Preheat oven to 400 F. Line a muffin pan with papers or coat with a nonstick cooking spray.
In a small bowl, combine 1/2 cup flour and the apple in a small bowl, tossing to coat; set aside.
In a large bowl, combine the remaining 1 cup flour, whole wheat flour, brown sugar, baking powder, cinnamon, and salt; make a well in the center of the mixture.
In a small bowl, combine the milk, oil, and egg whites; stir well. Add the milk mixture, apple mixture, pecans, and raisins to the flour mixture, stirring just until the dry ingredients are moistened. Spoon the batter into the prepared pan, filling two-thirds full.
Bake for 20 minutes, or until golden brown. Cool in pan.
