Abstract

Process development and standardization are necessary in maintaining high hygienicquality of side dishes. Seasoned perilla leaves are a typical side dish needing process development. In this study the optimum condition for preparing seasoned perilla leaves was investigated experimentally. The best sensory quality was established by response surface methodology. The rinsing and washing method of preparing fresh perilla leaves was optimized to decontaminate the raw material and preserve the product in chilled storage. Washing and rising with 3% salt water reduced the aerobic bacterial count of perilla leaves to 0.55 (log CFU/g), while rinsing reduced the load from 8.08 to 4.27 (log CFU/g). The effect of rinsing method was maintained during subsequent storage of the prepared seasoned leaves at $10^{\circ}C$. There was no significant quality change in the product during chilled storage at $10^{\circ}C$. Soaking in 3% salt water for 1 min, followed by rinsing with tap water, contributed positively to the microbial quality, and is proposed as the optimal preparation method.

한국의 고유 식품인 깻잎은 위생적, 고품질 및 규격화된 가공방법의 개발이 요구된다. 본 연구에서는 깻잎 절임의 관능적, 위생상 안전성이 향상된 최적조리 조건을 확립하고자 하였다. 그 결과 반응표면분석에서는 저장기간에 따른 성분 조성의 최적값에는 차이가 있으나 저장식품인 경우를 고려할 때 간장 $24{\sim}27g$, 물엿 24 g이 전반적으로 적합한 것으로 나타났다. 깻잎의생균수는 세척전 8.08 cfu/g에서 세척 후 4.27 cfu/g 으로 약 50% 수준으로 감소하였다. 또한 3% 염수에 침지 후 세척한 깻잎은 0.55 cfu/g으로 미생물이 대부분 제거되었다. 이는 가열 조리하는 방법의 밑반찬과는 달리 비열처리되는 반찬이므로 저장성에 효과가 있을 것으로 판단된다. 깻잎 절임의 저장 중 품질 변화에 있어서 배합조건에 대한 큰 차이는 볼 수 없었으나, 전처리 및 세척 방법에 따른 저장성의 차이가 나타났으며, 3% 염수에 1분간 침지 후 수돗물에 헹궈서 이용하는 것이 미생물 생육을 억제하고 저장성에도 가장 효과가 우수하였다.
