The inhibition of Clostridium botulinum growth and toxin production by essential oils of spices
… 67B. The most effective oil, in combination with sodium nitrite at different levels was further tested against the growth and toxin production of C. botulinum (mixed types) in a meat model system. Among all the spice oils, origanum and pimenta were the most effective in inhibiting six strains of …

Sodium hypophosphite inhibition of Clostridium botulinum in pasteurized comminuted pork
Sodium hypophosphite was evaluated for inhibition of growth and toxin production of Clostridium botulinum in a model meat system. Fresh comminuted pork was formulated to contain 0, 1000, or 3000 ppm sodium hypophosphite, with or without 50 ppm sodium nitrite, and 156 ppm sodium nitrite. The test …

Synthesis of symmetric and asymmetric water-soluble porphyrin derivatives
… of metal free-dodecasubstituted porphyrin with sodium nitrite and trifluoroacetic acid at room temperature in the presence of oxygen affords ring-opened benzoylbiliverdin in 77-80% yields. These compounds are metallated with several diamagnetic metal ions and their structures confirmed by NMR …

Functional comparison of soy protein isolate and sodium caseinate in stabilized fat mixtures
… of the ten minute chopping cycle, a solution of sodium nitrite and water was added to deter fat rancidity. Essentially no fat or water cookout resulted when a stability test of the final mixture was performed. A comparison of the physical characteristics of both the caseinate and soy isolate …

The Impact of Nitrite on Aerobic Growth of Paracoccus denitrificans PD1222
The effect of nitrite stress induced in Paracoccus denitrificans PD1222 was examined using additions of sodium nitrite to an aerobic bacterial culture. Nitrite generates a strong stress response in P. denitrificans, causing growth inhibition. This is dependent on both the concentration of nitrite …
