摘要：
The digestion of β-carotene nanoemulsion prepared by ultrasonic and high pressure homogenization was studied by in vitro simulated digestion. The results showed that the average particle size of the β-carotene nanoemulsion prepared by the two methods was significantly increased during gastric digestion (P<0.05), which was related to the enzymatic hydrolysis of some soybean protein adsorbed at the interface of the emulsion. The average particle size and turbidity of the two kinds of nanoemulsion were decreased and the ζ potential was negative increased. After gastrointestinal digestion, the release rate of FFAs was significantly higher than that of β-carotene dissolved in oil phase, and all of them were more than 100%, indicating that phosphatidylcholine and oil phase were digested during the intestinal digestion. The bioavailability of nanoemulsion prepared by ultrasonic was higher than that of high pressure homogenization. © 2018, Editorial Office of Journal of CIFST. All right reserved.
