Abstract

Asam keping in the market are usually dried using conventional methods. A Portable solar drying system for rural community has been designed and tested for drying of garcinia atroviridis under Malaysia climate condition. The initial moisture content of garcinia atroviridis was 90% in wet basis. After drying, these products were used for seasoning in cooking. The final content moisture after using this solar drying system was 4.4%. The pore size for both samples was seen using an electron microscope with 500 times magnification. The biggest pore size for drying using the solar drying system is 28.4μm which is larger and more than conventional drying that around 13 µm. The pore size is an indicator of the dehydrated material and the heat supplied deeper.
