Did you know that nutritional content is often higher in frozen vegetables than in fresh? Vitamins begin to dissipate in certain vegetables, such as corn and peas, within minutes of picking. By a few hours, they may have lost up to half of their nutrient value. Freezing quickly after harvest is sometimes the best way to lock in flavor and food value. Also, since the frozen vegetable companies have huge buying power, they often get the best part of the crop.
