Studies on dry-salting and sun-drying of mackerel (Rastrelliger kanagurta Cuv.). II. Effect of chlortetracycline, sorbic acid, sodium propionate, sodium benzoate, and sodium acid phosphate on the keeping quality of sun-dried salted mackerel.

The present study was undertaken to follow
the deteriorative changes that take place when
market samples of sun-dried salted mackerels are
kept stored as such and next to find out the efficacy
of certain bacteriostatic arid fungicidal subs
tances on the keeping quality of sun-dried
mackerel.
Chlortetracycline as bacteriostatic agent, sorbic
acid and sodium propionate as fungicidal agent,
were tried. A mixture of sodium benzoate and
sodium acid phosphate which have been reported
to be highly effective in checking the growth of
red~halophils was also tried.
