hydrogenation
The reaction in which hydrogen adds across a double or triple bond
A process employed to alter the chemical, and usually, the physical properties if a fat Generally speaking, hydrogenation is used to change a liquid oil into a semisolid or solid fat at ambient temperatures to enhance oxidative stability
Chemical reaction between molecular hydrogen (H2) and another element or a compound, usually in the presence of a catalyst. It may involve adding hydrogen at the sites of double or triple bonds (see bonding) to make them single bonds (i.e., to saturate an unsaturated compound; see saturation), or to aromatic compounds to make them cyclic hydrocarbons. Edible oils with unsaturated fatty acids are liquid at room temperature; food manufacturers use hydrogenation to convert a fraction to saturated fatty acids to make the product more solid. A second type of hydrogenation involves breaking up a compound (hydrogenolysis, or destructive hydrogenation) and is of great importance in the petroleum industry. Numerous processes in gasoline and petrochemical manufacturing are based on it
{i} process of treating with hydrogen (Chemistry)
Process in which manufacturers change a liquid fat into a solid fat These solid fats are saturated fats that tend to raise the blood cholesterol level
(high-dro-jen-AY-shun) 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
a chemical process that adds hydrogen atoms to an unsaturated oil; "food producers use hydrogenation to keep fat from becoming rancid"
A process used to harden unsaturated liquid vegetable oils into saturated fats
(high-dro-jen-AY-shun)
The act of combining with hydrogen, or the state of being so combined
A process in which vegetable oils have been artificially hardened, making them more like a saturated fat
a chemical process that converts liquid fats to solid fats
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 former case, hydrocarbon chains are ruptured (cracked) and hydrogen is added where the breaks have occurred In the latter, hydrogen is added to a molecule that is unsaturated (see unsaturated hydrocarbon) with respect to hydrogen In either case, the resulting molecules are highly stable Temperature and pressures in the hydrogenation process are usually greater than hydrofinishing
the chemical reaction of hydrogen with another substance, especially with an unsaturated organic compound, and usually under the influence of temperature, pressure and catalysts
-the process of adding hydrogen to unsaturated fatty acids in order to make them harder Many processed foods are hydrogenated, making them potentially unhealthy
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 such as sulfur and nitrogen
The chemical addition of hydrogen to a material In non-destructive hydrogenation, hydrogen is added to a molecule only if, and where, unsaturation with respect to hydrogen exists In destructive hydrogenation, the operation is carried out under conditions which result in rupture of some of the hydrocarbon chains (cracking); hydrogen is added where the chain breaks have occurred
Hydrogenation is a chemical reaction that adds hydrogen atoms to an unsaturated fat thus saturating it and making it solid at room temperature
the addition of hydrogen to the double bonds of polyunsaturated and monounsaturated fatty acids to reduce the extent of unsaturation; this process turns liquid vegetable oil into solid fats
