Abstract
The extraction process of pigment of vaccinium uliginosum is the extracting method that discloses a kind of natural food colour.It is that the employing DUSIGUO is a raw material, behind purifying and dedusting, press extracting juice and skin, skin through poach → get liquid → centrifugal → place back → water cooking liquid with the squeezing juice merging or respectively → filtration → macroporous resin adsorption post → 95% edible ethanol wash-out → get elutriant → reduction vaporization is concentrated → drying etc., step is easy, cheapness extracts to high-quality natural food colour.This method for the comprehensive utilization DUSIGUO particularly the DUSIGUO skin opened up a kind of new way, be applicable to industrial mass production.
Description
The present invention be a kind of be the method that raw material extracts natural pigment with the DUSIGUO.
As everyone knows, food dye is indispensable additive in the foodstuffs industry, along with science and technology development, and many once widely used synthetic colours, they have detrimentally affect to HUMAN HEALTH and are eliminated successively owing to discovery.Therefore studying new food dye, particularly natural pigment is subjected to extensive attention both domestic and external day by day, and many scientific workers just are being devoted to study inexpensive natural pigment to replace the synthetic colour of present use.
Once had human DUSIGUO juice to extract natural pigment, add alcohol in the fruit juice after, filter, after getting filtered solution and boiling off ethanol, liquid pigment, this pigment shortcoming of tongue, lip, skin of having illicit sexual relations, and be liquid makes troubles for the transportation preservation.
Raw materials usedly in present method can be the DUSIGUO skin, and this pericarp is used as refuse and discards in foodstuffs industry at present, so present method is that utilization of waste material DUSIGUO skin has been opened up a new way.
It is the method that raw material extracts natural pigment with the DUSIGUO that purpose of the present invention aims to provide a kind of.According to said method natural food colour can be from DUSIGUO, extracted at an easy rate, toxic shortcoming can be avoided containing in the synthetic colour again.
The present invention extracts natural pigment from DUSIGUO flow process is:
Clean →
→ concentrate → drying by macroporous resin adsorption post → 95% edible ethanol wash-out → get elutriant → reduction vaporization.
Above-mentioned flow process specific implementation method is: gets after DUSIGUO selects clean dedusting, and squeezing, pressure is 15-20kg/cm
2Get fruit juice and pericarp two portions.Get the pericarp boiling three times, each 30 minutes, the water yield that adds is: the water that decocts adding for the first time is five times of pericarp weight, for the second time, the water that decocts adding for the third time is respectively three times of pericarp weight, centrifugal behind the poach (2000-3000 rev/min), pass through the macroporous resin adsorption post after getting the supernatant liquor Plate Filtration, flow rate control is the 30-60ml/ branch, use 95% edible ethanol wash-out pillar then, access elutriant, reduction vaporization is concentrated, and (temperature: 50-60 ℃, pressure: 160-260mmHg) to nothing alcohol flavor, spraying drying (temperature: 50-60 ℃) promptly gets Powdered natural pigment.And the fruit juice part is directly passed through the macroporous resin adsorption post behind the Plate Filtration, flow rate control is the 30-60ml/ branch, ensuing operation is with the pericarp part, promptly use 95% edible ethanol wash-out pillar, access elutriant, reduction vaporization concentrate (temperature: 50-60 ℃, pressure: 160-260mmHg) after do not have the alcohol flavor, after the spraying drying (temperature: 50-60 ℃) Powdered natural pigment.
Present method first Application the macroporous resin adsorption post from DUSIGUO, extract the method for natural pigment, with this method carry pigment be the red-purple pulverulent solids, in the aqueous solution of PH=1-5, take on a red color, in the aqueous solution of PH=6-7, be blue look, in the alkaline aqueous solution of PH=8-12, be green, be applicable to the painted of normal food and beverage, this natural pigment has and does not dye skin, do not dye tongue, the character of lip, it is a kind of water miscible natural food colour, therefore contain flavonoid compound in the pigment again, and flavonoid compound have many biological activitys that human body had health-care effect.Therefore, use in food, beverage with the natural pigment of DUSIGUO as the raw material extraction, not only can make food, beverage is rich in painted aesthetic feeling and promotes appetite of people, but also has certain function of health care.
Embodiment: with 50 kilograms of DUSIGUO as raw material, after selecting clean impurity, washing dedusting with water, with 15-20kg/cm
2Pressure squeezing, get 20 kilograms on 30 kilograms of fruit juice and pericarp, boiling is three times in the pericarp input extractor, add for the first time 100 kilograms in water, get supernatant liquor after centrifugal for 2000-3000 rev/min, residue adds 60 kilograms in water again and decocts after 30 minutes, 2000-3000 rev/min centrifugal, gets supernatant liquor, and residue adds water and decocts for the third time for 60 kilograms, time is 30 minutes, 2000-3000 rev/min centrifugal after, get supernatant liquor and preceding secondary supernatant liquor and merge the back Plate Filtration, by the macroporous resin adsorption post, flow rate control is the 30-60ml/ branch, with 95% edible ethanol wash-out pillar, access elutriant, reduction vaporization concentrates (temperature: 50-60 ℃, pressure: 160-260mmHg) to nothing alcohol flavor, spraying drying (temperature: 50-60 ℃) promptly gets Powdered natural pigment 200g.But pass through the macroporous resin adsorption post behind the fruit juice Plate Filtration, flow rate control is the 30-60ml/ branch, with 95% edible ethanol wash-out pillar, access elutriant, reduction vaporization is concentrated, and (temperature: 50-60 ℃ pressure: 160～260mmHg) to nothing alcohol flavor, and spraying drying (temperature: 50-60 ℃) promptly gets Powdered natural pigment 240g.
Claims (2)
1, the present invention is that a kind of extraction side ā F of natural food colour rinses that the drooping plan of an ancient small-mouthed wine vessel stands up that the young of Buddhist nunnery faints and the pool is pounced on structure and comprised fruit juice, pericarp) be raw material, through purifying and dedusting → squeeze → get skin → poach → centrifugal → placements → supernatant liquor → filtration → by macroporous resin adsorption post → 95% edible ethanol wash-out → get elutriant → reduction vaporization concentrated → drying.
2, method according to claim 1, it is characterized in that the water material weight ratio that drops into when the DUSIGUO severe edema due to hypofunction of the spleen boils is: poach is 5: 1 for the first time, and poach is 3: 1 for the second time, and poach is 3: 1 for the third time, and each poach time was respectively 30 minutes.
