Biochemical Changes during Traditional Fermentation of Saudi Sorghum (Sorghum bicolor L.) Cultivars Flour into Khamir (Local Gluten Free Bread).

Effect of traditional fermentation on pH, titratable acidity, proteins, amino acids, and sugars contents of three local sorghum cultivars namely Hamra, Biadah and Shahla used in making khamir local bread were investigated. During 24 fermentations, the pH of fermented dough dropped sharply and this was coincided with increase in total acidity. Fermentation was found to cause no significant change in protein content of the cultivars.
