Notes:
Cooked meat samples and meat supplemented with 30% hydrated isolated soy protein (ISP), soy protein concentrate (SPC), or textured soy protein (TSP) were inoculated with vegetative cells of Clostridium perfringens and incubated anaerobically at 3 7°C for 24 hr. Of six C. perfringens strains, six sporulated in chicken thigh meat, two in beef, and none in pork sausage. Sporulation was significantly less (P 〈 0.01) in chicken thigh meat or beef supplemented with SPC or TSP than in chicken or beef controls. Sporulation was significantly higher (P 〈 0.01) in beef supplemented with ISP than in beef. Of the three pork sausage-soy protein combinations, sporulation was infrequently detected in pork sausage-ISP samples. The changes in sporulation in chicken or beef by addition of ISP, SPC and TSP were apparently due to a pH effect. With the pH adjusted to 7.5, sporulation of C. perfringens in Duncan-Strong (D-S) sporulation medium with added ISP, SPC, or TSP was similar to or greater than that in D-S medium.
