Shelf Life Testing — Quiz
Test your understanding of shelf life testing with 5 practice questions.
Practice Questions
Question 1
What key assumption underlies the use of the Arrhenius equation for extrapolating shelf life from accelerated tests?
Question 2
A food product exhibits first‐order degradation kinetics with rate constant $k=0.05\ \mathrm{month}^{-1}$. How long will it take for the product’s quality attribute to decline to 80% of its initial value?
Question 3
Which disadvantage is most associated with accelerated shelf life testing?
Question 4
Peroxide value (PV) in an oil increases from 5 meq O$_2$/kg at month 2 to 30 meq O$_2$/kg at month 6. Assuming PV increases linearly with time, at which month will PV reach the threshold of 20 meq O$_2$/kg?
Question 5
Which spoilage marker is best suited for early detection of quality loss in low‐moisture foods like crackers?
