Study on bioavailability of Fe-enriched wheat varieties using an in vitro digestion/Caco-2 cell model

Abstract

OBJECTIVE: To select the most promising Fe-enriched wheat varieties by studying Fe bioavailability from several wheat variety flours so as to provide scientific evidence for further human trials and nutrition targets in wheat breeding. METHODS: The Fe bioavailability among 10 Fe-enriched wheat flours was assessed using an in vitro/Caco-2 cell culture model. Caco-2 cell ferritin formation was measured as an indicator of Fe utilized by human Caco-2 exposing to tested flour digests. RESULTS: Significant differences were detected in Fe bioavailability among 10 flour varieties, Zhongyou 9507 (from Anyang) and Jingdong 8 with 78% flour yield had the highest Fe bioavailability. CONCLUSION: The two most promising varieties, Zhongyou 9507 (from Anyang) and Jingdong 8 will be further evaluated in human trials to determine their efficacy
