Elaidic acid is a trans fat with negative health effects. Full hydrogenation results in the conversion of all of the unsaturated fats into saturated fats by transforming all of the double bonds in the fat into single bonds. Partial hydrogenation reduces some, but not all, of the double bonds by the partial replacement with single bonds.
In contrast, it is now well-established that consumption of trans fats, such as those present in partially hydrogenated vegetable oils, are a risk factor for cardiovascular disease. Fats that are good for one may be turned into trans fats by improper cooking methods that result in overcooking the lipids. [95] [96] [97]
When it is fully hydrogenated, its profile is 94% saturated fat and 2% unsaturated fatty acids (1.5% monounsaturated, and 0.5% polyunsaturated). [4] According to the National Cottonseed Products Association, cottonseed oil does not need to be hydrogenated as much as other polyunsaturated oils to achieve similar results. [2]
The production of hydrotreated vegetable oils is based on introducing hydrogen molecules into the raw fat or oil molecule. This process is associated with the reduction of the carbon compound. When hydrogen is used to react with triglycerides, different types of reactions can occur, and different resultant products are combined. [ 1 ]
According to the NOVA classification system, ultra-processed foods are industrial formulations made entirely or mostly from substances extracted from foods (oils, fats, sugar, starch, and proteins ...
Monoglycerides and diglycerides are types of glycerides both naturally present in food fats, [2] including various seed oils; [3] however, their concentration is usually low and industrial production is primarily achieved by a glycerolysis reaction between triglycerides (fats/oils) and glycerol, [4] followed by purification via solvent-free molecular distillation.
This template tabulates data of composition of various vegetable oils, their processing treatments (whether unrefined, hydrogenated or partially hydrogenated) and their smoke point The above documentation is transcluded from Template:Vegetable oils comparison/doc .
The FDA banned the addition of hydrogenated oils to packaged foods in 2018 so you shouldn't find them in packaged foods anymore, but trans fats are also found naturally in some cooking oils used ...
