Abstract

The invention discloses an extraction method of fructus-clausenae-lanii-peel uranidin. The extraction method comprises the following steps: 1), taking fructus-clausenae-lanii peel, and washing cleanly and smashing the fructus-clausenae-lanii peel; 2), adding the smashed fructus-clausenae-lanii peel into distilled water for mixing, putting an obtained first mixture at a low temperature for refrigeration until the first mixture is completely frozen, afterwards, taking out the first mixture for thawing at a room temperature, and adding cellulase into the first mixture for enzymolysis, so as to obtain a fructus-clausenae-lanii-peel extracting solution; 3), centrifugally separating the fructus-clausenae-lanii-peel extracting solution to abandon a precipitated part impurity, so as to obtain a fructus-clausenae-lanii-peel uranidin crude extracting solution; 4), enabling the fructus-clausenae-lanii-peel uranidin crude extracting solution to pass through a 100nm to 200nm microfiltration membrane, so as to obtain primary effluent liquid; 5), enabling the primary effluent liquid to pass through an ultrafiltration membrane of which the cutoff molecular weight is 3KDa to 5KDa, so as to obtain final effluent liquid; 6), carrying out vacuum freeze drying on the final effluent liquid, so as to obtain the fructus-clausenae-lanii-peel uranidin. The method provided by the invention is simple; the uranidin obtained through extraction is brilliant yellow; particles are loose; the solubility is good.

Description

technical field [0001] The invention belongs to the technical field of pigment extraction, and in particular relates to a method for extracting yellow pigment from yellow peel. Background technique [0002] With the continuous deepening of medical, toxicology and biological experiment research, people are paying more and more attention to the harm of excessive use of synthetic pigments to human health, so the amount of synthetic pigments used as food additives is becoming more and more strict. Natural pigments are bright and attractive, full of natural feeling, especially some natural pigments are the ingredients of people's daily diet, and have certain nutritional value and pharmacological health care function. Among natural pigments, yellow hues are relatively soft and attractive compared with other hues, which can make consumers have a strong desire to buy. With the large demand in foreign markets, natural yellow pigments are in short supply. [0003] Common pigment extr...
