Food additive: Preparation method of propylene glycol fatty acid ester

The preparation of propylene glycol fatty acid esters uses propylene glycol and fatty acids as raw materials, with esterification occurring under alkaline catalysis within an appropriate temperature range. During the reaction, close monitoring of esterification degree and reaction rate is required to ensure the product reaches the desired esterification level. After completion, neutralization removes the catalyst, followed by washing with water to remove unreacted raw materials and generated salts, and finally drying to obtain pure propylene glycol fatty acid esters. This method is mature, producing a product with good stability and solubility.
