Micronization is a process of heat treatment of grains using infrared radiation followed immediately by processing in an extruding-type roller mill. A laboratory model Pierce micronizer was used to process sorghum under three different temperatures: 102°, 250°, and 282°C. Sorghum processed at 250° had the highest starch availability value followed by sorghum processed at 282°C, sorghum processed at 102°, and raw sorghum. The extent of protein solubility was in decreasing order: raw, processed at 102°, processed at 250°, and processed at 282°. Increasing the temperature of the process destroyed more lysine. Animal study showed that a diet containing 15% protein from sorghum micronized at 250° and casein had a higher growth response than the diets containing raw sorghum or sorghums micronized at 102° or 282° C.
