RESUMO
Encapsulated specialty oils commercialized in São Paulo state, Brazil, were evaluated for their identity (fatty acids profile) and compliancewith nutrition labeling (fatty acids and Vitamin E (alpha tocopherol) contents). Twenty one samples [flaxseed oil (6), evening primrose (5),safflower (8), borage (1), and black currant (1)] purchased from local markets or collected by the health surveillance agency were analyzed.The fatty acids and vitamin E contents were analyzed by gas chromatography with flame ionization detector and liquid chromatography withUV detector, respectively. Nine samples were adulterated (5 samples of safflower oil, 3 of flaxseed oil, and one of evening primrose). Amongthem, 3 flaxseed and 2 safflower oil samples were probably adulterated by the addition of soybean oil. Conjugated linoleic acid (CLA) wasfound in two safflower oils samples although the sale of oils with conjugated linoleic acid (CLA) is not permitted by the National HealthSurveillance Agency in Brazil (ANVISA). Only two samples presented all values in compliance with nutrition labeling (one safflower oilsample and one borage oil sample). The results show that a continuous monitoring of encapsulated specialty oils commercialized in Brazil isnecessary including a greater number of samples and sanitary surveillance.
