Practice Questions

Question 1

In a food science experiment investigating the effect of different cooking temperatures on the degradation of a specific vitamin, which of the following statistical models would be most appropriate to describe the relationship between temperature and vitamin retention, assuming a non-linear relationship?

Question 2

A food scientist is developing a new functional beverage and wants to assess its impact on specific biomarkers in human subjects. To minimize the influence of individual physiological variations among participants, which experimental design approach would be most effective?

Question 3

When validating a new analytical method for detecting a food allergen, researchers compare its results against a well-established reference method. To quantify the agreement between the two methods, particularly in terms of correctly identifying positive and negative samples, which statistical measure is most appropriate?

Question 4

A food manufacturer is investigating the relationship between the concentration of a novel antimicrobial agent and its effectiveness in inhibiting bacterial growth in a ready-to-eat meal. They measure bacterial counts (log CFU/g) at various concentrations of the antimicrobial agent. Which statistical technique is most suitable for developing a predictive model for bacterial inhibition based on antimicrobial concentration?

Question 5

In a study assessing the impact of different packaging materials on the shelf life of a fortified milk product, researchers measure the degradation of a specific vitamin over 12 weeks. They collect data from the same milk samples stored in different packaging types at weekly intervals. Which statistical method is most appropriate to analyze the change in vitamin concentration over time for each packaging type, considering the repeated measurements on the same samples?
