After reading my post about the importance of enzymes and how heating/cooking kills them someone asked me about freezing. Here's what I found.

Question: Does freezing raw berries and fruits kill the enzymes in the same manner that heat does?
Answer: No, freezing raw berries, fruits and vegetables does not kill the enzymes contained in these foods like heat does. A vast majority of the enzymes stay intact. According to Ron Radstrom of Health Freedom Resources, only "some of them are destroyed (20 to 30%) but not the same amount as cooking. The quicker you freeze them the better and thawing them out gently is easier on the cell walls."
Fresh raw berries, fruits and vegetables are the best choice in obtaining essential nutrients and enzymes. The next best is frozen, especially if they are frozen immediately after they are picked.
Frozen fruits, berries and vegetables are often more nutritious than produce that has been shipped a long distance. In order to transport well, produce
needs to be picked before they fully ripen to minimize bruising. Plus, with the time involved transporting produce cross-country, what you think are fresh fruits, berries and vegetables may actually be 1-2 weeks old, if not more. This causes them to lose much of their nutrients. On the other hand, frozen produce is usually frozen right after it has been picked, thus preserving many of their nutrients and enzymes. To ensure that your berries, fruits and vegetables are of the highest quality, try to buy locally grown fresh produce whenever possible.
