Formulation and characterization of dry mixes based on dehydrated fresh high-lysine corn.

Fresh sweet corn pulp from high-lysine corn was dehydrated in a drum-dryer and utilized in the formulation of creamy instant soups. Studied formulas contained 27.5 to 67% dehydrated high-lysine corn pulp. The sensory profiles of the formulas improved with increasing proportion of dehydrated fresh corn pulp. Formula with 27.5% fresh corn pulp was rated lowest by the tasters on the basis of poor appearance, low characteristic fresh corn flavor and low overall impression. Formulas with 60 and 67% corn pulp rated highest in sensory quality and were nutritionally adequate. The PER for these formulas did not differ from casein control diet but nitrogen absorption and nitrogen retention was inferior for the formulas protein as compared to casein.
