Effect of adding different types of flour on the quality of low fat beef sausage
Keywords:sausage, beef, flour, acceptability
The experiment was conducted to find out the effect of different types of flour on the sensory, physicochemical, biochemical and microbiological properties of beef sausages. For this purpose, sausages were prepared into four different groups. They were treated control; beef sausage without flour, beef with 10% rice flour, beef with 10% wheat flour and beef with 10% corn flour. All parameters were analyzed at 0, 15th and 30th days of storage time. The proximate compositions of different sausage batters are analyzed and highly significant differences were found in dry matter and crude protein (%) content and significant differences were found in cooking loss (%), pH (%) and EE (%) content. While analyzing the different types of sausages, highly significant differences were found in pH, DM (%), CP (%) and EE (%) content and significant differences in Ash (%) content. Crude protein (%) and DM (%) increased, while Ash (%) and EE (%) decreased with increase of storage time. Significantly higher DM (%) and CP (%) were found in beef sausage without any flour, no significant differences were found among the flour groups in DM (%) and CP (%) content. The storage period had significant effect on different biochemical (FFA, POV and TBARS value) and microbial (TVC, TCC and TYMC) test. In all cases the values were increased with increase of storage time. The surface color (CIE L*, a*, b*) of sausages of different treatments at different storage period were measured. No significant differences in L* value were found among beef sausages and storage time. On the other hand, different types of sausages had a significant effect on a* and b* values. Significantly higher a* value was found in beef sausage with 10% corn flour and b* value in beef sausage without any flour (Control). Storage period had no effect on b* values, but effect on a* values. Significantly lower a* value was found at 0 day of storage time. In sensory analysis, highly significant differences were found in flavor, off-flavor, juiciness, tenderness and overall acceptability among four types of sausages but no significant found in color. All the parameters were significantly lower in control sausage except off-flavour, which was significantly higher in control sausage. No significant differences were found in sensory parameters among the sausages manufactured from different types of flour. From this experiment, it might be concluded that addition of different types of flour increases the overall acceptability of beef sausage.
