Effects of pretreatments on yield and qualities of canned whole kernel sweet corn were studied Average yield, drained weight, pH, total soluble solids, and the heating and cooling parameters were determined. The processed canned samples were analyzed for nutrients. It was found that non-blanching process showed more advantages than the process with blanching. The average of yield of the corn kernels, drained weight, total soluble solids, and the nutrient retention of the non-blanching process were higher than the process with blanching, while the weight of the waste residue was lower. However the blanching process has advantage in resulting higher initial temperature (It), shorter rate of heating (fh), rate of cooling (fc) and process lethality at the geometrical center of the can (Fc) from which may result in the shorter thermal process required for the product.
