Carrageenan-based hard capsule properties at different drying time

Shelf life of biocomposite can be monitored by many preservation methods such as drying of biocomposite. Upon drying, water molecule will be removed due to evaporation to surrounding and effect the biocomposite quality, chemical and mechanical properties. Over drying process will lead to the reducti...
