1. Fruit juice contains much less nutrition than fruit. When the fruit is squeezed into juice, the pulp and membrane are removed. In this process, vitamin C is also greatly reduced, and vitamin C is something you must take in large quantities.
2. The size of the container will affect the vitamin content in the juice. Vitamin C will decompose when exposed to oxygen, and fruit juice in small containers will be exposed to more air during and after packaging.
3. When eating fruits, choose fruits with bright skin color, fresh meat, fragrance and freshness. If the moldy, rotten or moth-eaten area reaches or exceeds one-third of the fruit, it should be discarded decisively.
Fruits with more nutrition are usually made into more nutritious juice. Such as citrus fruits. However, sometimes, some nutrients, such as vitamin C, are artificially added to fruit juice. Please read the label carefully and find out the substance in it. Maybe some brands of apple juice or grape juice contain the vitamin C you need, but maybe other brands don't.
Once opened, the juice begins to lose its nutrition, so don't store it in the refrigerator for too long. The nutrition of aseptic juice made of citrus, grapefruit and pineapple can be preserved for 7- 10 days. Other low-acid juices, such as apples and grapes, can be kept for a week after opening. If you buy fruit juice that has not been sterilized at high temperature, you must eat it within one week even if it is unopened.
If you squeeze juice at home, wash the fruit with cold running water first to remove the bacteria on the surface. Wash it with fruit emulsion and hot water before each squeeze.
Don't rely too much on juice. If you read and choose widely, then juice may be helpful to your diet. However, eating some fruit is actually very simple, and it is really much better than eating juice.
