Preheat oven to 325 degrees F (165 degrees C). Grease a 9×5 inch loaf pan with non-stick spray. Sift together all-purpose flour, whole wheat flour, baking soda, baking powder, cinnamon, nutmeg, cloves, and salt in a large bowl until well blended.
Beat egg whites with a mixer until light and frothy. Stir in applesauce, brown sugar, zucchini, carrots, and vanilla until well combined. Mix in the raisins and pecans. Add the flour mixture, stirring just until blended. Pour the batter into the prepared pan.
Bake until a toothpick inserted in the center comes out clean, about 1 hour 20 minutes. Cool bread in pans for 10 minutes, then remove, and cool completely on a wire rack.
