Abstract

The invention provides a method for preparing a lily polysaccharide microcapsule. The method for preparing the lily polysaccharide microcapsule comprises the following main steps: first dissolving gelatin and arabic gum separately, then performing uniform mixing, adding lily polysaccharide into the mixed solution, performing high-speed dispersion for 3 min under 100 r / min, adjusting pH to be acidity with 10% glacial acetic acid and then continuing to stir for a certain period of time and then performing taking-out, performing cooling to about 10 DEG C in an ice-water bath, adjusting pH to 6.0with 10% sodium hydroxide, adding transglutaminase (TGase), continuing to stir and solidify, performing standing and vacuum filtration to obtain a wet capsule product, spreading the microcapsule wet capsule flat in a petri dish, performing pre-cooling at -20 DEG C for 24 h, and then performing freeze-drying under 1 Pa pressure vacuum conditions for a time not less than 24 h to obtain the solid microcapsule. The microcapsule can slowly release the lily polysaccharide, prolongs the action time, improves the utilization efficiency of the lily polysaccharide, and realizes the wider application ofthe lily polysaccharide in the fields of food and medicine.

Description

technical field [0001] The invention relates to a preparation method of lily polysaccharide microcapsules, belonging to the technical field of food processing. Background technique [0002] Lily is a kind of traditional Chinese medicine with the same origin of medicine and food. It is rich in resources and widely distributed in our country. It has the effects of nourishing yin, nourishing the lungs, relieving cough, clearing the heart and calming the nerves. It is clinically used to treat dry-heat cough, bloody sputum, deficiency, troubles and palpitations, insomnia, dreaminess, and trance. In recent years, it has been found that it has a wealth of pharmacological activities, especially showing significant inhibitory effects on tumors and depression, but there are few related products developed by it. [0003] Lily polysaccharide is extracted from lily, which is rich in lily bulb and is one of the main active ingredients of lily. Lily polysaccharide has a variety of pharma...
