Evaluation of Marketed Almond Oils [Prunus dulcis (Mill.) D.A. Webb] in Terms of European Pharmacopoeia Criteria.

Objectives: Almond oil marketed for health benefits and cosmetic purposes should be in compliance with the European Pharmacopoeia (EP) criteria. Therefore, in this study, 17 almond oil samples sold in pharmacies, herbal shops, online, and cosmetics stores were analyzed in terms of “almond oil” monograph criteria, which have been mentioned in EP 7.0. Materials and Methods: In this study, 17 almond oil samples sold in pharmacies, herbal, online, and cosmetics stores were analyzed in terms of “almond oil” monograph criteria, which have been mentioned in EP 7.0. Appearance, acidity value, and peroxide value of each sample were determined and the ingredients were identified by thin layer chromatography. Fatty acids were analyzed by gas chromatographic method using flame ionization detector. Results: It was determined that two of the 17 samples complied with EP 7.0 criteria. Conclusion: Almond oil, which is currently marketed according to the manufacturer’s own marketing and quality criteria, is excluded from the Turkish Food Codex Standards. Our research has shown that most of the products do not comply with the EP standards. For this reason, it should be ensured that almond oil is listed in this codex and urgent arrangements should be made for quality control analysis. [ABSTRACT FROM AUTHOR]
