Description Four common acidulants in Indian dietary, i. e., citric acid, tamarind (Tamarindus indica), amchur
(Mangifera indica), and kokum (Garcinia indica) were examined for a possible influence on the bioaccessibility
of zinc from selected food grains. Among the four acidulants examined, amchur and
citric acid generally enhanced the bioaccessibility of zinc and iron from all the food grains studied.
The increase in zinc bioaccessibility produced by citric acid was around 40% in rice and chickpea,
while amchur produced around 60% increase from decorticated green gram. This positive influence
of acidulants on zinc bioaccessibility from food grains was seen both in the raw and cooked form.
Tamarind and kokum, the other two acidulants tested, generally did not have a favourable influence
on zinc and iron bioaccessibility. This lack of positive influence of these two acidulants on mineral
availability could be attributable to the presence of significant amounts of tannin in them. Citric acid
and amchur also generally enhanced the bioaccessibility of iron from these food grains.
