For example degradation -by the oxidation of fats, fatty acids, and edible oils- of lard, butter, saussage, etc.
the types of rancidity are oxidative, microbial and hydrolytic...
Rancidity is the development of unpleasant flavors and odors in fats and oils as a result of chemical changes. There are two main types of rancidity: oxidative rancidity, which occurs when fats and oils react with oxygen, and hydrolytic rancidity, which occurs when fats and oils react with water.
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.
chemical reaction takes place in rancidity
Rancidity is caused by hydrolysis and oxidation. Heat, moisture and exposure to light will increase these chemical reactions and thus increase the likelikhood of the onset of rancidity.
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 could minimize rancidity by adding anti oxidents(which prevents oxidation) to food items.
rancidity food are very wasted food for our health because there oil and oil are faty

Rancidity occurs when fats or oils are exposed to oxygen, causing them to undergo oxidation. This process can be accelerated by heat, light, or the presence of certain enzymes or microbes. As fats oxidize, they develop off-flavors and odors, leading to a rancid taste.
Rancidity means having a rank, unpleasant, stale smell or taste, as through decomposition, especially of fats or oils.
