Abstract
The invention discloses an extraction method of food additive coloring. The method comprises the following steps: (1) digesting through acetone; (2) performing enzymolysis for pumpkin; (3) centrifugally removing impurities; (4) concentrating the centrifugal liquid; (5) preparing the high-quality coloring. According to the method, lycium barbarum is used as a raw material and processed by organic digestion and other processes; the method is simple, feasible and low in cost, and meanwhile, the color value of lycium barbarum red and the recovery rate can be ensured; the pumpkin is refined by impurity removing through an enzymic preparation, so that some non-volatile ingredients can be separated and removed, and therefore, the product is relatively high in color value; the coloring produced by the method has the advantages that the utilization rate of the raw material is greatly increased, the application field of food additives is expanded while the coloring quality is improved, and the development of related industries is promoted.
Description
Technical field
The invention belongs to technical field of pigment extraction, be specifically related to the extracting method that a kind of food additive adds pigment.
Background technology
Wolfberry pigment is all kinds of present-color materials be present in matrimony vine berry, is the important physiologically active ingredient of matrimony vine seed.Mainly comprise-carotene, xenthophylls and other coloring matters.Carotenoid contained by matrimony vine then has very important pharmaceutical use.A lot of research has proved that matrimony vine seed pigment has and has improved the effects such as immune function of human body, prevention and prohibition tumour and prevention of arterial are atherosis.Carotene is the main active ingredient of wolfberry pigment, has anti-oxidant and as the important physiological function of the synthesis precursor etc. of vitamin A.
Pumpkin contains abundant carotene and vitamins C, can invigorating the spleen, and prevention gastritis, prevents and treats nyctalopia, protect liver, makes skin become delicate, and in having and the effect of carcinogenic substance.Yellow fruits and vegetables are also rich in two kinds of vitamin A and D; Vitamin A can protect gastrointestinal mucosa, prevents the illness such as gastritis, stomach ulcer from occurring; Vitamins D has the effect promoting calcium, phosphorus two kinds of mineral elements absorptions, and then receives the merit of the strong muscle of strong bone, the common diseases such as children rachitis, adolescent myopia, middle-aged and senile osteoporosis is had to the effect of certain prevention.
Current Extraction of Pigment is logical exists complex procedures, and solvent load and consumption are all comparatively large, and process costs is high, and realize industrialization investment comparatively large, the industrialization technology improving product quality exists obstacle.
Be of high nutritive value by extracting from natural fruits, to human body without any undesirable action, and also good to light, hot stability and chemical stability, toning field width, the health-care pigment that can adapt to multiple requirements is significant.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides the extracting method that a kind of food additive adds pigment, its technique is simple, cost is low, is easy to realize suitability for industrialized production, and the pigment obtained is of high nutritive value, to human body without any undesirable action, and good to light, hot stability and chemical stability.
The technical scheme that the present invention takes is:
Food additive adds an extracting method for pigment, it is characterized in that, comprises the following steps:
(1) acetone extraction: according to matrimony vine gravimetric value, adds the acetone soln of 3-4 times of 60-70%, raised temperature 60-70 DEG C, lixiviate 30-40min, under 30-40 DEG C of condition, is uniformly mixed 40-50min, obtains matrimony vine with the rotating speed of 150rpm;
(2) pumpkin enzymolysis: add the lipase of 40% and the polygalacturonase of 60% in pumpkin, enzymolysis 30-40min removes impurity, then uses hexane lixiviate 50-60min, obtains lixiviate liquid;
(3) centrifugal removal of impurities: by medlar liquid and the mixing of pumpkin enzymolysis solution, with Centrifugal Machine Control flow 200L/h, rotating speed 8000-12000rpm, carry out high speed centrifugation and be separated the various impurity of removing and throw out, collect centrifugate;
(4) concentrated centrifugate: regulate pH=9-10 with alkali lye, control extraction temperature 70-80 DEG C, extract above-mentioned centrifugate, by the supernatant liquor hcl acidifying after extraction to pH=6-7;
(5) product processed: antioxidant centrifugate being added 0.5-0.8%, carries out being concentrated into 30-35% and sloughing dissolvent residual, recovered solvent recycle, obtains high-quality haematochrome.
In above-mentioned step (4), alkali lye comprises sodium hydroxide solution or sodium carbonate solution.
The mixture of to be Tyox B and the tertiary butyl to hydroxytoluene according to weight ratio the be 2:1 of the antioxidant in above-mentioned step (5).
The beneficial effect of the invention:
The present invention utilizes matrimony vine for raw material, by techniques such as organic lixiviates, and simple possible, cost is low, and guarantee the red valency rate of recovery of matrimony vine, pumpkin is by the use impurity removal and purification of zymin simultaneously, make the separated removing of a part of non-volatility composition, ensure that product has higher look valency.The pigment that the present invention obtains substantially increases the utilization ratio of raw material, in raising pigment quality simultaneously, expands foodstuff additive Application Areas, and promotes that related industries develops.
