In this study it was found that vitamin C in frozen homogenates of representative raw fruits and vegetables is stable for some period of time with the typical processing and storage methods used for the NFNAP.
Do Frozen Vegetables lose vitamin C?
Blanching caused a decrease in vitamin C and folic acid, whereas freezing affected vitamin C and carotene. Frozen produce may also lose nutrients the longer they are frozen. They should be used within 8 months to 1 year of purchase.
Does freezing food destroy vitamin C?
That being said, some research also suggests that frozen produce may retain its antioxidant activity despite the loss of water-soluble vitamins ( 6 , 7 ). Bottom Line: Blanching results in a loss of antioxidants, B-vitamins and vitamin C. However, nutrient levels remain fairly stable after freezing.
Are frozen fruits as healthy as fresh fruits?
Depending on the fruit, some may retain more nutrients frozen while others are better fresh. Nutrients in fruit are at their peak right after being picked. Because fruit is frozen quickly, it retains nutritional value. If your fresh fruit is truly fresh, the nutrient value may be similar.
Does freezing orange juice destroy vitamin C?

Johnston of Arizona State University East in Mesa.
