How long can freshly squeezed juice be preserved at room temperature?

Freshly squeezed juice should be drunk as soon as possible. Generally speaking, juice with high acidity has a long shelf life. Such as hawthorn juice, orange juice and grape juice. After opening, it can be stored in the refrigerator for 3-5 days, while peach juice and pear juice with low acidity should be drunk within 2 days after opening.

In order not to lose the nutrients in fruit and vegetable juice, it should be drunk as soon as possible. If you can't finish it, you can keep it in the refrigerator. It is worth noting that during storage, vitamin C is the fastest lost component in fruit juice. Different kinds of fruit juices are stored under different conditions, and the loss rate of vitamin C ranges from 20% to 100%.

Generally speaking, the greater the acidity of fruit juice, the longer the storage time of vitamin C, because vitamin C is the most stable under such conditions, and microorganisms are not easy to reproduce.
