EFFECTS OF SYNTHETIC MEAT COMPONENTS ON GROWTH OF CLOSTRIDIUM PERFRINGENS1,2

The 16 ingredients used to fabricate synthetic soybeef (ground beef analog) were evaluated for stimulatory effects on growth of Clostridium perfringens. Four ingredients–beef-like flavor, corn flour, cocoa, and vegetable oil–stimulated growth of C. perfringens. The remaining 12 ingredients showed no significant effect. The most stimulatory ingredients, beef-like flavor and corn flour, were optimally stimulatory over a wide range of concentrations, Thus, control of growth of C. perfringens may not be obtained by manipulation of the concentration of these ingredients in the absence of other precautions.
