Soğuk Press Kiraz (Prunus avium) Çekirdeği Yayının Fizikokimyasal Özellikleri, Yağ Asidi, Sterol, Tokoferol ve Fenolik Bileşen Karakterizasyonu

Abstract

This study aimed to determine physicochemical properties (PV, FFA, total phenolic content, antioxidant activity), fatty acid, sterol, tocopherol and phenolic compound profile of sweet cherry seed oil. Sweet cherry oil was obtained by cold press process. Tocopherol and phenolic compounds were determined by HPLC and fatty acid and sterol composition were analyzed by GC system. PV and FFA values were found as 1.40 meqO2/kg and 2.71 % respectively. Apparent viscosity value was 0.057 Pa.s. TPC and AC values of the sweet cherry oil were determined as 22.17 mg/kg and 1.05 TE μM g-1. UFA content was higher than that of the SFA. SFA and UFA levels were 10.47% and 89.53 % respectively. MUFA (40.50 %) level was lower than PUFA level (52.03%). Oleic acid and linoleic acid were found to be major fatty acids with a ratio of 36.73% and 39.45 %, respectively. 14 different sterols were analyzed for sweet cherry seed oil. -sitosterol was found to be the major sterol with a ratio of 88.93 % followed by campesterol (3.12%), 7-stigmasterol (2.48%), 5-avenasterol (2.12%) and sitostanol (1.42%). Other sterols showed small amount (
