Hygroscopic characteristic of encapsulated products is important to determine the stability during its storage time. The hygrocopicity of the products was evaluated by storage the samples in a desiccator which has adjusted the humidity (RH ±75%) and the change of sample weight were monitored for one month. The hygroscopicity of encapsulated products of MFR extract was presented in Figure 4. encapsulated product by SD method was modified due to heat treatment during spray drying process.
