Chemical composition and oxidative stability of safflower oil prepared from safflower seed roasted with different temperatures. We manufacture and distribute fine chemicals and laboratory products - with quality and delivery you can count on every time. 80%). Introductory, Conceptual, and GOB Chemistry Book: The Basics of GOB Chemistry (Ball et al.) The content of α-tocopherol in safflower oil gradually increased from 441 to 520 mg/kg as roasting temperature increased from 140 to 180 °C. Safflower Oil, chemical structure, molecular formula, Reference Standards. Grape seed oil also contains 0.8 to 1.5% unsaponifiables rich in phenols (tocopherols) and steroids (campesterol, beta-sitosterol, stigmasterol). Copyright © 2003 Elsevier Science Ltd. All rights reserved. In 15 samples of commercial refined safflower oil average values were refractive index 1.4748, sp.gr. Sunflower oil is the non-volatile oil pressed from the seeds of sunflower (Helianthus annuus).Sunflower oil is commonly used in food as a frying oil, and in cosmetic formulations as an emollient.The world's total production of sunflower oil in 2014 was nearly 16 million tonnes, with Ukraine and Russia as the largest producers.. Sunflower oil is primarily composed of linoleic acid, a polyunsaturated fat, and oleic … The major fatty acid was linoleic acid (ca. View . Fat Composition Analysis Available data suggests that 100 g of safflower oil (high oleic acid) contains: 75.22% of monounsaturated fat, 12.82% of polyunsaturated fat, and 7.54% of saturated fat out of a total lipid of 100 g. It does not contain any cholesterol, but there is 0.1% of trans fats. The oxidative stability showed that, as the roasting temperature increased, the oxidative stability of safflower oil increased. Safflower oil from seeds roasted at 180 °C consisted of 4.99% palmitic, 1.69% stearic, 10.9% oleic, 82.0% linoleic, and 0.41% linolenic acids. However, the proportion of PI in the safflower oil increased significantly as roasting temperature increased (P<0.05), but, PE in safflower oil decreased significantly as roasting temperature increased (P<0.05). Tocopherol and tocotrienol homologues were identified, namely, α-, β-, and γ-tocopherols, and γ- and δ-tocotrienols, whereas no δ-tocopherol, or α-, and β-tocotrienols were detected.

Some polyunsaturated fatty acids account for 13 percent and saturated fatty acids make up approximately 8 percent. https://doi.org/10.1016/S0308-8146(03)00158-4. The expressed oil has a neutral taste profile. Search results for Safflower oil at Sigma-Aldrich. Packaging and storage— Preserve in tight,light-resistant containers. The major tocopherol in safflower oil was α-tocopherol. 1 - 2 of 2. The major phospholipid component of safflower seed oil is PI. Structures of Fats and Oils. Chart 1 Chemical structures of epoxidized safflower oil (ESFO), epoxidized linseed oil (ELO) and epoxidized perilla oil (EPLO), the two hardeners dithiodibenzoic acid (DTBA) and diphenic acid (DPA), and the imidazole (IM) initiator used in this study. Show Sort Related Categories: Safflower Oil Usp | Safflower | 8001-23-8 | S1004-500mlgl. The fatty acid compositions of safflower oils did not change with roasting temperature. Oleic acid (a monounsaturated fatty acid) is the main component of safflower oil, accounting for about 75 percent of it. Safflower oil has been used as cooking oil for a long time, though its benefits have begun to be touted only in recent years. However, tocopherol contents as high as 684 and 941 μg g − 1 of oil have been reported for traditional safflower and high-oleic acid safflower oil, respectively. It consists primarily of linoleic acid triglycerides. Structure Search. 0.9210, iodine number 143.4, crystallization temperature 7.4°C and squalene content 7.1 mg per 100 g. In total fatty acids were linoleic 77.5, oleic 12.9, palmitic 6.7, stearic 2.7 and myristic 0.1%; arachidic and eicosenoic acids were detected. Safflower oil (unroasted) consisted of 5.53% palmitic, 1.62% stearic, 11.00% oleic, 81.5% linoleic, and 0.40% linolenic acids. Four phospholipid classes, namely, PE, PI, PA and PC, were identified. Traditional and high-oleic acid safflower oils are composed of approximately 250 μg tocopherol per gram of oil or 50–100 μg tocopherol per gram of seed. Sunflower oil is primarily composed of linoleic acid, a polyunsaturated fat, and oleic acid, a monounsaturated fat.Through selective breeding and manufacturing processes, oils of differing proportions of the fatty acids are produced.
