Abstract

Ginger is one of the most widely produced horticultural commodities from the spice and medicinal plant group compared to other commodities. Ginger can be used in the form of dry powder or the form of ginger essential oil. Ginger essential oil has properties: it is unstable and susceptible to oxidation and degradation in the presence of oxygen, light, metals, and high temperatures. Encapsulation is a solution to maintain the quality of red ginger essential oil. This study provides information about the drying process of red ginger with a rotary dryer, extraction kinetics using the soxhletation method, and encapsulation of red ginger essential oil. 1.5 kg of red ginger cut into cubes with dimensions of ± 4 mm3. The pieces of red ginger were put into a rotary dryer which rotated at a speed of 19, 30, and 55 rpm. The dried ginger pieces were then mashed. The ginger powder was extracted in a socket at a temperature of 70 o C using n-Hexane as solvent. The resulting ginger essential oil was then encapsulated in Alginate-PVA beads. Drying with a rotary dryer was still less effective in drying red ginger with a maximum moisture content of 20%. The extraction process using the Soxhlet method with n-Hexan as a solvent resulted in a yield of 7.834% (extraction kinetic constant of 0.211). Ginger essential oil can be encapsulated in Alginate-PVA beads with an average diameter of 1.25 mm.
