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

Three distinct varieties of Sechium edule (dark green, light green, and white) were procured from the Vontovorona open-air market. The chayotes were thoroughly washed and peeled, and their peel, flesh, and seed, whether raw, boiled, or steamed were analyzed for their phytonutraceutical components. Each part was then dried in a dehydrator at 41°C for 48 hours, ground, and placed in sachets. Mineral micronutrient content was assessed using portable X-ray fluorescence equipment, revealing magnesium as the predominant element across all varieties. Specifically, magnesium content in the dark green variety ranged from 1.01% to 2.32%, in the light green variety from 1.13% to 2.32%, and in the white variety from 1.64% to 3.42%. Macronutrient analysis, performed via the Kjeldahl method, indicated moisture content variations in the dark green variety from 84.58% to 90.37%, in the light green variety from 72.87% to 91.74%, and in the white variety from 84.93% to 92.87%. Phytochemical screening identified the presence of flavonols specifically in the raw white variety.
