Pengaruh Lama Penyimpanan terhadap Rendemen dan Kualitas Minyak Atsiri Kulit Jeruk Manis (Citrus Sinensis L.)

Abstract

Determination the influence of storage time on Sweet orange peel essential oil quality is conceived. The variation of storage time was 1, 2, 3, 4, 5 and 6 days. Essential oil obtained by distillation for 6 hours, oil and water separated by the addition of anhydrous Na2SO4 then weighed and calculated rendement. Oil from peel stored at 1, 2 and 3 days blended into one (short storage) as well as in the oil stored at 4, 5 and 6 days (long storage). Then determined the quality of essential oils which include density, refractive index, acid number and solubility in alcohol 96% and the main components of essential oils is determined by GCMS. The results showed a higher yield long storage than the short storage. The mean specific gravity, refractive index, acid number and solubility in 96% alcohol in a short storage of oil are respectively 0.8251, 1.3843, 0.2304 and 1:1 up to 1:10 clear, while the long storage of oil, respectively 0.8391, 1.4623, 1.0140; 1:1 up to 1:10 clear. The main components of sweet orange peel oil is D-limonene, which is short of storage tends to produce a percentage of D-limonene is greater.
