Method for extracting anthocyanin from lunar incense fructification

Abstract

The present invention relates to a method for extracting anthocyanin from yin-fragrant fruit, including the following steps: (1) to put the yin-fragrant fruit in a vessel, adding water until submerging the fruit, to heat until boil and take out, to cool until room temperature, to beat so as to make the sarcocarp and fruit stone to separate; (2) to add the yin-fragrant fruit and the fruit stone into alcohol solution, and to regulate the pH value of the mixing liquid, dipping beating, filtering and collecting filtering liquid; (3) to decompress and distill the filtrate so as to recover alcohol solvent, to make the alcohol chroma of the filtrate decrease until 10 percent, then to fetch clear liquid after placing whisht, to obtain yin-fragrant anthocyanin extracting liquid; (4) to absorb and separate the yin-fragrant anthocyanin extracting liquid with big-holes adsorption resin, to wash with alcohol solution, at the same time to collect washing liquid to decompress and dry, to produce powder shape yin-fragrant fruit anthocyanin. The yin-fragrant anthocyanin pigment has high stability, stable anti-oxidation activity and simple technics as well as raw material has low cost.

Description

technical field [0001] The invention relates to a food additive, in particular to a method for extracting anthocyanins from yin xiang fruit. Background technique [0002] Food coloring is an indispensable additive in food, medicine, cosmetics and other industries. Existing food pigments are divided into two categories: synthetic pigments and natural pigments. The use of synthetic pigments seriously affects the safety of food. There have been strict restrictions on the scope and dosage of its use as food additives in the world, and even countries such as Norway It is completely forbidden to be used in food, medicine, etc.; and the synthetic food pigments such as amaranth and carmine that are still allowed to be used in my country will generate carcinogenic β-naphthylamine and α-amino-1-naphthol during metabolism in the human body . Natural pigments originate from nature, are easy to be decomposed in nature, do not accumulate in organisms, generally have no toxic and side effe...

Problems solved by technology

The extraction of existing plant pigments mostly uses fruits, vegetables, grains, etc. as raw materials, and the content of pigment substances in plants is low, so the extraction is difficult and requires a long time of extraction, reflux, enzyme treatment, etc., so the price of plant natural pigments expensive
