Vitamin C. Repeatedly tasks discover that orange juices made from frozen concentrated orange ( FCOJ ) have the very best vitamin C ranges compared to freshly squeezed or not-from-concentrate ( NFC ) juices. That is due to the truth that vitamin C degrades over time in recent and NFC, however doesn’t degrade as a lot in FCOJ on account of it being frozen till reconstitution. When you’re evaluating a NFC product which has been saved for roughly three weeks vs a newly reconstituted FCOJ, the FCOJ would certainly have a better vitamin C focus.

Additionally another factor to think about is that if the FCOJ is reconstituted to the identical power as recent or NFC.
