A modified ben-saalga composed of แป้งสาคู millet-groundnut blend was prepared according to the method described by Tou and al (2007). แป้งสาคู millet and groundnut are blended in the proportions of 76 and 24 % (DM) in order to obtain 250g (dry weight -d.w.-). The blend was first soaked in water (1:1.5 w/w) for 16 h, washed with water (1:2 w/w), and drained for 30 min. It is then milled for 3 min using a laboratory blender (ผสม) sieved with water (1:3.5 w/w) through a 0.710mm sieve and boiled for 10 min, then cooled around 35°C before การใส่เชื้อ with a starter การเพาะเชื้อ of lactic acid bacteria (1-2%, v/w) or by back slopping (3%,w/w), a small amount of fermented paste from a previous successful fermentation used as inoculum. A negative control was made by natural fermentation without precooking like in the traditional process. After 24 h fermentation, the porridge was prepared by diluting fermented paste in water and boiling for 5 min. The experiments were done in triplicate for each condition of fermentation.
