Back to all questions 5
Question Assertion (A): Pasteurization is a technique of complete sterilization applied usually to milk, meat, fish, etc.
Reason (R): Pasteurization kills a majority of the bacteria usually present in milk.
- A is True and R is False.
- A is False and R is True.
- Both A and R are True.
- Both A and R are False.
A is False and R is True.
Reason — Pasteurization is a method of partial sterilization, typically used for milk. It is not generally used for meat or fish—those typically require different preservation or sterilization methods (like canning or freezing).
Pasteurization kills most of the bacteria, especially pathogenic bacteria, making milk safe for consumption while maintaining its nutritional value.
