Abstract

The invention relates to a production process of polyglycerol fatty acid ester, belonging to the field of emulsifier preparation. The purpose of the present invention is to overcome the defects of the prior art and provide a production process for polyglycerol fatty acid esters. In this process, high-quality polyglycerol fatty acid esters are synthesized by rationally selecting catalysts and a two-stage method. The reaction conditions of the method are mild and easy. Control, the product color is obviously improved, no peculiar smell, less impurities, reasonable structure, excellent performance, and environmentally friendly, no three wastes discharge.

Description

technical field [0001] The invention relates to a production process of polyglycerol fatty acid ester, belonging to the field of emulsifier preparation. Background technique [0002] Polyglyceryl fatty acid ester is a non-ionic surfactant, referred to as PGFE. Polyglyceryl ester has both hydrophilic and lipophilic properties, has a high HLB value, and has multiple properties such as good emulsification, dispersion, wetting, stability, and foaming. It is easily soluble in oil, ethanol and organic solvents, and can be dispersed in hot water. It can be decomposed in the process of human metabolism, so as to participate in metabolism and be utilized by the human body. It is highly safe and is a kind of high-efficiency and safe additive. It is recommended by the Food and Agriculture Organization of the United Nations and the World Health Organization (FAO / WHO). At the same time, polyglycerol esters are quite stable in acidic, alkaline and neutral environments, and have good emul...
