Abstract
A method of preparing purified ester compositions is provided. The process can be utilized to isolate and purify monoglycerides and propylene glycol monoesters, to advantage. It can also be used to isolate preferred diester products. The invention also concerns equipment for conduct of the processes, provision of preferred food additives, and provision of preferred food industry compositions. The process generally involves use of liquid-liquid extractions, to advantage.
Claims13
A process for producing a crude monoglycerides mixture and for purification of monoglycerides, the process comprising steps of:
- (a) reacting a glycerol feed and a triglyceride feed in the presence of a catalyst to form a crude monoglycerides mixture;
- (b) extracting said crude monoglycerides mixture by liquid-liquid extraction to provide:
- (i) an extractant stream comprising purified monoglycerides;
- and
- (ii) a raffinate stream comprising triglycerides;
- and
- (c) recovering triglycerides from said raffinate stream to provide recovered triglycerides and adding said recovered triglycerides with said triglyceride feed.
A process for purification of monoglycerides, the process comprising steps of:
- (a) providing a crude monoglycerides mixture comprising monoglycerides, diglycerides, and triglycerides;
- (b) adding triglycerides to said crude monoglycerides mixture;
- and
- (c) extracting said crude monoglycerides mixture containing added triglycerides by liquid-liquid extraction to provide:
- (i) an extractant stream comprising purified monoglycerides;
- and
- (ii) a raffinate stream comprising triglycerides.
