Comparative study on the composition and functional properties of chitin/chitosan extracted by new combined bioprocess.
Bio-extraction of chitin is a greener and eco-friendly process than the conventional chemical method. Taking shrimp waste of Pandalus borealis recovered from plant as a model, two methods were applied for chitin extraction; a chemical and a yeast-based processes (Ch-C and Ch-B respectively). The rec...
