What specific quality degradation is cited as an example for a 'Best By' date on crackers?

Answer

When the crunch factor begins to fade

The 'Best By' or 'Best If Used By' date is specifically designed to mark the point where the food item’s optimal sensory attributes begin to diminish. In the case of crackers, the text uses the deterioration of texture as the defining indicator. The date suggests the point at which the characteristic desirable crunchiness starts to noticeably decrease, even though the chemical safety of the product remains intact for consumption beyond that date.
