Buy canned vegetables in cans without any signs of damage. Dried vegetables should be in tightly sealed in undamaged packages. See the following information for selection factors specific to various fresh vegetables. General Guidelines for Storage Proper storage is necessary to maintain food value, flavor, color and texture. Most fresh vegetables should be kept cold and humid.
Cold temperatures convert the starch into sugar which affects the flavor.
Fahrenheit is best. Potatoes should be kept in a dark, dry place. Sort vegetables before storing and remove any with bruises or soft spots. If you wash them before storing them, drain them well. Frozen vegetables should be stored at 0 degrees Fahrenheit or lower, and can be stored for 8 to 12 months.
