ABSTRACT BACKGROUND High-oleic (HO) seed oils are being introduced as replacements for trans fatty acid (TFA)–containing fats and oils. Negative health effects associated with TFAs led to their removal from the US Generally Recognized As Safe list. HO oils formulated for use in food production may result in changes in fatty acid intake at population levels. Objectives The purposes of this study were to 1) identify major food sources of soybean oil (SO) and canola oil (CO), 2) estimate effects of replacing SO and CO with HO varieties on fatty acid intake overall and by age and sex strata, and 3) compare predicted intakes with the Dietary Reference Intakes and Adequate Intakes (AIs) for the essential fatty acids (EFAs) α-linolenic acid (ALA) and linoleic acid (LA). Design Food and nutrient intakes from NHANES waves 2007–2008, 2009–2010, 2011–2012, and 2013–2014 in 21,029 individuals aged ≥20 y were used to model dietary changes. We estimated the intake of fatty acid with the replacement of HO-SO and HO-CO for commodity SO and CO at 10%, 25%, and 50% and evaluated the potential for meeting the AI at these levels. RESULTS Each modeling scenario decreased saturated fatty acids (SFAs), although intakes remained greater than recommended for all age and sex groups. Models of all levels increased the intake of total monounsaturated fatty acids (MUFAs), especially oleic acid, and decreased the intake of total polyunsaturated fatty acids (PUFAs), particularly LA and ALA. Replacement of traditional with HO oils at 25–50% places specific adult age and sex groups at risk of not meeting the AI for LA and ALA. Conclusions The replacement of traditional oils with HO varieties will increase MUFA intake and reduce both SFA and PUFA intakes, including EFAs, and may place specific age and sex groups at risk of inadequate LA and ALA intake.

The effect of dietary conjugated linoleic acid (CLA) in association with two vegetable oil sources on the fatty acids of meat and giblets of broiler chickens was evaluated. Two hundred 21-day-old broiler chickens were distributed in a completely randomized factorial design 2 x 5 (two oil sources, soybean or canola oil; and five levels of CLA, 0.0, 2.5, 5.0, 7.5, and 10.0g/kg). The addition of CLA to the diet resulted in an increase (P<0.05) in CLA deposition in the analyzed tissues. CLA supplementation also reduced (P<0.05) the rate of polyunsaturated to saturated fatty acids in thigh, breast, heart, and gizzard. There was interaction of CLA x oil source (P<0.05). The intake of soybean oil, associated with increasing CLA, resulted in an increase in lipid deposition in edible portions as observed by an increase in the overall content of fatty acids, including CLA, while the use of canola oil, associated with increasing CLA in the diet, resulted in a decrease in lipid content in edible portions, specifically regarding that of saturated fat (P<0.05) in breast meat and liver and in the content of monounsaturated fatty acids (P<0.05) in thigh, breast, liver, and gizzard.

This review article considers the role of fatty acids and the mutual association of their long-chain (e.g. C18) alkyl and alkenyl groups in some important aspects of papermaking. In particular, published findings suggest that interactions involving fatty acids present as condensed monolayer films can play a controlling role in pitch deposition problems. Self-association among the tails of fatty acids and their soaps also helps to explain some puzzling aspects of hydrophobic sizing of paper. When fatty acids and their soaps are present as monolayers in papermaking systems, the pH values associated with their dissociation, i.e. their pKa values, tend to be strongly shifted. Mutual association also appears to favor non-equilibrium multilayer structures that are tacky and insoluble, possibly serving as a nucleus for deposition of wood extractives, such, as resins and triglyceride fats, in pulp and paper systems.

ABSTRAK      Penelitian ini bertujuan untuk menyelidiki pengaruh dari pemberian pakan yang mengandung mikroenkapsulasi minyak kanola pada konsumsi, kecernaan nutrien, dan performa pertumbuhan pada domba. Lima belas domba garut jantan dengan rataan bobot badan awal 20.17 ± 4.65 kg digunakan dalam rancangan acak kelompok (RAK) pada periode pemeliharaan selama 100 hari dengan 3 perlakuan dan 5 kelompok sebagai ulangan. Perlakuan yang digunakan adalah P0 (kontrol / hijauan: konsentrat = 60:40), P1 (P0 mengandung 4% minyak kanola), dan P2 (P0 mengandung 4% mikroenkapsulasi minyak kanola). Hasil yang diperoleh dalam penelitian ini menunjukkan bahwa tidak ada perbedaan untuk performa, konsumsi dan kecernaan nutrien. Suplementasi minyak kanola murni maupun terenkapsulasi sebagai sumber energi dalam ransum domba, menghasilkan pertambahan bobot badan harian (PBBH) dan efisiensi penggunaan pakan yang terbaik. Proporsi asam lemak tak jenuh pada perlakuan suplementasi mikroenkapsulasi minyak kanola 8% lebih tinggi dibandingkan dengan kontrol. Perlakuan minyak kanola murni meningkatkan (P<0.05) proporsi asam stearat (C18:0) dibandingkan perlakuan lainnya. Sehingga, dapat disimpulkan bahwa suplementasi 4% mikroenkapsulasi minyak kanola di dalam ransum, selaian menghasilkan PBBH dan efisiensi pakan terbaik juga mampu melindungi asam lemak tak jenuh (ALTJ) dari proses biohidrogenasi rumen tanpa mengganggu konsumsi dan kecernaan nutrient ransum.Kata kunci: konsumsi, kecernaan, mikroenkapsulasi, minyak kanola, performaABSTRACTThe aim of this study was to investigate the effects of feeding diets with microencapsulation of canola oil on intake, nutrient apparent digestibility, and growth performance of lambs. Fifteen male garut lambs with an initial average body weight of 20.17 ± 4.65 kg were used in a randomized block design (RBD) for a 100-days feeding period with 3 treatments and 5 groups as replication. The treatments were P0 (control/forage:concentrate = 60:40), P1 (P0 contained 4% of canola oil), and P2 (P0 contained 4% of microencapsulated canola oil). The results showed that there was no difference in the growth performance, intake, and digestibility of nutrients. The best of average daily gain (ADG) and feed efficiency results from the supplementation of pure canola oil or encapsulated canola oil in diets. The proportion of unsaturated fatty acids in the supplementation of microencapsulated canola oil treatment was 8% higher than control. The treatment of canola oil supplementation increased (P<0.05) the proportion of stearic acid (C18:0) compared to other treatments. Thus, it can be concluded that supplementation of 4% of microencapsulated canola oil, besides produced the best of ADG and feed efficiency, was also able to maintain unsaturated fatty acids from the rumen biohydrogenation process without detrimental effects on nutrient intake and digestibility in lambs.    Keywords: canola oil, digestibility, intake, microencapsulation, performance

Special Arrangement

A new procedure is given to isolate the components that constitute the translucent lines present in some layered plant cuticles. These electron-translucent lines are mainly composed of fatty acids and n-alkanes. This waxy material is capable to form molecular bilayers with a constant thickness of approximately 5 nm. This special arrangement have a strong contribution in water transport across the cuticle
