There are many types and brands of barley leaves green juice. I don’t know the brand, but generally the shelf life of green juice is basically the same:

1. Green juice is similar to vegetable juice powder, and the general shelf life is About 12 months.

2. If it is in bulk, it will be easily oxidized after opening and the shelf life will be greatly shortened. Generally, it needs to be used up within 1-3 months.

3. Generally, green juice packaged in aluminum plastic is protected from light, dry, and not easy to volatilize. The shelf life of this type is relatively long, usually more than one year.
