In post-lethality exposed RTE products, sodium diacetate is an antimicrobial ______ used, whereas drying is an antimicrobial ______ used.

In post-lethality exposed RTE products, sodium diacetate is an antimicrobial ______ used, whereas drying is an antimicrobial ______ used.

• A. agent; process
• B. process; agent
• C. additive; technique
• D. compound; method

Answer: (A)

The key idea is distinguishing between a chemical antimicrobial and a physical antimicrobial method. Sodium diacetate is a chemical compound applied to foods to inhibit microbial growth, so it’s best described as an antimicrobial agent. Drying, on the other hand, is a physical change that reduces moisture and water activity, making the environment less favorable for microbes, which makes it an antimicrobial process. In post-lethality exposed ready-to-eat products, you use both types: a chemical to inhibit growth and a process to limit conditions that allow microbes to thrive. That’s why the completion is agent for the first blank and process for the second.
