EDIBLE SALT IS: 253-1985
|
|
Specification is prescribed for common salt, table salt and dairy salt. Table salt
and dairy salt is refined common salt coated with permitted anti-caking agents.
Dairy salt is a refined common salt obtained by forced evaporated of treated brine.
The moisture content shall not be more than 6 % in respect of common salt and 0.5
% in respect of table and dairy salt.
The other important characteristic for common salt is that material shell be crystalline
white solid. Common salt produced by solar evaporation may not contain anti-caking
Agent.
