The present study evaluated the antioxidant effect of green and black tea (Camellia sinensis L.) extracts in uncured pork sausages. The total polyphenol content in the green tea extract (GTE) was significantly higher (p<0.05) than the black tea extract (BTE). DPPH assay showed significantly higher (p<0.05) antioxidant activity in GTE compared to BTE. However, TBARS values of uncured pork sausages significantly reduced (p<0.05) for all levels of concentrations of BTE (0.05%, 0.10%, 020%, and 0.30%) and GTE (0.05%, 0.10, 0.20%, and 0.30%) during the 5days storage period. The reduction of TBARS values for the BTE 0.05% treated sausage sample was not, however, significantly different (p>0.05) to the BHT 0.10% treated sausage sample on fifth day of the storage period. The sensory evaluation of pork sausages incorporated with a BTE of 0.05% and 0.30%, GTE of 0.05% and the control were not significantly differences (p<0.05) in color, odor, texture, juiciness, taste, or overall acceptability. Practical applicationsIn the present study, we evaluated the antioxidant effect of green and black tea (Camellia sinensisL.) extracts in uncured pork sausages. Adding of black tea extract 0.05%, 0.30%, and green tea extract 0.05% can reduce the TBARS value in uncured pork sausages without altering color, odor, texture, juiciness, or overall acceptability. Therefore, 0.05%, 0.30% black tea extract and 0.05% green tea extracts can be considered as potential antioxidants in uncured pork sausages.
