Sažetak
L-Tryptophan is precursor of some indole glucosinolates, compounds of thioglucosidic structure present in cruciferous vegetables. These natural compounds are components of everyday human diet and exert some beneficial effects on human health. Tin and aluminium are standard ambalage materials used in canned food industry. They can give, by interactions with some food components, other products with sometimes harmful effects on human health. Therefore, the usage of natural compounds as possible metal corrosion inhibitors gains nowdays more attention. The aim of this study was the examination of L-tryptophan and glucosinolates extracts on tin and aluminium behaviour in 3 % solution of sodium chloride. This system was chosen to investigate the corrosion process that could take place in canned vegetable products with these compounds as ingredients, tin and aluminium being ambalage materials. The physico-chemical and corrosion parametars of tin and aluminium were determined in model solutions by electrochemical methods (potentiostatic polarization and polarization resistance method). The results obtained by both methods indicated that L-tryptophan as well as glucosinolates extracts acted as corrosion inhibitors of tin and aluminium. The inhibition efficiency values were higher for both metals in L-tryptophan solutions compared to values in glucosinolates extracts. Also, the inhibition efficiency values were higher in more diluted solutions.
