Cactus pear (Opuntia ficus-indica) productivity, proximal composition and soil parameters as affected by planting time and agronomic management in a …
2021
Study of appropriate planting time and response to agronomic management practices is imperative for the newly introduced cactus pear (Opuntia ficus-indica (L.) Mill.) into a semi-arid region of India. Responses of cactus pear to agronomic practices (planting time and irrigation and fertilizer application) were evaluated to determine the potential for fodder production and livestock feed in a semi-arid environment of India. We assessed four planting times (February, March, July and October) and two agronomic managements (with and without irrigation and fertilizer application) during 2016–2020 at Jhansi, India. Cactus pear establishment and growth improved with planting time in July and Octob…
Kinetics of solid-state fermentation of lupin with Rhizophus oligosporus based on nitrogen compounds balance
2021
Solid-state fermentation could be a potentially effective method for improving the nutritional value of legumes. The objective of this study was to explore this technology in Lupinus mutabilis, a species of lupin, using a strain of Rhizopus oligosporus mold for solid-state fermentation. Three L. mutabilis varieties (INIAP-450, INIAP-451, and Criollo) were evaluated, including the effect of the grain status (whole or ground) and integument or husk (presence or absence). Kinetic parameters of the fermentation process were studied to define the specific speed of nitrogen formation and the digestibility and nutritional quality of the resulting protein. After incubation at 28 °C for 96 h, the ti…
Guidance on allergenicity assessment of genetically modified plants
2017
Abstract This document provides supplementary guidance on specific topics for the allergenicity risk assessment of genetically modified plants. In particular, it supplements general recommendations outlined in previous EFSA GMO Panel guidelines and Implementing Regulation (EU) No 503/2013. The topics addressed are non‐IgE‐mediated adverse immune reactions to foods, in vitro protein digestibility tests and endogenous allergenicity. New scientific and regulatory developments regarding these three topics are described in this document. Considerations on the practical implementation of those developments in the risk assessment of genetically modified plants are discussed and recommended, where …

Ligninolytic potential of Curvularia kusanoi L7 laccases for animal production
2020
The present research was conducted with the objective of evaluating the ligninolytic potential of Curvularia kusanoi L7 laccases in improving the nutritional quality of fibrous substrates for animal feed. Laccase production was obtained from C. kusanoi L7 under native conditions by solid submerged fermentation of wheat bran and by biological interactions with Trichoderma viride M5-2 and Trichoderma pleuroticola. The enzymes were purified from the culture broths by triphasic partition. The degradative potential of native and induced laccases where evaluated by determining foliar lignololytic capacity, raw wheat (Triticum aestivum) straw delignification and the effect of enzyme pretreatment o…
Formulation et procédés de fabrication des gels laitiers enrichis en globulines de fèverole :Impact sur la rétention protéique chez les rats jeunes e…
2017
Introduction et but de l’étude : L’impact environnemental et les risques pour la santé associés à la production et la consommation excessive de sources de protéines animales pourraient être limités par l’augmentation de la part des protéines végétales dans notre alimentation. Les protéines végétales sont parfois déficitaires en certains acides aminés (AA) essentiels. De ce fait, un mélange de protéines animales et végétales permettrait d’assurer une complémentarité en AA répondant aux besoins de l’organisme. L'objectif de cette étude était d'évaluer l'impact, sur la taille des protéines, de la formulation et des processus de transformation des gels laitiers enrichis en légumineuses et d’étu…
Feeding Dairy Ewes with Fresh or Dehydrated Sulla (Sulla coronarium L.) Forage. 1. Effects on Feed Utilization, Milk Production, and Oxidative Status
2022
Feeding dairy ewes with fresh sulla forage (FSF), a legume species containing condensed tannins (CT), has been shown to increase feed intake, milk yield, and casein and enhances the oxidative status of animals. Dehydration of FSF could be an alternative to hay-making to preserve the nutritional properties. This research aimed to compare the responses of dairy ewes fed with diets based on sulla hay (SH), pelleted dehydrated sulla forage (DSF), or FSF in terms of efficiency of feed utilization, milk production, and the balance between oxidant (reactive oxygen metabolites (ROMs)) and antioxidant (biological antioxidant potential (BAP)) substances at the plasma level. Ten first-lambing (FL) and…
Effect of Innovative Food Processing Technologies on the Physicochemical and Nutritional Properties and Quality of Non-Dairy Plant-Based Beverages
2020
Increase in allergenicity towards cow’s milk, lactose intolerance, the prevalence of hypercholesterolemia, and flexitarian choice of food consumption have increased the market for cow’s milk alternatives. Non-dairy plant-based beverages are useful alternatives because of the presence of bioactive components with health-promoting properties, which attract health-conscious consumers. However, the reduced nutritional value and sensory acceptability of the plant-based beverages (such as flavor, taste, and solubility) compared to cow’s milk pose a big threat to its place in the market. Thermal treatments are commonly used to ensure the quality of plant-based beverages during storage. However, th…
In vitro digestion of two age-tailored dairy products in the aging gastrointestinal tract
2023
For older adults (> 65 years old), undernutrition is a severe health problem that can impact the quality of life, induce or aggravate the development of diseases, and reduce life expectancy. Undernutrition can be defined as an inadequate intake of dietary energy and proteins combined with a low muscle mass. Diet-induced muscle mass and strength loss in older adults may be due to insufficient protein intake. Therefore, older adults need to increase the amount of high-quality ingested proteins, particularly foods rich in leucine, to promote muscle health. However, it is still unclear if changes in protein digestibility and absorption kinetics in old age may affect the anabolic effect of high-…
Moringa oleifera supplemented foods in South Africa : A multidisciplinary approach combining consumer studies with physico-chemical and nutritional a…
2021
Malnutrition is a major challenge in South Africa (SA), particularly in Eastern Cape and Limpopo provinces, which are predominantly black and historically disadvantaged. This thesis aims to assess the potential of Moringa oleifera (MO) as a source of nutritional improvement in the diets of mothers and their children in these provinces. Known for its nutritional benefits, MO is a plant native to India, now cultivated in SA but not widely used for human nutrition. A two-part approach was followed in this thesis. The first part aims to understand how MO is perceived by consumers and how it can be integrated into the South African food repertory. A study of the knowledge, beliefs and consumptio…
