Rapid determination of protein digestibility in sorghum before and after cooking.

Quantifying the digestibility of proteins in cereal grain is important for assessing and improving the nutritional quality of the grain after ingestion. This trait is particularly important for sorghum since the grain protein is known to be less digestible after wet cooking compared to other cereals. The reduced digestibility contributes to malnutrition in regions where sorghum is consumed as a staple food.
