Said method includes the following steps: using black rice bran as raw material, mixing it with edible alcohol accoridng to a certain proportion, pickling at a certain temp., perfectly making zymohydrolysis extraction, and making the mixed extract pass through kieselguhr filter to make treatment, then vacuum concentrating and recovering alcohol, the concentrate is coarse colour matter liquor, making the coarse colour matter liquor pass through NKA macroporous adsorption resin to make purification, successively using water and alcohol to make elution, collecting alcohol eluent, vacuum concentrating and recovering alcohol to obtain high-purity colour matter liquor, concentrating said colour matter liquor, spray-drying and collecting under the sterile condition so as to obtain the invented finished product.
Description
Technical field the present invention relates to a kind of preparation method of food coloring product.
Background technology it is found that along with the deep development of medical science toxicology and biological study the metabolite of synthetic food color in human body that once allows to use has carcinogenesis, therefore uses to be restricted.Natural colouring matter is because safe, painted natural and self nutrition and pharmacological action replaces the application of synthetic food color just gradually.In recent years, the research of extracting natural edible pigment from black rice was more, but the extraction process imperfection, the look valency is not high, and quality is unsatisfactory.
It is raw material with the black rice chaff that summary of the invention the object of the invention is to provide a kind of, through extracting and purifying obtains the preparation method of high luminance relay valency, high-quality natural edible pigment.
The present invention mainly is achieved through the following technical solutions: comprise raw material processing, lixiviate, filtration, absorption, wash-out, concentrate, step such as spray-drying, specific as follows:
One, raw material lixiviate
1, a lixiviate
(the weight kilogram: the volume liter) carry out lixiviate in aseptic jar, alcohol concentration was 0～95%, and extraction temperature is 15～70 ℃, and extraction time is 1～14 hour, and the pH value is 2～6 by 1: 3～1: 9 with black rice chaff and alcohol.
2, secondary lixiviate
(the weight kilogram: the volume liter) carry out lixiviate in aseptic jar, alcohol concentration was 0～95%, and extraction temperature is 30～80 ℃, and extraction time is 2～10 hours, and the pH value is 2～6 by 1: 3～1: 9 with black rice chaff residue and alcohol after the lixiviate.
3, three lixiviates
The ferment of black rice chaff residue adding 0.02～0.1% after the secondary lixiviate is carried out glycolysis, and temperature is 30～60 ℃, and the time is 0.5～2 hour.And then with alcohol (the weight kilogram: the volume liter) carry out lixiviate, alcohol concentration was 0～95%, and extraction temperature is 30～80 ℃, and extraction time is 2～10 hours, and the pH value is 2～6 by 1: 3～1: 9.
The allotment of above-mentioned leaching liquor pH value: 1. can adopt Vc and different Vc-Na compound;
Or 2. adopt citric acid, natrium citricum and V
cCompound;
Or 3. adopt hydrochloric acid and citric acid compound
Two, filter
1, coarse filtration: extract is put hold-up tank room temperature cooling precipitation 7～12 hours into.
2, smart filter: said extracted liquid passes through diatomaceous earth filter.
3, vacuum concentrates: recovered alcohol is soft to the extract.
Three, purifying
1, absorption: above-mentioned concentrate cleans repeatedly with distilled water by NKA macroporous absorbent resin adsorpting pigment again, removes impurity, abandons liquid.
2, wash-out: be adsorbed on natural edible pigment on the NKA macroporous absorbent resin with 40～90% edible alcohol wash-outs, collect and flow out liquid.
Four, drying
1, concentrate: above-mentioned filtrate is carried out vacuum, and to be concentrated into concentration be 15～18%.
2, spray-drying: with adding ferment by 0.1 ‰～0.7 ‰ in the pigment concentrate, make the starch degradation that contains in the concentrate, under 60～85 ℃ of temperature, be incubated 1.5～3 hours, carry out spray-drying then.Dry concrete operations condition is as follows: the concentrate temperature is 55～80 ℃; 125～135 ℃ of EATs, 105～115 ℃ of tower temperature
The present invention has following advantage compared to existing technology:
1. product of the present invention be with countries in the world extensively the accessory substance rice bran of the black rice of plantation be raw material, sufficient raw, cheap;
2. adopt compound extraction, promptly carry out twice acid lixiviate, an enzyme process lixiviate obviously improves the recovery rate of pigment on the one hand, and the pigment residual volume is few in the residue; The digestion agent consumption is few on the other hand, and cost is low, the comprehensive utilization ratio height;
3. adopt Vc and different Vc-Na compound (or citric acid, natrium citricum and Vc is compound; Or hydrochloric acid and citric acid is compound), regulate the leaching liquor pH value, the acid leaching liquor character of gained gentleness, and extraction efficiency is very high;
4. the NKA macroporous absorbent resin is applied to actual production, the natural edible pigment that obtains, look valency E " 100
1% 1cm, product purity is higher than the national standard of existing haematochrome far away.Not only beautiful in colour, and certain medicinal efficacy is arranged, be a kind of natural food colour resource that medical value is arranged;
5. product is a kind of nontoxic, harmless, tasteless natural colouring matter, and its tone can change with the difference of pH value, and acidity is red, and neutrality is baby pink, and alkalescence is that reddish violet is to bluish violet;
6. extracting method is comparatively easy, and technological process is short, and equipment needed thereby is few, and specification requirement is low, and work efficiency height and consuming little energy are free from environmental pollution in the production process;
7. this product purpose is wide, both can be used for the toning of beverage, cold drink and drinks, also can be used for the additive of foodstuffs such as cold cuts class, jam, cakes such as candy class, ham sausage and toiletries, and cost is low, the economic benefit height.The small investment instant effect, big, medium-sized and small enterprises all can go into operation.
