Texto completoThis thesis proposes the use of instrumental measures of the texture of food vegetables to improve their cooking processes. The first part points out that the texture is linked to human perception. The sensory analysis is so the direct way of its assessment. Main instrumental tests are then presented and experimental protocols are described. Each of the following three chapters deals with an application of the instrumental measure of the texture for a better knowledge of the products quality. The first objective consists in identifying the kinetics of textural modification of vegetables within sterilization temperatures. Using models of the literature, our results al verifying that a simple first order kinetic is not enough to characterize the evolution of texture of canots or French beans. It is then interesting to assimilate the final phase of texture cooking to a plateau. The fractional conversion model used leads to a satisfactory description. The identified parameters of the model are useful to optimise heating processes. Instrumental measures are applied as a time-temperature integrator in a pressure cooker. At constant textural cooking, the effects of the process parameters are evaluated on the keeping back of vitamin. The characterization of the texture allowed improving this way of preparation of vegetables by reducing significant nutritional losses. The last chapter proposes a method to estimate the presence of strings in French beans. The comparison of two instrumental measures on the same piece of vegetable leads to predict a stringy character of the beans

Texto completoThis work focuses on the study of the PEF pretreatment effect of plant tissue on the freezing process. For that purpose, a study of the mechanisms occurring during the plant tissue permeabilization by PEF was performed. Results show that cells treated in a perpendicular direction to the electric field lines are more readily permeabilized than those treated in the direction parallel to the fields. There is no direct relationship between the effectiveness of CEP treatment and the cell radius. The ratio of the electrical conductivity of the tissue before and after treatment plays an important role in the choice of the PEF treatment parameters. Results have shown that the effect produced by a PEF pretreatment on the osmotic dehydration (OD), the freeze-drying and the freezing process show that a pretreatment at low intensity (400-580 V/cm) reduces the required freezing time. The results of the model developed showed that treatment with CEP seems to decrease their latent heat by changing their water content. Products treated with CEP + DO are frozen and freeze-dried faster than the untreated samples and with a better visual appearance

Texto completoScientific evidence on the benefits of plant-based diets (environmental, health and animal welfare) is growing. Yet, individual meat consumption remains high. The first part of this dissertation uses experimental economics methods to identify and remove some of the barriers that limit the transition towards plant-based diets. Chapter 1 presents an experimental approach to measure the social stigma associated with following a plant-based diet. The results do not conclude to the presence of vegephobia in the economic environment but underline the limits of the employed tools. Chapter 2 reports the results from an experiment on the impact of an information campaign about plant-based diets on a representative sample of French doctors. The information campaign has a positive impact on the doctors' views and, to a smaller extent, improves their practices. The second part of the dissertation is dedicated to reduce publication bias and questionable research practices in economics in order to reduce the likelihood of a replication crisis. Chapter 3 provides a practical guide to Registered Reports for economists. The guide describes the benefits of Registered Reports and details the necessary methodological components (analysis plan, power analysis, smallest effect size of interest, etc.). Specific examples for experimental economics as well as R and Stata codes are provided to facilitate the implementation of Registered Reports

Texto completoThe objective of this work was to evaluate the level of food contaminants, trace elements and pesticides residues, in four types of commodities bread, white cheese, vegetables and fruits, and drinking water considered as the most consumed by the Lebanese population based on the Food Basket Study on 2006. A multielemental method was optimized in terms of sensitivity and inference elimination by using high resolution sector field inductively coupled plasma mass spectrometry (HR ICP/MS) for the determination of 20 minor and trace elements in the selected foods to assess the nutritional contribution and the level of contamination. For pesticides residues analysis, an analytical method was developed for the quantification of residues in cheese (2-25% fat). Bread, vegetables and fruit were analysed according to the QuEChERS method. For the monitoring study, the samples were collected during two seasons, wet and dry, from five geographical regions in Lebanon

Texto completoBecause of the exponential growth of malnutrition pathologies particularly in South countries, the development of functional foods based on fermented cereals represents an alternative to dairy products already marketed. The incorporation, the stability of lipophilic bioactive compounds such as carotenoids and phytosterols, as well as their behavior during the gastro-duodenal digestion have to be studied, in order to demonstrate the nutritional potential of this new product. Indeed, it is known that phytosterols decrease the carotenoid bioavailability. The main objective of this work was to design a probiotic functional food based on maize and enriched with carotenoids and phytosterols, and study the stability, the bioaccessibility and the intestinal absorption of these fat-soluble compounds. The formulation and the standardization of the manufacturing process, including the selection of starters for fermentation in order to obtain a probiotic product, were developed. During the production, the stability of fat-soluble compounds showed a retention level of 73%. The effect on dispersible phytosterols on the β-cryptoxanthine, β-carotene and lycopene bioaccessibilities was evaluated thanks to an in vitro digestion model mimicking the gastric and duodenal conditions. The intestinal absorption of these compounds was also estimate by crossing the in vitro digestion model with a Caco-2 cells model (TC7). The study demonstrated that thanks to their vehicles, dispersible phytosterols provide a potential cholesterol-lowering effect to this food, without affecting the carotene bioaccessibility. In fine, this functional food was optimized in terms of sensory and nutritional levels, by using whey protein isolates

Texto completoIn the context of the exponential development of aquaculture, fish meal and oils, previously the main components of aquaculture feed, have been increasingly replaced by a blend of plant products. However, total replacement is not yet possible without impairing fish performance (survival and growth). To continue its sustainable development, aquaculture must further decrease its reliance on both fish oil and fish meal. In addition to the changes in diet composition, a possible way forward is the use of the genetic variability for the ability to survive and grow with plant-based diets (V diets) existing in trout populations. However, very few studies have investigated the mechanisms implemented by some genotypes to use these diets more efficiently. The objective of this thesis was to study the characteristics that led to a better utilisation of V diet in different rainbow trout genotypes. The originality of this PhD work relies on the genetic rainbow trout lines whose responses to a 100% V diet were studied by combining nutritional physiology and molecular biology with or without a priori approaches. Thus, the transcriptomes of three isogenic lines, which have contrasting performances when fed V diets, were compared at short and long term. Then nutrition-related traits, as well as the expression of some genes identified through the transcriptomics analysis, were studied in a line selected for its ability to survive and grow with a V diet. The results obtained led to the conclusion that the acceptance of V diets plays a key role, particularly in the early stages. The results also highlight the essential role of the immune system, which is impacted differently according to genotypes. Finally, after 6 months of feeding, while lipid metabolism seems to play a role in the differences between genotypes for their ability to efficiently utilize the V diet, this pathway does not appear to play a determinant role in the selected line. Overall, our results suggest that there are a wide variety of mechanisms allowing trout to survive and grow with a total plant-based diet, devoid of both fish meal and oils
