Abstract

The objective of this study was to investigate the effects of replacing sucrose with sugar alcohols (sorbitol, glycerol and xylitol) on the quality properties of semi-dried jerky. Total 7 treatments of jerkies were prepared as follows: control with sucrose, and treatments with 2.5 and 5.0% of sucrose replaced by each sugar alcohol, respectively. Drying yield, pH, water activity, moisture content, shear force, myofibrillar fragmentation index (MFI), 2-thiobarbituric acid reactive substance (TBARS) value, sugar content, and sensory evaluation were evaluated. Xylitol slightly decreased the pH when compared to the other sugar alcohols (p>0.05). The water activity of the semi-dried jerky was significantly reduced by treatment with glycerol and xylitol (p<0.05). The moisture content of semi-dried jerky containing various sugar alcohols was significantly higher than that of the control (p<0.05), while replacing sucrose with glycerol yielded the highest moisture content. The shear force of semi-dried jerky containing sugar alcohols was not significantly different for the sorbitol and glycerol treatments, but that replacing sucrose with 5.0% xylitol demonstrated the lowest shear force (p<0.05). The TBARS values of semi-dried jerkies with sugar alcohols were lower than the control (p<0.05). The sugar content of the semi-dried jerkies containing sorbitol and glycerol were lower than the control and xylitol treatment (p<0.05). In comparison with the control, the 5.0% xylitol treatment was found to be significantly different in the sensory evaluation (p<0.05). In conclusion, semi-dried jerky made by replacement with sugar alcohols improved the quality characteristics, while xylitol has applicability in manufacturing meat products.
