Development of filtration system for the collection of soaking water during bedak sejuk preparation

“Bedak Sejuk” or fermented rice powder is a traditional cosmetic product used by locals that is made from fermented rice. To start the process, the rice grains are soaked in water at 1:1 (w:v) ratio and continuously soaked until the rice gains fully dissolved into flour paste slurry. The soaking w...
