Food Science and Technology QUESTION #5930

Question 1

The 'Log Reduction' concept in pasteurization states that HTST (\(72^{\circ}\text{C}/15\;\text{s}\)) achieves a minimum log reduction of \(Coxiella\;burnetii\) of:

5-log \((10^5\text{-fold})\)✔️
6-log
3-log
8-log

Correct Answer Explanation

HTST pasteurization (\(72^{\circ}\text{C}/15\;\text{s}\)) is designed to achieve a minimum \(5\)-log (\(100{,}000\)-fold) reduction of \(Coxiella\;burnetii\), the most heat-resistant non-spore-forming pathogen in milk and causative agent of Q fever.
