Mix and stir12h, then in90℃Underheating1hto kill the enzyme; let it sit overnight, separate the oil layer, and reduce the pressure (133.3～666.6Pa)Distillate to remove water and low-boiling point substances to obtain oil-containing pigments965g; add to it100gRefined olive oil, using a centrifugal thin-film molecular distillation device under vacuum0.1066Pa、170℃ Carry out molecular distillation under the conditions to distill out specific odorous components and fatty acids, and obtain a color value that is basically odorless22.6万的chrome 420g.
3. Transesterification reaction-volumetric method
at3LMethanol added 40gSodium metal, then add1． 5kgColor value10Wan’s capsicum oleoresin, reflow3h, perform transesterification reaction. Excess methanol is then distilled off and the residue is poured into5LWarm water in, and adjust the pH with dilute hydrochloric acidpHValue to4~6. After letting it stand for layering, take the oil layer and add it7.5L Hexane, separate out the pigment and filter to obtain155gColor value65Thousands of non-spicy capsicum red pigments.
New separation technology can also be used——Supercritical extraction method to extract capsicum red pigment.
Purpose
As a food coloring agent, Guidong, my country It can be used for color decoration on biscuits, candies, cold drinks, cooked meat products, artificial crab meat, sauces and pastries. Use in appropriate amounts according to production needs.
