Flavors of vegetables: The green, leafy vegetables come in a variety of colors, starting from the bluish-green of kale to the vibrant kelly green of spinach. The leafy greens have random flavors, ranging from sweet to bitter, and again from earthy to peppery. Collards, bok choy, Swiss chard, and spinach have a mild flavor while mizuna, arugula and mustard greens have a peppery flavor. Bok choy is used mainly in stir-fries, as it remains crisp, even after cooking at a tender stage.
Check the color while buying: Always check the fresh lively green color of vegetables (or its respective color) while purchasing. The yellowish tinge indicates ageing of the vegetable and they will have an off flavor. The salad greens are a bunch of important nutrients and phytochemicals that does the maximum benefit to our day to day vegetable requirement. Frozen and canned vegetables can be healthy, but canned vegetables have the possibility of carrying excessive sodium. If you buy these, rinse them vigorously under cold water before use.
Look for spots, blemishes, fungal mold and marks of insecticide spray, do not buy such vegetables. Always purchase whole vegetables and not cut sections of the vegetable. Beware of food contamination and foodborne illness while buying vegetables.

Moreover, with increased storage time vitamin C content in vegetables degrades rapidly, thus hampering the nutrient value. If you cut and leave vegetables, oxidation occurs as they are exposed to the air. Thus, the enzymes are released and this results in discoloration of the vegetable. However, the vegetables are still perfectly edible and you can also stop this oxidation by adding ascorbic acid to the surface areas or by refrigerating the vegetables.
Storing Tips: Do not keep vegetables at hot and humid places. Always keep them refrigerated and pre-cut pieces should be particularly refrigerated or enclosed by ice. Keep the vegetables in plastic wrappings or in zip pouches to retain the nutrition for short periods until you use them.
Make sure to rinse all vegetables before eating. In fact, after you have purchased the vegetable, immediately wash them, especially the green leafy ones as they may have insects or harmful pesticides on them. This extends their shelf life. If you rinse them in salt water for few minutes, it ensures their ultimate cleanliness. They are free from sand, dust and any residual chemical sprays if used.
Keep your vegetables completely separated from raw foods like poultry, meat, and seafood. Vegetables should also not be kept in contact with cooking utensils or surfaces like cutting boards etc. You can wrap the green leafy vegetables in plastic or newspaper and then refrigerate, this increases their shelf life
