Problems solved by technology

In such a process, the active ingredients in red beet are extracted independently. During the refining process, some components that can enhance its stability are selectively and forcibly intercepted. The obtained beet red pigment is very different from its inherent components. As a result, the product itself has poor stability and is sensitive to heat, light, pH value, oxygen and other factors, and its application range is limited
The process uses ultrafiltration, nanofiltration and other refining methods, which have high requirements for equipment, high production costs, and limited industrialization

Embodiment 1

[0009] Embodiment 1: Take 100kg of special-purpose variant red beets for pigment, repair, wash, cut into slices with a thickness of about 5mm, immerse in an equal amount of water with a temperature of 90°C and containing 1% sodium sulfite, scald to kill the enzyme for 5min, and then cool rapidly to 25°C, use a continuous juicer to squeeze the juice, collect 90.2kg of beet juice, add D-isoVc sodium antioxidant 0.18kg, mix well, add ZTC1+1 natural clarifier 0.07kg, mix and flocculate place, produce precipitation, and the upper layer is cleared at night using a tube centrifuge, with a speed of 12000rpm and a flow rate of 250L / h, to obtain 87.5kg of centrifugate containing beet red pigment. The centrifugate is concentrated under vacuum conditions using a falling film evaporator to obtain liquid beet The red pigment is 21.5kg, the unit color price is 3.5, the product is clear and transparent without precipitation after dissolving in water, and has strong stability. Under the conditi...

Abstract

The invention relates to a process for producing high-stability beet red pigment, and belongs to the technical field of natural pigment production. The process comprises the following steps: (1) hot burning and enzyme inactivation, namely trimming, cleaning and slicing variant red beet special for the pigment, hot-burning the red beet in sodium sulfite water to inactivate enzyme, and then quicklycooling the red beet; (2) oxidation, namely juicing the cooled red beet by using continuous juicing equipment, collecting the obtained juice, and adding antioxidant into the juice; (3) settlement, namely adding a clarifying agent into the juice, and flocculating and standing the mixture after uniformly mixing to flocculate and settle the insoluble components and impurities; (4) high-speed centrifugal separation, namely performing centrifugal separation on the mixture by a tubular centrifugal machine to remove the heavy-phase impurities so as to obtain clarified juice containing the beet red pigment; and (5) vacuum concentration, namely condensing the clarified juice under the vacuum condition by using a film evaporator so as to obtain the liquid beet red pigment. The process is simple, safe and reliable, has low cost and high stability of the product, and is convenient for industrialized production.

Description

technical field [0001] The invention relates to a production process of a highly stable beet red pigment, belonging to the technical field of natural pigment production. Background technique [0002] Beet red pigment is a water-soluble natural pigment extracted from red beet, a variety of Chenopodiaceae plant beet. Generally speaking, beet red pigment is the general term for all colored compounds in red beet, which is composed of red beet anthocyanin and yellow beta xanthin. Beet cyanine mainly includes betaine, isobetaine, probetaine and isoprobetaine. Betaflavin mainly includes betaflavin I and betaflavin II. Beet red pigment is bright and natural, has no toxic side effects, no special smell, and has certain health care functions. It can be conveniently applied to the coloring of ice cream, dairy products, candies, cakes, cans, etc., especially widely used in the coloring of low-temperature foods. An ideal natural red pigment resource. [0003] However, there are some ...
