Problems solved by technology

[0003] Zeaxanthin is a kind of fat-soluble oil. Because it contains unsaturated double bonds, it presents bright colors such as red or yellow. When it is above 10°C, it is a blood-red oily liquid, and below 10°C, it is a yellow semi-solidified oil. It is not easy to transport and process. At the same time, the highly unsaturated structure also causes the change of environmental conditions to damage the zeaxanthin to varying degrees. Its chemical properties are unstable, and it is easily degraded and isomerized by the influence of light or heat in the external environment. , which limits its scope of application

Abstract

The invention discloses a preparation method of maize yellow pigment micro powder, and relates to the technical field of corn deep processing. The mass ratio of a core material to the wall material is 1:(1-3), the core material is a maize yellow pigment; the wall material comprises the following components by content: 20-30% (w / w) of malt syrup, 50-60% (w / w) of beta-cyclodextrin, 5-15% (w / w) of modified starch and 2-5% (w / w) of zein; the sucrose fatty acid ester and the single and double stearic acid glyceride are taken as compound emulsifiers, and the content of the compound emulsifier in the solid solids is 0.6-1.5% (w / w). The preparation method is simple in technology, low in energy consumption, high in safety, and high in yield of the maize yellow pigment, the yield can be up to 89-97%, the embedding rate of the pigment is obviously improved, and the pigment is good in stability and easy to be dissolved in water, has good viscosity, and can be widely applied to the industries such as foods, medicines, cosmetics and even feeds.

Description

technical field [0001] The invention relates to the technical field of corn deep processing, in particular to a preparation method of corn yellow pigment micropowder. Background technique [0002] Zeaxanthin is a kind of natural pigment widely present in many plants. Its main component is carotenoid, which is composed of lutein, zeaxanthin, cryptoxanthin and β-carotene. At the same time, zeaxanthin belongs to the isoprene pigment, which not only has the function of natural food coloring, but also can be used in margarine, margarine, candy, ice cream, seasoning, edible oil, and is a natural nutritional enhancer with anti-oxidation properties. , eliminating free radicals, anti-cancer, reducing the incidence of cardiovascular disease and visual protection and other important physiological functions, it can be used in food, medicine, health care products, cosmetics and even feed industries. At present, zeaxanthin has been approved as a food coloring by many countries in Europe ...
