Effect on rancidity of chinese sausage by adding the extracted anthocyanin from black non-glutinous rice bran

Abstract

The aim of this research was to studied on the optimization of adding the extracted anthocyanin from black non-glutinous rice bran for prolonging shelf-life of Chinese sausage. The study was done by adding the anthocyanin extracts of 2 and 3 % with the combination of sodium nitrite 0 and 1 % during the processing of Chinese sausage. The sensory attributes evaluated using a nine-point hedonic scale and by using ranking test. The physicochemical analysis of storage study was conducted for 4 weeks. All analysis were carried out in every weeks. The results showed that Chinese sausage with added anthocyanin extracts of 3 % with the combination of sodium chloride 2 % gave the lowest value of moisture content with significantly difference (p<0.05). Chinese sausage with added sodium nitrite 1 % with the combination of the anthocyanin extracts of 3 % gave the highest score of overall acceptability. The product can retard oxidation with the value of TBA lower than the control sample with significantly difference (p<0.05)
