Abstract

The differences between organic and conventional soybean were studied based on their physicochemical properties by steaming treatment. There was no difference between the two kinds of soybean regarding crude protein, crude fat and crude ash contents. Reduction in sugar content was higher in raw organic soybean than raw conventional soybean. However, there was no difference between the two soybeans after steaming. Amino nitrogen content was higher in organic than conventional soybean. Further, there was no difference between the two soybeans after steaming. Regarding pH, acidity and salinity, there was no differences between the two soybean after steaming. Organic soybean was more bright than conventional soybean after steaming. The yeafercontent and number of bacteria in raw soybean were not different between the two soybean types. The number of fungi was higher in organic than conventional soybean. Upon steaming, the yeast number was different between two kinds of soybean. Further, the number of bacteria was higher in organic than conventional soybean. The number of fungi was not different between the two soybeans.

유기 재배 및 일반 재배로 생산된 콩의 조리 전후의 이화학적 특성을 분석한 결과는 다음과 같다. 생콩과 가열 조리한 후의 일반콩과 유기콩 간에는 조단백, 조지방 및 조회분 등과 같은 일반 성분에는 유의적인 차이가 나타나지 않았다. 생콩에서 환원당은 유기콩이 일반콩보다 유의적으로 높았다. 조리 후에는 일반콩과 유기콩간에 차이가 없었다. 아미노태질소는 일반생콩보다, 유기생콩이 유의적으로 높았다. 조리 후에는 일반콩과 유기콩의 두 콩간에 유의적인 차이는 나타나지 않았다. pH는 조리 전 일반콩이 유기콩보다 높았고, 조리 후에는 일반콩과 유기콩 간에 유의적인 차이는 없었다. 적정 산도 분석 결과 생콩 8.00에서 조리 후에는1.00으로 산도가 급격히 저하하는 것으로 나타났으나 일반콩과 유기콩 간에 차이는 전혀 없었다. 염도도 일반콩과 유기콩 간에 차이가 나타나지 않았다. 조리 전후 일반콩과 유기콩의 색도 측정결과, 조리 전 일반콩 66.02, 유기콩 62.97로 나타났고, 조리 후에는 일반콩 55.66, 유기콩 59.40로 나타나 조리 후 유기콩이 약간 밝은 경향이었다. b값은 조리 전 일반콩과 유기콩간에 차이가 없었고, 조리 후에는 일반콩에 비해 유기콩이 약간 밝았지만 유의적인 차이는 나타나지 않았다. a 값은 조리전 일반콩보다 유기콩이 높게 나타났다. 일반콩 및 유기콩의 미생물의 변화는 생시료 시 곰팡이와 효모는 차이가 없었으나, 세균은 유기콩이 높았다. 조리 후에는 효모와 곰팡이는 차이가 없었으나 세균은 유기콩이 높게 나타났으므로, 향후 이 부분에 대한 유용성과 유해세균에 대한 검토가 더 필요할 것으로 사료된다.
