Intact or Unit-Kernel Sweet Corn

摘要

This report evaluates process and product modifications in canned and frozen sweet corn manufacture with the objective of reducing the total effluent produced in processing. In particular it evaluates the proposed replacement of process steps that yield cut or whole kernel corn with process steps that yield intact or unit kernel corn. When compared to a conventional cutting process with a yield of 40 to 33 parts per 100 parts of corn in husk, the processing of intact kernels resulted in corresponding waste reductions of 85% to 94% (based on chemical oxygen demand per pound of product) and yield increases of 5% to 26%. Sensory comparisons showed that regardless of the variety or method of preservation, intact kernel samples were preferred by a larger percentage of the panel (paired preference rating) than the cut controls.
