production et utilisation de la poudre de fruits de citrouille (cucurbita maxima) pour la nutrition humaine et valorisation des feuilles en agriculture durable et protection de l'envirenement

Abstract

This study focuses on the production of pumpkin powder (Cucurbita spp.) using modern technology while highlighting its nutritional, economic, and environmental significance in Algeria. The findings revealed that pumpkin powder has high nutritional value due to its richness in dietary fibers, vitamins, minerals, and antioxidant compounds, making it a promising ingredient for various food industries. The study also demonstrated that the drying method used can produce high-quality powder while preserving the nutritional properties of the product and reducing post-harvest losses. From an economic point of view, this project contributes to the valorization of local agricultural products and helps reduce the costs associated with importing certain raw materials used in food processing industries. It also encourages investment and job creation in the agro-food sector. In addition, the study highlights the importance of reusing by-products generated during processing, which can be incorporated into livestock and poultry feed, while leaves and organic residues may be utilized as natural fertilizers to improve soil fertility. Therefore, this project supports the principles of sustainable development through waste reduction, environmental protection, and the promotion of a circular economy.
