چکیده

در این پژوهش راندمان، ساختار اسید چرب و خصوصیات فیزیکوشیمیایی و کیفی روغن خام دانه مرو (Salvia macrosiphon, Boiss) مورد بررسی قرار گرفته است. اسیدهای چرب اصلی به ترتیب اسید آلفا لینولنیک ،اسید لینولئیک و اسید اولئیک بودند. نسبت اسیدهای چرب امگا 3 به امگا 6 ، 6/1 و نسبت کل اسیدهای چرب غیر اشباع به اشباع 23/7 بود که خصوصیات خوب تغذیه‌ای و همچنین حساسیت بالای روغن را نشان می‌دهد. خصوصیات فیزیکوشیمیایی از جمله عدد یدی، اسیدی، پراکسید، پارامترهای رنگی L، a و b و همچنین ضریب شکست مورد بررسی قرار گرفت که مقادیر آنها به ترتیب gI2/100g oil 7/168، 50/0، 9/1، 22/59، 09/5-، 94/22 و 4723/1به دست آمد. میزان کل ترکیبات فنولی، توکوفرولی و استرولی به ترتیب mg oil 22/165، mg/kg oil 59/629 و mg/kg oil 6/2540 بود. پایداری اکسایشی روغن دانه مرو نیز 94/3 ساعت بود.

چکیده [English]

In this study, the oil yield, fatty acid (FA) composition and the physicochemical and quality characteristics of Salvia macrosiphon crude seed oil were determined. The main fatty acids ranked in the following order of abundance: α- Linolenic Acid> Linoleic Acid> Oleic Acid. The n3 /n6 FA ratio and polyunsaturated FA/ Saturated FA ratio were 1.6 and 7.23, respectively. The FA composition revealed that the oil had great potential to use as nutritional dietary component and also was very susceptible to oxidation. The physicochemical properties such as Iodine ( 168.7 gI2/100g oil) , Acidic ( 0.5) and Peroxide ( 1.9) Value, color ( L: 59.22, a: -5.09, b: 22.94) and refractive index (1.4723) were also determined. Total phenol, tocopherol and sterol content were 165.22 mg GA/kg oil, 629.59 and 2540.6 ppm. In addition Oxidative Stability Index was 3.94 h.
