Abstract
The invention discloses a kind of extracting method of natural red colouring matter.It is that to adopt high grain or high grain shell be raw material, and liquid → filtration → evaporation concentration → steps such as purification are easy, cheap, extract to high-quality natural red colouring matter through purifying and dedusting → poach → get.This method is suitable for industrial mass production for fully utilizing high grain and high grain shell provides a kind of new approach.
Description
The present invention be a kind of be the method that raw material extracts natural red colouring matter with high grain or high grain shell.
As everyone knows, food dye has purposes very widely in foodstuffs industry.Its color is three kinds of basic primary colors with red, yellow, indigo, and people can be mixed with versicolor food color with these three kinds of primary colors as required according to a certain percentage.Wherein red pigments is a color pigments the most commonly used in food, the beverage.
At present, the haematochrome that uses in foodstuffs industry has only amaranth and two kinds of famille roses.(its molecular formula is respectively the derivative that these two kinds of haematochrome all are the benzene of synthetic
Therefore, use not only cost height of this synthetic haematochrome, and usage quantity can make too much the people produce the dominance poisoning.Show that through check edible for a long time this class synthetic colour can be carcinogenic.
It is the method that raw material extracts natural red colouring matter with high grain or high grain shell that purpose of the present invention aims to provide a kind of.According to said method can from high grain or high grain shell, extract natural red colouring matter at an easy rate, can avoid containing in the synthetic colour toxic shortcoming again.
The present invention extracts haematochrome from high grain or high grain shell flow process is: purifying and dedusting → poach → get liquid → filtration → evaporation concentration → purification.
The specific implementation method of above-mentioned flow process is: high grain or high grain shell are selected clean impurity, wash dedusting with water and drop in the extractor by 8: 1 water material weight ratio and carry out poach, poach time when grain (drop into material be high) is that (with the broken Pi Weidu of high grain) or the poach time about 40 minutes when grain shell (drop into material be high) is 60 minutes.The red liquid that poach produces carries out evaporation concentration after separating, filtering.Look liquid measure after the evaporation concentration is 1/4th of a charging capacity.With concentration is that 95% ethanol joins in this concentrated red liquid, makes that alcoholic acid content is about 60% in look liquid this moment.Left standstill 8～12 hours.Use Plate Filtration.Place vacuum concentration equipment to reclaim ethanol filtrate at last, repeat to be recovered in the filtrate always and do not contain till the ethanol.At this moment the red liquid that obtains is the liquid natural red colouring matter.If proceed evaporation, drying.Also can obtain natural red colouring matter dry powder.
High grain in traditional Chinese medical science medical book, put down in writing useful in sharp gas, puckery stomach, end effects such as cholera, diarrhea and damp and hot dysuria, and its major ingredient P-hydroxyl almond fine-the glycoside major part all is contained in high grain epidermis and the high grain shell.Therefore, in food, beverage, use with high grain or high grain shell to be the natural red colouring matter that raw material extracts, not only can make food, beverage be rich in painted aesthetic feeling and promote appetite of people, but also have certain function of health care.
Because extracting the employed main raw material of natural red colouring matter with method of the present invention is high grain or high grain shell, and extracts the later high grain of haematochrome and still can be used to wine brewing, the while is not reduced the yield of liquor.Therefore, this method is for fully utilizing high grain and high grain shell provides a kind of new approach.
Example: with 100 kilograms high grains or high grain shell is raw material, after selecting clean impurity, washing dedusting with water, adds 800 kilograms water in proportion, drops in the extractor and carries out poach.Want poach 40 minutes when dropping into when raw material is high grain, and when the input raw material is high grain shell, wanted poach 60 minutes.The red liquid that poach produced is separated from extractor.After look liquid filters with silk, put into vacuum-evaporation appts or atmospheric evaporation equipment carries out evaporation concentration, be concentrated to the look liquid measure always and be till 25 kilograms (drop into when being poach high grain in the extractor or high grain shell amount 1/4th).Add 43 kilograms of concentration then and be 95% ethanol, make that alcoholic acid content is about 60% in look liquid this moment.Left standstill 8～12 hours.Use Plate Filtration.Place vacuum concentration equipment to reclaim ethanol filtrate at last, repeat to be recovered in the filtrate always and do not contain till the ethanol.At this moment we just can obtain about 27 kilograms liquid natural red colouring matter.If proceed evaporation, make it become fluid extract, then fluid extract is placed the dish device, put into the vacuum drying oven inner drying, promptly get natural red colouring matter dry powder.
Claims (4)
1, the present invention is a kind of extracting method of natural red colouring matter, it is characterized in that this natural red colouring matter is is raw material with high grain or high grain shell, through purifying and dedusting → poach → get liquid → filtration → evaporation concentration → purification to make.
2, method according to claim 1, it is characterized in that the water material weight ratio that high grain or high grain shell drop into when poach is 8: 1, poach time when grain (drop into material be high) is that (with the broken Pi Weidu of high grain) or the poach time about 40 minutes when grain shell (drop into material be high) is 60 minutes.
3, method according to claim 1 is characterized in that the red liquid measure after the evaporation concentration is 1/4th of a charging capacity.
4, according to claim 1 or 3 described methods, it is characterized in that the process that red liquid after the evaporation concentration is purified to haematochrome is: in look liquid, add concentration and be 95% ethanol, make that alcoholic acid content is 60% in the look liquid, left standstill 8～12 hours, Plate Filtration, place vacuum concentration equipment to reclaim ethanol filtrate, repeat to be recovered in the filtrate always and do not contain till the ethanol.
