| Abstract | Spray-dried cereal extracts containing probiotic Lactobacillus plantarum TISTR 2075 was produced. Sterile soya milk extract and Job's-tears extract fortified with sesame (1-2%) and glucose (1-20%) were fermented by L. plantarum TISTR 2075. After 24 hr, the strain was found to grow well both in soya milk and Job's-tears extracts with viable cells of 8.28 and 7.73 log CFU/mL respectively. Higher viable cells were observed with addition of 1% glucose and 1% sesame. Sesame was also found to significantly increase soluble calcium after fermentation due to lowered pH due to the production of organic acids. Each fermented cereal extract was then mixed with 20% maltodextrin prior to spray-drying at 130?C and 70?C (inlet and outlet air temperature respectively). After spray-drying, the survival of L. plantarum TISTR 2075 in spray-dried soya milk and Job's-tears extract powders was 79.0 and 85.4% respectively. The functional properties of the probiotic including pathogenic inhibition of foodborne pathogens (Escherichia coli O157:H7 DMST 12743 and Salmonella typhimurium ATCC 13311) and the tolerance to simulated gastric juice (pH 2.0) and small intestinal juice (pH 8.0) were not affected by the spray-drying process. |
