Endosperm Fragmentation of Ordinary and High-Lysine Corn.

Upon treatment with isotonic buffer, the endosperm of either hand-dissected corn or selected dry-milled products---grits, meal, and flour---fragmented into fine particles that gave improved protein shifting upon air classification. Release of adhering protein from starch granules was demonstrated by optical and scanning electron microscopy. More than 50% of the total protein was shifted into two high-protein fractions by air classification of treated flours from ordinary and high-lysine corns compared to 20 to 33% for untreated flours. Protein concentrates from endosperm products of high-lysine corn have potential for use in low-cost foods. Low-protein fractions may be suitable for industrial applications.
