Abstract

The invention relates to a lycium barbarum pigment extract and a preparation method thereof. Lycium barbarum pigment obtained through cleaning, drying, crushing, extracting, centrifuging, ultrafiltration, purification and concentration has various physiological functions of resisting oxidation, regulating blood fat, protecting vascular endothelial cells, delaying aging, preventing fatigue, enhancing immunity, preventing tumors and the like. Meanwhile, the preparation method of the lycium barbarum pigment extract has the characteristics of being simple in process, easy to operate, relatively high in yield, favorable in quality and environment-friendly.

Description

technical field [0001] The invention relates to the field of plant extracts, in particular to a method for extracting wolfberry pigment which has various physiological functions such as anti-oxidation, regulating blood lipid, protecting vascular endothelial cells, delaying aging, anti-fatigue, enhancing immune function and anti-tumor. Background technique [0002] At present, food safety issues at home and abroad are paying more and more attention to returning to nature, and advocating green has become a development trend. The development of safe, non-toxic, stable, and health-care natural plant pigments has become a development direction of the food industry in recent years. Synthetic pigments will gradually Replaced by natural coloring. Most of the natural pigments come from plants, minerals, animals and microorganisms, among which plants are the main ones. [0003] Lycium barbarum (FructoLxcii) was first recorded in "Shen Nong's Materia Medica", which is the dry and matu...
