Question
I am looking to extend the shelf life of a tuna pate that my company produces.  I learned about a preservative, Natamycin, from a cream cheese container and was wondering if you know about this particular preservative or could suggest any alternatives.

Thank you for your time and assistance,

Steve Price  

Answer
Mr. Price:
Natamycin may reduce spoilage due to molds in your product.  However, I would use this with caution, since pate products have been assigned by USDA as high risk for Listeria monocytogenes food poisoning.  Increasing your shelf life would likely increase the risk of disease transmission.  I suggest you get professional help either from your university extension servive or a consulting company.
