Abstract

The invention discloses a preparation method of pale rosin glyceryl ester. The preparation method comprises the following steps: under the protection of inert gas, heating to dissolve rosin, adding glycerol, a catalyst and a water-carrying agent, adding a C4+ olefin solution into the reaction kettle, stirring uniformly, and gradually heating to react; and stopping introducing the inert gas, filtering to remove the catalyst, removing the impurity liquid, and collecting the product. The rosin glycerol product has the advantages of light color, high softening point and favorable crystallization resistance.

Description

technical field [0001] The invention relates to the technical field of rosin deep processing, in particular to a preparation method of light-colored rosin glyceride. Background technique [0002] Rosin glyceride, also known as ester gum, hydrogenated ester gum and glycerol triabietate. There is no clear chemical structure formula, the main component is abietic acid triglyceride, and a small amount of abietic acid diglyceride and monoglyceride, it can be used as a base material in gum-based candies, food flavors, and processing aids in the food industry Wait. [0003] Compared with rosin, rosin glyceride has a lower color value, significantly lower acid value, less brittleness and stickiness, improved weather resistance, and no longer has a corrosive effect on metals. But the performance of rosin glyceride still needs to be improved. Contents of the invention [0004] The purpose of the present invention is to provide a kind of preparation method of light-colored rosin g...
