Consumer Advice ​

Stannous chloride is a tin salt used in canned fruit and vegetables as an antioxidant and colour-protecting agent to prevent browning and metallic off-flavours. Its use is strictly limited, with a JECFA acceptable daily intake. Normal consumption is safe; large amounts of tin can irritate the stomach, so regulators enforce tight residue limits and consumers need not be concerned.
