Try breaking an apple open instead of cutting with a knife. Break the skin near the stem with thumb nails for an inch or so along a great circle line, then grasp between palms with the stem between the proximal joints of your thumbs, and press the thumb joints together while trying to pull the apple apart. Once the apple breaks, put one half aside for a few hours and see if the interior surface browns. YMMV with apple type & bruising. I suppose that breaking the fruit divides it between cell walls, while cutting breaks cell walls along the cut. Enjoy.
