  • Efficient plant regeneration has been achieved via organogenesis in the red pepper plant (Capsicum annum L.). Shoots were induced from seed explants of cultivar 'Friendship' on Murashige and Skoog's (MS) basal medium supplemetned with; NAA or IAA, and BAP or zeatin. Seed explants on the medium supplemented with 0.1-0.3 mg/L IAA and 2-5 mg/L zeatin for 2 weeks vigorously formed normal shoots in more than 90% of the explants. When these were transferred to MS medium containing 0.5-1.0 mg/L GA, 90-100% of the shoots have elongated within 1-2 weeks. The elongated shoots rooted in media supplemented with 0.3 mg/L NAA. It was revealed that this method is very rapid and efficient regeneration system for red pepper and regenerated plants can be obtained after only 5-6 weeks of culture.

  • This study investigated the physico-chemical and sensory quality of Doenjang added with red pepper (Capsicum annuum L.) seed. The initial moisture content and salt content of Doenjang were 52.03-53.79% and 13.28-14.05%, respectively. The moisture and salt contents of Doenjang slightly decreased and increased, respectively, as fermentation periods increased. According to increasing fermentation periods, pH of Doenjang showed a little decreasing value although there were no difference between samples with various red pepper seed contents. On the other hand, titratable acidity of Doenjang increased as fermentation periods increased. Also, Doenjang added with red pepper seed had higher titratable acidity value than control Doenjang without red pepper seed. In the color of Doenjang, ‘L’ of lightness, ‘b’ of yellowness, and ‘a’ of redness were decreased as fermentation periods increased. Also, generally, increase of red pepper seed concentration resulted in higher values of redness (a), yellowness (b) and lightness (L) of Doenjang. Also, amino-type nitrogen content, which was 497-623 mg% in initial fermentation period samples, increased to 1,000 mg% for control and to 756~896 for red pepper added at the fermentation 120 days. In the total microbes, total cell count in the Doenjang samples was in the range of $10^7{\sim}10^8$ CFU/g regardless of fermentation periods. In contrast, yeast and mold number of Doenjang samples showed the range of $10^5$ CFU/g at the initial fermentation periods and decreased thereafter. In the sensory evaluation of Doenjang, unique Doenjang flavor increased regardless added red pepper seed as fermentation periods increased.

  • The purpose of the present study was to evaluate the effects of red pepper seeds powder on lipid metabolism in rats fed high fat high cholesterol diet. Rats were divided into five experimental groups: normal diet group, high fat high cholesterol diet group, high fat high cholesterol diet with 5% red pepper seeds powder supplemented group (SA group), high fat high cholesterol diet with 10% red pepper seeds powder supplemented group (SB group) and high fat high cholesterol diet with 15% red peeper seeds powder supplemented group (SC group). The serum triglyceride (TG) and cholesterol contents, and LDL-cholesterol and atherogenic index (AI) of the red pepper seed powder supplemented groups were significantly decreased compared to the HF group. The serum HDL-cholesterol contents of the red pepper seed powder supplemented groups were increased compared to the HF group. However, there was no significant difference in the serum HDL-cholesterol among all experimental groups. The hepatic TG and cholesterol contents of the red pepper seed powder supplemented groups were significantly decreased compared to the HF group. The fecal total cholesterol and triglyceride contents of the red pepper seeds powder supplemented groups were significantly increased compared to the HF group. These results suggest that supplementation of red pepper seed powder may have a pronounced impact on markers of lipid metabolism in serum and liver of rats fed high fat high cholesterol diets.

  • Seed separation out of fresh red pepper by impact methods was effective but impossible to separate over 45% of seed. For the increase of seed separation, dehydration effect was studied with the slices of pepper. Heat deformation during the course of drying at hot air of 0. 61m/sec velocity at temperature of $65^{\circ}C$, increased the separation up to 93% with a halfcut pepper. Seed separation was remarkably different upon the location of cut, but it was completed prio tothe completion of drying in every cutting orientations. From these results a simultaneous seed separation and drying operation techniques is successfully developed.

  • 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%.

  • Colletotrichum dematium, C. gloeosporioides and Glomerella cingulata were detected in seed samples collected from diseased red pepper (Capsicum annuum) using blotter method. C. gloeosporioides was the predominant species in seed samples tested and followed by C. dematium and G. cingulata. When the seed components were plated C. dematium, C. gloeosporioides and G. cingulata were detected from seed coat, endosperm and cotyledon. The three anthracnose fungi were recorded more frequently from seed coat than that of observed in the endosperm and cotyledon. Seed infection with C. dematium, C. gloeosporioides and G. cingulata caused seed rotting, damping off and seedling blight of red pepper plants. According to the inoculation experiments, it was shown that C. gloeosporioides was the most virulent among three species. C. dematium showed weak virulence when the plants were wounded, and G. cingulata was wound parasite or weakly virulent on red fruits. Benlate T (benomyl+thiram) and Homai (thiophnate-methyl+thiram) were effective to anthracnose fungi when treated to infected seeds.

  • The stability of red pepper seed oils during storage at 20${\pm}$3$^{\circ}C$, 40${\pm}$3$^{\circ}C$ and heating at 140${\pm}$3$^{\circ}C$ or 180${\pm}$3$^{\circ}C$ were measured to evaluate red pepper seed oil as a cooking oil. Two species of red pepper seeds (native, improved) were dried by either sunlight or heating to prepare the oil samples of NS (native, sunlight-dried), IS (improved, sunlight-dried), NF (native, heated), and IF (improved, heated). During storage at 20${\pm}$3$^{\circ}C$ or 40${\pm}$ 3$^{\circ}C$, acid values (AV) of all red pepper seed oils were higher than that of soy bean oil (SBO), however, peroxide values (POV) were similar to SBO. Antioxidative stability of NS was better than SBO but IF was not. By the heat treatments at 140${\pm}$3$^{\circ}C$ or 180${\pm}$3$^{\circ}C$, NS was identified to have better antioxidative stability than SBO and IF was the lowest. In sensory evaluation of each deep-fat fried potato-chip at 180${\pm}$5$^{\circ}C$, potato-chips fried in NS were better than that of SBO for color, taste, and flavor. NS-fried potato-chips got the highest score in overall acceptance (p<0.05), however, those of IF showed little acceptance. When blended oils (SBO: NOS, 0, 25, 50, 75%) were used, 50% blended oil was the best for taste, color, flavor, cripness, and total acceptance.

  • For maximum seeding efficiency of a nozzle type seeder, the performance of the nozzle should be considered sufficiently. This study was carried out to investigate the optimum operating conditions of a seeder attached the vacuum nozzle which was modified syringe needle acting on the plug seedling tray and the seed plate. Such operating factors as the hole diameter of the nozzle (d), the distance from the nozzle tip to the bottom plate of seed hopper(D) the absorbing air pressure of the nozzle tip(P) the bounding height of seed from the vibrated bottom plate of seed hopper and the seeding speed were selected based on the weight of a grain of seed(W). The treated materials were pepper seed as the flat type, cucumber seed as the oval type and radish seed as the spherical type. The optimum operating conditions of the experimental seeder were revealed as follows: 1. The height of the seed bounding from the bottom plate of seed hopper and the distance from nozzle tip to bounded seed were 5 mm and 0.5 mm at all seeds. The hole diameter of the nozzle and the absorbing pressure for pepper seed, cucumber seed and radish seed was 0.45 mm, 0.65 mm. 0.65mm and 39.2 kPa, 88.3 kPa, 58.8 kPa, respectively. 2. The absorbing pressure P was represented as P=η.4W/$\pi$d$^2$ where η was 100. The seeding speed using a 128 cell tray was 2.4 cm/s which was same transfer as 2.5 trays per minute. 3. The maximum seeding rate in case of the pepper seed was 97% the cucumber seed was 95% and the radish seed was 100% under the optimum operating conditions of the seeder.

  • This study was carried out to assess the potential of SSR markers for variety identification by comparing SSR markers and morphological traits in tests of distinctiveness, uniformity, and stability (DUS) of pepper (Capsicum annuum L.) varieties. Twenty-seven SSR markers were polymorphic in 66 pepper varieties, revealing a total of 89 alleles. Average polymorphism information content (PIC) value was 0.529, ranging from 0.03 to 0.877. Cluster analysis of the band patterns separated the varieties into three groups corresponding to varietal types. Morphological trait-based clustering showed some degree of similarity to dendrogram topologies based on the SSR index. However, no significance correlation was found between the SSR and morphological data. SSR markers could be used to complement a DUS test of a candidate variety and to select complimentary varieties by pre-screening existing varieties in the context of protecting new varieties of pepper.
