In a large bowl, combine the flour, sugar, pudding mix, baking soda, baking powder and salt. In another bowl, whisk the eggs, milk, oil, lemon juice and extract. Stir into dry ingredients just until moistened. Fold in the zucchini, poppy seeds and lemon peel.
Pour into two greased 9-in. x 5-in. x 3-in. loaf pans. Bake at 350° for 50-55 minutes or until a toothpick inserted near the center comes out clean. Cool for 10 minutes before removing from pans to wire racks to cool completely. Yield: 2 loaves.
