Are vegetables frozen without blanching safe to eat?
Vegetables frozen without blanching are safe to eat, but the quality will not be good. Enzymes continue to be active and can cause the product to develop off flavors, toughening, discoloration, and loss of vitamin A and vitamin C. The shorter the freezer storage time, the better the quality of frozen raw vegetables will be. If possible, use them within a month or two. Note: It is not necessary to blanch green peppers or onions.
