What type of bowl is best for a fruit salad? I am planning on making a fruit salad for coworkers and want to make sure that none of the fruit start to go bad because of the contact with the bowl.

I am planning on using apples, oranges, grapes, pine apple, and possibly bananas.

What would be the best type of bowl to transport and serve this in: metal, glass, plastic, etc?
I don't think the bowl has anything to do with it, unless it is some sort of reactive metal, but you don't normally find food grade bowls made of a reactive metal?

To stop surface oxidation of non-acidic fruit (apples, bananas etc.) coat them with a suitable weak acid. See this previous answer  How to Prevent Apples from turning Brown
