The disadvantages of hydrogenating fats and oils is that the human body cannot use trans fats in the same manner it uses natural unsaturated fats. Also trans fats raises the levels of LDL cholesterol in the blood.
Trans-fatty acids may form in partial hydrogenation. These trans fatty-acids are poor energy sources which are difficult to metabolize, increases LDL levels, accumulate in fatty tissue and hard to digest.
what are the disadvantages of rancidity in fats and oils?
feels good but can get a sti
Fats turn into an "oil" when they melt.
no
lipids
glycerin is the by-product
Lipids are fats such as waxes, hormones, and oils.
we can check rancidity thru two methods :- check the smell usually it becomes foul and see if the the fats and oils are oxidized ,if yes then it is rancidity.
Rancidity means having a rank, unpleasant, stale smell or taste, as through decomposition, especially of fats or oils.
For example degradation -by the oxidation of fats, fatty acids, and edible oils- of lard, butter, saussage, etc.
Fats such as butter and oils become rancid as they oxidize or "go bad" over time. Rancid oils or foods have a nasty, pugnant, acrid taste that lingers in your mouth.

The healthiest oils are oils that have polyunsaturated and monounsaturated fats. The healthiest oils are oils packed with saturated fats.
Lipids are commonly called fats and oils.
Peroxide Value is one of the most widely used tests for oxidative rancidity in oils and fats, peroxide value is a measure of the concentration of peroxides and hydroperoxides formed in the initial stages of lipid oxidation. Milliequivalents of peroxide per kg of fat are measured by titration with iodide ion. Peroxide values are not static and care must be taken in handling and testing samples. It is difficult to provide a specific guideline relating peroxide value to rancidity. High peroxide values are a definite indication of a rancid fat, but moderate values may be the result of depletion of peroxides after reaching high concentrations.
The fats, oils, and waxes found in living things are known as lipids.
unsaturated fats
A molecule that is found in oils and fats is triglycerides.
