Inspection of the setting of expiration dates and best-before dates for food ingredients and products.

Expiration Date Setting Test The expiration date indicates the period during which food can be safely consumed, typically focusing on perishable ingredients and showing a short duration of a few days to a few weeks. It is often determined based on the proliferation of microorganisms. Best Before Date Setting Test The best before date indicates the period during which food can be enjoyed at its best quality, usually focusing on shelf-stable ingredients and showing a longer duration of a few weeks to several years. It is often determined based on indicators such as water activity, oil acidity, and the denaturation of components like proteins. Accelerated Testing; When setting the best before date, conducting tests over a long period can often be impractical, so a method is employed to shorten the storage period by raising the storage temperature and using theoretical calculations (Arrhenius equation = when the temperature increases by 10°C, the reaction time doubles) to conduct accelerated testing.
