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.
Antioxidants are commonly added to fat and oil containing foods to prevent the development of rancidity. They help to inhibit the oxidation process that leads to the off-flavors and odors associated with rancidity. Common antioxidants include butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), and tocopherols.
Examples of microbial rancidity include the spoilage of food products like bread, dairy, and meat by microorganisms such as bacteria and fungi, leading to off flavors, odors, and texture changes. Additionally, microbial rancidity can occur in fats and oils due to the action of lipolytic microorganisms, resulting in the production of unpleasant and rancid-smelling compounds.
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.
The chemical equation for rancidity involves the reaction of fats or oils with oxygen to form peroxides and aldehydes, resulting in off-flavors and odors. This process is known as lipid oxidation and can be represented by various reactions depending on the specific fatty acid composition of the lipid undergoing rancidity.

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.
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.
chemical reaction takes place in 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 means having a rank, unpleasant, stale smell or taste, as through decomposition, especially of fats or oils.
