Popis: |
A new time–temperature integrator (TTI) for the measurement of mild pasteurisation treatments is described. The objective was to measure thermal processes of the order of a few minutes at 70 °C. Food products that receive these treatments are intended for sale either under refrigerated conditions with Bacillus amyloliquefaciens in 10 mM acetate buffer. Decimal reduction time ( D 70 -value) of 8.4 min and z -value of 8.9 C° were calculated for BAA70 in a water bath. Maximum P -values measured with BAA70 were up to 25.2 min at 70 °C. Industrial evaluation for surface pasteurisation in hot-filled mini jam jars and for continuous oven cooking of quiches demonstrated the applicability of the BAA70 TTI. P -Values in both these operations could not be measured using conventional temperature sensors and so the TTIs provided invaluable data on pasteurisation achieved. |
