Which statement is incorrect for pasteurization?
Correct answer: D. It can be used to preserve vegetables and meat.
- A. It is used to preserve yogurt and milk
- B. It was developed by Louis Pasteur.
- C. It involves heating the substance at high temperature for just few sec.
- D. It can be used to preserve vegetables and meat.
Explanation
Pasteurization is mainly used for liquids such as milk and fruit juice, using controlled heating to destroy harmful microorganisms without completely sterilising the product. Vegetables and meat are generally preserved by methods such as refrigeration, freezing, drying, canning or irradiation, so option d is the incorrect statement. Option c can describe high-temperature short-time pasteurization, although not every pasteurization method uses only a few seconds.
