Vacuum sealing is a form of food preservation used to prevent what in meat?

• A. Keeping meat from freezer burn or spoilage
• B. Maintaining color of meat
• C. Increasing marbling
• D. Reducing fat content

Answer: (A)

Vacuum sealing works by removing air around the meat and sealing it tightly. With less air, oxidation slows and moisture loss is minimized, which slows both freezer burn and spoilage. Freezer burn occurs when exposed surfaces dry out and change texture and color during long storage in the freezer, so reducing air contact helps prevent it. It also slows the growth of microorganisms that need oxygen, extending how long the meat stays safe and fresh. This method isn’t primarily about changing color, marbling, or fat content, which are related to pigments, fat distribution, and composition rather than preservation by air removal.
