The production of galacturonic acid enriched fractions and their functionality
Vegetable tissues discarded at harvesting or after industrial processing constitute a valuable and renewable source of biopolymers and bioactive compounds. Upgrading of vegetable waste can not only reduce pollution but also add value to the commodity production. Plant cell walls are an important sou...
