How long will jelly stay good in sealed jar?

Answer 1

I would say about a week. I wouldn't cut it too close though... always want to be on the safe side. Usually after the Best Buy date you could keep it for about a week longer. BEST BUY only means that that is when it would be most enjoyable to the consumer not that it will go bad at that time.

Best By dates are a suggestion, if the food has been properly stored and not been exposed to extreme temperatures (which can effect the seal) while "on the shelf" it is fine to use as long as it doesn't smell off or have an odd taste. According to the USDA site, the quality of the flavor or color may no longer be 100% but there is nothing wrong with the product, as far as safely eating it is concerned. Keep it refrigerated and watch for changes in odor, color or taste.

"Sell-By" date tells the store how long to display the product for sale. You should buy the product before the date expires.

Best if Used By (or Before)" date is recommended for best flavor or quality. It is not a purchase or safety date.

"Use-By" date is the last date recommended for the use of the product while at peak quality. The date has been determined by the manufacturer of the product.

The 'best before' or "best by" dates are more about quality than safety, except for eggs.

Use by dates on baby formula and baby food should be followed due to the loss of essential nutrients. Eggs use by date should be followed due to bacteria.
