Abstract
This invention is extraction method of high-quality pectine from pomace with drying, squashing, acid hydrolysis, fileration, condensation, precipitation and disintegration. It is characterized as followings: we add the enzymolysis before acid hydrolysis and precipitation. Exactly speaking, we adjust pectine liquor'PH value to 3.2-3.8 for enzymolysis of starchlick materials. The enzymolysis agent could be fungus amylase, fruit juice amylase, glycosyl-transferase or mixed agent above. This invention is advantageous in reasonable process, simplified-manipulation, and easy-industralized. The method we used here to degenerate starchlike materials provides a new way for high-quality pectine industralizaion.
Description
(1) technical field
The present invention relates to a kind of method of producing pectin, particularly a kind of method of utilizing apple residue to produce high purity pectin.
(2) background technology
Pectin is a kind of line style natural high moleculer eompound that extracts from plant tissue, is widely used in industries such as food, medicine, makeup, and is especially unrestricted as its dosage of food service industry additive.Along with the develop rapidly of food service industry, the expense of pectin continues to increase.Domestic pectin production is started late, and most of pectin is from external import.The pectin resource of China is very abundant, all contains abundant pectin in citrous fruit peel, the apple residue, for example in the apple residue content of pectin with regard to 15%-20%.The commercial production raw material of China's pectin is based on citrous fruit peel at present, and the abundant apple residue of pectin content is not fully used as the byproduct of apple deep processing, major cause is to utilize residual more starchy material in the pectin that the hydrolysis of apple residue acid solution produces, make pectin purity low, influence it and apply on a large scale and suitability for industrialized production.
(3) summary of the invention
The purpose of this invention is to provide a kind of method of utilizing apple residue to produce high purity pectin, for a new way has been opened up in the extensive utilization of apple residue.
Technical scheme of the present invention:
