The content of polysaccharides obtained by different methods listed in the order of cellulase extracts > pectinase extracts > compound enzymes extracts > papain extracts > hot water extracts and was 45.43%, 44.08%, 43.17%, 42.84% and 42.55%,respectively (Table 1). Protein content determination revealed the papain extracts contained the lowest protein content, indi-cating the proteins were likely degraded into polypeptides by papain
