Removal of fatty acid from esterified propoxylated glycerin

摘要

An esterified propoxylated glycerin process is improved by the incorporation of a vacuum distillation step whereby unreacted fatty acids are removed in a form suitable for direct reuse in a further esterification. The esterified propoxylated glycerin produced is low in color and has a low content of free fatty acid, making it suitable for use as a reduced calorie fat substitute in various food products.
