Corrosion of tinplate by citrus juices

Abstract

Summary Juice from the Satsuma Mandarin variety of oranges which was free from bitterness with less acidity gave more corrosion as compared with the juice from Coorg Mandarin, Mandarin Imperial, Tangerine Dancy and Washington Navel. Bitter principles present in the orange juice were found to act as inhibitors of corrosion. Limonin acted as inhibitor of corrosion, while hesperidin did not show any effect. Among different fractions of orange juice, the organic acid fraction contributed towards corrosion.
