The Sulfide Black in Pork Lunchern Meat Can and the Selection of the Material for Container

This article analyzed the principle of sulfide black formed inside of can of pork lunchern meat, and described how to prevent the metal reaction between the product and inside wall of can. The formed conditions of sulfide stain and iron sulfide in the canned samples were evaluated after filling sterilizing and incubating for 2～180 days by the way of orthoganal test of three factors and three levels to test the chromium content on tinplate surface, tin coating weight and lacquer. And through the analysis of orthoganal test data, the selection of material for container was discussed in this article.
