Problems solved by technology

[0004] Adding 0.1% ammonia caramel color to vinegar cannot meet the needs of customers. Customers can only choose to use common method caramel color for vinegar coloring. Although common method caramel color is safer than ammonia caramel color, the biggest The disadvantage is that the acid resistance is not as good as the ammonia caramel color, and there is no precipitation or turbidity

Embodiment 1

[0025] Set the production of 36Be, 20000EBC caramel color (EBC is the color rate unit of caramel color; Be refers to the Baume value of caramel color, and both color rate and Baume are the measurement indicators of caramel color); the specific steps are as follows:

[0026] (1) Metering feed: the amount of dry matter is 6000kg of maltose syrup metered into the reaction tank, and the temperature rises and concentrates the dry basis to 65%;

[0027] (2) The first step of reaction: add 36kg of hydrochloric acid and 3kg of other acids, pressurize and heat up to react until the color rate is 0.050, stop the first step of reaction;

[0028] (3) The second step of reaction: After the first reaction is completed, add 3.0kg of Grignard reagent, the flow rate is 39mL / min carbon dioxide, and react at normal temperature and pressure until the color rate is 0.076;

[0029] (4) The third step reaction: After the second reaction is completed, add liquid caustic soda to adjust the caramel col...

Embodiment 2

[0037] Set to produce 36Be, 20000EBC caramel color, the specific steps are as follows:

[0038] (1) Metering feed: the amount of dry matter is that the glucose syrup of 10000kg is metered into the reaction tank, and the temperature rises and concentrates the dry basis to 75%;

[0039] (2) The first step reaction: add 60kg hydrochloric acid and 5kg other acids, pressurize and heat up to react until the color rate is 0.050, stop the first step reaction;

[0040] (3) The second step of reaction: after the first reaction is completed, add 8 kg of Grignard reagent, feed in gaseous carbon dioxide at a flow rate of 65 mL / min, and react at normal temperature and pressure until the color rate is 0.076;

[0041] (4) The third step reaction: After the second reaction is completed, add liquid caustic soda to adjust the caramel color to pH 6.8, maintain the temperature at 108°C, and stir for 30 minutes, then cool to terminate the reaction;

[0042] (5) Blending: pump the materials into th...

Embodiment 3

[0048] Set to produce 36Be, 20000EBC caramel color, the specific steps are as follows:

[0049](1) Metering feed: the amount of dry matter is that the fructose syrup of 15000kg is metered into the reaction tank, and the temperature rises and concentrates the dry basis to 85%;

[0050] (2) The first step reaction: add 90kg hydrochloric acid and 7.5kg other acids, pressurize and heat up to react until the color rate is 0.050, stop the first step reaction;

[0051] (3) The second step of reaction: after the first reaction is completed, add 6.0kg of Grignard reagent, feed in gaseous carbon dioxide with a flow rate of 97.5mL / min, and react at normal temperature and pressure until the color ratio is 0.076;

[0052] (4) The third step reaction: After the second reaction is completed, add liquid caustic soda to adjust the caramel color to pH 7.0, maintain the temperature at 113°C, and stir for 30 minutes, then cool to terminate the reaction;

[0053] (5) Blending: pump the materials ...

Abstract

The invention discloses a preparation method for improving the acid resistance of common caramel color, which includes metering and concentration of raw materials and catalytic reaction. The specific steps of catalytic reaction are as follows: 1) One-time reaction: adding hydrochloric acid and other acid solutions to raw material starch syrup, heating and adding 2) Secondary reaction: Add Grignard reagent to the material obtained in the first reaction, and react at normal temperature and pressure. During the reaction, according to the amount of raw material syrup, continue to feed gas carbon dioxide to the required 3) three times of reaction: add liquid caustic soda to the material after the secondary reaction is terminated to adjust the pH to 6.5-7.0, heat up for 30 minutes, cool to terminate the reaction, and filter to obtain acid-resistant caramel color. The method for improving the acid resistance of ordinary caramel color of the present invention can improve the acid resistance of ordinary caramel color through a three-step reaction, ensure stability in acidic environments such as vinegar, and prevent turbidity and precipitation.

Description

technical field [0001] The invention relates to the technical field of caramel color production, in particular to a preparation method for improving the acid resistance of common caramel color. Background technique [0002] Caramel color, also known as caramel color, has a tradition of being widely used in my country and is the most used food coloring. According to different production processes, caramel color is divided into four categories in the world: common method caramel color: that is, caramel color produced with or without acid and alkali without ammonia (ammonium) and sulfite substances as catalysts; Caustic sulfite method caramel color: using sulfurous acid and salt substances as catalysts, but not containing ammonia (ammonium) substances as catalysts, caramel color produced with or without acid and alkali; ammonia method caramel color: using ammonia (ammonium) ) substances as catalysts, but cannot use sulfurous acid and its salts as catalysts to produce caramel c...
