Biocompatible Food Matrix for Digestibility and Bioavailability of β-Carotene, Resveratrol, and Gypenosides.

Summary

This study investigated how co-ingested food matrices influence the bioaccessibility and potential bioavailability of three bioactive compounds — β-carotene, resveratrol, and gypenosides — using standardised in vitro digestion models. A range of carriers were evaluated, including coffee, water, yogurt, bread with sauce, and fruit/vegetable juices and smoothies, revealing substantial variation in bioactive compound uptake depending on the matrix. The findings suggest that matrix composition meaningfully modulates absorption potential, with implications for dietary guidance on consuming phytonutrient-rich foods and supplements.

UK applicability

Although the study does not appear to be conducted specifically in a UK context, its findings are broadly applicable to UK dietary patterns, particularly given widespread consumption of the tested food matrices such as coffee, yogurt, and fruit juices. The results may inform UK public health guidance on optimising bioactive compound absorption from functional foods and dietary supplements.

Key measures

In vitro digestibility (%); potential bioavailability (%); micelle formation; bioactive compound uptake across food matrices (β-carotene, resveratrol, gypenosides)

Outcomes reported

The study measured in vitro digestibility and potential bioavailability of β-carotene, resveratrol, and gypenosides across a range of food matrix carriers including liquids, dairy products, solid foods, and fruit/vegetable-based preparations. It reported percentage uptake values for each bioactive compound across the different matrices.
