Safety evaluation of wild apricot oil

Wild apricot, a variety of Prunus armeniaca, grows in the hilly regions of India. The seeds yield 27% of kernels. The potential availability of the kernels is 40,000 tons/year and these yield 47% of oil. The oil has 94% unsaturated fatty acids, rich in oleic and linoleic acids. Systemic effects and nutritional quality of wild apricot oil (WAO) were assessed in a 13-wk feeding study in weanling albino rats using a diet containing 10% WAO as the sole source of dietary fat. A similar diet containing groundnut oil (GNO) was used as the control. WAO did not manifest any toxic potential. The food consumption, growth rate and food efficiency ratio of rats fed WAO were similar to those fed GNO. The digestibility of this oil was found to be comparable to that of GNO. There were no macroscopic or microscopic lesions in any of the organs that could be ascribed to WAO incorporation in the diet. The results of this study indicate that WAO could be used for edible purposes without any overt toxic signs or symptoms. However a long-term study may be needed to confirm its innocuousness further.
