Based on the data on Figure 4, the product which encapsulated by SD method was more hygroscopic than the product by FD
method. The moisture absorption of encapsulated FD and SD products was occured only at the first week treatment and after that
the products was tend to stable. The hygroscopicity of powder would be influenced by drying techniques of the products and
matrix which used for encapsulation. Canuto et al.14 investigated the hygroscopic behavior of freeze-dried papaya pulp with
maltodextrin through adsorption isotherms. The addition of maltodextrin to papaya pulp formulations influenced the physicalchemical
composition of its powders and increases the water content at the monolayer, but decreases the hygroscopic
characteristics of powders. Hygroscopic characteristics of encapsulated FD product might be influenced by freeze drying
technique that involved more humid system.
