Embodiment Construction

[0020] The preparation method of the caramel color provided by the present invention is that air (or oxygen) is input into the bottom of the airtight reaction container that sugar solution is housed, and the air rises above the liquid level from the bottom of the reaction kettle, and the exhaust pipe above the reaction kettle discharge.

[0021] In an embodiment of the invention, the process of the whole reaction has oxygen to participate all the time:

[0022]

[0023] Oxygen catalyzes the oxidation of sugar in the whole process, overcomes the disadvantages of high energy barrier in some reaction processes, and shifts the reaction balance of caramel color synthesis to the side of melanoid formation, thereby improving the utilization rate of sugar in the coking process. At the same time, the utilization rate of the auxiliary agent is correspondingly improved, and the residue of the auxiliary agent in the finished product is effectively reduced. At the same time, the existe...

Abstract

The invention relates to a method for preparing caramel colour, which comprises the step of: introducing air into the bottom of a closed reaction container filled with sugar liquid to ensure that the air raises from the bottom of the reactor container and is exhausted through the upside of the reaction container, wherein oxygen participates in the catalytic reaction in the whole process, thus the consumption of other assistants is greatly reduced, and the caramel colour with low residual quantity of the assistants and good salt resisting property is rapidly produced. The invention also provides a device used in the preparation method.

Description

technical field [0001] The invention relates to a production process of a food additive, in particular to a method for preparing caramel color. [0002] The present invention also relates to a device for realizing the above-mentioned preparation method. Background technique [0003] At present, the production of caramel color is divided into two types: open reaction and closed reaction. The open reaction is to mix the sugar liquid and the catalyst in the open reaction kettle and heat it to a certain temperature. While stirring, add a defoamer according to the situation. Due to the limitation of the boiling point of the liquid in this method, the temperature cannot be raised very high, and the reaction speed is limited. [0004] The closed reaction is to put the sugar solution and the catalyst in a closed reaction kettle, mix them well, heat them to a certain temperature, and keep this temperature until the end of the reaction. In the whole reaction system, only sugar solut...
