Novel Technologies — Quiz

Test your understanding of novel technologies with 5 practice questions.

Practice Questions

Question 1

Which novel technology is most effective for extending the shelf life of fresh juices while maintaining their nutritional and sensory qualities, primarily by denaturing proteins and disrupting microbial cell membranes without significant heat generation?

Question 2

A food manufacturer wants to reduce the microbial load on the surface of pre-packaged deli meats without altering their texture or flavor. Which novel technology would be most appropriate, given its ability to generate reactive species at low temperatures?

Question 3

Considering the impact on enzyme activity, which novel technology primarily denatures enzymes through conformational changes induced by extreme pressure, rather than thermal energy?

Question 4

Which of the following describes the primary mechanism by which Pulsed Electric Fields (PEF) inactivates microorganisms in liquid food products?

Question 5

A food scientist is investigating a novel method to enhance the extraction of intracellular compounds from plant cells. Which technology, by inducing reversible permeabilization of cell membranes, would be most effective for this application?
