Abstract

A study was conducted to evaluate the storage stability of wild apricot kernel oils in different packages. Oil extracted through oil expeller were stored for 6 months at ambient conditions (13.17 to 18.47°C temperature and 60 to 70% RH) in 4 types of packaging material and evaluated for the changes in quality at periodic intervals of 3 months. The packaging materials were transparent plastic bottles (TPB), amber coloured plastic bottles (ACPB), transparent polyethylene pouches (TPP) and aluminium laminated pouches (AP). With the advancement of storage, the iodine value (IV) of wild apricot kernel oil exhibited steady decline from initial mean level of 99.90 to 92.12 g I2/100g whereas the acid value of oil exhibited steady increase from initial mean level of 3.74 to 9.78 mg KOH/g. Saponification value of wild apricot kernel oil exhibited only a marginal change i.e. 190.7 to 191.6 mg KOH/g after 6 months of storage. There were however, no significant change in the refractive Index of wild apricot oil. In brief, storage of wild apricot kernel oil packed in ACPB up to 6 months did not exhibit any adverse change in its physico-chemical quality and the values were well within the acceptable limits prescribed by PFA (Prevention of Food Adulteration Act).
