1,3-Dioleoyl-2-palmitoylglycerol-rich triacylglycerol characterization by three processing methods
1,3-Dioleoyl-2-palmitoylglycerol (OPO) is a kind of structured triglyceride which could instead human milk fat (HMF) for the fat of infant formula, this kind of structured triglyceride is good at absorbing easily. The aim of this paper was to produce OPO though three different processing technologie...
