The practice of boiling milk in the home, common in many tropical countries, leads to losses of vitamin A which are more serious with reconstituted than with fresh milk. Losses ranged from 2 to 20 per cent after 2 minutes' boiling of milk reconstituted from vitamin A fortified non-fat milk powder, and rose to 30 per cent after 30 minutes heating.
