Jojoba oil is a source of specialty chemicals and its uses for industrial application are gaining in adaptability and importance. For prolong use of jojoba oil, the details of its storage behaviour are required. This information is scarce for the products obtained from Indian locations. In this study, the ageing effect on the quality of oils was studied for oils from five locations of Rajasthan (India). The oils were extracted/expelled from the seeds that contained 2.5–3.9 wt.% moisture and 42–50 wt.% oil.Physico-chemical properties were determined by standard analytical test methods. Effect of storage time on quality of solvent extracted oil samples with respect to acid value, iodine value, saponification value and peroxide value were determined. The samples were stored for 18 months in the laboratory under climatic condition prevailing in Dehradun (India) during study period. The analysis of samples was done at an interval of 3 months. The properties of jojoba oils compare well with the International Jojoba Expert Council (IJEC) specifications. During storage, acid values, iodine values and peroxide values of the oil increase with time while saponification values remain almost unchanged.
