What are the types of rancidity

Answers

Answered by Shakespeare0856

There are two basic types or causes of rancidity that contribute to the degradation of stored edible oils: These are:
1- Oxidative rancidity, known as autoxidation, occurs when oxygen is absorbed from the environment.
2- Hydrolytic rancidity, also called hydrolysis or enzymatic oxidation, occurs in the absence of air, but with moisture present.
And the third one,
3- Microbial rancidity, in which micro-organisms such as bacteria, molds and yeast use their enzymes to break down chemical structures in the oil, producing unwanted odours and flavours.

Hope this helps!!!

Ayushpratapsingh2210: but my friend told me that there are 4 types

Shakespeare0856: Yeah..the other type is lypolytic rancidity......but Hydrolytic and Oxidative are the basic types

Ayushpratapsingh2210: can you explain that ?

Shakespeare0856: Lypolytic rancidity is the spoilage of uncooked foods as a result of hydrolysis of fats to free fatty acids on storage by the action of lipase either from bacteria or naturally present in the food.

Shakespeare0856: Is it fine bro???

Ayushpratapsingh2210: thnk u

Ayushpratapsingh2210: yup

Shakespeare0856: You're welcome

Include hydrolytic oxidative and microbial rancidity.

rancidity typically reform to the release of aldehydes and ketones in fats that have unpleasant taste and odors
