“…Fatty acid composition of sunflower seed oil has been reported by a number of scientists to vary with planting location and with climatic conditions during the growing season. Sunflower oil content of fatty acids presented in this study is similar to that of Samarth and Mahanwar [26], Makhoul et al [27] and Hosein et al [28] who reported that sun flower oil contained palmitic (5.81-8.0%) stearic (3.35-6.3%) oleic (23.81-42.6%) and linoleic (46-65.73%) acids.…”

Published by United Scientific Group AbstractFatty acids composition are an important attribute in oil. The present study aimed to evaluate three selected sources of oil namely, sesame (Sesamum indicum L.) peanut (Arachis hypogaea L.) and sunflower (Helianthus annuus L.). Oil were extracted from seeds produced in Syria and irradiated with 3, 6 and 9 kGy of gamma-irradiation to assess the variability in fatty acid composition and to determine the relationship between irradiation and certain fatty acids. Results demonstrated that sesame, sunflower and peanut oils are of unsaturated type and contain mainly the oleic C18:1 and linoleic C18:2 fatty acids. Irradiation of seeds with medium doses (3 to 9 kGy) did not significantly affect the fatty acids contents. However, the un-saturated, saturated fatty acids, and the ratio of saturated to un-saturated fatty acids (TU/TS) were altered upon irradiation. These changes were significant for sesame and sunflower oils, but not for peanut oil. KeywordsFatty acids, Gamma irradiation, Peanut oil, Sesame oil, Sunflower oil IntroductionOils from vegetables are complex mixtures that contain several compounds and are made up of free fatty acids (FFA), triacylglycerols, glycolipids, diacylglycerols, phospholipids, and other minor components [1]. Vegetable oil usage is largely centered on the type of fatty acids present in the oil and these fatty acids fall into various lipid categories [1,2].Fat is an important dietary component, which affects both growth and health. Even though polyunsaturated fatty acids (PUFAs) have been investigated to have health benefits [3]. Compositions of vegetable oils are valuable information in understanding their functional, quality and nutritional properties. Increasing the content of saturated fatty acids can enhance stability with the concomitant increase of the proportion of solid fat and the melting temperature [4]. Oilseeds vary widely in their fatty acids composition, but tend to be rich in monounsaturated fatty acids (MUFAs) (e.g. peanuts) or PUFA (e.g. sunflower seeds) [5]. Also, the composition of oleic, linoleic and linolenic acids in oil has an effect on the oxidative stability [6].Gamma-irradiation has wide range of applications in food technology [7][8][9]. Irradiation causes molecular changes, among which the formation of free radicals is one of the most important for a high fat content foods that in turn can change the fatty acid composition and consequently the fat functional benefits [9][10][11][12][13]. The increase in free fatty acid was observed in beans and edible oils irradiated in the range of 1.0-20 kGy [14]. Polyunsaturated fatty acids are susceptible

“…Based on the excellent natural characteristics, vegetable oil derivatives are being used in numerous applications including adhesives, paints and coatings, and nanocomposites [66]. Use of Modified vegetable oil is strongly recommended to use in the polymer area [67]. Vegetable oils as biodegradable additives can be tried to improve the lubricating properties.…”

Lubricants are playing an important role in world industrial and economic development, mainly by reducing friction and wear in mechanical contacts. The outlook for eco-friendly MWFs for the next decade is 15% of global volume share. Due to ever increasing demand for environmentally acceptable products suitable for use as MWFs, vegetable oil-based MWFs are drawing the attention of researchers across the globe. Owing to the desirable properties of vegetable oils as cutting fluids, vegetable oil-based cutting fluids play an important role in conserving the environment by means of sustainability. This paper focuses on various vegetable oil being developed to promote biodegradable MWFs across the world. The performance of vegetable oils with respect to cutting and thrust force, tool wear, temperature, surface roughness in turning, drilling, milling and grinding a wide variety of materials are studied and reported. The review also throws light on the tribological behavior of vegetable oils that influence the lubricity in Metal working process. The review reveals that vegetable oils offer an alternative, eco-friendly and sustainable MFWs for the future of manufacturing.

“…Menurut Samarth dan Mahanwar (2015), pengembangan minyak nabati berbasis trigliserida untuk polimer komposit seperti cat, pelapis, perekat, dan nanokomposit lainnya dikembangkan karena dapat diperbaharui, biodegradable, ekonomis dengan aspek lingkungan yang sangat baik. Botros et al (1987) menjelaskan penambahan minyak nabati dari jenis minyak biji jerami, minyak kedelai, minyak biji remis, minyak jarak pada komposit NR dan SBR dapat meningkatkan kuat tarik, dan modulus 100%, ketahanan panas, kekuatan tarik setelah pengusangan, dapat meningkatkan ketahanan ozon pada vulcanizate karet.…”
