In Japan, food labels often display two types of dates: the expiration date and the best-before date. Both are important for indicating the quality and safety of food, but they have slightly different meanings. In this blog, we’ll explain the difference between expiration and best-before dates in a clear and simple way.
1. Expiration Date (消費期限; しょうひきげん)
The date when food is no longer safe to eat
The expiration date refers to the period when the food is considered safe to eat. This applies to perishable items like bento lunches, cakes, and sandwiches. Once the expiration date passes, the safety of the food is no longer guaranteed, so it’s recommended not to consume it.
- Examples: Fresh food, deli items, cream-based cakes
- Note: Avoid eating food past its expiration date as it may no longer be safe.
2. Best-before Date (賞味期限; しょうみきげん)
The date when food is still delicious
The best-before date indicates the period when the food can be enjoyed at its best flavor and quality. This applies to longer-lasting foods like snacks, instant noodles, and canned goods. After the best-before date, the food doesn’t immediately become inedible, but the taste or texture may change.
- Examples: Snack foods, canned goods, dried noodles
- Note: While food is still edible past the best-before date, it may not taste as good.
3. Why It’s Important to Follow Expiration and Best-before Dates
Understanding the difference between expiration and best-before dates helps you manage your food better, which can also contribute to reducing food waste. Avoiding unnecessary waste helps you use your ingredients efficiently, benefiting the environment as well.
4. Foods Without Required Date Labels
Not all foods require a date label. Some foods, due to their long shelf life and stability, are exempt from having expiration or best-before dates.
- Salt
- Sugar
- Chewing gum
- Ice cream
- Bottled water (under specific conditions)
These products can be stored for extended periods without significant quality changes, which is why they are often exempt from date labels.
5. International Differences and Labeling
In English, expiration dates are often labeled as “Expiration Date” or “Use By,” while best-before dates are labeled as “Best-before Date.” Knowing these terms can help when dealing with international food products.
- Expiration Date (Expiration Date): American English
- Expiration Date (Expiry Date): British English
- Best-before Date: The date when the food is at its best
- Best-before Date (Use By): Sometimes used to ensure safety as well
Conclusion
By understanding the difference between expiration and best-before dates, you can enjoy a safe and delicious diet. Following these dates also helps reduce food waste and contributes to a more environmentally friendly lifestyle.
