Abstract


Effect of cutting method and drying systems on quality of dry ginger

Ginger (Zingiber officinale Rosc.) in generally used as spice to give flavor in food, beverage and traditional medicine industries. The main components of ginger rhizome are essential oil and resin. The objective of this experiment was to evaluate the effects of cutting method and drying system on yield and quality of dry ginger produced. The cutting method of rhizome was done vertically (slices) and horizontally (splits). Drying were conducted in drying oven provided with fan, solar dryer and direct sun drying. Dry ginger which was produced by split cutting method and solar drying system has the highest oil content (2.6%). The lowest oil content was 2.2%, produced by slices cutting method and direct sun drying system. Oven drying system gave the fastest drying time. Direct sun drying produced dry ginger with relatively high ash and foreign matter content. The yield of dry ginger were between 12.7 – 15.7%.
