The usual way to keep turnips is to give them a coat of paraffin and store in a cool area.

Yet another possible example of the common language dividing people. When I hear "paraffin" from anyone north of the equator I think of what in Oz is called kerosene (if it's liquid) or mineral wax (if it's not), neither of which I'd want on my carrots.

So, bobad, what is it you mean by paraffin? I presume it's a vegetable oil.
