Review on the Extraction of Plant Gelatin-Carrageenan

Abstract:

Plant gelatin-carrageenan is a sulfated polysaccharide and is widely used in food and pharmaceutical industries, especially for capsule shells. The article reviewed the extraction of gelatin-carrageenan from marine plants with the emphasis on four key steps, including alkali pretreatment, acidified bleaching, extraction and dehydration. This would help in the future research and production of plant gelatin-carrageenan.
