Extraction of apricot kernel skin oil and analysis of its nutritional composition

Ma, Y. and Ding, P. F. and Wang, L. X. and Wei, D. and Wang, S. and Li, Y. F. (2025) Extraction of apricot kernel skin oil and analysis of its nutritional composition. International Food Research Journal (Malaysia), 32. pp. 208-215. ISSN 2231 7546

Apricot kernel skin (AKS) is not fully utilised, except for some that are used as feed. In the present work, the effect of extrusion pre-treatment on the extraction yield, acid value, and peroxide value of AKS oil (AKSO) was investigated. In addition, the physicochemical properties, fatty acid and triglyceride compositions, Sn-2 fatty acid distribution, and content of various active ingredients in AKSO were further analysed. The results showed that AKS contained 12.1% crude oil. Furthermore, AKSO contained approximately 90.0% unsaturated fatty acids, and was high in tocopherols, phytosterols, squalene, and polyphenols. After AKS was extruded, granulated, and extracted with hexane as a solvent, the quality and extraction yield of AKSO were significantly improved, confirming its feasibility for AKSO extraction. From the perspective of nutrition and cost-efficiency, AKS could be a promising new oil-bearing resource, and AKSO could be used as a nutritional oil in food, medicine, and cosmetics.

Abstract

Apricot kernel skin (AKS) is not fully utilised, except for some that are used as feed. In the present work, the effect of extrusion pre-treatment on the extraction yield, acid value, and peroxide value of AKS oil (AKSO) was investigated. In addition, the physicochemical properties, fatty acid and triglyceride compositions, Sn-2 fatty acid distribution, and content of various active ingredients in AKSO were further analysed. The results showed that AKS contained 12.1% crude oil. Furthermore, AKSO contained approximately 90.0% unsaturated fatty acids, and was high in tocopherols, phytosterols, squalene, and polyphenols. After AKS was extruded, granulated, and extracted with hexane as a solvent, the quality and extraction yield of AKSO were significantly improved, confirming its feasibility for AKSO extraction. From the perspective of nutrition and cost-efficiency, AKS could be a promising new oil-bearing resource, and AKSO could be used as a nutritional oil in food, medicine, and cosmetics.
