It does not seem possible to memorize 600+ names, including every name on this list, in order to read labels and avoid purchasing products containing these ingredients/derivatives. A more responsible course of action is to support RSPO member companies and sustainable palm oil production instead! For more information go to www.cmzoo.org/palmoil Revised September 2020 .

Oleochemicals Series
OLEOCHEMICALS FATTY ACIDS This section will concentrate on Fatty Acids produced from natural fats and oils (i.e. not those derived from petroleum products). Firstly though, we will recap briefly on Nomenclature. We spent some time clarifying the structure of oleochemicals and we saw how carbon atoms link together to form carbon chains of varying length (usually even numbered in nature, although animal fats from ruminant animals can have odd-numbered chains). A fatty acid has at least one carboxyl group (a carbon attached to two oxygens (-O) and a hydrogen (-H), usually represented as -COOH in shorthand) appended to the carbon chain (the last carbon in the chain being the one that the oxygen and hydrogen inhabit). We will only be talking about chains with one carboxyl group attached (generally called “monocarboxylic acids”). The acids can be named in many ways, which can be confusing, so we will try and keep it as simple as possible. The table opposite shows the acid designations as either the “length of the carbon chain” or the “common name”. While it is interesting to know the common name for a particular acid, we will try to use the chainlength in any discussion so you do not have to translate. Finally, it is usual to speak about unsaturated acids using their chainlength suffixed with an indication of the number of double bonds present. Thus, C16=1 is the C16 acid with one double bond; C18=2 is the C18 acid with two double bonds and so on. SELECTING RAW MATERIALS FOR FATTY ACID PRODUCTION In principle, fatty acids can be produced from any oil or fat by hydrolytic or lipolytic splitting (reaction with water using high pressure and temperature or enzymes).

April 9, 2020 Replacement of Primex Brand Hydrogenated Vegetable
April 9, 2020 Replacement of Primex Brand Hydrogenated Vegetable Shortening In June of 2018 the FDA banned the use of trans fats in human foods. Due to the ban, Envigo was no longer able to source Primex brand hydrogenated vegetable oil (HVO) containing trans fats. Beginning on April 11th of 2018, Primex was replaced with an USP grade HVO made to a food-grade standard that has a similar texture and fatty acid profile (see table). Manufacturing tests revealed no appreciable differences in physical qualities of finished diets. Although diet numbers did not change, you may have noticed an updated diet title and ingredient description on the diet datasheet. Depending on your research goals and desire for relevance to human diets, you may wish to use a source of HVO without trans fats such as Crisco. Crisco is a proprietary HVO with minimal trans fats (see table). Envigo also offers several popular obesity inducing diets with alternate fat sources like lard or milkfat that may be suitable for your research. Contact a nutritionist to discuss alternate options. Comparison of the fatty acid profile of Primex, Envigo Teklad’s Replacement HVO and Crisco.

About Trans Fat and Partially Hydrogenated Oils Q. What Is Trans
About Trans Fat and Partially Hydrogenated Oils Q. What is trans fat? A. Most trans fat is a monounsaturated (one double bond) fatty acid. The shape of trans-fat molecules is more like cholesterol-raising saturated fat than a typical monounsaturated fatty acid. Perhaps for that reason, it increases cholesterol levels in blood and increases the risk of heart disease. Q. Where does trans fat come from? A. According to the Food and Drug Administration (FDA), in 1994-96 we consumed about 5.6 grams of trans fat per day. Most of that trans fat comes from the 40,000-plus foods that contain partially hydrogenated vegetable oil. Those include many stick margarines, biscuits, pastries, cookies, crackers, icings, and deep-fried foods at restaurants. Because Frito-Lay, margarine producers, and some other companies recently stopped using (or cut back on the use of) partially hydrogenated oils, we now are consuming a little less trans fat. About one-fifth (1.2 g) of the trans fat came from natural sources, especially beef and milk products (bacteria in cattle produce trans fat that gets into meat and milk). A little more occurs naturally in vegetable oils and forms when vegetable oils are purified. Q. How is partially hydrogenated oil made? A. To convert soybean, cottonseed, or other liquid oil into a solid shortening, the oil is heated in the presence of hydrogen and a catalyst. That hydrogenation process converts some polyunsaturated fatty acids to monounsaturated and saturated fatty acids. It also converts some monounsaturated fatty acids to saturated fatty acids. Thus, a healthful oil is converted into a harmful one.

Abstract: Thermal energy storage is known as a key element to optimize the use of renewable energies and to improve building performances. Phase change materials (PCMs) derived from wastes or by-products of plant or animal oil origins are low-cost biosourced PCMs and are composed of more than 75% of fatty acids. They present parafﬁn-like storage properties and melting temperatures ranging from −23 ◦C to 78 ◦C. Therefore, they could be appropriate for latent heat storage technologies for building applications. Although already studied, a more detailed exploration of this class of PCMs is still required. In this frame, a screening of fatty acids and of their related binary systems must be performed.

Omega-3, Omega-6 and Omega-9 Fatty Acids
Johnson and Bradford, J Glycomics Lipidomics 2014, 4:4 DOI: 0.4172/2153-0637.1000123 Journal of Glycomics & Lipidomics Review Article Open Access Omega-3, Omega-6 and Omega-9 Fatty Acids: Implications for Cardiovascular and Other Diseases Melissa Johnson1* and Chastity Bradford2 1College of Agriculture, Environment and Nutrition Sciences, Tuskegee University, Tuskegee, Alabama, USA 2Department of Biology, Tuskegee University, Tuskegee, Alabama, USA Abstract The relationship between diet and disease has long been established, with epidemiological and clinical evidence affirming the role of certain dietary fatty acid classes in disease pathogenesis. Within the same class, different fatty acids may exhibit beneficial or deleterious effects, with implications on disease progression or prevention. In conjunction with other fatty acids and lipids, the omega-3, -6 and -9 fatty acids make up the lipidome, and with the conversion and storage of excess carbohydrates into fats, transcendence of the glycome into the lipidome occurs. The essential omega-3 fatty acids are typically associated with initiating anti-inflammatory responses, while omega-6 fatty acids are associated with pro-inflammatory responses. Non-essential, omega-9 fatty acids serve as necessary components for other metabolic pathways, which may affect disease risk. These fatty acids which act as independent, yet synergistic lipid moieties that interact with other biomolecules within the cellular ecosystem epitomize the critical role of these fatty acids in homeostasis and overall health. This review focuses on the functional roles and potential mechanisms of omega-3, omega-6 and omega-9 fatty acids in regard to inflammation and disease pathogenesis. A particular emphasis is placed on cardiovascular disease, the leading cause of morbidity and mortality in the United States.

Udeh Medical Biochemistry Department, University of Port Harcourt, Port Harcourt [email protected] Dr. Jude Obibuzor Biochemistry Division, Nigerian institute for Oil palm Research Benin ABSTRACT Eight samples of Elaeis oleifera palm oil milled from fresh fruit bunches harvested from different NIFOR oil palm fields were analyzed to determine their physical and chemical properties in comparison to the properties of the normal palm oil Elaeis guineensis mainly milled by the institute. Analyses conducted included palatability test, determination of the free fatty acid values of the samples, determination of their peroxide values and their moisture contents. Results obtained showed evidences of disparity in chemical properties and slight physical differences between the two species of palm. The average free fatty acid value of the samples was 0.76% as against 0.85% of the normal Elaeis guineensis. Also, the average peroxide value of the samples was 3.83% meg/kg as against that of E. guineensis which was 4.26meg/kg while the average % moisture content of the samples was 0.47% and that of E. guineesis 0.51%. The iodine value (wijs) of the samples was 88.50 and that of E. guineensis 60.80. Beta-ketoacyl ACP synthase II enzyme activity were also determined in the sample and was 7.51 as against 2.15 in E. guineensis. The E.
