Quality assessment of cold-pressed strawberry, raspberry and blackberry seed oils intended for cosmetic purposes.

Abstract

Background. Cold-pressed berry seed oils are used for consumption and other applications including skin and hair care. They are natural products which gain the attention of customers. In this study, strawberry, raspberry and blackberry seed oils used for cosmetic purposes, purchased from three different European producers, were analyzed. The aim of the study was to assess the quality and oxidative stability of the berry fruit oils, thus they were analyzed after purchase and after 4 and 8 weeks of storage at room temperature.

Materials and methods. Acid and peroxide values were determined in the tested oils, as was oxidative stability, which was measured using pressure differential scanning calorimetry (PDSC). Additionally, fatty acid profiles and their distribution at sn-1,3 and sn-2 positions of triacylglycerols were characterized.

Results, principal. Most of the fatty acids of the tested berry seed oils are polyunsaturated fatty acids (67.04–74.95%). The results show the low quality of the tested oils in terms of oxidative stability (high peroxide values: 21.9–249.6 mEq O2/kg oil).

Conclusion. Based on this study, it is necessary to evaluate the effects of these products on the body. Moreover, standards clarifying the oxidation of cosmetic oils should be set internationally.

Keywords: raspberry oil, strawberry oil, blackberry oil, oxidative stability, fatty acids, PDSC
