Whoosh! You know how intense vacuum-sealed coffee smells when you first open the can? What
makes it so aromatic is the fresh, concentrated and captured Volatile Oils in
the beans. Some has been lost already in the fast mass-grinding they've
done at the roastery. That's why coffee aficionados grind it in the store or at home so all the freshness possible is retained.

Freshness First: Volatile Oils in Your Food
The heady odors emitted from fresh fruit or ground coffee are more than appetizing, they represent the plant source's volatile oil content. Volatile oils are the delicate compounds within a plant—fruit, bean or vegetable—that give it its distinctive smell and taste. They are volatile in that they are easily destroyed by exposure to the air or to heat - fragile is an optional substitute adjective. They are desirable because they are crucial to the freshness—and healthiness—of food. (A substitute term for 'volatile' regarding oils in foods could be 'fragile').
Processing kills volatile oils, especially produce —through heat, through long exposure to air, and through the addition of chemicals and preservatives that artificially extend the life of the food (but not of the oils). Processed foods do not contain volatile oils. They will smell less appetizing than the fresh version, and not taste as good either. By contrast, the very presence of intense smell and taste in fresh foods signals the hidden virtues of the oils, which are often argued to have anti-bacterial properties and to contribute to cellular repair.
Clearly, we want to hang on to as many of these molecules as possible, all the way from harvest to plate. But how to go about this without eating a raw diet? Here are a few tips for preparation, cooking, and storage:
Use only fruits and vegetables while they're still fresh with no processing. Buy and use fresh raw certified organic produce and products whenever possible; they're well worth the expense and are environmentally responsible.
Always clean fruits and vegetable with a produce wash, then rinse well. After that, keep the slicing and dicing to a minimum. Food cut into small pieces means more surface is exposed to the air and more nutrients are lost. Bigger pieces cook slower, but more of the essence and flavors are retained.
The best and easiest cooking method is steaming, in a stainless steel basket over water with the pan covered. This method is quick, and fewer nutrients are emitted via steam or dispensed in cooking water.
If you can't steam, try to go with low and slow cooking. Lower heat and longer cooking time retains nutrients and flavor across the board. Learn how to use the lower power settings on your microwave; what's another two minutes, really? After steaming, the best cooking methods for vegetables in order of preference are: baking, then broiling, grilling, and low-power microwaving and using boil-in or bake-in-bags. (see Cook It Right).
You could probably guess that deep frying is a bad idea—but you might not expect that one of the worst ways to cook vegetables is to boil them in water. This completely leeches the oils out of the produce, leaving it totally depleted. You toss your volatile oils and massive amounts of nutrients down the sink, instead of down your throat.
Of course, sometimes you can't get around cooking produce in water. In that case, use a trick to get the volatile oils back into your diet. Freeze the boiling water. Put the water used to boil fruit (for a sauce or pie) in an ice cube tray. The flavorful and nutritious 'runoff' makes for smart ice cubes for drinks. Stored veggie cooking water (or veggie water ice cubes) make great soup stock for your next slow cooker extravaganza.
