If i freeze my own fruit...?

will the nutritional value change? How long can i freeze them for without getting freezer burn and tasting gross?? And i was think i would just slice up some mangoes, bananas, and kiwis wash the mangoes and kiwis than throw them all in a plastic bag.. than the next day thaw them by just simply taking them out of the freezer for a couple hours till they are ready to be eaten... would this work?? Also, would it make a difference if i waited a month to thaw them and eat them rather than a day?? Will the longer i wait, will it loose its nutritional value more?
