Natural Preservatives

Until recently, there weren't any truly natural primary preservatives. Then Leucidal Naturals came out with radish root ferment, which is based on the microorganisms found in Kimchi. During an epidemic of avian flu, Korean farmers noticed their chickens who were regularly eating a diet containing kimchi were not getting sick. Scientists isolated a compound called radish root ferment and found it to be an effective inhibitor of bacteria at a use rate of 2-4%. it's fully compatible with most products. The only downside is it's a salicylate, which is risky for people with salicylate intolerances or aspirin allergies. Recently they came out with Leucidal SF, which is salicylate free and also highly compatible with most ingredients.
