Abstract

The invention relates to a method for extracting haematochrome from mulberries and belongs to the field of a food additive and a preparation method therefor. The method for extracting haematochrome from mulberries comprises the following steps: (1) washing, crushing, freezing and drying fresh ripe natural mulberries to obtain frozen mulberry dry powder; (2) adding an organic solvent into tomato paste in a certain ratio of material to liquid, fully stirring the mixture and heating and extracting the mixture for a while, and filtering the mixture to obtain a filtrate; and (3) concentrating the filtrate at a reduced pressure and vacuum-drying the filtrate to obtain haematochrome of mulberries. The extraction method for the haematochrome of mulberries provided by the invention has the characteristics of being simple in process, strong in operability, suitable for industrial production, high in extraction recovery rate and the like.

Description

A kind of method extracting haematochrome from mulberry fruit
Technical field
The present invention relates to a kind of method extracting haematochrome from mulberry fruit, belong to foodstuff additive and preparation method thereof field.
Background technology
Mulberry fruit, having another name called mulberry jujube, Sang Shi, black mulberry, black mulberry etc., is the mature fruit cluster of perennial Moraceae deciduous tree mulberry tree (MorusalbaL).China's mulberry fruit resource is very abundant, and except Qinghai-Tibet Platean, all there is cultivation all parts of the country.Mulberry fruit not only flavour is delicious, and has many nourishing functions, and since ancient times, mulberry fruit is just as Application to the Chinese medical herbs, and the many famous TCM work of China such as Compendium of Material Medica, " Chinese medicine voluminous dictionary ", " Chinese medicinal herbal " etc. have the record of mulberry fruit people medicine.Traditional Chinese Medicine thinks that mulberry fruit taste is sweet, cold in nature, tool promotes the production of body fluid to quench thirst, liver-kidney tonifying, nourishing YIN and supplementing blood, improving eyesight are calmed the nerves, sharp joint, curing rheumatism, the effect such as to relieve the effect of alcohol.People have carried out many-sided research to the chemical composition of mulberry fruit, pharmacological action, active function in recent years, find the several functions composition such as amino acid, VITAMIN, mineral substance, flavones, alkaloid containing abundant needed by human in mulberry fruit, there is immunologic enhancement, hypoglycemic, reducing blood-fat, hypotensive, anti-inflammatory, the effect such as anti-ageing, antitumor.Mulberry fruit is bright in colour, is natural food pigment, has certain nutrition and health care effect.
Ripe mulberry fruit contains abundant haematochrome compound, it is a natural pigment, flavonoid compound in platymiscium chemistry element, epidemiology survey and experimental study confirm, mulberry red pigment has extensive, the excellent biological effect, particularly its anti-tumor activity such as anti-oxidant, anti-inflammatory, antitumor, atherosclerosis with natural, low toxicity, efficient and receive much concern.Therefore Isolation and purification mulberry very haematochrome, and study its pharmacologically active and dependent interaction mechanism, for the pharmacologically active essence and the further mulberry fruit resource that develops disclosing mulberry fruit, all there is certain meaning and value.
Summary of the invention
It is simple, workable that the present invention aims to provide a kind of technique, is applicable to the extracting method of suitability for industrialized production and the high mulberry haematochrome of extraction recovery.
A kind of method extracting haematochrome from mulberry fruit of the present invention, comprises the following steps:
(1) by natural for fresh mature mulberry fruit through washing, smashing, lyophilize, obtain freezing mulberry fruit dry powder; ;
(2) in mulberry fruit dry powder, add organic solvent by certain solid-liquid ratio, fully stir and heat lixiviate certain hour, filter and obtain filtrate;
(3) by filtrate reduced in volume and namely vacuum-drying obtain mulberry red pigment.
Preferably, the organic solvent in step of the present invention (2) be ethanol, ethylene glycol, glycerol or and composition thereof;
Preferred, the solid-liquid ratio in step of the present invention (2) is 1:5-6;
Preferred further, the Heating temperature in step of the present invention (2) is 45-65 DEG C;
Further preferred, the extraction time in step of the present invention (2) is 6-8h;
Further preferred, in preparation method of the present invention, suitably increase extracting times and stirring velocity can improve the extracted amount of mulberry red pigment.
A kind of method extracting haematochrome from mulberry fruit of the present invention, has technique simple, workable, is applicable to suitability for industrialized production and extraction recovery high.
