This study developed a new in vitro human digestion model to simulate the digestion of vitamin E emulsified with lard in adults and elderly individuals, showing significant differences in digestibility between age groups. The model accurately simulates the oral, gastric, and intestinal digestion of bioactive substances and can assist in drug delivery analysis for adults and elderly individuals.
In vitro human digestion models are widely used to determine the digestibility of bioactive substances and to perform drug delivery analyses. To develop the most accurate in vitro human digestion model reported to date, we simulated all digestion conditions, including pH and digestion time, with changes in the amount of digestive enzymes, motility, and proportion of human gut microbiota in adult and elderly individuals. Using this newly developed model, the digestibility of vitamin E emulsified by lard was found to be significantly different between adults and the elderly. Therefore, this model can accurately simulate oral, gastric, and intestinal (with gut microbiota effects) digestion of bioactive substances and can aid in analyzing drug delivery in adults and elderly individuals.
