Can vacuum-packed sauce beef be delivered by SF Express?

Of course. Vacuum-packed sauce beef can be delivered by SF Express, which has a special preservation business and can send vacuum-packed food. The main function of vacuum packaging is to remove oxygen, thus preventing food from spoilage. Its principle is relatively simple, because food mildew and corruption are mainly caused by microbial activities, and most microorganisms (such as mold and yeast) need oxygen to survive. Vacuum packaging is to use this principle to pump oxygen out of packaging bags and food cells, so that tiny objects lose their "living environment".
