Comparison of ‘Natural Nitrite’ vs Sodium Nitrite for Inhibition of Spores of Clostridium sporogenes in Low- and High-Fat Hotdogs
Peter Muriana, food microbiologist at FAPC, focused research on the approval of the category, ‘natural meats’, whereby no artificial ingredients are allowed brought a dilemma in the use of sodium nitrite (synthetic), a regulated food preservative used for curing in processed meats. USDA-FSIS approved of the concept of fermentation conversion of vegetable nitrate to ‘natural nitrite’ and further declared that when used, product ingredient labels can state “no added preservatives” or “no added nitrite” (except that which is found naturally in fermented vegetable extracts); however, such products cannot be considered ‘cured.’
The goal of the project was to a) compare the control of Clostridium spores using sodium nitrite vs celery nitrite in low-and high-fat hotdogs, b) to use spores of Cl. sporogenes that is a non-pathogenic surrogate for pathogenic Cl. botulinum/perfringens, and c) examine whether bacteriocins (natural bacteria byproducts) can have inhibitory activity to prevent germination of Clostridium spores or growth of vegetative cells to complement nitrite activity.
