Summary Corrosion performance in citrus fruit juices of five different batches of electrolytic tinplates having values of special properties test outside of type K tinplate specifications was studied. The effect of A.T.C. values was followed in order to find out the precise limits for an adequate shelf life in citrus fruit juice packs. The effect of different levels of nitrate and sulphur dioxide in relating with A.T.C. values was investigated. It was shown that (1) certain A.T.C. values are necessary in order to obtain a good shelf life in pure juices and those values are different for orange and grapefruit juices; (2) while the A.T.C. value can affect the detinning rate in pure citrus juices, the addition of nitrate and sulphur dioxide at concentrations used, overrides this effect.
