Food Expiration Dates

Food Shelf Life Recommendations

Version 2.0

1/14/2004

Grocery product shelf life is based upon the Manufacturer’s Date Packaged (DP) code. Manufacturers encode the Date Packaged somewhere on the product in a form unique to their internal procedures. My objective is to provide Date Packaged (DP) code keys for well-known products to assist your food purchasing and rotation efforts. Remember that these timeframes are the manufacturer’s recommendations for MAXIMUM freshness and nutrient value. Several vendors indicated their products are edible long beyond the published recommendation dates.

In order to maintain freshness within the suggested expiration dates, food should be stored in a dry, cool location. Discard any food product exhibiting changed color, odor, or taste. Storage temperature has a great influence on shelf life. Per Del Monte – a 15-degree change reduces expected shelf life by 50% (ideal temp is 65; if stored at 80, then shelf life is reduced by 50%). Do not freeze canned goods; the added moisture may cause the seams to swell and burst during thawing.

Recommended product Shelf life is defined as MOS (months) Unopened and Opened. Both of these timeframes are calculated using the Date Packaged (DP) as the base. Unopened refers to total months the product can be stored at home. Opened refers to the total months (or days or weeks) the product can be stored once it has been opened. If the chart has a time recommendation for Opened, consider it as a SUBSET of the Unopened timeframe. For example, if a product has an Unopened shelf life of 12 months and an Opened recommendation of 3 months, the following statements are true:

This chart is a work in progress. Feedback for additions, corrections or improvements should be forwarded to czimmer@gte.net for inclusion in a subsequent update. The chart is organized closely to the sequence of the generic Cupboard Storage Chart at County Extension sites (e.g. http://www.oznet.ksu.edu/dp_fnut/HRAP/STORAGE/cupstor.htm ). I’ve included the Extension product recommendations in the table. They are listed without a specific manufacturer entry and with "generic" in the comment column.

Food categories include:

CHART COLUMN DEFINITIONS:
