Description
Technical field
The invention belongs to food additives production technical field, is related to a kind of beet red pigment handling process, specifically
It is related to a kind of beet red pigment emulsifying process.
Background technology
With economic development and the improvement of people's living standards, nowadays requirement of the people to food is not solely restricted to inside
Quality, while the also more and more higher of the requirement to food appearance quality, and the color and luster of food occupies phase in food appearance quality
Work as consequence, therefore the research to food color has been increasingly becoming study hotspot.
Food color includes synthetic dyestuff and natural pigment, natural pigment with it is safe, some are with preventing and treating disease
The health-care effect of disease, containing required nutriment, tone is natural, can imitate the advantages of natural colored, from animals and plants and micro-
Safe natural pigment is extracted in biomaterial as food color and receives much concern and payes attention to.
In numerous natural food Agents, beet red pigment is widely used a kind of edible natural pigment in the world,
It is present in the various plants such as Amaranthaceae, Chenopodiaceae, seaweed jasmine section, is extracted more from the root tuber of Chenopodiaceae red beet, beet red pigment
Colorability is strong, nontoxic, safe, and also having improves liver function, anti-oxidant, anticancer, anti-aging, reducing blood lipid, protect eyes, promotion
The effect digested and assimilated, be one of preferable natural red colouring matter of substitution synthesis haematochrome, be widely used in beverage, ice cream, wine,
Candy, cake mounting flower, the processing of tank first-class product.
But beet red pigment is easily soluble in water, can not be dissolved in grease, easily there is pigment in the high food of oil content
Aggregation, disperse the problem of uneven, so as to limit its application in the high food of oil content (such as white chocolate).
The content of the invention
Therefore, the technical problems to be solved by the invention are that traditional beet red pigment does not dissolve in grease, in floorboard with high oil content
Easily assemble in food, make the scattered inequality of food colour, the outward appearance of food is have impact on, so as to propose that one kind turns into beet red pigment
The beet red pigment emulsifying process of oily soluble/dispersible pigment.
In order to solve the above technical problems, the technical scheme is that：
The present invention provides a kind of beet red pigment emulsifying process, and it comprises the following steps：
S1, it is ground after beet red pigment powder is mixed with oil phase dispersion liquid, obtains oil mixture, the beet
Haematochrome powder accounts for the 5~30% of the oil mixture gross mass；
S2, emulsifying agent is added into the oil mixture, and carry out vacuum emulsification, the addition of the emulsifying agent is oil
The 5-20% of phase mixture.
Preferably, also include using in the beet red pigment powder before mixing with oil phase dispersion liquid in the step S1
The step of microencapsulation material processing.
Preferably, in the step S1, the grinding carries out ball milling, the grinding-material of the ball mill using ball mill
For steel ball, zircon pearl or agate bead, the rotating speed of the ball mill is 5-3000r/min.
It is preferably, cold to ball mill progress using cooling water of the temperature not higher than 30 DEG C in the process of lapping
But, the mixture actual temperature of beet red pigment and oil phase dispersion liquid is not higher than 30 DEG C in mechanical milling process, and the oil phase after ball milling mixes
Compound particle diameter is not more than 5 μm.
Preferably, in the step S2, in the step S2, the vacuum emulsification is carried out in vacuum emulsification tank, institute
The mixing speed for stating emulsion tank is 5-1000r/min, and vacuum is -0.2-0Mpa, emulsification times 10-30min.
Preferably, the oil phase dispersion liquid is low melting point grease, the emulsifying agent is lipophilic emulsifier.
Preferably, the oil phase dispersion liquid is sunflower oil, rapeseed oil or soybean oil；The emulsifying agent is citric acid fat
Fatty acid glyceride, sucrose ester, soybean lecithin or polyglycerol polyricinoleate.
Preferably, the emulsifying agent is made using sunflower oil, rapeseed oil or soybean oil as raw material.
Preferably, the color value of the beet red pigment is 4E-200E.
Preferably, the wall material of the microcapsules is cyclodextrin.
The above-mentioned technical proposal of the present invention has advantages below compared with prior art：
Beet red pigment emulsifying process of the present invention, it includes grinding beet red pigment powder with oil phase dispersion liquid
Grind, prepare oil mixture and the step of by the oil mixture and emulsifying agent vacuum emulsification, water-soluble beet red pigment warp
Together ground with oil phase dispersion liquid and after emulsification treatment, oil-based system is dispersed among, so as to be used in oil phase, for improving
The exterior quality of the higher food of oil content, it is therefore prevented that the uneven situation of pigment deposition, distribution of color in the high food of oil content,
The application of beet red pigment is expanded, emulsifying process is simple, and equipment investment is few, and production cost is low.
Embodiment
In order that present disclosure is more likely to be clearly understood, below according to specific embodiment of the invention to this hair
It is bright to be described in further detail.
