How long does orange juice retain vitamin C?
The Difference Between the Two
A 2009 study published in “Family and Consumer Sciences” found that after three days, orange juice stored in the refrigerator retained at least 94 percent of its vitamin C, and after seven days it retained at least 91 percent.
Does vitamin C disappear from orange juice?
Oxygen in the air is responsible for most vitamin C loss in packaged orange juice, meaning routine handling during the production process as well as storage in non-airtight containers after opening can reduce the amounts of vitamin C both before and after purchase.
Does the level of vitamin C in orange juice change over time?
[19] These authors report a 2.7% loss of vitamin C in orange juice at 4 ◦ C. Goyle and Ojha [26] have reported that orange juice can lose 5 to 8% of its vitamin C during storage.
Does old orange juice have less vitamin C?
The orange juice samples that were further away from expiration dates had a higher concentration of vitamin C. The titration methods I did indicated that expiration dates did play a role in vitamin C content in orange juice. The more expired orange juice samples had less vitamin C content.
Does vitamin C content decrease over time?
Vitamin C has been widely studied and, in one paper, was shown to degrade by approximately 50% in 4 weeks in the juice of different fruits. Figure 1 shows the concentration of vitamin C in the juice of an orange at 4 °C and at room temperature during the course of 4 weeks.
Does vitamin C degrade over time?
Vitamin C can be destroyed by heat and light. High-heat cooking temperatures or prolonged cook times can break down the vitamin. Because it is water-soluble, the vitamin can also seep into cooking liquid and be lost if the liquids are not eaten.
Is vitamin C destroyed by processing the juice?
The pressing process resulted in a loss of vitamin C of about 22%, while pasteurization at high temperature (85 °C) reduced the content of ascorbic acid by 35% compared to the filtered juice.
How can you prevent the loss of vitamin C in fruit juices?
To prevent the nutrition in fresh fruit juice from loss, you should drink it right after extracting. So don’t extract more than you need. If you can’t drink it up in one time, store it in a fridge, and prevent its contact with air. Among all nutrient loss, Vitamin C is the fastest during storage.

Does cold temperature destroy vitamin C?

Is it better to drink orange juice or take vitamin C?
Schweiggert’s team set out to answer that question. The researchers found that the production of pasteurized orange juice slightly lowered the levels of carotenoids and vitamin C. But at the same time, it significantly improved the carotenoid and vitamin C bioaccessibility — or how much the body can absorb and use.
Should I drink orange juice or take vitamin C?
The answer is simple: it’s not. Orange juice is simply healthier and has many nutrients, in addition to being a rich source of vitamin C itself. Therefore, there is a greater benefit to having a whole food (fruit in this case) than a vitamin in a pill form.
