Embodiment 1

[0023] A kind of preparation method of ammonium sulfite method caramel color, comprises the following steps:

[0024] 1) Add glucose syrup with a solid content of 60% to the reactor, heat up to 80°C, then add 5% sodium sulfite on a dry basis of the glucose syrup and ammonium sulfate with 4% on a dry basis of the glucose syrup, and adjust the temperature in the reactor to 130 ℃, pressure to 0.10MPa, react for 30min;

[0025] 2) Adjust the temperature in the reactor to 120°C, the pressure to 0.05MPa, and react for 120min;

[0026] 3) Adjust the temperature in the reactor to 115°C, the pressure to 0.01MPa, and react for 180min;

[0027] 4) Rapidly adjust the temperature in the reactor to 50° C., the pressure to normal pressure, and filter to obtain caramel color.

Embodiment 2

[0029] A kind of preparation method of ammonium sulfite method caramel color, comprises the following steps:

[0030] 1) Add fructose syrup with a solid content of 75% to the reactor, heat up to 85°C, then add potassium sulfite with 15% dry basis of fructose syrup and ammonium phosphate with 5% dry basis of fructose syrup to adjust the reaction The temperature in the kettle is 132°C, the pressure is 0.12MPa, and the reaction is 45min;

[0031] 2) Adjust the temperature in the reactor to 123°C, the pressure to 0.08MPa, and react for 150min;

[0032] 3) Adjust the temperature in the reactor to 118°C, the pressure to 0.03MPa, and react for 150min;

[0033] 4) Quickly adjust the temperature in the reaction kettle to 55° C., the pressure to normal pressure, and filter to obtain caramel color.

Embodiment 3

[0035] A kind of preparation method of ammonium sulfite method caramel color, comprises the following steps:

[0036] 1) Glucose syrup with a solids content of 85% is added to the reactor, the temperature is raised to 90° C., and then sodium bisulfite and 1% ammonia on a dry basis of the glucose syrup and 1% of the dry basis of the glucose syrup are added (actually added is the mass Fraction of 26% ammonia water, and then converted to calculate the amount of ammonia), adjust the temperature in the reactor to 135 ° C, the pressure to 0.15 MPa, and react for 60 minutes;

[0037] 2) Adjust the temperature in the reactor to 125°C, the pressure to 0.10MPa, and react for 180min;

Abstract

The invention discloses a preparation method of caramel color by an ammonium sulfite method. The preparation method comprises the following steps: 1) adding syrup into a reaction kettle, heating to 80-90 DEG C, adding sulfite, ammonia or / and ammonium salt, adjusting the temperature in the reaction kettle to 130-135 DEG C and the pressure to 0.10-0.15 MPa, and reacting for 30-60 minutes; 2) adjusting the temperature in the reaction kettle to 120-125 DEG C and the pressure to 0.05-0.1 MPa, and reacting for 120-180 minutes; 3) adjusting the temperature in the reaction kettle to 115-120 DEG C, adjusting the pressure to 0.01-0.05 MPa, and reacting for 120-180 minutes; and 4) adjusting the temperature in the reaction kettle to 50-60 DEG C, adjusting the pressure to normal pressure, and filtering. In the caramelization reaction process, escape of free sulfur dioxide is promoted by gradually reducing the pressure in the reaction kettle, and the residual amount of sulfur dioxide in the finallyprepared caramel color is lower than 0.03% and is lower than that of a conventional ammonium sulfite method caramel color product by 70% or above.

Description

technical field [0001] The invention relates to a method for preparing caramel color by an ammonium sulfite method, and belongs to the technical field of food additives. Background technique [0002] Caramel color, also known as caramel pigment, is a complex reddish-brown or dark-brown mixture formed by dehydration, decomposition and polymerization of sugar substances (such as maltose, sucrose, molasses, lactose, etc.) at high temperatures. It is a semi-natural color that is widely used. food coloring agent. Ammonium sulfite method caramel color refers to the caramel color obtained by using carbohydrates as the main raw material, in the presence of ammonia compounds and sulfites, with or without acid (alkali). GB 2760-2014 "National Food Safety Standard Food Additive Use Standard" stipulates that ammonium sulfite caramel color can be used in condensed milk, various beverages, cocoa products, chocolate products, candy, batter, instant cereals, biscuits, soy sauce, sauce In ...
