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)

Effect of tomato powder as sodium nitrite replacer on qualities of Frankfurter was studied. The ratio of tomato powder: sodium nitrite were 0: 2 0.5: 1.5 1: 1 and 1.5: 0.5 respectively. Physicochemical microbiological and sensory properties during storage in vacuum seal at 4 ?C for 21 days were studied. The results were found that the optimum ratio of tomato powder: sodium nitrite was 1: 1 that produced the highest in a* and b* which was higher lycopene content than control. Furthermore it had the highest scores in appearance color and flavor. In addition the formula with the ratio of 1.5 : 0.5 had the highest total acidity and lycopene content but the lowest in hardness gumminess flavor taste texture and overall liking. The ratio of 1: 1 was increased in total acidity TBA and L* after longer storage. Whereas a* flavor taste and overall liking were decreased upon storage time. The sausage that storage before 14 days was accepted in physical chemical microbiological and sensory properties consumer acceptance.
