keeping fruit fresh

I don't think they will brown too much. If you are still worried you could soak them in lemon juice, but the fruit would become way too sour and I really don't recommend it.

I've heard of using the product called "Fruit Fresh" http://www.homecanning.com/usa/ALPro...CAT=511&P=2560, but also acidulated water- try 3 tablespoons lemon juice to one quart of water. You can also use orange and/or lime juice.

Pineapple should have high enough acidity that if it's still pretty juicy when you mix it all together, nothing should brown.

For fruit salad, what I do is first filet a few oranges and/or grapefruit in the bowl, then add in pineapple, then the rest of whatever fruit I have, tossing the bowl like a saute pan to coat the fruit with natural juices. The juice from the orange filets and pineapple will stop any browning for at least 18 hrs. Best thing about this is that you've added nothing other than the fruit itself.

There are fruit additives to stop browning out there, same as potato whiteners, and are nothing more than citric acid or vitamin C. Harmless, I guess, but still an additive and a bitter tasting one at that.

I usually do anywhere from 3 to 20 fruit platters a day and do them in the morning, but never more than 8 hrs in advance. I don't really have a problem with browning, but after 8 hrs under refrigeration I have to deal with juice pooling up in the platters, condensation forming under the cling wrap and misting on the platter, (water stains on the platter) and with some fruit, especially papaya, the fruit slices tend to "weld" to each other, making it hard for customers to remove fruit from the tray. Do them as close to consumption as possible is your best bet.

I had a friend who made peanut butter and banana sandwiches for her son to take to school. She peeled, cut and then dipped her bananas in 7-UP and she said they lasted and never turned brown. I was curious, so I tried it, and it worked!!! Fruit didn't turn brown, didn't taste too sweet or sour...actually it really didn't alter the taste at all. Hope it works for you.
