Question

what is rancidity? How can we reduce the problem of rancidity.​

Answer 1

Lipid oxidation is one of the major reasons that foods deteriorate and is caused by the reaction of fats and oils with molecular oxygen leading to off-flavours that are generally called rancidity. ... The other cause of rancidity is by a combination of enzymes and moisture.

Adding antioxidants (substances which prevent oxidation) to food.
Storing food in airtight containers to slow the process of rancidification.
Refrigerating food also helps to slow down rancidification.
Replacing oxygen in the containers with another g

Answer 2

Answer and Explanation:

$\diamond$ Chemical reactions are processes in which one or more substances (reactants) react or combine together to form one or more substances (products)

$\diamond$ A general chemical reaction can be given as :

$\huge \text{\boxed{\boxed{\mathcal{{REACTANTS \rightarrow PRODUCTS}}}}}$

$\diamond$ Rancidity is a chemical reaction in which there is complete or incomplete oxidation or the hydrolysis of fats and oils when it is exposed to air, light, moisture or bacterial action

$\diamond$ This reaction causes unpleasant odour and taste

$\diamond$ Rancidity can be reduce by many methods like :

1. Adding anti-oxidants which can reduce or stop the rate of oxidation
2. Vacuum packing the food
3. Replacing air with nitrogen which will result in reduction of the rate of oxidation with air
4. Refrigerating the food
5. Packing the food in air-tight containers
