Obtaining surfactants by transesterification of glyceryl esters of lactic acid with triacylglycerol

Obtaining surfactants by transesterification of glyceryl esters of lactic acid with triacylglycerol

Abstract

Despite the widespread use of food surfactants, the existing technologies for their production are complex, multistep and energy intensive. Moreover, today in Ukraine there are no enterprises that could produce mono- and diacylglycerols independently, so the domestic food industry enterprises have to buy food surfuctants abroad.The possibility of obtaining food surfuctants, namely lactic acid esters, mono- and diacylglycerols, during the two-step process: the esterification of lactic acid with glycerol, followed by the transesterification of the obtained esters with triacylglycerols, is considered in the paper. The kinetics of the reaction behavior of the glycerol esterification with lactic acid by acid and ester numbers is presented, as well as a comparative characteristic of the emulsifying ability of the obtained product with industrial monoacylglycerols is given. The described method allows obtaining a food emulsifier with high surface-active properties.

В статье рассмотрена возможность получения пищевых поверхностно-активных веществ, а именно эфиров молочной кислоты и моно-, диацилглицеролов, в ходе двухстадийного процесса: этерификации глицерола молочной кислотой с последующей переэтерификацией полученных эфиров с триацилглицеролами. Также исследованы поверхностно-активные свойства полученного продукта в сравнении с промышленным эмульгатором.

У статті розглянута можливість одержання поверхнево-активних речовин, а саме ефірів молочної кислоти з моно-, діацилгліцеролами, в ході двустадійного процесу: етерифікації гліцеролу молочною кислотою з наступною переетерифікацією одержаних ефірів з триацилгліцеролами. Також досліджені поверхнево-активні властивості одержаного продукту в порівнянні з промисловим емульгатором.
