![]() ![]() Highly significant ( P ≤ 0.01) correlations were obtained between TPC (total plate count) and SI (sensory index) (r = −0.94 to −0.97), coliforms and SI (r = −0.89 to −0.95), and LAB (lactic acid bacteria) and SI (r = −0.93 to −0.98). Mean Kinetic Temperature - Excel Help Forum. However, only the microbiological spoilage regarding TPC, whose values ranged from 7.0 to 8.0 log CFU/g under all investigated temperature conditions, were in compliance with the end of sensory shelf-life defined at SI = 5. Details: 1) calculate k at each temperature in an adjacent column. 2) use the AVERAGE () function on this column to get the average k. 3) Algebraically rearrange the Arrhenius equation to get T at k, and use that formula in Excel to get the mean kinetic temperature. To develop dynamic quality prediction model, 4 isothermal (0, 4, 10, and 15☌) experiments in 2 batches were performed for TPC evaluation. ![]() Growth data were fitted in the Baranyi and Roberts and quadratic polynomial model as the primary and secondary models, respectively. The model was validated under dynamic conditions (0–8☌ scenario with periodic 12-h changes). The accuracy and bias factors were estimated to be 1.045 and 0.991 for fluctuating conditions and 1.016 and 1.015 for real-time conditions, respectively, suggesting good applicability of the model. The remaining shelf-life estimation model developed based on mean kinetic temperature showed an even decrease of shelf-life under dynamic conditions in time.
