γ-Aminobutyric acid (GABA) is present in many vegetables and fruits, but not in dairy products. GABA is known to be beneficial for preventing neurological disorders and hypertension. The objective of this study was to measure the physicochemical changes, number of lactic acid bacteria, and GABA content in fermented goat milk containing rice (1%). The levels of pH and titratable acidity (TA) in each test samples were found to be pH 4.4∼4.5 and 0.74∼0.8%, respectively. The number of viable lactic acid bacteria between test samples ranged from 8.63 to 8.95 Log CFU/ml. Therefore, pH, TA, and number of viable cells in each test sample had no difference. Furthermore, the Lactobacillus delbrueckii subsp. bulgaricus SP5 (Lb. bulgaricus SP5) showed the highest GABA production in goat milk containing rice. Its maximum GABA yield was 3.4 mg/100 mL. The results suggest that GABA contents of fermented goat milk containing rice can be enriched using Lb. bulgaricus SP5.
