Preservative composition: Bottled purified water can be preserved for one year under normal conditions after filtration and disinfection. After adding this concentrated juice, preservatives must be added for long-term storage (the effect is mild, and it is forbidden to add preservatives directly). If you have to buy NFC (non-concentrated) juice, there are few or no antiseptic ingredients, but the price is expensive and the shelf life is usually less than one month.
If the addition amount is too small, the actual nutritional efficacy can only be said to be better than nothing.
The calories exceed the standard. In order to taste, it is actually necessary to add a lot of white sugar or fructose syrup with lower cost.
Secondly, the nutrition of fruit contains dietary fiber, vitamins, etc., some of which do not exist in fruit juice. Some vitamins are easily lost due to temperature change and oxidation during the concentration process, so extra vitamin C is bound to be added to this beverage.
But you don't need to worry too much. The antiseptic ingredients and nutritional ingredients are within the safety standards. Occasionally drinking this intake will have no obvious effect, but it is not recommended to drink it frequently.
