Did you know kiwifruit could also be used as a natural meat tenderizer?
That's because kiwifruit contains an enzyme called Actinidin. Just cut in half and rub kiwifruit over the meat, or peel and mash with a fork then spread it on the surface of the meat and let stand for 10 to 15 minutes or longer. The enzyme Actinidin also breaks down protein in dairy products. That's why when kiwifruit is combined with low fat ice cream, yogurt, or sour cream, it's best to serve and eat it right away. link
