  • This experiment was conducted to know the effects of foliar applicated bio-enzyme on the early growth of cucumber and red pepper seedlings. Bio-enzyme was manufactured by the culture and proliferation of Bacillus genus and foliar applicated by the concentration of 0.075, 0.15, 0.3 g.$\ell$-1. Foliar application of bio-enzyme had great influenced to the early growth both cucumber and red pepper seedlings. Optimum concentrations of bio-enzyme applicated for the growth of plant height were determined as of 0.075 g.$\ell$-1 in cucumber but in red pepper seedlings 0.15g.$\ell$-1 was more favored. However, foliar application of 0.15g.$\ell$-1 of bio-enzyme was recommended for both cucumber and red pepper seedlings. Especially, leaf area and total dry weight which are main indices of good seedling were highest in the plot of standard concentrations(0.15g.$\ell$-1)of bio-enzyme.

  • Red pepper calyx cutting devices using a impacting force by a rotational cutter were devised and tested to obtain the fundamental data for development of a calyx removal unit. Fresh red peppers with 80∼87%(w.b.) of initial moisture contents were used as experimental materials. Square and wire type of rotational cutters were used to cut the red pepper calyx and the fresh red peppers were fed into the device both manually and automatically. Three rotational speeds of 250, 500, 700rpm were selected for a square, and 1000, 1500, 1800rpm for a wire type cutter respectively. Four types of red pepper fixing unit were used in manual feeding. The cutting rate of the square type cutter was over 50% regardless the shape and specification of the cutter. For the wire type cutter, the copper wire and nylon chord could not be applied to cut the red pepper calyx because of the low cutting rate. But for the fine wire, the cutting rate was higher and the cutting mechanism was more steady than copper wire and nylon chord. The cutting rate of automatic feeding and wire type cutting unit was about 70% for all levels of the rotational speed. The cutting rate was highly related to the impacting point of red pepper in carrier box. To increase the cutting rate using the rotational cutter, a proper device and mechanism was required to keep the impacting point consistently.

  • 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 Oleoresin Paprika를 첨가하여 기본적으로 매운맛과 고추 고유의 붉은 색상을 부여하였다(simulated seasoning oil, SSO1). 그러나 검붉은 고추 고유의 색상을 얻기 어려워 치자, 고량 등의 천연물로부터 주정추출법을 이용하여 색소를 추출한 후 유화 처리하여 별도로 제조한 검정색 천연색소를 첨가하였다(SSO2). 또한, 통고추가루와 물을 혼합하고 여기에 소량의 인산염을 처리한 후 열수추출 과정을 거쳐 얻어진 고추추출물을 monogly로 유화시켜 SSO2에 혼합함으로써 고유의 매운 맛을 강화하였다(SSO3). 이러한 과정을 거쳐 제조된 향미유의 매운 맛과 색상은 고추씨기름과 유사하였으나 매운 향의 부여는 별도의 과정이 필요하였다. 이에 고추 가루와 고추씨를 동시에 이용하여 직화를 통한 roasting을 하고 여기에 옥수수기름 일부를 가하여 용출을 시도하였다(고추씨기름 원액, SSO4). 여기서 얻어진 고추씨기름 원액(SSO4)을 전체의 5%(w/w) 범위로 SSO3와 혼합하여 최종 RPSO를 제조하였다.

  • 냉동마쇄고추를 첨가한 깍두기의 4$^{\circ}C$ 저장기간중의 이화학적 성분 변화 및 관능적 특성을 알아본 결과는 다음과 같다. pH는 담금 직후 고춧가루를 첨가한 깍두기 마쇄액이 가장 높았고 마쇄 고추를 첨가한 깍두기액이 가장 낮았으며 숙성이 진행될수록 차이가 감소하여 숙성 5주째에는 거의 비슷한 값을 나타냈다. 총산 함량은 전반적으로 마쇄고추 첨가구가 고춧가루 첨가구보다 높게 나타났다. L값은 깍두기 마쇄액이 깍두기액보다 더 높은 값을 나타냈고 마쇄고추를 사용하여 담근 것이 고춧가루를 사용한 것보다 높게 나왔으며 전반적으로 숙성 3주부터는 모든 시료에서 L값의 감소를 보였다. a값은 마쇄고추를 사용한 깍두기액이 전 숙성기간동안 가장 높은 값을 보였고 마쇄액에서는 숙성초기에 고춧가루 첨가구가 마쇄고추 첨가구보다 높게 나왔으나 숙성 2주가 지나면서 반대로 마쇄 고추를 사용한 것이 더 높은 값을 나타냈다. b값은 깍두기 마쇄액에서 숙성 2주까지는 고춧가루 첨가구가 가장 높았고 3주째부터는 마쇄고추 첨가구가 고춧가루 첨가구보다 약간 높은 값을 보이다가 숙성 2주째에는 서로 일치하였고 숙성 3주째부터는 다시 마쇄고추 첨가구의 값이 더 상승하는 경향을 보였다. 유기산 함량 변화에서는 숙성이 진행됨에 따라 citric, quinic, malic acid는 감소 하였고 lactic과 acetic acid는 증가하였다. 또한 citric, lactic 및 malic acid는 마쇄고추 첨가구가, quinic acid는 고춧가루 첨가구가 더 높은 함량을 보였으며 acetic acid는 숙성 후반기인 4주째부터 마쇄고추 첨가구에서 더 증가하는 경향을 보였다. 관능검사에서는 QDA결과 적색도 및 상큼한 맛에서, 소비자 기호도 검사에서는 종합적인 기호도, 외관 및 맛에서 마쇄고추 첨가구가 고춧가루 첨가구보다 유의적으로 높은 값을 보였고 마쇄고추 품종인 칠보, 포청천, 부촌 시료간에는 유의적인 차이를 보이지 않았다. 따라서 깍두기에 마쇄고추를 사용하면 고춧가루를 사용하는 것보다 특히 적색도와 유기산 함량을 증가시켜 깍두기의 기호도에 더 좋은 영향을 줄 수 있음을 알 수 있었다.

  • Meat products have become prevalent in people's diet, and sausages, with the Korean diet getting more westernized in modern times. In particular, emerged as one of the favorite and the most consumed food products in Korea. In order to attain the best recipe to maximize the sausage's sensual taste, we have attempted to experiment and to analyze the differences in characteristic tastes of the sausages with varying increments of crushed red pepper of 0%, 2.5%, 5,%, 7.5%, and 10%. The followings are our findings from our experiment. As the result shows that red pepper, instead of nitrite, added sausage has twice more red chromaticity than those not added, sausage can be colored in red solely with natural materials when sold in the market. pH and moisture decreased as more red pepper was added, it did not show large difference. Texture results showed that the original sausage became harder and its viscosity decreased as more red pepper was added. Cohesion appeared to be similar and red pepper added sausage was munchier and more flexible. In the results of sensory test, 5% of red pepper added sausage showed the highest score but did not have any significant difference. For each items, red pepper added sausage got higher scores and by supplementing it would be seen as a useful additive in developing natural color sausages.

  • This study analyzed the characteristics of single-harvested pepper flakes and investigated the effects of the addition of red and green pepper flakes on the quality of various dressings. Moisture contents of red and green pepper flakes were $14.57{\pm}0.13%\;and\;11.86{\pm}0.12%$, capsaicinoids contents on a dry-weight basis were $207.91{\pm}6.68\;mg/100\;g\;and\;172.32{\pm}5.94\;mg/100\;g$, and total free sugars were $21.63{\pm}1.81%\;and\;12.49{\pm}0.56%$, respectively. ASTA color of red pepper flakes was $150.93{\pm}4.56$. Viable cell numbers of red and green pepper flakes were $3.9X10^4\;CFU/g\;and\;5.2X10^5\;CFU/g$, respectively. The pH values in French dressing and Italian dressing, with added red and green pepper flakes, were slightly increased, but not in American Caesar dressing. Acidity and viscosity weren't statistically different in the 3 kinds of dressings by the addition of red and green pepper flakes. The color difference $({\Delta}E^*_{ab})$ for the storage periods was calculated in each dressing and that of American Caesar dressing with added red pepper flakes was extremely high. Viable cell number in each dressing was maintained at 2 log CFU/g during the storage periods. The sensory characteristics during the storage periods were assessed by members of a trained panel, and showed that the color and pungency of red and green flakes increased the overall preference in the Italian dressing and American Caesar dressing.

  • In this study, the antioxidant activities of red pepper seed kimchi extracts were examined. The extracts were evaluated by various antioxidant assays that included determinations of total phenolic and flavonoid contents, DPPH radical scavenging, superoxide anion radical scavenging, nitric oxide scavenging, superoxide dismutase (SOD) activity, metal chelating activity, and reducing power. All the kimchi extracts showed strong antioxidant activities by the tested methods. The 7% red pepper seed kimchi that was fermented for 6 days possessed the highest activity according to the performed tests. Yet, the highest scavenging activity was exhibited against nitrite, by extracts from kimchi for 0 day of fermentation rather than 6 days. All the activities for the kimchi fermented for 0 day with the addition of 7% red pepper seed increased markedly with an increase in concentration. With the exception of metal chelating and SOD activities, for the antioxidant properties assayed, the red pepper seed kimchi extracts were found to be highly effective.

  • Applicability of near infrared reflectance spectroscopy (NIRS) was examined for quality control of red pepper powder in milling factories. Prediction of chemical composition was performed using modified partial least square (MPLS) techniques. Analysis of total 51 and 21 red pepper powder samples by conventional methods for calibration and validation, respectively, revealed standard error of prediction (SEP) and correlation coefficient ($R^2$) of moisture content, ASTA color value, capsaicinoid content, and total sugar content were 0.55 and 0.90, 8.58 and 0.96, 31.60 and 0.65, and 1.82 and 0.86, respectively; SEP and $R^2$ were low and high, respectively, except for capsaicinoid content. The results indicate, with slight improvement, on-line quality measurement of red pepper powder with NIRS could be applied in red pepper milling factories.
