Whatever matter reaches the anus is at the end of the road as far as digestion is concerned and the anus is more concerned with excretion. The food is mechanically digested in the mouth by the teeth and tongue and chemically digested there by your saliva. It is then mechanically digested in the stomach where it's contents are mixed together with muscular contractions and chemically digested with hydrochloric acid and pepsin, etc. It is then moved to the small intestine where other things are added like pancreatic enzymes and bile, where some mechanical digestion takes place when peristalsis occurs that moves the matter through the alimentary canal, but mostly here it is chemically digested. The large intestine mainly removes excess water from the matter and helps to form solid matter for excretion. It is retained in the rectum until the sphincter muscles in the anus relax and allow for the passage of the stool. If anything though, it would be mechanical.
