Abstract
Abstract A tubular food casing is treated with an admixture of an albumin and a Maillard reaction product of an amino acid and a reducing sugar to provide a casing that is suitable to impart a smear resistant brown smoke color coating to food products processed therein. Alternatively, a casing is treated first with an albumin and then with a Maillard reaction product.
