Investigation On The Factors Impacting The Bioaccessibility Of Oil-Soluble Vitamins: Food Matrix Effects, Yunbing Tan

Doctoral Dissertations

Food, nutrition, and pharmaceutical scientists are trying to elucidate the major factors impacting the bioavailability of macronutrients (e.g., lipids), micronutrients (e.g., vitamins), and nutraceuticals (e.g., carotenoids) so as to improve their efficacy. Currently, however, there is a limited understanding of how food matrix effects impact nutrient digestion and bioavailability. In this thesis, the impact of food matrix effects was elucidated by systematically examining the influence of several important factors (including oil type, oil concentration, droplet size, emulsifier type, and nutrient type) on lipid digestion and the bioaccessibility of hydrophobic bioactive agents. Oil-in-water emulsions were used as model …
