  • This study investigated the heat level rating of several varieties of Korean red peppers. The chemical constitution of Korean red pepper samples were as follows: 0.54~290.15 mg% capsaicinoids, 79.22~139.09 ASTA value, and 16.76~29.92% free sugar content. The heat level of the Korean red pepper samples was evaluated by trained panelists and the correlation coefficient and F value (0.001%) of the panelist’s results were determined to be significant. In the principle component analysis (PCA), PC1 (capsaicinoids) and PC2 (free sugar) were shown to represent 31.98% and 25.77% of the total variance, respectively. The results of panelists trained for red pepper heat rating were evaluated using analysis of variance and correlation analysis. The trained panelists showed a high F value (p=0.05) and high correlation coefficient. A high correlation efficient of 0.84~0.93 for the test samples with a 40 Scoville heat unit (32,000 SHU red pepper powder) was reported in the sensory evaluation of the Korean red pepper heat level by a trained panel. However, the panel showed a low correlation efficiency of 0.70 $R^2$ when the 60 SHU test samples were included in the analysis.

  • From the point of breeding view for our future, 20 Korean varieties of red pepper for the contents of capsaicinoids, free amino acids, free fatty acids and organic acids with powder product and eating qualities were chosen, and the sensory properties of their water and ethanol extract were compared in order to investigate the influence of the composition of test components on sensory acceptability of Korean red pepper. The composition of taste components in red pepper powder varied wildly depending on the varieties; total capsaicinoids content variety from 0.029 to $0.913\%$, free sugar 8.45 to $20.2\%$, and organic acid 4.58 to $19.54\%$. Capsaicinoid contents especially dihydrocapsaicin content, were highly correlated with pungent taste of the methanol extract of red pepper power, but did not show significant relationship to the overall sensory acceptability. However, the components analyzed here and eating and processing qualities include high variations and future breeding sources.

  • Antinociceptive and desensitizing effects of systemically administered capsaicinoids (capsaicin and KR25018) were investigated in guinea pig. Nociceptive sensitivity to chemical stimulus was examined to test sensory function, and the content of substance P-like immunorractivity (SP-LI) in bronchi was determined as a peripheral marker of capsaicin-sensitive primary afferent neurons. Guinea pigs were pretreated s.c. with several doses of capsaicin (1,2.5,5, 10 mg/kg) or KR25018 (1, 2.5, 5, 10 mg/kg) one week prior to the experiments. Frequency of eye wiping was significantly decreased by capsaicin and KR25018 in a pretreatment dosedependent manner. In capsaicin- or KR25018-pretreated guinea pigs, there was a significant loss of SP-LI in bronchial tissue extracts. In summary, a newly synthesized capsaicin analogue H725018 exhibited antinociceptive effect against chemical stimulus in guinea pig, with comparable potency to capsaicin. This desensitizing activity of capsaicin or KR25018 might be related to the loss of SP-LI in peripheral afferent nerves.

  • Capsicum annuum belongs to the Solanaceae family, crops of which are extensively cultivated worldwide. It is a food source containing various nutrients and vitamins and also serves as a medicine for treating ailments. The burning feeling experienced while consuming Capsicum fruits is due to the presence of capsaicinoids, particularly capsaicin and dihydrocapsaicin. This study aimed to assess the content of these two compounds in 34 varieties of capsicum and paprika. High-performance liquid chromatography with a gradient elution system and a reverse-phase YMC Pack-Pro column with UV detection at 280 nm was employed. The results revealed that, among the 34 samples, only six samples (samples 1, 15, 20, 29, 32, and 34) contained capsaicin and dihydrocapsaicin, and their highest contents were found in sample 1 - variety name: Sungil-c (capsaicin: 3.42 mg/g extract, dihydrocapsaicin: 1.20 mg/g extract). These findings suggest that the content of these two compounds is attributed to the variety and is influenced by geographical location and environmental factors. Additionally, this study provides a basis for establishing a C. annuum variety with high capsaicin and dihydrocapsaicin contents.

  • 본 연구에서는 건조방법에 따른 고춧가루의 품질 변화를 비교하기 위하여 한 가지 품종의 고추를 PE House 건조, 열풍건조, 원적외선 방법을 이용하여 건조한 다음, 건조조건별로 고춧가루의 수분함량 변화, pH, ASTA value 및 capsaicinoids와 vitamin C의 함량을 조사하였다. 건조 후 고춧가루의 수분함량은 12.05~14.01% 함유한 것으로 나타났으며, pH는 건조 전 생고추인 4.93보다 다소 높은 5.00~5.54를 나타내었다. 고춧가루의 매운맛을 나타내는 총 capsaicinoids의 capsaicinoids의 함량은 PE House 건조에서 224.40 mg/100 g으로 가장 높게 나타났으며, 열풍 $70^{\circ}C$ 건조에서 191.87 mg/100g으로 가장 낮게 나타났다. 하지만 건조방법에 따른 capsaicinoids 함량이 유의적 차이를 보이지 않았기 때문에, 매운맛 함량의 변화는 큰 차이를 나타내지 않았다. 고춧가루의 대표적 항산화제인 vitamin C 함량은 다른 건조방법 및 조건에 비해 PE House, 열풍 $60^{\circ}C$과 원적외선 $60^{\circ}C$에서 596.60~648.31 mg/100 g으로 높은 수준의 함량을 나타내었다. 소비자가 고춧가루를 선택하는데 중요한 요소로 작용하는 ASTA value는 126.68~156.77로 건조방법 및 조건에 따른 유의적 차이를 나타내지 않았다. 따라서 고추의 건조방법 및 조건을 낮은 온도 조건에서의 열풍, 원적외선 건조방법으로 결정한다면 고춧가루의 vitamin C의 손실을 최소화하고 PE House 건조에 비해 신속하며 오염을 예방하는 고품질의 고춧가루 제품을 생산할 수 있을 것으로 생각된다.

  • Capsaicin [N-(4-hydroxy-3-methoxybenzyl)-trans-8-methyl -6-nonenamide], a pungent principle of red pepper. is known to induce analgesia. Though it has shown remarkable pharmacological activity, the toxicity and side effects inhibited its wider application. The interest has been renewed by the emergence of its agonists, resineferatoxin and ruthenium red. Recently, few successful capsaicinoids including 01vanil (NE-19550), NE-28345, and NE-21610 were reported.

  • Chili pepper (Capsicum annuum L.) is an economically important horticultural crop in Korea; however, various diseases, including Phytophthora root rot, anthracnose, powdery mildew, Cucumber mosaic virus (CMV), Pepper mild mottle virus (PMMoV), and Pepper mottle virus (PepMoV), severely affect their productivity and quality. Therefore, pepper varieties with resistance to multiple diseases are highly desired. In this study, we developed 20 SNP type assays for three pepper populations using Fluidigm nanofluidic dynamic arrays. A total of 4,608 data points can be produced with a 192.24 dynamic array consisting of 192 samples and 24 SNP markers. The assays were converted from previously developed sequence-tagged-site (STS) markers and included markers for resistance to Phytophthora root rot (M3-2 and M3-3), anthracnose (CcR9, CA09g12180, CA09g19170, CA12g17210, and CA12g19240), powdery mildew (Ltr4.1-40344, Ltr4.2-56301, and Ltr4.2-585119), bacterial spot (Bs2), CMV (Cmr1-2), PMMoV (L4), and PepMoV (pvr1 and pvr2-123457), as well as for capsaicinoids content (qcap3.1-40134, qcap6.1-299931, qcap6.1-589160, qdhc2.1-1335057, and qdhc2.2-43829). In addition, 11 assays were validated through a comparison with the corresponding data of the STS markers. Furthermore, we successfully applied the assays to commercial $F_1$ cultivars and to our breeding lines. These 20 SNP type assays will be very useful for developing new superior pepper varieties with resistance to multiple diseases and a higher content of capsaicinoids for increased pungency.

  • 본 연구에서는 고춧가루의 매운맛을 내는 주성분인 캡사이신 함량을 신속하게 측정할 수 있도록 근적외선 흡광도를 측정할 수 있는 시스템을 구성하였다. 이를 이용하여 동일지역(영광군)에서 생산된 맵지 않은 일반 품종의 고춧가루와 우리나라에서 아주 매운 고추로 알려진 청양 품종의 고춧가루를 혼합하여 만들어진 시료에 대하여 입자의 크기별로 캡사이신 함량을 예측할 수 있는 PLSR 모델을 개발하였다. 고춧가루 입도별로 캡사이신 함량의 예측성능을 향상시키기 위한 스펙트럼 전처리 조건을 구명하였으며, 입도가 캡사이신의 함량 예측에 미치는 영향을 구명하였다. 그결과를 요약하면 다음과 같다. (1) 고춧가루의 근적외선 흡광도 측정 시스템은 1100-2300 nm 대역에서의 근적외선 흡광도 측정용 AOTF-NIR Spectrometer, 여러 부위의 흡광도를 측정하기 위하여 제작된 시료 회전판, 시료 회전판을 회전시키는 모터, 회전판의 속도를 조절하는 속도조절장치와, 시료 용기 등으로 구성되었다. (2) 1100-2300 nm의 대역에서 고춧가루와 순수 캡사이신 분말의 스펙트럼을 측정한 결과 고춧가루의 스펙트럼 피크들과 캡사이신의 스펙트럼 피크가 유사한 대역에서 나타나, 근적외선 분광법을 이용하여 고춧가루의 캡사이신 함량 예측이 가능한것으로 판단되었다. (3) 고춧가루 입도별(0.425 mm이하, 0.425-0.71 mm, 0.71-1.4 mm)로 획득한 근적외선 흡광도에 대하여 전처리를 달리하여 개발한 캡사이신 함량 예측용 PLSR 모델을 교차 검증한 결과 결정계수(${R_V}^2$)는 0.948-0.979, 예측오차(SEP)는 6.56-7.94 mg% 범위에서 나타났으며, 입도가 작을수록 예측성능이 우수하였다. (4) 3가지 입도를 통합한 고춧가루(입도 1.4 mm이하)에 대하여 캡사이신 함량 예측모델 개발을 위한 최적의 스펙트럼 전처리 조건은 영역 정규화, SNV와 1차 미분 3가지를 순차적으로 적용하는 것이었으며, 이를 이용하여 PLSR 예측모델을 개발하여 교차검증으로 검증할 때 결정계수(${R_V}^2$)는 0.959, 예측오차(SEP)는 8.82 mg%로 나타났다. (5) 입도가 구분된 고춧가루에는 입도별 예측모델을 적용하고, 입도가 구분되지 않은 고춧가루는 통합 입도 예측모델에 적용함으로써 캡사이신 함량의 예측정확도를 향상시킬 수 있을 것으로 판단되었다.

  • The effect of Ruthenium Red on the antinociceptive action of capsaicinoids was investigated using tail-flick test in mice. Capsaicin and KR-25018, when administered subcutaneously, had a potent antinociceptive effect against noxious heat stimulus. Ruthenium Red which is known to block the calcium channel coupled to the capsaicin receptor, when injected intraperitoneally more than 5 mg/kg, showed severe sedation and apparent antinociceptive effect against noxious heat stimulus. The 2.5 mg/kg Ruthenium Red, at which dose any significant sedative effect was not shown, had no effect on the antinociceptive effects of capsaicin and KR-25018. Considering this result, the antinociceptive effect of capsaicinoid may not be related to the Ruthenium Red sensitive calcium channel which is activated by capsaicin.
