My first reaction would be that CS may keep bacteria from growing, but it would do nothing to preserve the essential, live qualities of fresh juice that make it useful. I just keep a small container of lemon wedges in the fridge and squeeze them into my glass or bottle of water, cutting new wedges every couple of days.
Be well,

Hi Group,

Just squeezed four cups of fresh lemon juice...is it okay to add CS to the juice as a preservative?
TIA,
