Concentration and Stability of Ascorbic Acid in Marketed Reconstituted Orange JuiceThe examination of 17 brands of reconstituted orange juice showed that the ascorbic acid content decreases at a rate of about 2% per day. An ascorbic acid concentration of 28 mg/100 mL at the labeled expiration date is a reasonable expectation. If the original juice concentrate provides at least 46 mg/100 mL of ascorbic acid in the dilution at the time of preparation, the expected shelf-life to an expiration date value of 28 mg/100 mL is about 20 days.
