Proteins serve as an imperative macronutrient in human nutrition and well-being. Their nutritional quality substantially varies with their digestibility, amino acid profile, bioavailability, processing and purity. From a nutritional viewpoint, the ideal integration of proteins from diverse plant sources can supply an adequate amount of essential amino acids to fulfil human health needs. The use of plant-derived proteins has recently gained momentum due to their multifaceted edible and nonedible applications and their biodegradable nature.
Fruits and vegetables are responsible for about 22% of food losses and wastes along the supply chain (not including the retail level). However, fruit and vegetable by-products (FVB) may be transformed into fibre-rich flours and bioactive compounds, mainly bound to the fibre, thus bringing value to the food industry due to health benefits and technological functionality. Therefore, these by-products have great potential to be applied in several food industries.
