Question

Which of the following is NOT the advantage of lyophilization?

(a) Dissolution of product

(b) Processed in aseptic conditions

(c) Handling and processing time increases

(d) Do not use heat

This question was addressed to me during an interview for a job.

My question comes from Preservation of Industrial Microorganisms topic in portion The Isolation, Preservation and Improvement of Industrial Microorganisms of Fermentation Technology

Answer 1

Correct answer is (c) Handling and processing time increases

To explain I would say: The processing and the handling time in lyophilization are more as there are many incubation periods, thus a time-consuming process. Handling and processing time is a major disadvantage of lyophilization.
