Notes:
Chemical changes caused by heating in a continuous flow, helically coiled tube indirect UHT process system were evaluated and compared to a nonflow vat process system. A computerized procedure was developed to estimate the rates (R) and accumulated values (Fc) of chemical changes in the various stages of the UHT and vat thermal processes. The procedure could also be used to determine the conditions necessary to optimize quality and/or nutrient retention. Data were based on 300°F and 3.3 set holding time in the continuous process and 180°F for 30 min holding time in the vat system, Approximately 10% of the overall chemical changes occurred during the heating period for both processes, 88% and 87% during the holding periods, and 2% and 6% during the cooling respectively for the UHT and vat processes.
