Does jicama turn brown after peeling?

I'm having a little dinner party tonight. I've already made some guacamole and want to serve sliced jicama as well as crackers for a tasty and healthy alternative. I'm the "organization queen" prior to these little get-togethers because once my guests arrive I start talking and cocktail-ing it and it all BETTER be organized :) If I peel and slice the jicama ahead of time, will it turn brown in the fridge? If not, should I just put it in a plastic bag with a damp paper towel which is what I usually do in a case like that. Thanks for any advice
