Selection And Storage Of Vegetables

General Guidelines for Selection

  • Consider the intended use. For example, canned tomatoes may be less expensive, can be kept on hand, take less time and produce a better chili than fresh tomatoes.
  • Time of year is important. Produce that is in season will usually give you the best quality and best buy.
  • Consider the storage available. Buy only what you can store and use within the recommended time.
  • Handle produce gently.
  • Poor quality vegetables usually have lower food value, less flavor and more waste.
  • Just before going to the grocery store check out counter, pick up frozen vegetables that are frozen solid and get them to the freezer as quickly as possible.
  • 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. Keeping vegetables in a plastic bag or in the hydrator (crisper) compartment of the refrigerator, or both, is suggested for increasing storage humidity.
  • DO NOT REFRIGERATE potatoes, sweet potatoes and hard-shell (winter) squash. Cold temperatures convert the starch into sugar which affects the flavor. Store them at cool room temperatures40 to 50 degrees 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.
  • Canned vegetables should be stored in a cool, dry place and used within a year for top quality.
  • Dried vegetables need to be in an airtight container and stored in a cool, dry place. They are best if used within a few months.

See the following information for storage tips specific to various fresh vegetables.

	     round spears and a fresh
	     appearance. A rich green color
	     should cover most of the spear.
	     Stalks should be tender almost as 
	     far down as the green extends.
	     Size of stalk has no relationship
	     to tenderness. 
		
		AVOID:                                   
		- Stalks that are soaking in
		  water.      
		- Tips that are open and spread
		  out, moldy or decayed.                
		- Ribbed spears (with
		  up-and-down ridges, or that
		  are not approximately round).    
		  All the above are signs of
		  aging, and mean toughness and
		  poor flavor.               
		- Avoid excessively sandy
		  spears because sand grains
		  can lodge beneath the scales 
		  or in the tips and are 
		  difficult to remove in
		  washing.

	     are bunched, you can judge their           
	     freshness fairly accurately by the         
	     condition of the tops. Badly
	     wilted or decayed tops indicate a
	     lack of freshness, but the roots
	     may be satisfactory if they
	     are firm.
