Maintain Quality & Safety
Storage does not improve the quality of any food. The quality of a food item will also not decrease significantly during storage as long as the food is stored properly and used within the recommended time frame.
Quality is not the same as safety. A poor-quality food may be safe, such as stale cereal, overripe fruit, or soured pasteurized milk. An unsafe food may have good quality in terms of appearance and taste but have a high (unsafe) bacterial count. For example, improperly canned food may contain Clostridium botulinum (which causes botulism), thus making it unsafe. Or cooked chicken may be placed on a plate that held the raw chicken and becomes contaminated. The goal of home food storage is to provide both safe and high-quality foods.
Maintaining a food’s quality depends on several factors: the quality of the raw product, the procedures used during processing, the way the food is stored, and the time length of storage. For example, fresh-picked corn will store better than corn that has been in the market for a few days; a tightly folded inside cereal box liner will prevent a ready-to-eat cereal from becoming limp. The recommended storage time takes these factors into consideration.
Since bacteria can frequently enter into food through careless food handling, keep everything – hands, pantry, shelves, and storage containers – clean.
To help assure quality, some products have “open dates” on the package. Product dating is optional on most products. Dates may also be “coded” by the manufacturer and only understood by them.
Sell-by Date: This is the last recommended day of sale. The date allows for home storage and use. You will find the date after the statement, “Sell by (a date).” Bread and baked goods may have “sell-by dates.”
Use-by Date: Tells how long the product will retain top quality after you buy it. You will find this date after the statement, “Use by.” Some packaged goods have “use-by dates.”
Expiration Date: This is the last day the product should be used or eaten. You may find this date after the statement, “Do not use after (date).” Yeast and baking powder have “expiration dates.”
Pack Date: Canned or packaged foods may have dates, which tell you when the product was processed. This does not tell you how long the food will be good.
These are guidelines; if a food is not properly handled, its storage life will be shortened. Follow these tips for purchasing top-quality foods that have been handled safely.
For best results in maintaining product quality, practice the rule: FIRST IN, FIRST OUT. This means you use the oldest products first and the newest products later. A good practice in the home is to place the newly purchased products behind the same products already on the shelf. It may help to write purchase dates on products without “open dates” on the package. Follow recommended storage times for the refrigerator (HGIC 3522), freezer, and pantry (See the chart on the following pages.)
- Storage areas near oven ranges, hot water pipes or heating ducts should not be used because heat and moisture can cause food to lose its quality more rapidly.
- Insect infestation can occur in any home. Susceptible foods include cereals, flour, seeds, baking mixes, spices, candy, dried fruits, and dry pet foods. Avoid purchasing damaged packages of foods and keep cupboard shelves and pantry areas clean. Storing food in tightly sealed glass, metal, or rigid plastic containers may help reduce the chances of insect infestation.
- High temperature or humidity may reduce storage time considerably.
- Pantry foods will possibly be safe beyond recommended storage time, yet eating quality (flavor and texture), and nutritive value will be reduced.
