Fatty Acid Research and Health

The total carotenoid and flavonoid contents of flaxseeds were detected between 0.14 (Atalanta) and 0.66 μg/g (Sarı-85) to 255.71 (Sarı-85) and 424.29 mg/100 g (Cihanbeyli), respectively. Also, while total phenolic contents of flaxseeds are determined between 178.81 mg/100 g (Sarı-85) and 243.73 mg/100 g (Cihanbeyli), antioxidant activities of flaxseed samples were determined between 9.42 (Sarı-85) and 13.14 mmol/kg (Cihanbeyli). Quercetin and catechin contents of flaxseeds were identified between 26.19 (Sarı-85) and 45.69 mg/100 g (Atalanta) to 10.82 (Atalanta) and 25.44 mg/100 g (Kulu), respectively. While rutin amounts of flaxseeds vary between 10.20 (Sarı-85) and 15.78 mg/100 g (Kulu), resveratrol contents of flaxseed samples were detected between 5.72 (Atalanta) and 14.42 mg/100 g (Halfeti). Linolenic, oleic, linoleic, palmitic, and stearic acids were the most abundant fatty acids of flaxseed oils. Linolenic and oleic acid amounts of flaxseed oils are determined between 51.19 (Kulu) and 56.51% (Sarı-85) to 20.27% (Sarı-85) and 22.12% (Atalanta), respectively. The high amount of polyunsaturated fatty acids in flaxseed oils limits the use of this oil as cooking oil. Practical applications Flaxseed oil has several industrial uses. It is a plant that is cultivated in a geography extending from the west of the Mediterranean to India and is used for various purposes. Flaxseed is used in the production of edible and non-edible industrial oil. Its iodine number is around 180, and it is used in many fields, especially in the paint industry, and flaxseed, like other oilseeds, has a high oil content and a superior fatty acid profile.
