In the industrial production of polyglycerin fatty acid esters, since the polymerization reaction of glycerin is involved, although the reaction temperature and the polymerization degree are in a linear relationship in a direct proportion, the side reaction is increased at the same time as the temperature is increased, and the obtained polyglycerin tends to have problems of relatively dispersed polymerization degree, more branched structure and cyclic structure, heavy odor and color, and the like, and more importantly, since the polyglycerin structure in the polyglycerin fatty acid ester has many hydrophilic hydroxyl groups, the above-mentioned side reaction significantly lowers the moisturizing performance of the polyglycerin.

(2) Cooling the mixed polyglycerol, filtering, adding molecular distillation equipment for molecular distillation to remove unreacted glycerol, and distilling out polyglycerol.
(3) Mixing and stirring the polyglycerin steamed out in the step (2) and a polyglycerin fatty acid ester emulsifier; the polyglyceryl fatty acid ester emulsifier is S-Face L-1001 and S-Face M-1001.
(4) Adding liquid fatty acid into a reaction kettle, adding the polyglycerol obtained in the step (3), adding a catalyst, stirring and heating, and reacting under a vacuum condition to obtain the polyglycerol fatty acid ester; stirring and heating to 150-200 ℃ for reaction, wherein the vacuum degree is 0.05-0.08Mpa, and the reaction time is 1.5-3 hours.
Wherein the solid base catalyst is an alumina supported solid base catalyst containing SnCl 2. Under the catalysis of a solid base catalyst, the polymerization degree of polyglycerol generated by polymerization reaction of glycerol is concentrated and takes a straight chain structure as a main part, the polymerization reaction temperature can be about 20 ℃ lower than that of the conventional process, and the polymerization reaction temperature and time can be controlled according to the requirement on the polymerization degree of the polyglycerol so as to improve the content of target polyglycerol in the mixed polyglycerol, thereby not only reducing the production cost, but also reducing the problems of more branched chain structures and cyclic structures, heavier odor and color and the like of the polyglycerol caused by high-temperature polymerization, and reducing the separation difficulty of molecular distillation; compared with the traditional process, the polyglycerol fatty acid ester produced by the preparation method has better quality, lighter smell and lighter color, can reach the same level of imported products, meets the national food additive safety standard, has stronger emulsifying capacity, and is suitable for the performance requirements and food safety requirements of various emulsifying systems.

When the molar ratio of the fatty acid to the polyglycerol is less than 1.1:1, the polyglycerol cannot be fully subjected to esterification reaction, so that the content of the polyglycerol in an esterification reaction product is high, and the purity of polyglycerol fatty acid ester is low; when the molar ratio of fatty acid to polyglycerin is more than 1.3:1, the fatty acid is excessive, and the purity of polyglycerin fatty acid ester in the esterification reaction product is also low.

The invention has the following advantages and beneficial effects:
1. the preparation method of the polyglycerol fatty acid ester can control the temperature and time of polymerization reaction according to the requirement on the polymerization degree of the polyglycerol so as to improve the content of target polyglycerol in the mixed polyglycerol, and the obtained polyglycerol mainly has a linear chain structure.
2. The preparation method of the polyglycerol fatty acid ester provided by the invention adds the polyglycerol fatty acid ester emulsifier, and the moisturizing performance of the polyglycerol is obviously improved by adding the emulsifier.
