In refining, the chemical addition of hydrogen to a hydrocarbon in the presence of a catalyst; a severe form of hydrogen treating. Hydrogenation may be either destructive or non-destructive. In the fo [..]

Hydrogenation is a reduction reaction which results in an addition of hydrogen (usually as H2). If an organic compound is hydrogenated, it becomes more 'saturated'. Hydrogenation has m [..]

Addition of one or more hydrogens to monunsaturated and polyunsaturated fatty acid chains. hydrogenosomes

A process that changes an unsaturated fat to a more saturated one.

The process of hardening an unsaturated fat by adding hydrogen atoms to an unsaturated fat molecule. This enables the fat to remain solid at room temperature. Margarine is a good example.

Process of adding hydrogen molecules directly to an unsaturated fatty acid from sources such as vegetable oils to convert it to a semi-solid form such as margarine or shortening. Hydrogenation contributes important textural properties to food. The degree of hydrogenation influences the firmness and spreadability of margarines, flakiness of pie crus [..]

A commercial process in which hydrogen atoms are added to the double bonds in unsaturated fatty acids to make them more saturated. Hydrogenation can change liquid fats into solid fats. Commercial shor [..]

(n) a chemical process that adds hydrogen atoms to an unsaturated oil

The addition of hydrogen to a compound. Hydrogenation is used to solidify liquid vegetable oils. The process creates trans fats, which are harmful to the heart and blood vessels.

the infusing of unsaturated or impure hydrocarbons with hydrogen gas at controlled temperatures and pressures for the purpose of obtaining saturated hydrocarbons and/or removing various impurities suc [..]

Addition of Hydrogen to a compound, especially to an unsaturated fat or fatty acid. (From Stedman, 26th ed)

Addition of hydrogen to a compound, especially to an unsaturated fat or fatty acid. (From Stedman, 26th ed)

The process for transforming an oil (unsaturated liquid fat) into a hard fat by incorporating hydrogen. Hydrogentaed fat is similar to saturated fat and linked to an increased risk of heart disease.

Converting oils to another physical state is most often accomplished by adding hydrogen to vegetable oil. The process is called Hydrogenation. The resultant solid trans fats are less likely to spoil a [..]

– The addition of hydrogen atoms to a compound, usually an organic compound.

hahy-druh-juh-neyt-shuhn Reacting coal with hydrogen at high pressures, usually in presence of a catalyst.

A refinery process in which hydrogen is added to the molecules of unsaturated hydrocarbon fractios.

 a reaction in which hydrogen is added to a chemical, for example, in the conversion of unsaturated fats to saturated fats. Top IARC:

is a chemical process which makes liquid oils more saturated and solid. This process not only increases the amount of saturated fat in the oil, but also produces trans fats (see below). Hydrogenated f [..]

The process in which unsaturated fatty acids are saturated with hydrogen atoms to make them more solid.

(chemistry) the chemical reaction of hydrogen with another substance, especially with an unsaturated organic compound, and usually under the influence of temperature, pressure and catalysts.

A chemical way to turn liquid fat (oil) into solid fat. This process creates a new fat called trans fatty acids. Trans fatty acids are found in margarine, shortening, and some commercial baked foods like cookies, crackers, muffins, and cereals. Eating a large amount of trans fatty acids may raise heart disease risk.
