In the last years, massive consumption of animal proteins became unsustainable for environment: for this reason it is useful to find a better use of vegetable sources and improve supply, to reduce meat consumption. Nowadays plant sources with high protein content and an excellent aminoacidic composition compared to animal sources, such as soybean, hempseed, lupinseed, microalgae are rediscovering.
Besides nutritional value, vegetable proteins result especially interesting as biologically active peptides source: they possess scientific proved antioxidant, antihypertensive, hypocholesterolemic and antitumoral effect. The knowledge of this bioactive molecule are economically important as they could be extracted.
