Does freezing 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.

Can I dissolve vitamin C in water and drink it?

Does cooking destroy antioxidants?

They measured the amount of antioxidants present before and after cooking. They found that baking, griddle-cooking and, yes, microwaving produced the lowest losses, while boiling and pressure-cooking were the hardest on antioxidants. Frying was somewhere in between.

Boiling may reduce antioxidant content by as much as 60 percent. Because antioxidants like vitamin C dissolve in water, it makes sense that these nutrients leach out into the water using this cooking method. If you're looking to retain antioxidants, save boiling for when you're making soup.
