Protein content, in-vitro protein digestibility (IVPD)‎, anti-nutritional factor and mineral content and bioavailability of sixteen sweet sorghum (Sorghum bicolor L Moench)‎ grain genotypes grown in Sudan

Abstract EN

The objective of this study was to evaluate the protein content, in vitro protein digestibility (IVPD), tannin content, phytic acid content, total polyphenol content and total and bioavailability of minerals of sixteen genotypes of sweet sorghum grains grown in Sudan.

The protein content of the samples ranged from a high of 15.1% for S6 genotype to a low of 6.0% for AD13 genotype.

The IVPD investigation showed that there was no significant differences among the most of the genotypes, except AD7, ADS26 and ADS16 which revealed the lower values of the IVPD.

Most of the sweet sorghum genotypes contain low levels of antinutritional factors.

The profile of mineral content and bioavailability indicated that sweet sorghum grains are rich source of essential minerals with high bioavailability rate.

These, results showed that sweet sorghum grains from different genotypes have the potentiality to develop new value-added products for grains biofortification.
