Abstract: The unconventional feed resources such as pomace, oilseed meal and bran are abundant in China, but the high non-starch polysaccharides content affects their application in animal production. The pectin component, which is as high as 20%, is not only poorly utilized but also affects the digestion and absorption of other nutrients, and is regarded as an anti-nutritional factor in feed of monogastric animals. In recent years, there have been more studies on the cellulose and hemicellulose components of non-starch polysaccharides, but little research has been reported on the biodegradation of pectin in feeds. This paper reviewed the structure, distribution and nutritional properties of pectin in feed and the progress of its microbial degradation in order to provide a new idea and method for reduction and substitution of corn and soybean meal.

Key words: pectin, pectinase, microorganism, biodegradation
