  • Provitamin A carotenoids($\alpha$- $\beta$-carotene lutein capsanthin) cintents in various red pepper and red pepper products were analyzed by HPLC and UV/VIS spectroscopy. The amounts of $\beta$-carotene and capsanthin were at its highest in powdered red pepper and lutein in red pepper leaves. There are little $\alpha$-carotene present in all samples analyzed. So vitamin A activity was calculated only from $\beta$-carotene content. Capsanthin and $\beta$-carotene contents of red pepper were higher than those of green pepper whereas lutein content of red pepper was lower than that of green pepper. whereas lutein content of red pepper was lower than that of green pepper. Vitamin A activity from colorimetric analysis was higher than that from chromatographic method and results were not generally in accordance with the vitamin A data presented in current food composition tables. Vitamin A activities in retinol equivalent(R. E. ) of green pepper red pepper powdered red pepper fermented red pepper paste and red pepper leaves were 70, 570, 1, 340, 140, 980 R. E respectively.

  • In order to optimize use of pepper resources, and to aid farmers in increasing their income, we compared two types of kimchies made from red and green pepper powder. Qualitative differences were examined during fermantation at $4^{\circ}C$. There was no significant change in pH patterns, acidity, total bacteria cell count and total lactic acid bacteria cell count between the red and green pepper powder, however, sensory evaluation, indicated that Kimchi made with green pepper powder showed lower, sensory scores than Kimchi made with red pepper powder with respect to overall acceptability. Eventhough the sensory scores of green pepper is lower than that of red pepper, the quality of Kimchies was not different between them. Considering that the price of green pepper is far cheaper than red pepper powder, farmers should consider actively the production of green pepper Kimches in order to cut down expenses fur the production of Kimches.

  • 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.

  • Hot pepper has anti-obesity effects by controlling appetite and reducing blood fat level. To reduce the pungency of capsaicin, red or green hot pepper juice was fermented with Bacillus licheniformis SK1230. Fermented hot pepper juice was then added into yogurt at different ratios. The pH of yogurt added with hot pepper juice was decreased from 4.61 to 4.48. Titratable acidity and counts of lactic acid bacteria were increased with increasing amount of pepper juice added. However, the viscosity was decreased significantly compared to the control. On chromaticity test, when more pepper juice was added, $L^*-value$ was decreased whereas $a^*$- and $b^*$- values were increased significantly (p<0.05). The spectrum of antimicrobial activity of yogurt was slightly changed compared to using pepper juice. Total polyphenol contents and antioxidant activity were increased with increasing amount of pepper juice added. Stirred yogurt added with fermented red pepper juice at 3% or green pepper juice at 1% showed high scores in flavor, appearance, texture, and overall acceptance in sensory test. Yogurt added with fermented pepper juice with reduced pungency showed also good palatability during storage at $4^{\circ}C$. Yogurt with added hot pepper juice can be play an important role in functional food relative to anti-obesity.

  • Organic farming is rapidly expanding worldwide. Crop growth in organic systems greatly depends on the functions performed by soil microbes, and nutrient supply weed suppression by green manure crops input. Four red-pepper production systems were compared: 1) bare ground (conventional system); 2) hairy vetch monoculture; 3) rye monoculture; and 4) hairy vetch-rye mixture. Soil inorganic N reached the peak at 30 DAI and hairy vetch monoculture was the highest ($192mg\;kg^{-1}$) and soil total carbon was fluctuated sporadically during the experiment. Carbohydrate and phenolic compounds in soil kept significantly higher in green manure crops systems from 10 DBI to 30 DAI, however the level was the maximum at 10 DBI (carbohydrate) and 30 DAI (phenolic comounds). Incorporation of green manure crops residue enhanced soil microbial biomass C and N throughout the growing season except that MBN in rye was reduced after incorporation. Green manure crops systems suppressed weed occurrence and, in particular, it was prominent in rye monoculture. Mineral elements composition and production in red-pepper fruits were markedly decreased in green manure crops systems although hairy vetch monoculture has come close to bare ground (NPK-applied). Therefore, it was suggested that higher biomass production should be performed not only to improve soil quality and suppress weeds but to yield suitable red-pepper fruits in green manure crops-based organic farming.

  • To determine the effect of winter green manure crops for tillage and no-tillage organic pepper cultivation in plastic film house, five different green manure crops were cultivated during winter season. In nutrition composition of green manure crops, total nitrogen contents were higher in Vicia hirsuta and Vicia angustifolia than any other crops. The average dry weights of green manure crops were 8.3 ton per ha in tillage and 7.0 ton per ha in no-tillage, among green manure crops that of Secale cereale was the highest. Fertilizer supply was depended on the biomass of the cultivated green manure crops and nutrition contents, total nitrogen supply of V. angustifolia was 226 kg and that of S. cereale was 251 kg per ha in tillage field. In no-tillage field, N-supply of V. angustifolia was 197 kg and that of S. cereale was 222 kg per ha. In yield components of red pepper, fruit numbers per plant were 55.5 in green manure crop tillage and 37.0 in no-tillage cultivation. Among green manure crops, the yield of dried red pepper was the highest for V. angustifolia in both green manure crop tillage and no-tillage cultivation.

  • ${\beta}-Carotene$, vitamin E, and folate contents according to color and species of Capsicum annuum were investigated. In addition, four C. annuum species were cooked by using different methods (boiling, pan-cooking, pan-frying, deep-frying, steaming, roasting, and microwaving), and retention rates of ${\beta}-Carotene$, vitamin E, and folate affected by color and species were evaluated. Weight loss was observed in all paprika and pepper species using all cooking methods. ${\beta}-Carotene$ and folate contents of C. annuum samples were significantly different by color, species, and cooking method (P<0.05), whereas vitamin E contents were not significantly affected by species. ${\beta}-Carotene$, vitamin E, and folate contents (mg/100 g) of raw C. annuum showed ranges of 95.4 (green pepper)~2,441.1 (red pepper), 0.7 (green paprika)~4.2 (red paprika), and 6.2 (green pepper)~148.7 (red pepper). As a result, the highest ${\beta}-Carotene$, vitamin E, and folate contents were detected in deep fried red pepper, roasted red pepper, and boiled red pepper, respectively, among the cooked samples. Retention rates of C. annuum varied by cooking method, resulting in ranges of 77.3% (boiled red pepper)~356.4% (roasted green pepper) for ${\beta}-Carotene$, 2.0% (microwaved red pepper)~789.3% (deep-fried green paprika) for vitamin E, and 20.9% (microwaved red pepper)~445.1% (steamed green pepper) for folate. Over 75% retention rates were observed for ${\beta}-Carotene$, vitamin E, and folate in all samples except for red pepper. However, in red pepper, vitamin E and folate retentions were remarkably lowered by deep frying and micro-waving, resulting in rates of 2.0~32.1%. This study provides information on effective cooking methods for vitamin retention in C. annuum depending on color and species.

  • This study was conducted to standardize ingredient ratio and preparation method of mafor traditional special kimchies in kyungsang province, korea. There were about 35 varieties of special kimchi in Kyungsang province. Six varieties of them such as burdock kimchi, wild leek kimchi, green thread onion kimchi, perilla leaf kimchi, Godulbaegi(Korean wild lettuce) kimchi, and red pepper leaf kimchi were selected, because they tasted good and the physiological functions of their main ingredients were excellent. The ingredient ratios of the selected special kimchi were standardized through surveying hereditary preparation of some families in kyungsang province and using the literatures including cooking books. The standardized ingredient ratio of the burdock kimchi was 15.1 pickled anchovy juice, 6.8 red pepper powder, 5.7 garlic, 2.2 ginger, 18.0 rice flour paste, 13.5 green thread onion, and 1.2 sesame seed in proportion to 100 of burdock. The standardized preparation step of the selected special kimchies was similar except some preprocessing methods of main ingredients. The diagonally cut-up burdock ws usually parboiled or soaked in salted water, then it was mixed with the other ingredients. Wild leek and green thread onion were usually pickled with salt or pickled anchovy juice. Sometimes the green thread onion pickled was dried in the sun. General preprocessing of perilla leaf, Korean wild lettuce, and red pepper leaf was soaking them in salted water for about 5-10 days. Sometimes red pepper leaf was heated with steam and dried in the sun, then it was mixed with the other ingredients.

  • The antimutagenic effects of juices from green pepper(GP), red pepper leaf(RPL), red pepper(RP) and sweet pepper(SP) were examined by the Ames method using Salmonella typhimurium TA100. The juice supernatants of GP, RPL and RP showed antimutagenic activities against afltoxin B1(AFB1) in Salmonella typhimurium TA 100. The juice supermatants of GP and RPL also exhibited the inhibitory effects(p<0.05) to the mutagenicities induced by N-methyl-N'-nitro-N-nitrosoguanidine(MNNG) and 4-nitro-quinoline-1-oxide(4-NQO). The juice of RP showed antimutagenic activities against indirect mutagen of AFB1, however, the activity was reduced at higher concentration(5.0%), furthermore, as the adding concentration of sample increased to 5.0%, it exhibited slight comutagenicith on direct mutagen of MNNG. Theantimutagenic activities of GP and RPL juices were reduced significantly after heating at 100℃ for 20min, supposing that the antimutagenic compound(s) in the juices were heat labile.
