Abstract
The invention discloses an extraction process of a grape skin pigment. The extraction process comprises the steps of: drying; crushing; extraction; concentration and drying; and purification. The extraction process provided by the invention is characterized by simple extraction technology, low requirements for production equipment, high extraction efficiency and short extraction time, and is superior to traditional technologies. The extracted red pigment is natural and pure green, has stable character and pure color, can be widely used in food processing and other industries, and is of far-reaching significance for improving the food safety of people.
Description
Technical field
The invention belongs to the extractive technique field of natural pigment, be specifically related to a kind of extraction process and application thereof of grape skin color.
Background technology
Food dye is indispensable additive in foodstuffs industry.Food dye comprises synthetic colour and natural pigment two kinds.Synthetic colour is with low cost, bright in colour, strong coloring force, stable to light, heat, oxygen and pH, but it has a large shortcoming, namely has toxicity, comprises toxicity, causes rushing down property and carinogenicity.These toxicity come from arsenic, lead, copper, phenol, aniline, ether, muriate and vitriol in synthetic colour, and they all can cause harm in various degree to human body.Natural pigment major part is taken from plant, and part takes from animal and mineral.The appearance of natural pigment, natural pigment exhibition direction.Plant, part takes from animal and mineral.Eliminating the poisonous chemosynthesis pigment of major part gradually.At present, " natural, nutrition, multi-functional " has become the developing direction of natural pigment.
Containing abundant anthocyanogen composition in Pericarpium Vitis viniferae, it is not only bright in colour, dye excellent, also having and improve liver, defence health peroxidation, prevent arteriosclerosis and improve the physiological functions such as eyesight, is a kind of important natural food colour and desirable foodstuff additive.
Summary of the invention
The object of the present invention is to provide a kind of extraction process and application thereof of grape skin color, provide a kind of plant pigments, foodstuff additive of natural, pure green, and preparation technology is simple, extraction yield is high.
The technical scheme of the extraction process of a kind of grape skin color of the present invention is achieved in that
An extraction process for grape skin color, is realized by following steps:
(1) dry: Pericarpium Vitis viniferae to be dried to constant weight under the vacuum condition of 30 ~ 60 DEG C, puts in moisture eliminator for subsequent use;
(2) broken: dried Pericarpium Vitis viniferae to be put into crusher and pulverizes, then cross 80 ~ 120 mesh sieves;
(3) lixiviate: added by extraction agent in the Pericarpium Vitis viniferae after fragmentation, lixiviate 55 ~ 85min, then filters;
(4) concentrate drying: concentrated by filtrate carrying out and reclaim extraction agent, obtains pigment meal after drying;
(5) purifying: adopt silica gel column chromatography to carry out separation and purification to extracted pigment.
The pH value also adding citric acid regulating solution in step (3) is 3.
The proportion of Pericarpium Vitis viniferae and extraction agent described in step (3) is 1:7 (g/mL).
In step (3), Extracting temperature is 68 ~ 72 DEG C, and the time is 68 ~ 72min.
Step (3) described extraction agent is ethanol.
Step (3) lixiviate is carried out in a water bath.
In addition, described grape skin color can be used as the application of foodstuff additive, food color or healthcare products.
Compared with prior art, the present invention has the following advantages:: raw material of the present invention extracts natural red colouring matter from a large amount of discarded grape skin, turns waste into wealth; Extraction process of the present invention is simple, and require low to production unit, extraction efficiency is high, and extraction time is short, is obviously better than conventional art; Natural, the pure green of haematochrome that the present invention extracts, and proterties is stablized, pure color, can be widely used in the industries such as food-processing, for the food safety improving people, has far reaching significance.
