Problems solved by technology

At present, in the caramel color industry, the common method caramel color production process is basically the normal pressure process. The caramelization reaction speed of this method is relatively slow, and the color rate of the product is difficult to achieve more than 15000EBC. The existing common method caramel color product color in the industry The color rate is generally below 15000EBC. Compared with the other three processes, the color

Abstract

The invention relates to a common-process production technique of caramel color with the color ratio of at least 30000EBC, which comprises the following steps: metering and concentrating a raw material, regulating the pH value to 7.0-11.0, adding sodium polyphosphate and propyl gallate as catalysts, carrying out pressurized reaction, terminating the reaction when the color ratio is satisfactory, cooling, filtering, blending, metering and filling. The caramelization reaction is performed by adding the catalysts under increased pressure under alkaline conditions, thereby lowering the activation energy of the reaction system; and thus, the reaction can be performed more easily, and can obtain the high-color-ratio product more easily. No material condensation water is discharged, thereby preventing evaporation heat dissipation and lowering the reaction energy consumption. Since no condensation water is discharged, no peculiar smell or COD (chemical oxygen demand) pollution is generated in the reaction process.

Description

technical field [0001] The invention relates to the technical field of caramel color production, in particular to a common caramel color production process with a color rate ≥ 30000EBC. Background technique [0002] Caramel color is also called caramel color. According to different production processes, caramel color is usually divided into four categories: the first category, common method caramel color, that is, without ammonia (ammonium) and sulfite substances as catalysts, with or The caramel color produced without acid and alkali; the second type, the caustic sulfite method caramel color, uses sulfurous acid and salt substances as catalysts, but does not contain ammonia (ammonium) substances as catalysts, and is produced with or without acid and alkali The obtained caramel color; the third type, the ammonia caramel color, uses ammonia (ammonium) as a catalyst, but cannot use sulfurous acid and salts as a catalyst, and produces the caramel color obtained with or without ...
