Embodiment 1

[0027] Set the production of 36Be, 50000EBC caustic acid salt method caramel color (EBC is the color rate unit of caramel color; Be refers to the Baume value of caramel color, and color rate and Baume are the measurement indicators of caramel color), the specific steps are as follows:

[0028] 1) Raw material metering and concentration: maltose (the amount of dry matter is 6000Kg, DE value is 42%, and DE value refers to the mass percentage of reducing sugar in dry matter;) is pumped into the reaction tank, and the raw material is concentrated to dryness in the reaction tank. Basis is 65%;

[0029] 2) pressurized catalytic reaction for the first time: add 300kg (5% of the amount of maltose dry matter) sodium hyposulfite to the concentrated material, 18kg (0.3% of the amount of maltose dry matter) sodium hydroxide, heat up in the reaction tank and add Pressure reaction (the range of temperature rise is controlled at 110-130°C, and the range of pressurization is controlled at 0.1...

Embodiment 2

[0041] Set to produce 36Be, 60000EBC caustic acid salt method caramel color, the specific steps are as follows:

[0042] 1) Raw material metering and concentration: pump fructose and glucose into the reaction tank at a ratio of 1:1 (the amount of dry matter is 6000Kg, and the DE value is 97%), and the raw material is concentrated to 85% on a dry basis in the reaction tank ;

[0043] 2) pressurized catalytic reaction for the first time: add 1800kg potassium pyrosulfite and sodium pyrosulfite (wherein potassium pyrosulfite 900Kg), 1800kg sodium bicarbonate and sodium acetate (wherein sodium bicarbonate 1000Kg) in the concentrated material, Temperature rise and pressure reaction in the reaction tank (the range of temperature rise is controlled at 165-180°C, and the range of pressurization is controlled at 0.65-0.8Mpa), and the color rate is detected by sampling every 30 minutes. When the color rate is 0.076, the first reaction is terminated;

[0044] 3) The second atmospheric pr...

Embodiment 3

[0055] Set to produce 36Be, 50000EBC caustic acid salt method caramel color, the specific steps are as follows:

[0056] 1), Raw material metering and concentration: pump molasses, xylose and sucrose into the reaction tank according to the ratio of 1:1:1 (the amount of dry matter is 6000Kg, and the DE value is 60%), and the raw materials are concentrated to dryness in the reaction tank. 75% basis;

[0057] 2) The first pressurized catalytic reaction: add 900kg sodium bisulfite, 900kg sodium citrate, potassium hydroxide and sodium carbonate (wherein sodium citrate 600kg, potassium hydroxide 100Kg) in the concentrated material, in the reaction tank Internal heating and pressurization reaction (the range of temperature rise is controlled at 165-180°C, and the range of pressurization is controlled at 0.65-0.8Mpa), and the first reaction is terminated when the color ratio is 0.063;

[0058] 3) The second atmospheric pressure catalytic reaction: cool the material completed for the ...

Abstract

The invention discloses a preparation method for improving the caramel color rate of a caustic sulfite method. According to the catalytic reaction, different catalysts are added for three times underthe condition of normal pressure or pressurization to carry out three times of staged reaction. According to the preparation method of the caramel color, the problem that the caramel color rate is difficult to increase by the caustic sulfite method can be solved, the color rate of the product can be increased to 50000 EBC or above, and the product has the advantages of being good in quality, low in sulfur dioxide residue, stable in coloring and good in wine resistance.

Description

technical field [0001] The invention relates to the technical field of caramel color production, in particular to a preparation method for improving the color rate of caramel by caustic sulfite method. Background technique [0002] Caramel color, commonly known as caramel, also known as caramel color, has a wide tradition of use in my country and is one of the most used food colorings. According to different production processes, caramel color is divided into four categories: the first category, common method caramel color, is produced with carbohydrates as the main raw material, with or without acid (alkali), and without ammonia compounds and sulfites. Caramel color; the second category, caustic sulfite caramel color, the caramel color produced by using carbohydrates as the main raw material, in the presence of sulfite, with or without acid (alkali), and without using ammonia compounds; The third category, ammonia caramel color, caramel color produced with carbohydrates as...
