Abstract
The invention discloses a method for improving a color tone of a beet red pigment, comprising the following steps of: extracting red beets; filtering and concentrating to obtain a beet red concentrated solution; and adding a color tone modifying agent into the beet red concentrated solution to react under an ultrasonic condition to obtain the beet red pigments with the different color tones. According to the method, the color tone modifying agent is added so that the color tone of a beet red product can be changed and the specifications of beet red products are enriched; the adding amount of the color tone modifying agent is changed from small to large and the color tone is changed to reddish violet from red, and therefore, the application requirements of different color tone requirements on all aspects can be met through adjusting the adding ratio of the color tone modifying agent. The method utilizes ultrasounds to help the modification of the color tone, so that the modification efficiency of the color tone is high and the effect is better.
Description
Technical field
The present invention relates to a kind of beet red pigment purification techniques, especially a kind of method of improving the beet red pigment tone.
Background technology
Beet red pigment is widely used a kind of edible natural pigment in the world, and main component is the beet red glycosides, is present in the various plants of the sections such as Amaranthaceae, Chenopodiaceae, Nyctaginaceae, Phytolaccaceae.Betacyanins are to replace one of synthetic optimal natural red colouring matter of haematochrome, it is to be obtained through refining by vegetables to form, nontoxic, safety and be improved the effect that liver function, promoting digestion absorb, can be widely used in the food such as beverage, fruit wine, cake, be one of chemosynthesis haematochrome best substitute, have good exploitation and be worth.
The tone of beet red pigment is single at present, and the tone of customer demand is not quite similar from the redness to the red-purple.But the product shade of producing at present is wayward, this so that the range of application of beet red be limited by very large, can not satisfying the market to the demand of product special colour.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method of improving the beet red pigment tone that changes pigment Lab value, to obtain the beet red pigment of different tones.
For solving the problems of the technologies described above, the technical solution used in the present invention is: red beet is extracted, obtain the beet red concentrated solution after filtering, concentrating; Described beet red concentrated solution adds the tone modifying agent, reacts under ultrasound condition, can obtain the beet red pigment of different tones.
Tone modifying agent of the present invention is the mixture of water-soluble rosemary extract and Quercetin mass ratio 1:4.The add-on of described tone modifying agent is 1%～5% of beet red concentrated solution quality.Described temperature of reaction is 35～50 ℃, and the reaction times is 20～50min; Described ultrasonic power is 800～1000W.
The extracting method of red beet of the present invention is: chopping after red beet is cleaned, then extract with the extraction solvent that is added with stablizer; Described stablizer is the mixture of water-soluble rosemary extract and Quercetin mass ratio 1:1.Be added with the stablizer of 0.1wt%～1wt% in the described extraction solvent.Described extraction solvent is that the pH value is 3.0～3.5 aqueous citric acid solution.Described red beet is with the extraction solvent extraction of 2 times of volumes.
Filtration procedure of the present invention is: extracting solution successively through 10 μ m and 1 μ m deep bed filter filter, 0.22 μ m ceramic membrane filter, the SD-300 macroporous resin treatment.
Concentration process of the present invention is: extracting solution successively and thin-film evaporator concentrated through nanofiltration membrane concentrates.The concentrated condition of described thin-film evaporator is: flow 200L/h, 60～65 ℃ of temperature, vacuum tightness 0.08～0.09MPa.
The beneficial effect that adopts technique scheme to produce is: the present invention passes through to add the tone modifying agent, thereby can change the tone of beet red product, enriches the specification of beet red product; Tone modifying agent addition is ascending can make tonal variation by redness to red-violet colour, by adjusting tone modifying agent adding proportion, can satisfy the application demand of the different tone requirements of each side like this.The present invention uses ultrasonic complementary colors to adjust and reform very, thereby makes high, the better effects if of tone improvement efficient.
The present invention adopts rosemary extract and Quercetin, has taken into account to strengthen stable, tone improvement, the effect of synergy three aspects:.When rosemary extract and Quercetin 1:4 proportioning, can play the effect of tone improvement; Help enhanced stability during the 1:1 proportioning.
The present invention especially introduces the thin film concentration technology, thereby can effectively protect product shade, ensures the product yield.
