Semi-dried restructured sausages are restructured meat products with a high nutritional and economic value. However, excessively long drying times can have negative effects on the energy consumption, texture, and sensory properties of semi-dried restructured sausages. The objective of this study was to investigate the effects of different water contents on the drying and physicochemical characteristics of semi-dried restructured sausages. Sausages were prepared with different initial moisture contents (0%-50%) and drying time (0-580 min). The drying characteristics, including the drying rate, effective moisture diffusivity, and water activity of sausage were significantly improved as the initial moisture content was increased. When the initial moisture content of the sausage was 50%, physicochemical properties, such as color, porosity, shear force, and volatile basic nitrogen, were improved the most along with the decreased drying time. Scanning electron microscopy data showed greater porosity and pore size in sausages with the increase of initial moisture content. Collectively, our data suggest that an increase in the initial moisture content of semi-dried restructured sausages improves their drying characteristics and physicochemical properties.

Effects of the addition of kimchi powder on the physico-chemical and sensory properties of semi-dried sausages were investigated at the following kimchi powder concentrations: control (0%), T1 (1%), T2 (2%), and T3 (3%). pH of the semi-dried sausages containing kimchi powder decreased with the addition of kimchi (p<0.05). Also, the addition of kimchi powder to the sausages significantly decreased the CIE $L^*$ and increased the CIE $a^*$ and CIE $b^*$ values (p<0.05). The T3 treatment resulted a higher mositure lose than other treatments. TBARS values of the T2 and T3 groups were significantly lower (p<0.05) than that of the control, while T3 had the highest VBN value among treatments at the end of the storage period. Addition of kimchi powder to semi-dried sausages improved the overall sensory properties of the sausages, and increased the softness and tenderness. These results suggest that addition of 2% kimchi powder to semi-dried sausage is helpful to improve the quality of sausages.

This study was performed for development of new analytical method of monascus pigments in foods. In this method, analysis of monascus pigment in foods has been carried out by detection of monascin and ankaflavin of the main color component of monascus pigment as indicator compounds. Monascin and ankaflavin were isolated and identified by TLC, HPLC, Prep. HPLC, $^{1}H-NMR$ and Mass spectrophotometer. The analysis of monascin and ankaflavin in foods such as massal, sausage, mixed press ham, mixed fish sausage, semi-dried sausage and syrup was performed by using reverse phase high performance liquid chromatograph with Capcell Pak C18 column at wave length 390 nm. The quantitative results of monascin were as follows : $0.01{\sim}3.31\;{\mu}g/g$ item in massal, $0.05{\sim}0.10\;{\mu}g/g$ in mixed fish sausage, and $0.34{\sim}0.35\;{\mu}g/g$ in semi-dried sausage. But the quantitative results of ankaflavin were as follows: $0.02{\sim}0.89\;{\mu}g/g$ in massal, ankaflavin were not founded in other samples.
