Non blanching process of canned whole
kernel sweet corn showed more advantages than the
process with blanching. The yield in weight of the
corn kernels, drained weight, total soluble solids,
and the nutrient retention of the non-blanching
process were higher than the blanching process.
Moreover the weight of cobs which was the waste
residue was less in the non blanching process, thus
providing ease in the waste treatment.
However the blanching process has
advantage in the higher initial temperature, shorter
rate of heating and cooling, and process lethality
from which may result in the shorter thermal process
required for the product.
