Fruit juice is a juice product obtained by physical methods such as pressing, centrifugation, extraction, etc.It is rich in variety and many people like to drink it.

There are many types of juice. The first is the fresh juice in the fresh-keeping package.

Generally, it is packed in plastic bottles or house-shaped paper fresh-keeping boxes, indicating that the storage conditions are low temperature refrigeration, and the storage time is short, mostly only 7-10 days. This kind of juice is generally freshly squeezed, without high temperature sterilization, basically without sugar, sweeteners, preservatives, and the nutrients are well preserved. This juice must be kept cold and consumed within a short period of time. Next is fruit juice concentrate. Use glass bottles or plastic bottles, and store them at room temperature for a long time. This juice contains more sugar and additives, and the label will indicate the dilution ratio when drinking. Finally, pure juice. Generally, it is packed in carton or glass or plastic bottle, and can be stored at room temperature for more than half a year. Most of this kind of fruit juice is made of concentrated fruit juice produced in the origin of the fruit and water is added to restore the concentration of the original fruit juice, and is subjected to instant high temperature sterilization treatment. Nutrients, especially vitamins, were lost, and the flavor of the fruit changed slightly.

The fruit juice retains a considerable part of the nutrients in the fruit, such as vitamins, minerals, sugar and pectin in dietary fiber, and the taste is also better than ordinary boiled water. Compared with water and carbonated beverages, fruit juice does have considerable advantages. If a reasonable diet cannot be guaranteed, it is also a good way to supplement some nutrition by drinking juice in moderation. Some people don't like to drink boiled water. Juice with a sweet taste can increase their water intake and ensure the body's need for water, which is indeed a good thing.

But most fruit juices are "delicious" because they are seasoned with sugar, sweeteners, sours, spices and other ingredients. Many people think that fruit juice can replace fruit, and drinking fruit juice can supplement the nutrients in fruit (such as vitamin C), especially children who do not like fruit should drink more, or even completely replace drinking water. But fruit juice can't completely replace fruit either. Whole fruit is always the nutritionally best option for anyone who can eat fresh fruit.
