Riegel's Handbook of Industrial Chemistry pp Cite as. Fats and oils predominantly are triesters triacylglycerols TAG , triglycerides of glyecrol and aliphatic fatty acids containing up to 22 carbon atoms.
Waxes are esters of long-chain fatty acids, usually containing 24—28 carbon atoms, with long-chain primary alcohols 16—36 carbon atoms or with alcohols of the steroid group.
Fats and oils are members of a broader group of chemical substances called lipids , which has been classified by the National Research Council into: 1 nonpolar lipids —including esters of fatty acids triacylglycerols and cholesteryl esters that are virtually insoluble in water, but soluble in most organic solvents and enter metabolic pathways only after hydrolysis; and 2 polar or amphipathic lipids —including fatty acids, cholesterol, sphingolipids, and glycerolphospholipids mainly lecithins.

Functions of Fat in Food
Butter is made from the butterfat of milk, whereas modern margarine is made mainly of refined vegetable oil and water. In some places in the United States, it is colloquially referred to as oleo , short for oleomargarine. Due to its versatility, margarine can be used as an ingredient in other food products, such as pastries, doughnuts, cakes and cookies.
Due to dietary concerns, lard has gradually lost much of its former popularity. It is still extensively used, however, for:. Lard has a good plastic range, which enables it to be worked in a pie dough at fairly low temperatures try the same thing with butter! It has a fibrous texture and does not cream well. It is therefore not suitable for cake making.
17.2: Fats and Oils
These examples represent emulsions, which are stable mixtures of tiny droplets of one immiscible fluid within another, made possible by chemicals called emulsifiers. In both cases, emulsifiers are needed to prevent the suspended droplets from coalescing and breaking the emulsion. Anybody who has made a simple oil-and-vinegar salad dressing knows that, with enough shaking or whisking, one can make a temporary emulsion. However, in the absence of emulsifiers, this unstable emulsion breaks down within minutes, and the oil forms a layer on top of the vinegar. For centuries, cooks have added natural emulsifiers, such as egg yolk, mustard, or honey, to help prevent this separation. Today, a wide variety of nature-based and synthetic emulsifiers are available for the diverse fields that benefit from them, including food, nutraceuticals, home and personal care, biofuel, environmental cleanup, and industrial lubricant applications. Emulsifiers work by forming physical barriers that keep droplets from coalescing. A type of surfactant see Sidebar , emulsifiers contain both a hydrophilic water-loving, or polar head group and a hydrophobic oil-loving, or nonpolar tail. Therefore, emulsifiers are attracted to both polar and nonpolar compounds.
Specific oils and shortenings for food manufacturers
Fats and oils are the most abundant lipids in nature. They provide energy for living organisms, insulate body organs, and transport fat-soluble vitamins through the blood. Fats and oils are called triglycerides or triacylcylgerols because they are esters composed of three fatty acid units joined to glycerol , a trihydroxy alcohol:. If all three OH groups on the glycerol molecule are esterified with the same fatty acid, the resulting ester is called a simple triglyceride.
The moisture and fat content were 5—6. Descriptive sensory analysis revealed that the products had acceptability score of 8. Fat extracted from spreads prepared using M1 and M2 was found to contain
Trans Fat Replacements in Foods (pg.2)
Margarine : Is a spread used for spreading, baking, and cooking. Margarine is made mainly of hydrogenated or refined plant oils and water. While butter is made from fat from milk, margarine is made from plant oils and may also contain milk.
Manufacturers use the process of hydrogenation to create trans fats in order to increase the shelf life of baked and fried foods. Ingestion of trans fats is associated with an increased risk of cardiovascular disease. A groundswell of public sentiment is causing regulatory bodies to ban the use of trans fats in foods. Alternatives to trans fats are needed now in order to preserve the freshness and provide an appealing texture of many packaged foods. As trans fats become phased out, there are eight types of approaches currently being developed to substitute for these fats as ingredients for baked and fried foods: 1 modified hydrogenation, 2 genetically modified seeds, 3 interesterification, 4 fractionation and blending, 5 butter and animal fat, 6 natural saturated oils, 7 natural unsaturated oils, and 8 fat substitutes.

These guidelines are intended to provide a broad framework permitting the development of more specific group or individual standards, according to the requirements of individual countries. Fat spread: A fat spread is a food in the form of an emulsion mainly of the water-in-oil type , comprising principally an aqueous phase and edible fats and oils. Edible fats and oils: Foodstuffs mainly composed of triglycerides of fatty acids. They are of vegetable, animal, milk or marine origin. Tables
Good food requires good ingredients. VFI offers a wide range of oils and fats for all uses in the food industry, and for commercial consumers. The highest product safety and the best quality for raw materials are a given. Our research and development team is permanently working on innovative solutions for particular challenges.
Trans fat labeling became law in July Anon. Key provisions include the effective date for including trans fats as a separate line on nutrition labels was January 1, Another provision allows foods containing less than 0.
Fats and oils are not just a caloric powerhouse, but they also serve many chemical, physical, and nutritional functions in the foods we eat. Here are ten of the most important functions that fats serve in food. The ability of fat to refract light is also responsible for the opaque appearance of milk. Fats also aid in the browning process of many foods, giving them an appealing golden brown color.
We also look at palm oil scores, animal rights, shine a spotlight on Arla and give our recommended buys. This is a product guide from Ethical Consumer, the UK's leading alternative consumer organisation. Since we've been researching and recording the social and environmental records of companies, and making the results available to you in a simple format. Is it palm oil free? The palm oil industry is destroying a significant amount of tropical rainforests in Malaysia and Indonesia. Buying uncertified palm oil supports this practice. Look for spreads that are palm oil free or buy from companies that source only sustainable palm oil.
Dairy Science includes the study of milk and milk-derived food products, examining the biological, chemical, physical, and microbiological aspects of milk itself as well as the technological processing aspects of the transformation of milk into its various consumer products, including beverages, fermented products, concentrated and dried products, butter and ice cream. This new edition includes information on the possible impact of genetic modification of dairy animals, safety concerns of raw milk and raw milk products, peptides in milk, dairy-based allergies, packaging and shelf-life and other topics of importance and interest to those in dairy research and industry.
