Abstract

This study investigated the quality characteristics of factory-style ssamjang (FSS) and commercial handmade-style ssamjang (HSS) products. Moisture, crude protein, and crude fat contents were significantly higher in the HSS groups (49.37~62.12%, 9.39~13.46%, and 4.40~8.35%) than the FSS groups (41.94~45.83%, 7.50~9.09%, and 1.81~3.36%). Salt content was higher in the HSS groups (6.33~11.18%) than the FSS groups (6.10~7.57%). Moreover, the average salt content (7.51%) of the HSS groups and the FSS groups was lower than that of commercial ssamjang (8.73%). Hunter's color value was also significantly higher in the FSS groups. However, free sugar, organic acid, and free amino acids contents varied greatly between the FSS groups and the HSS groups, which was likely due to the different manufacturing method, ripening degree of doenjang and the main material used for ssamjang.

본 연구에서는 쌈장 제품의 품질 향상 및 개발에 관한 기초자료를 제시하고자 시판 중인 공장 및 수공업 생산 쌈장 제품 10종에 대한 이화학 성분 분석을 통해 품질 특성을 규명하고자 하였다. 수분 함량은 공장생산 쌈장이 41.94~45.83%, 수공업생산 쌈장이 49.37~62.12%, 조단백 및 조지방 함량은 공장생산 쌈장이 각각 7.50~9.09%, 1.81~3.36%, 수공업생산 쌈장이 9.39~13.46%, 4.40~8.35%로 나타나 수공업생산 쌈장이 수분, 조단백, 조지방 함량 모두 유의적으로 높은 것으로 나타났다. pH와 적정산도는 공장생산 쌈장이 각각 5.29~5.78, 2.18~2.49 0.1 N NaOH mL/10 g, 수공업생산 쌈장이 5.11~5.49, 1.92~3.79 0.1 N NaOH mL/10 g으로 나타났고 아미노태질소 함량은 FSS1과 HSS2를 제외하고는 수공업생산 쌈장(645.48~756.18 mg%)이 공장생산 쌈장(365.08~392.55 mg%)에 비해 월등히 높은 것으로 나타났다. 염도는 공장생산 쌈장이 6.10~7.57%, 수공업생산 쌈장이 6.33~11.88%로 수공업생산 쌈장의 염도가 훨씬 높았고 제품 간 함량 차이도 다소 큰 것으로 나타났다. 또한 전체 평균 염도는 7.51%로 10여 년 전 시판 쌈장의 평균 염도인 8.73%에 비해 함량이 낮아졌음을 확인할 수 있었다. 환원당 함량은 HSS3을 제외하고 공장생산 쌈장(18.77~27.85%)이 수공업생산 쌈장(2.47~21.12%)에 비해 훨씬 높은 것으로 나타났으며 명도, 적색도, 황색도는 전반적으로 공장생산 쌈장의 값이 수공업생산 쌈장보다 유의적으로 높았다. 총 유리당 및 유기산 함량은 각각 HSS3 및 FSS1을 제외하고 공장생산 쌈장(12.51~22.59%, 2,204.31~3,136.78 mg%)이 수공업생산 쌈장(0.58~11.04%, 948.36~1,738.60 mg%)보다 높았고 유리아미노산은 HSS1을 제외하고 공장생산 및 수공업생산 쌈장 모두 glutamic acid 함량이 가장 많았으며, 총 함량은 FSS1 및 HSS1을 제외하고 수공업생산 쌈장(343.50~429.31 mg%)이 공장생산 쌈장(204.08~306.19 mg%)보다 높은 것으로 나타났다. 이상의 결과 공장 및 수공업 생산 쌈장 제품 간 품질 특성에 유의적인 차이가 있었고 동일한 생산방식 내에서도 제품 간 품질특성 차이가 나타났다. 특히 쌈장의 주원료인 된장의 제조방법 및 숙성도에 따라 조단백, 아미노태질소 및 유리아미노산 함량에 차이가 발생하였고 이를 통해 쌈장은 다양한 원료와 재료 배합비 및 방식의 차이에 따라 품질 특성이 다양해 짐을 확인하였다.
