Background

Pectin is widely present in fruits and vegetables and is an important component of the plant intercellular substance. Pectin is a completely nontoxic natural food additive, is widely used in food industry, is mainly used as a gelling agent, a stabilizing agent, an emulsifying agent and a thickening agent, can remarkably improve the quality of food, is used for manufacturing jam, jelly, yoghourt, ice cream and the like, and can also be used for keeping fruits fresh. Pectin can also be used in the field of medicine and is an important pharmaceutic adjuvant. The pectin has certain curative effect on chronic diseases such as hypertension, hyperlipemia, etc., and also has cancer preventing and anticancer effects. There are data showing that pectin can also affect the absorption capacity of the small intestine to food.

Worldwide annual demand for pectin is now over 16000t and rises at a rate of around 5% per year. The current pectin production method is as follows: the pectin is obtained by crushing, extracting, filtering, concentrating, precipitating, washing, drying, and pulverizing the residue to obtain yellow or white powder. The pectin material is obtained from a wide variety of sources, and can be extracted from apple, citrus and orange peel residues, sunflower tray and stalk, beet residue, watermelon peel, papaya, pumpkin and sea buckthorn.
