In biochemistry|lang=en terms the difference between hydrolysis and chitinolysis

is that hydrolysis is (biochemistry) the degradation of certain biopolymers (proteins, complex sugars) by the chemical process that results in smaller polymers or monomers (such as amino acids or monosaccharides) while chitinolysis is (biochemistry) the enzymatic hydrolysis of chitin into chitobiose.
