Lactate made from food grade chitosan is widely used in cosmetics industry, food industry and health care industry. So, do you know how to prepare lactate from food grade chitosan? Now let's explain the gold chitosan high-density chitosan.
One of the methods for preparing lactate from food grade chitosan is to use ethanol as the reaction medium, with which chitosan and lactic acid react. Of course, the concentration, dosage, reaction time and reaction temperature of ethanol, food grade chitosan and lactic acid should be controlled.
After ethanol reacts with food grade chitosan and lactic acid for a certain time, the reactants are filtered. When the sediment and ethanol wash and precipitate to a certain extent, the chitosan lactate is obtained after drying. Gold chitosan high-density chitosan means that in the filtration step, the ethanol lactic acid solution obtained from the filtrate and washing solution should be supplemented with appropriate dosage. After the addition of lactic acid, it can be used as the reaction solution for the next batch of reactions to recycle and prepare the required chitosan lactate.
