Abstract

The invention provides a preparation process and application of micromolecular pectin, and relates to the field of pectin processing and production. The preparation process of the micromolecular pectin mainly comprises the steps of enzymolysis treatment, crushing and grinding, acidolysis treatment, filtration treatment, pH adjustment, ultrafiltration and alcohol precipitation and the like, and the application of the micromolecular pectin mainly comprises the application in formaldehyde absorption and cat litter preparation. The defects in the prior art are overcome, acid-base treatment and filtering treatment are adopted, and the micromolecular pectin is obtained and has good application value in the aspects of cat litter preparation and formaldehyde removal.

Description

technical field [0001] The invention relates to the field of pectin processing and production, in particular to a preparation process and application of small molecule pectin. Background technique [0002] The full name of small molecular pectin is modified citrus pectin, also known as low molecular citrus pectin. It is a polysaccharide compound with galactose as the main component extracted from the peel and pulp of citrus, lemon, orange and pomelo. Anti-tumor, anti-aging, anti-virus, anti-inflammation, anti-ulcer, hypoglycemic, hypolipidemic, anticoagulant, and improving immune function and other pharmacological effects have attracted more and more attention. Most of the existing pectin extraction methods It is to extract macromolecular pectin, but it is more difficult to extract small molecular pectin. Nowadays, macromolecular pectin is used to undergo high temperature and high pressure intelligent cutting process, or acid and alkali treatment is used to obtain small mole...
