Description Finger millet seed coat matter (SCM) is a rich source of dietary fiber, calcium, iron and zinc (Zn). However,
the bioavailability of minerals especially Zn is limited as it occurs as insoluble complexes with phytate.
This study envisages the potential of phytase-active Lactobacillus pentosus CFR3 to dephytinize SCM
derived from native (non-processed), malted and hydrothermally treated finger millets with an expectation
to improve its Zn bioavailability. After 24 h fermentation, the phytate in native, malted and hydrothermally
treated SCM reduced to 56.70%, 66.65% and 87.85% respectively. Correspondingly, Phytate/
Zn molar ratios decreased to 18.20, 19.20 and 22.32 indicating improved Zn bioavailability. Also, Zn
bioaccessibility from native, malted and hydrothermally treated SCM increased to 28.40%, 34.57% and
12.10% as determined by in vitro dialyzability experiments following 24 h fermentation. Therefore,
fermentation of SCM with L. pentosus CFR3 represents a safe and feasible solution to counteract the
effects of phytate on Zn absorption.
