There are two types of rancidity: oxidative rancidity and hydrolytic rancidity. Citric acid and phosphoric acid are added to prevent rancidity in fats. Other antioxidants include butylated hydroxyanisole (BHA)and butylated hydroxytoluene (BHT).
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.

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.
Fats can become rancid through long term storage, exposure to oxygen, exposure to light, exposure to metal, and holding them at high temperatures.Chemically is is oxidation of fat leading to decomposition.
Foods high in cholesterol, trans fats, and saturated fats, are bad for the heart and can cause chronic heart disease.
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.
For example degradation -by the oxidation of fats, fatty acids, and edible oils- of lard, butter, saussage, etc.
