Most of you probably know and have noticed that many grocery products are still good to be consumed, even if they have expired according to dates shown on labels. Often expiration date provided by manufacturer is more as guidelines, than actual date when certain product will go bad.
I recently read interesting post from businessinsider.com about research findings about expiration dates for some of the foods and drinks.
Here are some of the findings from research:
Tomato ketchup – Unopened tomato ketchup can be kept in room temperature for up to 12 months, but opened for 30 days. If kept in the fridge, tomato ketchup, in opened packaging will remain good to use for 6 months.
Chocolate (packaged) –Chocolate in packaging can be kept in fridge for up to one year. If kept in freezer chocolate will remain good for consuming for 18 months. Also chocolate will remain good for consuming anywhere in between 6 to 9 months when kept in rooms temperature. Factors such as: dark, dry place in not direct sun light, will be decisive for chocolate to stay good longer, when kept in rooms temperature.
Red and white wine – Usually not opened wine bottles can be kept in room temperature for about 3 years, although some wines are known to last for about hundreds years!
Opened bottle of Red or white wine can be kept in freezer anywhere from 4 to 6 months. However opened wine bottle kept in fridge will only remain good for consuming for about 3 to 5 days!
Pasteurized Milk – Pasteurized Milk is known for its abilities to keep its freshness even after expiration date, if kept closed and in right temperatures. Usually milk will still remain good to consume week after manufactures suggested expiry date, if kept closed and in the fridge. Frozen pasteurized milk will remain good for about three months, but only about 4 hours if kept in room’s temperature.
Yogurt – Can be kept frozen in closed packaging for 1 to 2 months, but not below -17 degrees Celsius. If kept in fridge in (closed packaging) yogurt will remain good for consuming for 7 to 10 days after expiration date suggested by manufacture. Yogurt will remain good to use 5 days after opening.
Eggs (Chicken) –Eggs kept in fridge will be good to use for period between 3 to 5 weeks, and about two weeks, if kept in room temperature. Also eggs can be kept frozen for up to one year.
Raw pork and beef meat – Pork and Beef can be kept in the fridge for 3 to 5 days, or 6 to 12 months, in freezer. However freezer temperature shouldn’t be bellow – 17 degrees Celsius.
Raw bird meat (chicken) – Can be kept in the fridge for 1 or 2 days, or frozen for up to 9 months. Bird meet is best, if kept in plastic container with tiny holes facing upwards.
Salad – Salad will remain fresh in fridge for 4 days, but sometimes even longer if kept in plastic container with tiny holes for air to flow in. It’s not suggested to freeze salad as they would lose some of the unique taste. Also salad shouldn’t be washed before storing in fridge.
Honey – Honey kept in dry, dark, cold place and in appropriate container/jar will never go bad.
