The thermal treatment was evaluated based on load of aerobic mesófilos expressed in ufc/ml, with this results it was determined at laboratory level the securities of the Decimal Reduction Time (D): D80=15481,039s, D90 = 2274,052, D100 = 333,857s and Thermal Resistance Constant (z) = 12 °C. By means of lineal regression the value D139 was calculated = 0,185s; finally the value of the Thermal Death Time was determined (F139) = 4,1s. With the securities F and obtained z milk was processed in the Sterilizer Tetra Therm® Aseptic Flex - Tetra Pack…. |
