If the package says juice instead of juice drink, then the fruit content is 100%. You can drink it with water. That is, dilute it.
100% fruit juice is reduced from juice concentrate with purified water to the concentration of freshly squeezed juice, so it is called 100% fruit juice, and it is also called so abroad. But the ingredient list only write purified water + juice concentrate, in fact, the juice concentrate contains food additives, according to the guidelines to bring in, not more than ADI can be.
Juice concentrate is indeed a fruit juice component, there is no doubt about it, but after a low-temperature concentration, the first sterilization, packaging, and then in the opening, blending, the second sterilization, the loss of nutrients is certainly more, not as good as freshly squeezed, and even less good as eating fruit.
Huiyuan 100% fruit juice, orange juice, for example, from Brazil before shipping back to China, the orange to be dehydrated. Pulled to the factory, and then in accordance with the proportion of water and pulp in the fruit, adding a certain amount of pure water, reduced to normal juice, and did not add other preservatives. As for why the shelf life is long, because of the use of aseptic packaging, normal can be stored for about a year.
The current popularity of NFC juice, that is, non-concentrated reduced fruit juice, this is not dehydrated, like drinking our own juice, but there are room temperature and cold storage. As for why it is so expensive, a big reason is because it has a short shelf life, selling point to "fresh" as the main.
