Pecan Oil
Pecan oil is an edible pressed oil extracted from the pecan nut. Pecan oil is neutral in flavor and tastes of whatever seasoning is being used with it. Pecan oil contains 9.5% saturated fat, which is less than in olive oil (13.5%), peanut oil (16.90%) or corn oil (12.70%). It is also used as a massage oil and in aromatherapy applications. Pecan oil is considered a healthy oil as it is rich in monounsaturated fats, specifically oleic acid, (52.0%) and low in saturated fats. It also contains linoleic acid (36.6%), and small amounts of palmitic (7.1%), stearic (2.2%) and linolenic acids (1.5%). The overall balance of fatty acids in the oil may reduce LDL cholesterol (also known as "bad" cholesterol) and the risk of heart disease. The main application of this oil is its use in cooking. It has a high smoke point of 470 degrees F making it ideal for cooking at high temperatures and for deep frying. The mild nutty taste enhances the flavor of other ingredients, making it a popular comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olive Oil From Oneglia
The olive, botanical name ''Olea europaea'' ("European olive"), is a species of subtropical evergreen tree in the family Oleaceae. Originating in Asia Minor, it is abundant throughout the Mediterranean Basin, with wild subspecies in Africa and western Asia; modern cultivars are traced primarily to the Near East, Aegean Sea, and Strait of Gibraltar. The olive is the type species for its genus, ''Olea'', and lends its name to the Oleaceae plant family, which includes species such as lilac, jasmine, forsythia, and ash. The olive fruit is classed botanically as a drupe, similar to the cherry or peach. The term oil—now used to describe any viscous water-insoluble liquid—was virtually synonymous with olive oil, the liquid fat made from olives. The olive has deep historical, economic, and cultural significance in the Mediterranean; Georges Duhamel remarked that the "Mediterranean ends where the olive tree no longer grows". Among the oldest fruit trees domesticated by huma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linoleic Acid
Linoleic acid (LA) is an organic compound with the formula . Both alkene groups () are ''cis''. It is a fatty acid sometimes denoted 18:2 (n−6) or 18:2 ''cis''-9,12. A linoleate is a salt or ester of this acid. Linoleic acid is a polyunsaturated, omega−6 fatty acid. It is a colorless liquid that is virtually insoluble in water but soluble in many organic solvents. It typically occurs in nature as a triglyceride (ester of glycerin) rather than as a free fatty acid. It is one of two essential fatty acids for humans, who must obtain it through their diet, and the most essential, because the body uses it as a base to make the others. The word "linoleic" derives , reflecting the fact that it was first isolated from linseed oil. History In 1844, F. Sacc, working at the laboratory of Justus von Liebig Justus ''Freiherr'' von Liebig (12 May 1803 – 18 April 1873) was a Germans, German scientist who made major contributions to the theory, practice, and pedagogy of che ...

Vegetable Oils
Vegetable oils, or vegetable fats, are oils extracted from seeds or from other parts of edible plants. Like animal fats, vegetable fats are ''mixtures'' of triglycerides. Soybean oil, grape seed oil, and cocoa butter are examples of seed oils, or fats from seeds. Olive oil, palm oil, and rice bran oil are examples of fats from other parts of plants. In common usage, vegetable ''oil'' may refer exclusively to vegetable fats which are liquid at room temperature. Vegetable oils are usually edible. History In antiquity Olive oil has been a part of human culture for millennia.Ruth Schuster (December 17, 2014). "8,000-year old olive oil found in Galilee, earliest known in world", ''Haaretz''. Retrieved December 17, 2014. Archaeological evidence shows that olives were turned into olive oil by 6000 BC and 4500 BC in present-day Israel. Pagnol, p. 19, says the 6th millennium in Jericho, but cites no source. In ancient Egypt, plant oils including cedar oil, cypress oil, and ol ...

Butter
Butter is a dairy product made from the fat and protein components of Churning (butter), churned cream. It is a semi-solid emulsion at room temperature, consisting of approximately 81% butterfat. It is used at room temperature as a spread (food), spread, melted as a condiment, and used as a Cooking fat, fat in baking, sauce-making, pan frying, and other cooking procedures. Most frequently made from cow's milk, butter can also be manufactured from the milk of other mammals, including Sheep milk, sheep, Goat milk, goats, Buffalo milk, buffalo, and Yak milk, yaks. It is made by churning milk or cream to separate the fat globules from the buttermilk. Dairy salt, Salt has been added to butter since antiquity to help Food preservation, preserve it, particularly when being transported; salt may still play a preservation role but is less important today as the entire supply chain is usually refrigerated. In modern times, salt may be added for taste and food coloring added for color. Kit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salad Dressing
A salad dressing is a sauce for salads, used on virtually all leafy salads. Dressings may also be used in preparing salads of beans (e.g., three bean salad), noodle or pasta salads and antipasti, and forms of potato salad. A dressing may even be made for fruit salads. Salad dressings can be drizzled over a salad, added and tossed with the ingredients, or offered "on the side". The functionality of some of these sauces has been extended, meaning they can be served as a dip (as with '' crudités'' or chicken wings). Types In Western culture, there are two basic types of salad dressing: * Vinaigrettes based on a mixture (emulsion) of olive or salad oil and vinegar, and variously flavored with herbs, spices, salt, pepper, sugar, and other ingredients, such as poppy seeds or ground Parmesan cheese. * Creamy dressings, usually based on mayonnaise or fermented milk products, such as yogurt, sour cream ( crème fraîche, smetana) or buttermilk. In the United States, buttermilk-b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smoke Point
The smoke point, also referred to as the burning point, is the temperature at which an oil or fat begins to produce a continuous bluish smoke that becomes clearly visible, dependent upon specific and defined conditions. This happens when one or multiple substances in the oil start to chemically react with oxygen and burn, which can include the oil itself, proteins, sugars, or other organic material. It is distinct from the flash point and fire point, which denote the temperatures at which the oil itself (specifically, vaporized oil, which is distinct from the smoke produced at the smoke point) begins to burn. Smoke point values can vary greatly. The most important factor determining the smoke point of an oil is the amount of proteins and free fatty acids (FFAs). Higher quantities of these lower the smoke point. The FFA content typically represents less than 1% of the total oil and consequently renders smoke point a poor indicator of the capacity of a fat or oil to withstand h ...

Heart Disease
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina pectoris, angina, myocardial infarction, heart attack), heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease, Thrombosis, thromboembolic disease, and venous thrombosis. The underlying mechanisms vary depending on the disease. It is estimated that dietary risk factors are associated with 53% of CVD deaths. Coronary artery disease, stroke, and peripheral artery disease involve atherosclerosis. This may be caused by hypertension, high blood pressure, tobacco smoking, smoking, diabetes mellitus, lack of physical exercise, exercise, obesity, hypercholesterolaemia, high blood cholesterol, poor diet, excessive alcoholic beverage, alcohol consumption, and poor sleep, amo ...

LDL Cholesterol
Low-density lipoprotein (LDL) is one of the five major groups of lipoprotein that transport all fat molecules around the body in extracellular water. These groups, from least dense to most dense, are chylomicrons (aka ULDL by the overall density naming convention), very low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL), low-density lipoprotein (LDL) and high-density lipoprotein (HDL). LDL delivers fat molecules to cells. LDL has been associated with the progression of atherosclerosis. Overview Lipoproteins transfer lipids (fats) around the body in the extracellular fluid, making fats available to body cells for receptor-mediated endocytosis. Lipoproteins are complex particles composed of multiple proteins, typically 80–100 proteins per particle (organized by a single apolipoprotein B for LDL and the larger particles). A single LDL particle is about 22–27.5 nanometers in diameter, typically transporting 3,000 to 6,000 fat molecules per particle and v ...

Fatty Acids
In chemistry, in particular in biochemistry, a fatty acid is a carboxylic acid with an aliphatic chain, which is either saturated or unsaturated. Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28. Fatty acids are a major component of the lipids (up to 70% by weight) in some species such as microalgae but in some other organisms are not found in their standalone form, but instead exist as three main classes of esters: triglycerides, phospholipids, and cholesteryl esters. In any of these forms, fatty acids are both important dietary sources of fuel for animals and important structural components for cells. History The concept of fatty acid (''acide gras'') was introduced in 1813 by Michel Eugène Chevreul, though he initially used some variant terms: ''graisse acide'' and ''acide huileux'' ("acid fat" and "oily acid"). Types of fatty acids Fatty acids are classified in many ways: by length, by saturation vs unsat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oleic Acid
Oleic acid is a fatty acid that occurs naturally in various animal and vegetable fats and oils. It is an odorless, colorless oil, although commercial samples may be yellowish due to the presence of impurities. In chemical terms, oleic acid is classified as a monounsaturated omega-9 fatty acid, abbreviated with a lipid number of 18:1 ''cis''-9, and a main product of Δ9-desaturase. It has the formula . The name derives from the Latin word '' oleum'', which means oil. It is the most common fatty acid in nature. The salts and esters of oleic acid are called oleates. It is a common component of oils, and thus occurs in many types of food, as well as in soap. Occurrence Fatty acids (or their salts) often do not occur as such in biological systems. Instead fatty acids such as oleic acid occur as their esters, commonly triglycerides, which are the greasy materials in many natural oils. Oleic acid is the most common monounsaturated fatty acid in nature. It is found in fats (trigl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cooking Oil
Cooking oil (also known as edible oil) is a plant or animal liquid fat used in frying, baking, and other types of cooking. Oil allows higher cooking temperatures than water, making cooking faster and more flavorful, while likewise distributing heat, reducing burning and uneven cooking. It sometimes imparts its own flavor. Cooking oil is also used in food preparation and flavoring not involving heat, such as salad dressings and bread dips. Cooking oil is typically a liquid at room temperature, although some oils that contain saturated fat, such as coconut oil, palm oil and palm kernel oil are solid. There are a wide variety of cooking oils from plant sources such as olive oil, palm oil, soybean oil, canola oil ( rapeseed oil), corn oil, peanut oil, sesame oil, sunflower oil and other vegetable oils, as well as animal-based oils like butter and lard. Oil can be flavored with aromatic foodstuffs such as herbs, chilies or garlic. Cooking spray is an aerosol of coo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monounsaturated
In biochemistry and nutrition, a monounsaturated fat is a fat that contains a monounsaturated fatty acid (MUFA), a subclass of fatty acid characterized by having a double bond in the fatty acid chain with all of the remaining carbon atoms being single-bonded. By contrast, polyunsaturated fatty acids (PUFAs) have more than one double bond. Molecular description Monounsaturated fats are triglycerides containing one unsaturated fatty acid. Almost invariably that fatty acid is oleic acid (18:1 n−9). Palmitoleic acid (16:1 n−7) and cis-vaccenic acid (18:1 n−7) occur in small amounts in fats. Health Studies have shown that substituting dietary monounsaturated fat for saturated fat is associated with increased daily physical activity and resting energy expenditure. More physical activity was associated with a higher-oleic acid diet than one of a palmitic acid diet. From the study, it is shown that more monounsaturated fats lead to less anger and ...
