Problems solved by technology

[0003] The coloring of beverages is also very important. Caramel pigment for beverages is a kind of food additive colorant. Many domestic enterprises use sucrose or waste molasses as raw materials to decompose and dehydrate incompletely at high temperature. This process Limited resources cannot meet the market demand for special caramel coloring for beverages

Abstract

The invention discloses a method for preparing special caramel pigment for beverages, which comprises the following steps: (1) chromatographic separation; (2) separation: cooling the glucose AD solution prepared in step (1) to 45-50°C, and then According to the order of strongly acidic cation→weakly basic anion→strongly acidic cation→weakly basic anion, impurities are removed through ion exchange resin in turn; (3) concentration; (4) isomerization; (5) mixing to obtain a mixed solution; (6) ) decolorization and filtration; (7) separation; (8) concentration; (9) heating and boiling; (10) adding ammonium sulfite; (12) refining: adding edible alkali to the caramel pigment prepared in step (11) Adjust the pH value of the caramel solution to 4.5-5.5, and then further filter and refine to obtain the finished caramel coloring. The invention uses the glucose mother liquid discharged after the separation of crystallized glucose as raw material, turns waste into treasure, comprehensively utilizes it, and improves the utilization rate of resources in the glucose preparation process.

Description

technical field [0001] The invention belongs to the field of caramel pigment production, and in particular relates to a special caramel pigment for beverages and a preparation method thereof. Background technique [0002] Caramel pigments are widely used in the food industry, such as for coloring soy sauce, vinegar, pickles, beverages, wines, pastries, chocolates, candies, soups, syrups and medicines. At present, many domestic production enterprises use waste molasses from sugar production as raw materials to produce caramel pigment, but the resources are relatively limited and cannot meet the production needs of enterprises. Therefore, it is particularly urgent to seek a large amount, cheap raw material suitable for caramel pigment processing. [0003] The coloring of beverages is also very important. Caramel pigment for beverages is a kind of food additive colorant. Many domestic enterprises use sucrose or waste molasses as raw materials to decompose and dehydrate incompl...
