Abstract

The aim of this study is to determine the effects of using emulsion manufactured with soybeans (ES) to substitute chicken breast in Vienna sausages. Four types of Vienna sausages (S1: 10% ES and 50% chicken, S2: 20% ES and 40% chicken, S3: 30% ES and 30% chicken, and S4: 40% ES and 20% chicken) for this study were made. And examined pH, color, proximate composition, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), microphotographs, cooking yields, and texture profile analysis (TPA). The uncooked and cooked pH increased significantly with increasing ES content (p<0.05). The crude protein contents of S2, S3, and S4 were significantly higher than that of the control (p<0.05). Furthermore, the SDS-PAGE results showed that α-conglycinin, β-conglycinin, and the acidic subunit of glycinin all increased with increasing ES content. Microphotographs revealed that increasing the ES content decreased the size of fat globules. The cooking yields of samples increased significantly with increasing ES content (p<0.05). The hardness values of ES treated samples were significantly lower than that of the control (p<0.05). Based on these results, 30% substitute of chicken breast with ES can improve the quality and structure of Vienna sausage, without inducing critical defects.
