Not exact matches

The ORNL - led study instead provides evidence for the second mechanism, in which one H atom associates with an O atom to make OH and the other H associates with cerium (Ce) to make CeH — a hydride that may serve as a source of H for industrially important hydrogenation reactions.

Based on the analysis, the first ice formation phase is driven by hydrogenation of atoms, which results in a H2O - dominated ice.

Trans fats are fatty acids formed through a chemical process called hydrogenation in which hydrogen is added to liquid vegetable oils to make them solid.

The fatty acids known as trans fats are made through a chemical process called hydrogenation which solidifies their oils to ensure a longer shelf - life in the grocery store.

Transfats and partially hydrogenated oils (which are one and the same thing) are regular vegetable oils like soybean oil that undergoes a process called hydrogenation, which is the addition of hydrogen atoms to the molecular structure of fats.

Hydrogenation needs a catalyst, so a substance called Raney nickel can be used which is a powdered nickel - aluminium alloy.

In 1907 candle - maker William Procter and soap - maker James Gamble needed a use for cheap cottonseed oil, a waste product of the cotton mills they owned, and developed the process of hydrogenation, which turned the liquid oil into a solid resembling lard.

Starch is first hydrolyzed into short chain sugars, which are then hydrogenation under pressure and temperature into sugar alcohols.

Trans fat a side effect of hydrogenation, which is a form of processing our foods in the food industry to make them a sustainable shelf life.

Trans fats are artificially created through a process called hydrogenation, which uses hydrogen, pressure and heat to change the chemical structure of vegetable oils from liquid to semi-solid.

Look particularly for the Unsweetened Organic Sun Butter, which is made without hydrogenation and also contains that natural layer of oil on the top of the jar.

Consumers will obtain isomerized essential fatty acids from vegetable oils currently marketed in the U. S... A large portion of canola oil used in processed food has been hardened through the hydrogenation process, which introduces levels of trans fatty acids into the final product as high as 40 percent (9).

Hydrogenation adds another layer of processing which turns the oil into a solid at room temperature, and creates trans - fatty - acids, which experts agree are extremely unhealthy, and should be avoided at all costs.

Partially hydrogenated margarines and shortenings are even worse for you than the highly refined vegetable oils from which they are made because of chemical changes that occur during the hydrogenation process.

Unnatural fats, like margarine, shortenings and spreads are formed during the process of partial hydrogenation, which turns liquid vegetable oil into a solid fat.

Hydrogenation involves high heat and pressure treatment, which is bad news for the fat molecules and for your body.

Hydrogenation leads to the generation of fatty acids with a single trans bond, which block our body's enzymes.

One method is hydrogenation, which creates a partially hydrogenated, solid fat.

A large portion of canola oil used in processed food has been hardened through the hydrogenation process, which introduces levels of trans fatty acids into the final product as high as 40 percent.25 In fact, canola oil hydrogenates beautifully, better than corn oil or soybean oil, because modern hydrogenation methods hydrogenate omega - 3 fatty acids preferentially and canola oil is very high in omega - 3s.

But they do harbor some saturated fat in the form of stearic acid, which is created during the hydrogenation process.

Partial hydrogenation reduces the levels of polyunsaturated oils — and also creates trans fats, which promote heart disease.

Hydrogenation: Makes fats & oils more solid and enables higher heating temperatures which increases shelf life.

Besides the possibility of our applying a similar process to the bituminous coal and tars made therefrom, in this country, the research on hydrogenation has been extended by one of the great oil companies of the United States which at great expense has learned how the method can be so modified as to apply to petroleum hydrocarbons.
