Nope, don't worry about it. It's been pasteurized. Boiling fruit strips away delicate flavor and aromas. I use fruit purees when I make fruit beers for my wife, and i just add it to secondary, then beer on top. If you bottle, be sure to verify that your fermentation has stopped after adding the juice (because you will get a 2nd fermentation) - check with a hydrometer until you get consistent readings for 2 to 3 days, then bottle.
