The interaction of chitosan and olive oil: effects of degree of deacetylation and degree of polymerization

Autor: Ian Ken D. Dimzon, Jürgen Ebert, Thomas P. Knepper

Publikováno v: Carbohydrate polymers. 92(1)

The combined effects of degree of deacetylation (DD) and degree of polymerization (DP) on the ability of chitosan to interact with olive oil was studied. The oil-binding test, a method that makes use of olive oil as a representative fat, was adopted
