Effect of the Addition of Tomato Powder on the Color and Storage Quality of Red Sausage

摘要

This study includes the investigation of the chemical properties such as pH value and a*-value, sensorial evaluations, residual nitrite and the oxidation level of Chinese-style sausage—red sausage, which have been produced by both reducing the nitrite level( 50mg/kg, 100mg/kg and 150mg/kg) and adding tomato powder( 0%, 2% and 4%). According to the results, 100mg/kg of nitrite together with 2% tomato powder is better. Then the sausages produced with 100mg/kg nitrite and 2% tomato powder, along with sausage which produced with only 150mg/kg of nitrite are stored at 4 °C for 45 days. It was observed that addition of 2% of tomato powder increased degradation of nitrite and decreased the level of oxidation. This study provides a potential solution for nitrite substitute in meat products.
