The expiration date does not equate to the final safe consumption date. After expiration, some foods remain safe to eat from a safety perspective, though their quality may have deteriorated to some extent. For example, frozen foods past their expiration date may not exceed pathogenic bacteria limits, and cooking them before consumption may not cause adverse reactions. However, due to prolonged storage, their flavor and texture may have changed, tasting less fresh, with reduced vitamin content and possible mild fat oxidation.How to store and consume food? Next, we'll share some practical tips: how to repurpose expired food items.
Staple foods: Bread typically has a shelf life of 3-7 days. After expiration, if it's merely dried out, it can be used as breadcrumbs. However, if moldy or sour, it should not be consumed.Biscuits have low moisture content. If sealed, they usually last over a year. As long as the packaging remains airtight and dry, they're generally safe to eat even after expiration if the taste hasn't changed.
Milk and dairy products: Discard expired milk if it appears thick and uneven, or if it has clumps or flakes.In summer, even if it looks normal, boil it first. If lumps form after boiling, it indicates excessive bacteria and should not be consumed. Powdered milk has no moisture and a long shelf life. If it hasn't expired for long, it can still be consumed as long as it hasn't darkened in color, has no visible impurities or foreign matter, and doesn't have a stale, moldy, or rancid smell.If only slight clumping occurs, it can be repurposed for baking or cooking through reheating.Therefore, discard these foods if they emit rancid odors or taste bitter/sour. If they lose their crispness, it indicates moisture absorption, leading to rapid spoilage, mold growth, or oxidative rancidity—making them unfit for consumption.After expiration, rancid odors or sticky casings indicate microbial growth, making them unsafe to consume.
