In this study, we exarnined the effects of different concentrations of red pepper seed (0%, 1%, 3%, 5%, and 7%) on pH, total acidity, color, reducing sugar content, total microbes, lactic acid bacteria, and sensory quality, in terms of prolonging the shelf-life of kimchi. The additions of red pepper seed resulted in higher pH leveIs, while total acidity was lower than that of the control. The kimchi with red pepper seed had higher reducing sugar contents than the control. Furthermore, the kimchi with red pepper seed showed higher b-values than the control. During fermentation, the arnounts of lactic acid bacteria and total microbes were higher in the kimchi with red pepper seed than in the control, and the higher ratios resulted in higher quality kimchi. The additions of red pepper seed also resulted in changes of color, flavor, taste, and texture, having a large influence on overall product quality. In conclusion, in terms of preservation and consumption, the 3% and 5% red pepper seed concentrations offered enhanced shelf-life and better quality kimchi products.
Red pepper powder (Capsicum annum L.) is an important seasoning as a kimchi ingredient in korea and most korean consumer tend to eat the korean red pepper powder as the better than other oriental country such as China. Near infrared reflectance spectroscopy (NIRS) was applied for discrimination according to geographical origin (Korea, China) of red pepper powder. The objective of this study is to determine if NIR technique could be used to discriminate between the korean red pepper powder and non-korean red pepper powder according to seed content and maxing ratio in red pepper powder by using the new method. Rapid, precise and nondestructive analysis method for determination of the geographical origin of red pepper powder by near infrared spectroscopy and chemometrics were performed. It has been observed discriminant analysis with PLS is adequate to determinate the geographical origin of red pepper powder. It tend to difficult the discrimination of geographical origin according to increase the seed content of red pepper powder. The accuracy of discrimination in mixed red pepper powder was range from 95.2% to 100%.
반건조 고추의 고추씨 비율을 달리하여 제조한 김치의 품질특성을 조사하기 위하여 고추씨가 20, 40, 60 및 80%의 비율로 첨가된 반건조 고추를 이용하여 김치를 제조한 결과 pH, 산도 및 젖산균의 변화는 숙성 9일째 가장 높았으며 처리구 간의 차이는 보이지 않았다. vitamin C, ASTA, capsaicnoids 함량은 모두 고추씨를 첨가하지 않은 대조구의 함량이 유의적으로 높아 반건조고추의 고추씨 함량이 김치에 큰 영향을 미치는 것으
고추씨기름의 수요는 날로 증가하는데 비하여 국내에서 고추씨의 수급은 어려워지고 있는 실정이다. 이에 따라 고추향미유(red pepper seasoning oil, RPSO)의 개발이 시급한 과제로 떠오르고 있다. 그 동안 몇 군데 업체에서 이와 유사한 향미유가 개발되어 시판되고 있지만 이는 단순하게 매운맛만 부여했을 뿐 향이 전혀 없는 등 많은 문제점을 내포하고 있다. 이에 옥수수기름을 원료유로 하여 여기에 Oleoresin Capsicum과 O
치자로부터 청색 및 황색색소, 고량으로부터 암갈색 색소를 주정을 이용하여 추출ㆍ농축하여 60Brix 농도의 추출물을 회수하였는데, 각각의 수율은 0.68, 1.97, 0.63% (w/w)였다. 이들을 대두유: 물: 유화제: 치자청: 치자황: 고량색소=8: 22: 42: 10: 15: 13 (w/w)의 비율로 혼합하고 균질화하여 유용성 천연 검정색소를 얻었다. 이 색소를 대두유에 용해시킨 결과 대두유의 품온이 30∼4 범위에서 가장 높은 용해도를
