摘要
In vitro digestion of emulsions based two types of infant formula fat as oil phase were conducted in a simulated digestion environment of infants. Then in vitro gastric and intestinal digestibility of fat, the mean particle size, zeta potential and microstructure changes as well as the composition of free fatty acid and monoglyceride generated was measured. The results showed that the degree of gastric digestion of OPO emulsion was higher than that of control emulsion, the degree of final digestion of control emulsion was higher than OPO emulsion. The free saturated fatty acids and unsaturated fatty acid monoglyceride were generated from control emulsion were higher, while the OPO emulsion produced more free unsaturated fatty acids and saturated fatty acid monoglyceride. The average particle size and zeta potential, combined with confocal microscopic structure images proved that he positional distribution of fatty acids in triglycerides not only had an effect on the product, but also on the interfacial composition of oil droplets thus affecting its fat digestion. © 2019, Editorial Office of Journal of CIFST.
