No (huge sigh of relief!). I find that when the apples have been slow cooked, the skins become so soft that they are unnoticeable. The peel also provides additional nutrients as it is high in fibre, in particular pectin. Pectin is a type of soluble fibre which is really beneficial to your digestive system and can help to control blood sugar levels. (See here for more information about pectin). So this unsweetened slow cooker applesauce is really good for your health:)
