Question

josie bought some frozen meat in a vacuum - sealed package. what is one of the main reasons the manufacturer used this packaging?

a. this packaging helps keep more of the nutrients in the meat.
b. the sealing helps prevent oxidation from occurring.
c. the packaging helps preserve the flavor of the meat.
d. this type of packaging is more biodegradable than other packaging techniques.

Explanation:

Vacuum - sealed packaging removes air from the package. Oxygen in the air can cause oxidation of the meat, leading to spoilage. By preventing air (and thus oxygen) from reaching the meat, oxidation is reduced. While options A and C are also benefits, prevention of oxidation is a key reason. Option D is incorrect as vacuum - sealed packaging is not necessarily more biodegradable.

Answer:

B. The sealing helps prevent oxidation from occurring.
