| 概要≠ | D-value (decimal reduction time) and Z-value characterize the thermal resistance of microorganisms in food. D-value is the time required at a specific temperature to reduce microbial population by 90% (one log unit). Z-value is the temperature change needed to reduce the D-value tenfold. Together, they enable food processors to design thermal processes ensuring microbial safety while minimizing nutrient loss. | Accelerated Shelf-Life Testing (ASLT) uses elevated temperature and controlled storage conditions to rapidly assess product degradation and predict realistic shelf-life without waiting months. By measuring quality parameters (moisture, acidity, nutrient levels, microbial growth) at accelerated conditions and applying kinetic modeling, ASLT predicts expiration dates and optimal storage parameters before market launch. |
