| Description: |
Orange segments in syrup, pineapple slices in syrup, mango slices in syrup, guava slices in syrup, pears in syrup, tomato juice, orange juice, mango nectar, green peas in brine, cabbage in brine and potatoes in brine were each packaged in 4 types of tinplate (Rourkela tinplate with 0.02%. 0.025% or 0.03% P and Dutch tinplate with 0.02% P, the latter being used as a control). Methods of processing and experimental results are given for all products. The canned foods were stored for periods up to 15 months at room temp. (25-28 degree C) or 37 degree C and samples and cans were examined at intervals. Quality of the products was satisfactory in all cans after 15 months storage at room temp. From results of % swelling of cans, tin content of the products, taste of product and loss in mean concavity of the cans after storage at 37 degree C, it was concluded that Roukela tinplate is suitable for canning green peas, cabbage, potatoes, tomato juice, orange juice and mango nectar, since after 12 months storage at 37 degree C, % swelling was usually very small, loss in mean concavity was negligible and the tin content of the products was generally less than the prescribed limit (250 ppm). With the other products, up to 100% swelling occurred after 12 months storage at 37 degree C, and the tin content of the products was greater than 250 ppm after 132 months storage and in some cases after 6 months. These effects were noted both in Rourkela tinplate and in controls. |
