Abstract

The invention belongs to the technical field of food additives and provides a preparation method of edible color lake based on calcium carbonate. The preparation method comprises steps as follows: S1,dissolving carbonate in water to obtain a carbonate solution; S2, dissolving water-soluble anionic pigment in the carbonate solution obtained in S1 to obtain a mixed solution; S3, adding hydrochloricacid to the mixed solution obtained in S2, and adjusting the pH to 7-10.54; S4, dissolving calcium salt into water, then adding an obtained solution to the solution obtained in S3, controlling the pHof the solution in the range of 6-9, and performing ultrasonic treatment for 1-10 min and centrifugation to obtain calcium carbonate precipitates adsorbing pigments; S5, drying and grinding the calcium carbonate precipitates adsorbing pigments to obtain the edible color lake based on calcium carbonate. The insoluble problem that aluminum color lake has potential safety hazard is solved.

Description

technical field [0001] The invention belongs to the technical field of food additives and relates to a preparation method of an edible color lake based on calcium carbonate. Background technique [0002] Lake is a non-water-soluble pigment product made by adsorbing water-soluble pigments on a water-insoluble matrix in an aqueous solution, and then separating and drying the resulting precipitate (matrix with pigment adsorbed). Compared with the pigment itself, the color lake has better dispersibility, and can dye high-fat foods (such as cream and chocolate, etc.) and dry powder foods (such as milk powder). Color lakes are widely used and have low substitutability, and are essential raw materials in the food, pharmaceutical and cosmetic industries. [0003] In the preparation of edible lakes, aluminum hydroxide is the most widely used traditional adsorption matrix. At present, the lakes approved for use in my country's food additive use standards are all aluminum hydroxide l...
