title: Effect of sodium ascorbate and sodium nitrite on toxin formation of Clostridium botulinum in wieners.
abstract: Toxin production by Clostridium botulinum was inhibited by sodium nitrite levels above 50 mug/g of wiener. Sodium ascorbate at levels of 105 and 655 mug/g of product did not decrease the effectiveness of the sodium nitrite inhibition, nor did sodium ascorbate potentiate it. The results indicate that the use of sodium ascorbate in vacuum-packaged wieners does not appreciably alter the inhibition of C. botulinum toxin formation by sodium nitrite.
