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.
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 ...
Generally, however, these guidelines agree that highly processed foods contain high amounts of total and added sugars, fats, and/or salt, low amounts of dietary fiber, use industrial ingredients ...
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]
A higher melting point is desirable in these warm climates, so the oil is hydrogenated. The melting point of hydrogenated coconut oil is 36–40 °C (97–104 °F). In the process of hydrogenation, unsaturated fats (monounsaturated and polyunsaturated fatty acids) are combined with hydrogen in a catalytic process to make them more saturated.
Concern about the health hazards of hydrogenated fats (trans fats) is a contributor to the declining popularity of Copha-based confectionery. [4] In New Zealand, it is marketed as Kremelta. Known in Europe as coconut fat, it is available either in its pure form, or in solid form with lecithin added as an emulsifier.
Since 2010, vegetable oils and fats sold to consumers directly must contain only 2% of trans fat over total fat, and other food must contain less than 5% of their total fat. [9] Starting on 10 December 2014, Argentina has on effect a total ban on food with trans fat, a regulation that could save the government more than US$100 million a year on ...
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 ]
