Problems solved by technology

However, because rosin has not removed trace metal elements in the preparation process, the raw material rosin bought from the market generally contains high trace metal elements such as aluminum, and these trace metal elements are too high to cause brain damage and memory loss , senile dementia and other consequences, this is a relatively sensitive impurity that affects the application of rosin in food additives with extremely strict requirements
If these rosins containing high trace metal elements such as aluminum are used as one of the raw materials to prepare rosin acid sucrose ester, the obtained product contains trace metal elements such as aluminum must also be high, which will make its product abietic acid Sucrose esters cannot meet the requirements of food additive standards

Abstract

The invention discloses a method for preparing sucrose abietate and belongs to the field of preparation of surfactants. The method comprises the following steps: by taking rosin as a raw material, removing aluminum and other trace metal elements in the process of preparing refined rosin from the rosin, and reacting the rosin with sucrose under the catalytic action of a catalyst. The method is simple in operation and mild in reaction conditions, the content of aluminum and other trace metal elements in the product sucrose abietate is effectively reduced, and damage to a human body is avoided.

Description

technical field [0001] The invention belongs to the field of surfactant preparation, in particular to a method for preparing rosin acid sucrose ester. Background technique [0002] Sucrose rosinate is a kind of surfactant with good biodegradability, which can be used as emulsifier, dispersant and viscosity regulator of food. It is mainly prepared from rosin and sucrose as the main raw materials. However, because rosin has not removed trace metal elements in the preparation process, the raw material rosin bought from the market generally contains high trace metal elements such as aluminum, and these trace metal elements are too high to cause brain damage and memory loss , senile dementia and other consequences, this is a relatively sensitive impurity that affects the application of rosin in food additives with extremely strict requirements. If these rosins containing high trace metal elements such as aluminum are used as one of the raw materials to prepare rosin acid sucros...
