Vitamin C concentration in orange juice.

Post by beckles » Mon Feb 06, 2006 12:13 am

Hello there!

Alright, so I'm doing a write-up for an experiment, and I need to know the "accepted literature value" regarding whether or not the vitamin C content of orange juice changes when the pH is altered (either more acidic, or more alkaline) I've been trying to do research, but so far.. no luck.. :S .. Any help would be GREATLY appreciated!

Thanks in advance!

:D -Becky

If u r asking about cytosol pH-
Its a weak acid so if you add more acid to the cytosol, then due to common ion effect the dissociated concentration of vit. C will decrease. I guess the remaining vit. C may get crystallized...or remain there undissociated...


If u r asking about soil pH- I don't know. :roll:
