Preheat oven to 180 degrees C. Grease baking trays.
In a large bowl cream together the margarine, fructose and egg whites until smooth. Stir in the apple sauce, apple juice concentrate and vanilla. Combine the flour, bicarb soda, cinnamon and, if desired, salt; stir into the applesauce mixture. Finally, mix in the oats and chopped raisins. Drop by rounded spoonfuls onto the prepared baking trays.
Bake for 15 to 17 minutes in the preheated oven until biscuits are firm to the touch and lightly browned. Cool 1 minute on the baking trays before removing to wire racks to cool completely. When cool, store in an airtight container. I like to keep mine in the refrigerator.
