The process involves a vacuum and sometimes freezing. The true form of the process does keep the vitamin in tact however as a means to speed up this process some of the vitamin is now lost so to a degree most concentrate is fortified.
Think of a centrifuge.

warmth destroys ascorbic acid. particularly, oranges and citrus fruit generally includes little to no diet C besides except they have basically been picked off a tree, so the glib answer is: because of the fact orange juice does no longer comprise diet C. (Edit): basically study with the aid of the different solutions. no longer very precise i'm afraid. No supplements are proteins, inspite of the certainty that one provitamin is an amino acid (tryptophan). diet C is a lot greater fragile than different supplements, and the fat-soluble ones A, D, E and ok isn't leached out via boiling because of the fact they do no longer seem to be soluble in water. it is likewise have been given no longer something to do with it being an acid, which that is not any longer besides. Ascorbic acid is an acid, although that is not any longer diet C strictly talking, because of the fact it won't be able to be absorbed with out flavonoids. Like maximum different supplements, diet C isn't a single compound.

Most vitamin C is added after all the processings. Two reasons for this, (a) it makes you think it's healthy (b) it serves as preservative.

I'm just guessing here, but I'd say they add it back in.
