How long can you store or refrigerate juice before it loses its 'potency'. Enzymes or whatever it has that makes it functional?

Fresh juice starts losing its potency from the minute you make it... We recomend to drink fresh juice as soon as posssible. If you need to store it, we reccomend storing it in a SEALED container, with little/no air space, (a mason jar or thermos) or better yet, use a foodsaver and vacuum seal the container (to remove air). If storing the juice, we recomend drinking it within 24 hours.
