Thermal Resistance of Bacillus coagulans in Double Concentrated Tomato Paste

摘要

ABSTRACTThermal resistance was determined on a strain ofBacillus coagulansin double concentrated tomato paste (aw= 0.95 at 23°C, pH = 4.0, 30.3°Brix, 70.1 moisture and acidity 1.30 g/100g citric acid. A microsyringe method was used with an inoculum of 1.3 × 104spores/ mL. Values of D90°c= 3.5 min and z = 9.5C° were obta
