As per FSS Regulations, in canned rasgulla the maximum permissible level of tin is 250 mg/kg by weight. Tin is used principally in the production of coatings used in the food industry. Food, particularly canned food, therefore represents the major route of human exposure to tin. The main adverse effect on humans of excessive levels of tin in canned beverages or canned foods is acute gastric irritation. Excessive intake of tin can cause vomiting, diarrhoea, fatigue, and headache.
