Does pasteurizing orange juice wreck the vitamin C?

Question

Fresh not frozen oj is pasteurized and I have heard that this makes is so that we cannot absorb the vitamin C. True?

Answer 1

Heat does destroy vitamin C, but we boil vegetables for a lot longer than OJ is pasturised for (depending on the method) so although it may destroy some, there is plenty left. Fruit juices usually state on them how much Vitamin C they contain, so some will be added to make up what loss there is.

This article (though it deals with milk) suggests that 20% of the vitamin C content may be lost in milk:

However, Vitamin C is an acid (ascorbic acid) and therefore may survive better heated in an acid environment such as fruit juice than a neutral or alkaline environment. Certainly adding bicarbonate of soda to green vegetables to maintain their greeness when cooked destroys ALL the vitamin C!

Answer 2

Raw juices are far better for you than pasteurized juices. Vitamin C is not the only thing that can get destroyed by heat, there are valuable enzymes that are really beneficial as well. You might find some interesting information on the link below.
