Mucus does not digest any food component.why is it still important part of stomach secretion?

In the human digestive system, mucus is used as a lubricant for materials that must pass over membranes, e.g., food passing down the esophagus. ... A layer of mucus along the inner walls of the stomach is vital to protect the cell linings of that organ from the highly acidic environment within it.

Hope the above answer is helpful.

Mucus is important because it prevents the hydrochloric acid present in the stomach from reacting with the wall of the stomach, when there is no food present in the stomach.

Hi !
      Though mucus does not digest anything it is still important because it protects the stomach from HCL and helps pass bolus or food through the oesophagus

Mucus is important as it is the layer which protects the stomach from HCl.
