As shown in Fig. 1,great changes have taken place on coated apple slices after a period of time, and all of the slices became brown more or less. All the coatings were found adhering tightly to the surface of the apple slices during the entire storage time. The anti-browning effect of CS-AA coating on fresh-cut apples was not very apparent and the browning degree of slices coated with CS-AA coating was similar to the degree of the control apple slices. CS-CaCl2 coating helped maintaining the whiteness of apple slices as time went on and thus could be acted as a good anti-browning agent. Meanwhile, the color of apple slices coated with CS-CaCl2 coating was greatly lighter than the others at the end of storage time. This phenomenon indicated that the anti-browning ability of CS-AA coating was weaker than CS-CaCl2 coating.
