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.

우리나라에서 허용된 천연색소인 홍국색소는 "천연식품[식육류, 어패류(경육포함), 과실류, 채소류, 해조류, 두류 등 및 그 단순가공품(탈피, 절단 등)], 다류, 고춧가루 및 실고추, 김치류, 고추장 및 식초"에 사용금지토록 사용기준이 규정되어 있으나, 현재 식품중 홍국색소의 분석방법이 아직 확립되어 있지 않은 실정이므로 식품중 홍국색소의 최적분석방법을 확립하고자 하였으며, 확립된 분석법을 적용하여 국내유통중인 식품중 홍국색소의 함유량을 조사하였다. 따라서, 식품중의 홍국색소는 TLC, HPLC, Prep. HPLC, $H^1-NMR$ 및 MS로 홍국색소성분 중 monascin과 ankaflavin을 분리 확인하였으며, 이 두 성분을 표준물질로 하여 다음과 같은 정량분석법을 확립하였다. 역상계 칼럼인 Capcell pak $C_{18}$ UG120을 이용하여 HPLC 분석을 하였으며, 이 때 이동상 및 파장조건은 각각 메틸알콜 : 물 : 초산(75 : 25 : 0.5) 및 390 nm이었다. Monascin, ankaflavin의 회수율은 혼합어육소시지, 시럽, 맛살, 반건조소시지, 혼합프레스햄, 소시지 순으로 나타났으며, 혼합어육소시지에서는 평균 94.1%, 92.9%로 가장 높았고 맛살에서는 평균 85.1%, 85.8%의 회수율을 나타냈다. Monascin은 소시지, 반건조소시지, 혼합프레스햄, 시럽 등에서 평균 $71.5{\sim}88.6%$로 양호하였으나, ankaflavin은 평균 $40.0{\sim}59.4%$로 비교적 낮은 회수율을 나타냈다. 조사대상식품인 국내유통 가공식품중 맛살, 소시지, 혼합어육소시지, 반건조소시지, 혼합프레스햄 및 시럽 등 총 6종에 대하여 monascin과 ankaflavin의 함량을 확립된 분석법으로 정량분석한 결과는 다음과 같았다. Monascin의 경우 맛살에서 $0.01{\sim}3.31\;g/g$ 혼합어육소시지에서 $0.05{\sim}0.10\;g/g$, 반건조소시지에서 $0.34{\sim}0.35\;g/g$이 각각 검출되었고, 나머지 품목에서는 모두 불검출이었다. 한편, ankaflavin의 경우 맛살에서만 $0.02{\sim}0.89\;g/g$이 검출되었으며, 나머지 품목에서는 모두 불검출이었다.
