Nutritional enrichment of common salt by calcium fortification.

IT HAS BEEN SHOWN EARLIER THAT THE
calcium present to the extent of 0-2-0.4
per cent in common salt is nutritionally availablel.
This becomes significant when it is
reckoned that the intake of salt by rice eaters
is of the order of about 25 g. per day2, and
thus the contribution of salt to dietary calcium
amounts to 50-100 mg. per day.
Since calcium is the major dietary deficiency
of the average rice eater, the fortification
of his diet with mineral supplements
rich in calcium is a prime necessity. In this
context, the idea of using common salt as a
vehicle for carrying extra calcium suggested
itself and the problem was, therefore, investigated
in detail. The results of studies on the
compatibility of different calcium salts as
enrichers to common salt without interfering
with its edible or keeping quality and
the availability of the added calcium for purposes
of growth and promoting calcium
balance have been presented in this note.
