example 1

[0005] The production method of calcium stearoyl lactate stabilizer, the main steps are: adding lactic acid into the reactor, reducing pressure to 30kPa, dehydrating at 90℃ for 90min, then adding stearic acid and calcium carbonate to the reactor, and then Under the protection of inert gas nitrogen, the temperature is kept at 130℃, and the esterification reaction is carried out for 2h. The material is decolorized and cooled, washed with dichloromethane solution for 80min, recrystallized in ethyl acetate solution, dehydrated by dehydrating agent to obtain the finished product, among which, dichloromethane solution The mass fraction is 30%, and the mass fraction of ethyl acetate solution is 50%.

[0009] The production method of calcium sodium stearoyl lactate stabilizer, the main steps are: add lactic acid to the reactor, reduce pressure to 33kPa, dehydration reaction at 96℃ for 120min, then add stearic acid and calcium carbonate to the reactor, and then Under the protection of inert gas nitrogen, the temperature is kept at 140°C, and the esterification reaction is carried out for 3 hours. The material is decolorized and cooled, washed with dichloromethane solution for 100 minutes, recrystallized in ethyl acetate solution, dehydrated by dehydrating agent, and the finished product is obtained. The mass fraction is 34%, and the mass fraction of ethyl acetate solution is 55%.

Abstract

The invention discloses a production method of a sodium stearoyl lactylate stabilizer. The production method mainly comprises the following steps of adding lactic acid in a reactor, performing decompression to 30-33kPa, performing dehydration reaction for 90-120mins under the condition with the temperature being 90-96 DEG C, then adding stearic acid and calcium carbonate in the reactor, performingthermal insulation at 130-140 DEG C under inert gas nitrogen protection, performing esterification reaction for 2-3h, performing decoloration and cooling on a material, washing the material with a dichloromethane solution for 80-100mins, performing recrystallization in an ethyl acetate solution, and performing dehydration with a dehydrating agent to obtain a finished product.

Description

Technical field [0001] The present invention relates to a method for producing compounds, in particular to a method for producing calcium sodium stearoyl lactate stabilizer. Background technique [0002] Calcium stearoyl lactate is mainly used as a dough regulator, stabilizer, emulsifier, foaming agent, and also as a bread quality improver. The addition amount is 0.5% of wheat flour, which can improve the kneading resistance of the dough and increase the softness of the bread , The maximum dosage for dry protein foaming agent is 0.5%, and the dosage for liquid and frozen protein is less than 0.05%. Most of the existing production methods are relatively complicated, and calcium sodium stearoyl lactate is used as a stabilizer. The pros and cons of the production methods have important economic significance for improving product quality and reducing by-product content. Summary of the invention [0003] The purpose of the present invention is to provide a method for producing calcium...
