Propylene glycol monoesters

Propylene oxide and carboxyUc acids ia equimolar ratios produce monoesters of propylene glycol. Higher ratios of oxide to acid produce polypropylene glycol monoesters. In the presence of basic catalysts these monoesters can undergo transesterification reactions that yield a product mixture of propylene glycols, monoesters, and diesters (57,60). [Pg.135]

The propylene glycol monoester can be concentrated by molecular distillation. Distilled PGME contains at least 90% monoesters, and is normally based on saturated fatty acids. [Pg.232]

Other food emulsifiers are made by transesterification of fatty acid methyl esters with poly glycerols, sorbitan, sucrose and stearoyl lactate (Figure 10.2). Sugar, sorbitan fatty esters and polyoxyethylene sorbitan esters are used to stabilize oil-in-water food emulsions. Optimum emulsification is achieved with combinations of emulsifiers. Margarines are made with a combination of monoglycerides and lecithin, and cake mixes with a mixture of monoglycerides and propylene glycol monoesters. [Pg.265]
