The Vacuum/Steam/Vacuum Process
Prototype process reduces bacteria on solid foods without thermal damage.
Numerous research efforts are underway to eliminate surface bacteria from food. Some attempt to sanitize the surface with aqueous solutions of chemicals such as lactic acid. Some incorporate the antimicrobial agents into the product or packaging. In this manner, they kill the bacteria and leave a residual antimicrobial agent in the product to prevent further recontamination. Some of these agents are commercially available.
There are also thermal processes. One is a commercially available post-pac…
