Abstract
Ivy gourd canned in plain, acid resistant (AR) and sulphur resistant (SR) lacquered cans made from either hot dip (HD) or electrolytic (E) tinplate caused complete detinning in 14 wk except in lacquered cans. SR lacquered cans cannot be used below pH 5.5 because of leaching of Zn. Pieces of tinplate cans were used to study the corrosive properties of the alcohol-soluble fraction, organic acids and phenolic compounds from ivy gourd. It is concluded that the anionic constituents of ivy gourd, such as citric, malic and succinic acids, and phenolic compounds are responsible for detinning. Results are discussed.
