Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R Assertion A:- Butylated hydroxyl anisole when added to butter increases its shelf life. Reason R:- Butylated hydroxyl anisole is more reactive towards oxygen than food. In the light of the above statements, choose the most appropriate answer from the options given below:-

Options

  1. ABoth A and R are correct and R is the correct explanation of A.
  2. BA is correct but R is not correct.
  3. CA is not correct but R is correct.
  4. DBoth A and R are correct but R is NOT the correct explanation of A.

Correct answer

A. Both A and R are correct and R is the correct explanation of A.

Step-by-step solution

Antioxidants are important and necessary food additives. These help in food preservation by retarding the action of oxygen on food. They act through several chemical mechanisms. Butylated hydroxy anisole (BHA) is one of the familiar antioxidant. The addition of BHA to butter increases its shelf life from months to years as it is more reactive towards oxygen than food. Hence, both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
