Abstract

In order to promote the nourishment of carp in farming, four foods have been created from traditional raw materials and containing different quantities of locally produced banana flour 3%, 6%, 10%. We tested these foods which contain 36% crude proteins and 8% lipids on carp fry with an initial weight of 9g. After 50 days of experiment, the final weights of the fish fluctuated between 121.53g and 122.45g depending on the treatments used. The food containing 10% banana flour and the control food showed the highest growth and food transformation rates, with specific growth rates (SGR) of 5.18%/d and 5.14% /d as well as a conversion rate of 1.17 and 1.15 while the food with 6% banana flour obtained a SGR of 5.15 and a conversion index (CI) of 1.15 while that the food with 3% obtained a SGR of 5.14 and a CI of 1.16. Thanks to this test, we were able to observe the impact of bananas on the premature development of tilapia. We will continue to study the use of local agri-food by-products and waste in feeding this fish.

Abstract

This study explores the viability of watermelon (Citrullus lanatus) and pumpkin (Cucurbita pepo subsp. Pepo) as unconventional sources for sustainable winemaking, contributing to a zero-waste circular economy in viticulture. The research employs a multidimensional methodology encompassing chemical analyses, sensory evaluations, and environmental impact assessments to scrutinize the entire lifecycle of wine production. The findings reveal watermelon wine's superiority, boasting a 14° alcohol content, while pumpkin wine ranges at 11°. Both wines maintain physico-chemical and organoleptic attributes, with minimal alterations in micronutrient content. The compost generated from processing waste contains essential nutrients for plant growth. Comparative analysis underscores the advantageous nature of this compost, laying the foundation for sustainable winemaking practices in Madagascar and illuminating the untapped potential of tropical fruits in the global viticultural landscape. This study, pioneering the valorization of unconventional fruit and vegetable in Madagascar, strives to contribute to the discourse on environmentally conscious winemaking, fostering a paradigm shift toward ecologically harmonious practices in the agro-industrial sector.

Abstract

To promote the nutrition of tilapia in farming, four foods were created using traditional raw materials and containing different quantities of locally produced banana flour. These foods, which contain 36% crude proteins and 8% lipids, were tested on tilapia fry with an initial weight of 8 grams. After 50 days of the experiment, the final weights of the fish fluctuated between 33.28 grams and 41.4 grams, depending on the treatments used. Foods containing 3% and 6% banana flour showed the highest growth and food conversion rates, with respective specific growth (SGR) rates of 3.98 and 3.62, as well as conversion rates (CI) of 1.8 and 1.69. Meanwhile, the food with 10% banana flour obtained a SGR of 2.92 and a CI of 2.01, while the control obtained a SGR of 3.3 and CI of 1.7. Thanks to this test, we were able to observe the impact of bananas on the premature development of tilapia. We will continue to study the use of local agri-food byproducts and waste in feeding this fish.

Abstract

This study meticulously investigates the chemical and nutritional profiles of two underexplored tropical fruit species indigenous to Madagascar: the Ceylon Gooseberry (Dovyalis hebecarpa) and the Cape Gooseberry (Physalis peruviana). Characterizing such native species is vital for diversifying food sources and enhancing nutritional security, particularly in biodiversity-rich regions.Systematic analyses performed across various plant compartments, notably their foliage, revealed a significant richness in essential micronutrients. Leaves of both species demonstrated substantial concentrations of potassium, phosphorus, iron, magnesium, and aluminum. Furthermore, Physalis peruviana leaves exhibited a particularly significant protein content, elevating their prospective utility beyond fruit consumption. This robust nutritional profile reinforces their potential as valuable, locally sourced ingredients to foster balanced diets in the region. Parallel to the nutritional assessment, empirical processing trials were initiated to ascertain the technological feasibility and quality attributes of derived products, focusing on wine. The fermentation processes consistently yielded wines categorized as dessert wines, which demonstrated stable physicochemical characteristics and promising shelf-life properties. This intrinsic stability, coupled with their unique profiles, suggests compelling added value within agro-food valorization strategies. Collectively, these findings underscore the considerable potential of both Dovyalis hebecarpa and Physalis peruviana for the innovative development of novel food products. Such initiatives not only contribute to agricultural diversification but also align seamlessly with circular economy principles by utilizing underexploited plant parts, and sustainable development by fostering local biodiversity and resource efficiency. This research provides a scientific basis for promoting the cultivation and processing of these indigenous fruits, contributing to economic growth and environmental stewardship.
