Food date labels such as “use by,” “sell by,” and “best by” are causing people to throw away perfectly good groceries, adding to home waste. These labels are more about quality than hard and fast safety regulations, aside from baby formula. Making sense of them allows you to stretch the shelf life of pantry and fridge basics, save money, and minimize environmental footprint. This cookbook, edited by food safety experts and nutritionists, unlocks the secret of these labels and reveals 12 foods that are safe and tasty well beyond their dates so you can make the most of your kitchen efficiency.
Decoding Food Date Labels
- Food date labels are misleading, but they’re mostly concerning peak quality, not safety. “Use by,” “sell by,” and “best by” inform consumers and retailers about freshness, not impending spoilage. Understanding the differences keeps you from throwing away food too early, saving money and minimizing waste.
- For instance, “use by” suggests when a food is at its best texture or taste, but dietitian Toby Amidor asserts it is not a safety date eating after such a date is usually fine. “Sell by” indicates to stores how long to keep products, but shoppers can still use such products far past this point, though quality will deteriorate. “Best by” and “expiration” dates focus also on optimal experience, not on an absolute point of dissertation, unless mishandled.
- Proper storage is the secret to keeping it usable. Handled carelessly, even before its date, food is ruined by wrong refrigeration or exposure. Keeping sealed and refrigerated, you’re doing what the labels intend quality advice and comfortably trusting your senses to decide safety.
The Science of Food Spoilage
- Spoilage occurs when bacteria grow, and an awareness of their needs will keep you from this. Food safety specialist Janilyn Hutchings explains that bacteria require food, water, and warmth. Understanding these conditions enables you to store food in a way that slows microbial growth and delivers optimal shelf life.
- High protein or high carbohydrate foods like milk, eggs, or meat are most prone to spoilage, especially with the presence of moisture. Sterilizing and sealing food can be achieved in canning, killing bacteria, while refrigeration slows down their multiplication to a week. Freezing brings it to an end, although texture or taste will be changed later, so storage techniques become very crucial.
- Keeping foods in tight sealing containers and keeping them cool and dry minimizes bacterial risks. Keeping inventory turned over and checking for spoilage indicators like off smells or mold assures safety. Habits like these enable you to use foods safely past their dates, saving them from waste without losing quality.
Honey: Nature’s Preservative
Honey’s long shelf life depends on its low water content and high acid level, which render the microbe and bacteria environment uninhabitable. Its natural sugars dehydrate such microbe spoilers, and therefore honey becomes safe for years, or even centuries, if stored safely. This makes honey a reliable pantry item for sweetness or preservation.
- High Sugar Content: Honey’s high sugar concentration draws water out of microbes, inhibiting their growth.
- Acidic Nature: The acidity of honey repels bacteria, contributing to its antimicrobial properties.
