, phenolic contents, radical scavenging activity levels, textural properties, and consumer acceptability were evaluated. The moisture, protein content, and pH levels of GP tofu samples were slightly lower than those of traditional tofu. Regarding textural parameters, except for hardness, all other parameters were significantly lower in GP tofu samples, with differences due to GP concentration. The colours of GP tofu varied from amber-yellow to violet according to the GP origin. The blue-violet colours were observed predominantly in tofu samples obtained with Barbera and Pinot Noir GPs, while the other GP tofu samples showed amber-yellow colours. The concentrations of polyphenols were 2–10 times higher than in traditional tofu, while the radical scavenging activity levels were 9–80 times higher. The GP tofu samples were favoured by consumers, with small differences among the GP varieties.

Efforts to prevent and overcome various degenerative diseases can be realized by developing functional foods that are known as natural or processed foods containing bioactive components that have the potential to improve health status. One of whole foods that has potency to be developed as functional food is soft tofu dessert. Soft tofu dessert has two main components which are soft tofu and ginger drink. However, there is lack of references providing the evidence of the characteristics and health benefit or soft tofu dessert. This study provide data to support the development of soft tofu dessert as a whole food that has optimum characteristic and contains benefit for health as well. The research objectives were to test radical scavenging capacity of soft tofu dessert and its component by implementing DPPH method. Antioxidant capacity of the samples was observed by using DPPH method (517 nm). Ranges of concentration were observed to determine IC50 of each sample. IC50 value presents the inhibition of 50% DPPH radical by samples. The values of IC50 for ginger water extract, ginger drink, soft tofu, and soft tofu dessert were 1592.40±22.30 ppm, 2764.26±90.29 ppm, 24657.50±2483.11 ppm, and 3356.04±415.54 ppm respectively. This result showed the best radical scavenging capacity was ginger water extract > ginger drink > soft tofu dessert, and > soft tofu. Soft tofu dessert performed better scavenging capacity than soft tofu itself, but still performed the lower capacity compared to ginger water extract and ginger drink.

Processed soybeans such as tempeh and tofu are some of the foods that the people of Indonesia favour. The Tempe and Tofu processing factory produce tofu with the essential soybean ingredients as much as 17 kg every day. The tofu production process starts from soybean immersion, grinding, boiling, filtering, compaction, moulding, cutting, to frying tofu. Production activities from the tofu industry will certainly produce solid and wastewater. These wastes can have a negative impact on the environment. Therefore, the waste must be managed and treated correctly to create an environmentally friendly industry and improve environmental quality. Tofu industry waste management and treatment can be done by identifying the generation of waste that is a priority to be treated and choosing waste treatment technology. There are three alternatives for wastewater treatment from the tofu industry: the chlorine in wastewater, ponds by forming biofilms using biofilter media, and Trickling Filters.

One of the typical foods consumed daily as a side dish by the community is tofu. Tofu is made with soybean as raw material which is crushed into a pulp and protein coagulated to form the texture of the tofu. Until now, soybeans are the main raw material for making tofu. In fact, according to the analysis, the projection of soybean demand is much higher than the supply of soybeans that can be produced, so that the potential to meet the demand for soybeans will be carried out through imports. Imported soybeans will affect the selling price of tofu because the price of imported soybeans varies depending on the exchange rate and under certain conditions, the price of imported soybeans is cheaper. If this condition continues, the original tofu made from local soybeans will be crushed by the use of imported soybeans, farmers will lose because local soybeans are not selling well, tofu traders suffer a lot, the price of tofu varies, and it is possible to reduce the original taste of local tofu. Therefore, it is necessary to have raw materials that can substitute soybeans in making tofu, including cowpeas. This study aims to determine the combination of cowpea-soybean formulations and coagulation ingredients to produce the best physicochemical quality of tofu. The best treatment is the use of a combination of 90% soybeans with 10% cowpeas and vinegar as a coagulant for protein. The treatment resulted in tofu with levels of protein, fat, fiber, carbohydrates, water, and ash, respectively 12.10%; 2.8%; 0.6%; 9.29%; 71.56%; and 3.64%.

Soybeans are a good source of protein and functional nutrition for humans and are used in the production of many foods, such as soymilk and tofu, which are popular in Asia. Soymilk is a beverage with a milky appearance and is produced by grinding soybeans in water; this raw soymilk is then filtered and heated. Soymilk can be used to produce tofu, a gelatinous food, in a process that generally involves coagulating, forming, and pressing soymilk. Tofu is also a source of functional ingredients, such as isoflavones, that have received much attention for their antioxidant properties. These isoflavones bind to soy protein to form soy protein–isoflavone complexes in tofu. In this review, we examined the processing, gelation and functional components of tofu. First, we introduced novel processing technologies (such as thermal and nonthermal processing) and hydrocolloids that affect the rheological property and texture of tofu. Then, because the coagulation and gelation of soymilk are important steps in the tofu manufacturing process, we also described detailed coagulation and gelation mechanisms of soybean proteins in tofu. Finally, we described the functional compounds and ingredients in tofu. This review provides basic knowledge for the further application of novel processing technology in tofu processing.

Leisure dried tofu (LD-tofu) was prepared using two different marinating processes: the repeated heating method (RHM) and the vacuum pulse method (VPM). The quality characteristics and bacterial community succession of LD-tofu and the marinade were evaluated. The results showed that the nutrients in LD-tofu were easily dissolved into the marinade during the marinating process, while the protein and moisture content of RHM LD-tofu changed most dramatically. With the increase in marinade recycling times, the springiness, chewiness and hardness of VPM LD-tofu increased significantly. The total viable count (TVC) of the VPM LD-tofu decreased from the initial value of 4.41 lg cfu/g to 2.51–2.67 lg cfu/g as a result of the marinating process, which had a significant inhibitory effect. Additionally, 26, 167 and 356 communities in the LD-tofu and marinade were detected at the phylum, family and genus levels, respectively. Pearson correlation analysis showed that Pseudomonadaceae, Thermaceae and Lactobacillaceae were closely related to the quality characteristics of LD-tofu, whereas Caulobacteriaceae, Bacillaceae and Enterobacteriae were closely related to the marinade. The present work provides a theoretical basis for the screening of functional strains and quality control in LD-tofu and marinade.

Abstract Tofu is one of the staple foods that are in demand by the wider community due to its high nutritional content, especially protein, and has quite a lot of processed variants. Therefore, the production of tofu must be developed to obtain the best quality, and adequate quantity of production and at the same time, become a product with an environmentally friendly production process. There are still many conventional tofu factories found in Merauke. However, its production process is still a little concerned about environmental aspects. This study aims to identify inputs, outputs, and environmental impacts of the tofu product life cycle, determine potential sources of impact (hotspots) and recommend improvement scenarios. The Life Cycle Assessment (LCA) method is used to estimate and analyze the potential environmental impacts that occur due to the production of 1 kilogram of tofu products at ABC Factory in Merauke. The environmental impact produced by this tofu product is the potential for global warming, so the amount of greenhouse gas emissions that occur will be analyzed. In addition, energy efficiency will be calculated, and conclusions and interpretations will be drawn from the previously analyzed inventory results. The limitation of the system used in this study starts from the soybean cultivation process, transportation of raw materials, and the process of making tofu at ABC Factory. From the results obtained that tofu with local soybean generates GHG emissions is 0.337 kg CO2-eq per kg of tofu, while tofu with imported soybean is 0.801 kg CO2-eq per kg of product. Energy efficiency is indicated by the Net Energy Value (NEV) and the Net Energy Ratio (NER) of the tofu products. The Tofu with local soybean has NEV is 3.529 MJ, while tofu with imported soybean is 0.961 MJ. The value of NER>1 for both tofu products. From the results of inventory analysis, several alternatives can be recommended to reduce the environmental impact that occurs.

One of the high-quality processed vegetable food ingredients is tofu. Tofu is made from processed soy milk with a thick texture and molded according to the right nutritional amount. White tofu is the most popular of the various forms of tofu available. Today, tofu producers have taken manipulative actions to anticipate production losses by including preservatives in the mix of ingredients used to make tofu. Most of the tofu production centers provide additional ingredients in the form of preservatives such as formalin to reduce losses from damage to the tofu they produce. The presence or absence of formalin in food can be detected using a unique component found in dragon fruit peel called anthocyanins. The methodology applied in this research is a simple and direct one, with primary data collected in the form of testing samples of white tofu collected from numerous traditional markets in the Banten area (up to ten samples). The aim of the research is to identify formalin in white tofu discovered in numerous traditional markets in Banten using natural component extracts, including dragon fruit peel extract. The results stated that there were two positive samples containing formalin and eight negative samples; the presence of formalin in tofu was indicated by a red color on the tissue. Sellers or customers can detect formalin simply by utilizing dragon fruit, allowing them to avoid formin which is harmful to health, with a simple and low-cost method.

Ploso Village, Jati District, Kudus is one of the tofu production centers in Kudus, there are about 30 tofu industries. The existence of a tofu factory will cause waste problems, both liquid waste, and solid waste. The percentage of solid waste in the form of tofu dregs is around 70% and is currently not widely used. This solid waste will cause environmental pollution if it is not used immediately. Tofu waste contains nitrogen, phosphorus, potassium, magnesium, calcium, iron, and organic carbon (C) which can be used as compost to increase soil and plant fertility. Community service activities with the title "Utilization of Tofu Dregs Waste into Compost in the Tofu Industry in Ploso Village, Jati District, Kudus Regency" resulted in a model of utilizing tofu solid waste into compost that can be used for plant cultivation in Ploso Village or on a larger scale it can be commercialized so that it can increase people's income.

Tofu waste is generally used for animal feed, potential for biogas production, and as a traditional food. Opportunities for the use of tofu waste are very wide because of the high nutrient content of tofu waste. Tofu waste nutrient content has the potential to be utilized as an alternative medium for mold growth. One type of mold that is often analyse in the laboratory is from the genusPenicillium. This study aims to determine the composition of an alternative growth media from tofu waste for Penicillium spp. This study is an experimental laboratory with the independent variable of tofu waste mass (0,1,2,3,4,5 gr) and sucrose mass (0,2,4,6 gr), while the dependent variable observed from this study includes the amount Penicillium spp colonies and their growth characteristics in tofu waste media. Both dependent variable observed then compared with Potato Dextrose Agar (PDA) as commercial media Tofu waste composition used in this study were (gr/100mL) : tofu waste (0, 1, 2, 3, 4, 5 gr), sucrose (0, 2, 4, 6 gr), aquadest (100mL), and agar powder (1,5gr). Statistical results using the Kruskal-Wallis Test showed the difference of the use of sucrose 2 and 6 gr in the media on thePenicillium spp colonies number. Colony morphology showed better performance at 5 gr of tofu waste mass. Morphological analysis shows the differences in morphological characters which are quite far from commercial media as a control using PDA. As conclusion, tofu waste media can be used to growPenicillium spp, but it is necessary to add some components both in the form of elements and compounds to tofu waste media to be able to display results that can approach commercial media.

The result showed that the average of total consumption of tofu by underprivilage families was 2,017.50 grams/week or 288.21 grams/day, while for tempe was 1,296.50 grams/week or 185.21 grams/day. Underprivilage families ate tofu and tempe very often. Consumption purposes of tofu and tempe was for pleasure and habit in which processing use deep frying and being sauteed. Underprivilage families consumpted tofu and tempe by buying. Factors that affected on tofu consumption by underprivilage families were tofu price, chicken egg price, and number of family members; while factors that affected on tempe consumption by underprivilage families were salted fish price, chicken egg price, family income and the number of family members.Key words: consumption pattern, tempe, tofu, underprivilage families

Literature studies show that the nutrient content in tofu pulp is still high; however the utilization of this waste is still relatively low by the community. Nowadays, tofu dregs is still widely used as an ingredient for animal feed. Some of the reasons why people don't take advantage of tofu waste are consits of the funding, equipment, time and worries related to starting their own business. The aims of this study is to make a pre-designed tofu dregs processing plant into a multipurpose product aggregate such as sausages driven by the tofu business community. The method stage in this research is making a feasible product and process scheme, analyzing tofu solid waste in the form of a paper project and making a household scale sausage production prototype. The results of this study are able to produce a role model for tofu dregs utilization which is more conomically valuable but still meet the standard and quality of reasonableness. The results of the role model will be disseminated by reaching out to tofu entrepreneur communities to collaborate with each other so that the utilization of tofu with high economic value can be carried out more massively, structurally and systematically.

Tofu is one type of food made from the soybean. Protein content and high water content make tofu easily damaged. Solving this problem is needed the right way to be able to maintain the quality of knowing physically, so that can be stored for a long time without experiencing quality changes and can be accepted and safe for consumers. The purpose of this study was to determine the optimal temperature and storage time of tofu to maintain the quality of tofu in according to the quality requirements of knowing in SNI by looking at the physical changes that have been known during the shelf life. This type of study is a descriptive study to determine the organoleptic properties of tofu which include odor, taste, color, and appereance of tofu during the storage period with the help of panelist of three people. Observation data were analyzed descriptively using tables and explained in narrative form. Tofu samples were taken from three factories in Kupang Regency. The results showed that the ideal of tofu storage temperature was at 40C with a storage time of up to 6 days. The seller and factory owner they should pay attention to the storage temperature and sanitation, so that the tofu sold can survive without reducing the value of quality and taste from tofu.

Symbiont bacteria from mangrove litter are known to have antimicrobial activity against Staphylococcus aureus. However, only a handful of research has been carried out on microbes as an innovative natural material for preserving food, especially tofu. This research used four species of mangrove litter symbiont microbe, which were cultured as a microbial consortium. The study aimed to determine the potential of consortium microbe as tofu preservatives. The tofu was soaked in the liquid culture of the consortium microbe as a treatment, while for the positive control, it was immersed in tofu using 37% formalin, and for the negative control, the tofu was not given any treatment. The organoleptic observations on the second day showed that the tofu with all treatment did not change in odor, color, and texture. On the other hand, tofu without treatment became more acidic in odor, with a yellowish color, and showed a softer texture. On the third day, tofu with bacterial microbe treatment had a slight change in odor, the color became yellowish, and the texture was slightly softened. Tofu with formalin treatment did not change in color, but became more solid and extruded formalin odor. Tofu with the consortium microbe immersion treatment had the least amount (6.795x103) of total microbe count, compared with the formalin treatment (9.766x103) and without treatment (9.766x103).
