Increasing wheat flour consumption makes increasing of wheat import value in Indonesia. Wheat flour has good nutritions, sufficient gluten compound, high glucose and high glycemic index. Therefore, substituting wheat with sorghum (local crop) which has gluten free, a low glucose and glycemic index value, can overcome food security problem in Indonesia. However, it has a high phytic acid and tannin (antinutrients). This study focuses on the reduction of antinutrients by three processes (fermentation treatment using lactic acid bacterias (LAB), including Lactobacillus bulgaricuss, Lactobacillus casei, and Lactobacillus brevis (1); NaOH solution submersion (2); and combining NaOH solution submersion followed by fermentation (3)). It was found that combining NaOH solution submersion and fermentation resulted in reduction of antinutrient contents (phytic acid decreased from 11.9% to 0.117% and the tannin decreased from 6.16% to 0.063%) and improved nutrition composition (such as protein content increased from 8.59% to 14.67%) on sorghum so that sorghum could be feasible to be an alternative source of wheat substitution in flour production. Moreover, the glucose content and glycemic Index (GI) of modified sorghum flour was decreased from 2.75 to 1.83%, and decreased from 40.79 to 36.33, respectively.
