How to extend the shelf life of fruit juice?

Short-term extension requires low-temperature storage in well-sealed containers. If it needs long-term storage, preservatives must be added.

note:

Try not to add preservatives if you eat them yourself, because preservatives, as a chemical preparation, are bad for your health if you eat too much.

If long-term sales are needed, preservatives need to be added. Before adding preservatives, they must be sterilized before they can be stored for a long time.
