$small{L}$-아르기닌의 알칼리성과 보습성을 식품에 활용하는 연구의 일환으로 폴리인산염 대신에 $small{L}$-아르기닌을 0.25, 0.5, 1.0% (w/w) 첨가하여 소시지를 제조하고, 각각의 pH, 보수력, 유화 안정성 및 조직감을 조사하였다. 소시지의 pH는 $small{L}$-아르기닌의 첨가량에 비례하여 증가하였으며, 수분함량은 $small{L}$-아르기닌을 0.25% 이상, 유화 안정성은 0.5% 이상, 경도와 전단력은 1.0%를 첨가한 결과가 폴리인산나트륨을 0.5% 첨가한 소시지의 특성과 유사하였다. 인산염 0.5%와 $small{L}$-아르기닌 0.5% 첨가 소시지에 대하여 관능 평가를 실시하였다. 조직감은 인산염을 사용한 시료가 $small{L}$-아르기닌을 첨가한 시료보다, 맛과 전체적인 기호도에서도 $small{L}$-아르기닌을 첨가한 소시지가 다소 우수한 것으로 평가되었다. 이상의 결과로부터 소시지 제조시 $small{L}$-아르기닌은 인산염 대체 소재로 활용될 수 있으며 첨가량은 0.5%가 적절함을 확인할 수 있었다.
$small{L}$-Arginine was applied to processed pork sausages and evaluated as a substitute for commonly used inorganic polyphosphate. Processed pork sausage was prepared with an addition of 0.25, 0.5, and 1.0% (w/w) $small{L}$-arginine. Quality characteristics of the processed pork sausages were than evaluated in terms of pH, moisture content, emulsion stability and textural properties. The pH of sausage increased with increasing $small{L}$-arginine concentration. Moisture content of 0.25% $small{L}$-arginine sausage, emulsion stability of 0.5% $small{L}$-arginine sausage, and textural properties of 1.0% $small{L}$-arginine sausage were similar to those of 0.5% polyphosphate sausage, respectively. In terms of sensory evaluation, taste and overall acceptability of 0.5% $small{L}$-arginine sausage were slightly higher than those of 0.5% polyphosphate sausage and textural properties were reversed. According to sensory score and quality characteristics, $small{L}$-arginine had a potential as a substitute for inorganic polyphosphate and the optimum concentration of $small{L}$-arginine was around 0.5%.
