The benefit of using wheat grass powder as opposed to fresh wheat grass juice is its shelf life. Fresh wheat grass juice needs to be consumed quickly before it becomes undrinkable, but powdered wheat grass juice, such as Dyna-Green, can be kept on the shelf for quite some time. It is also much easier to prepare, keeping you from having to grow, cut and juice the wheat grass yourself.
Freeze Drying vs. Traditional Drying
Freeze-dried wheat grass juice lasts even longer than standard powdered varieties, and retains more of its nutritional value. Freeze drying is known to protect proteins and other chemicals during processing since it doesn't take place in a moist atmosphere. Freeze drying is done in a vacuum at -30 Fahrenheit, and evaporation of necessary nutrients is reduced exponentially.
A container of freeze-dried wheat grass juice can produce upwards of 30 servings, whereas an entire tray of fresh wheat grass can produce only about eight. This is a big difference, particularly when you consider the amount of wheat grass you would want to consume as part of a regular antioxidant regimen. You would need several trays growing simultaneously, and that is a time consuming prospect.
Freeze-dried wheat grass juice, like Dyna-Green, also carries the added benefit of a reduction in the strength of the taste. Those who have drank fresh wheat grass juice know how strong the odor and taste can be, to the point of turning some people away. Freeze-dried wheat grass juice, on the other hand, greatly reduces the negative aspects of the flavor, and can actually be quite delicious, especially when added to a smoothie or favorite juice.
