Abstract

The invention discloses a preparation method of self-emulsifying glycerol monolaurate, comprising the following steps of a, respectively weighing glycerol monolaurate, an emulgator, a solubilizer, anemulsion stabilizer and a carrier; b, heating the glycerol monolaurate to 40 to 60 DEG C, then adding the emulgator and dissolving to obtain an oil phase; c, adding the emulsion stabilizer into water,heating to 40 to 60 DEG C for dissolving to obtain a water phase for later use; d, adding the oil phase solution obtained in the step b into the water phase solution obtained in the step c, stirringand homogenizing to ontain a glycerol monolaurate solution; e, cooling the solution obtained in the step d to room temperature, adding the solubilizer, performing secondary homogenization to obtain asemitransparent or transparent solution; f, mixing the solution obtained in the step e with the carrier, and performing spray drying to prepare solid particles. The self-emulsifying glycerol monolaurate prepared by the invention has the advantages that a self-emulsifying solution is adsorbed by the carrier, the fluidity is good, moisture absorption is not easy to occur, the use is convenient, andthe uniform mixing of a feed is facilitated.

Description

technical field [0001] The invention belongs to the technical field, in particular to a preparation method of self-emulsifying monoglyceride laurate. Background technique [0002] Monolauric acid monoglyceride, also known as monolauric acid monoglyceride, is a lipophilic nonionic surfactant that naturally occurs in breast milk and American palmflower. Monolauric acid monoglyceride is synthesized by direct esterification of lauric acid and glycerin. The appearance is generally scaly or oily, white or light yellow fine-grained crystals. The freezing point is 46-55 degrees. It is an excellent food emulsifier, and the HLB value is 5.2, it is also an internationally recognized safe, efficient, and broad-spectrum bacteriostatic agent, which has a strong effect on common bacteria, molds, and yeasts in food, and also has the effect of inhibiting various viruses and protozoa. Its antibacterial effect is not affected by pH, and is superior to potassium sorbate, sodium benzoate, sodiu...
