The aim of this study was to determine microbiological contamination of fresh-red pepper and packaged-red pepper powder commercially available in South Korea. Thirty-seven fresh-red peppers were collected from 5 farms and 31 packaged-red pepper powders were purchased from retail markets in South Korea. Foodborne pathogens (Escherichia coli, Salmonella spp., Listeria monocytogenes, Staphylococcus aureus and Bacillus cereus), total viable counts, Enterobacteriaceae, coliforms, yeast and mold, and Aspergillus flavus were determined. Detection percentage of contamination of Bacillus cereus in fresh-red pepper was 8.1%, which was lower than the 39% of detection rate in packaged-red pepper powder. The contamination level of Bacillus cereus was 1~3 log CFU/g in packaged-red pepper powder. Escherichia coli was detected in 5.4% of fresh-red pepper samples and was not detected in packaged-red pepper powder. Enterobacteriaceae and coliforms were detected in both of fresh-red pepper and packaged-red pepper powders. Foodborne pathogens, except Bacillus cereus and Escherichia coli, were not detected.

Geometrical characteristics of fresh red pepper(Capsicum annuum L.) were measured and indexed to define some important geometrical characteristics, and malformation of body and fruit stalk which are necessary for the design of the equipments for cutting, spreading and alignment of red pepper in developing a fruit stalk remover of fresh red pepper. The effects of bending of body and fruit stalk on the equipments of cutting, spreading and alignment were studied. The maximum lengths of some parts of fresh red pepper were found to be 180 mm, 125 mm, 144 mm, 67 mm and 76 mm for the body, the bent part of body, the fruit stalk, the bent part and the straight part of fruit stalk, respectively. The fresh red pepper with bending indices more than 0.4 and 0.3 for the body and the fruit stalk, respectively, was defined to be malformed based on the result of cutting rate using cutting unit; while the other ones to be normal in shape. Based on this, among the total fresh red peppers tested, 47%, 40% and 20% were found malformed for the body, the fruit stalk, and for both of the body and the fruit stalk. Malformed red peppers were poorer in spreading and alignment than normal ones, and the processed quantity was decreased with increased feed rate. The required time for the malformed peppers to pass on the alignment plate inclined at 30 increased rapidly at 8.3 Hz with increased feed rate. For the fresh red peppers with average moisture content of 85%,w.b., the maximum tensile strength between fruit stalk and body was 88.1 N; the maximum cutting resistances were 92.1 N and 94.9 N for the fruit stalk-calyx joint and body, respectively. Average coefficients of static friction were 0.99, 0.62, 0.59 and OJ, respectively, for the surfaces of rubber, galvanized iron, acryl and plywood.
The present study investigated the influence of different volumes of red hot pepper juice on the quality characteristics of fresh Pasta noodle. Supplementation with 0% (control), 2.5%, 5%, 7.5%, or 10% red hot pepper juice produced similar gelatinization characteristics of peak viscosity, temperature at peak viscosity, hot paste viscosity and numerical value of breakdown. However, increasing concentrations of red hot pepper juice produced progressively and significantly low cold paste viscosity and setback. The chromaticity of wet and cooked noodles was significantly lower in L value and significantly higher in +a and +b values with increasing volumes of red hot pepper juice. The texture of fresh noodles displayed no significant differences in hardness, adhesiveness and chewiness. The springiness and cohesiveness were lower and higher with the increase of added red hot pepper juice, respectively, but the differences just attained significance. For cooked noodles, adhesiveness, springiness, cohesiveness and chewiness tended to be higher with increasing volumes of red hot pepper juice, but again the differences just attained significance. Cooking characteristics of weight, volume, moisture absorptive power and turbidity decreased with increasing volumes of red hot pepper juice. Sensory characteristics of acceptability including appearance, color, flavor, taste, texture and overall-acceptability improved with increasing red hot pepper juice volume, in particular with 5% and 7.5%. Amylograph characteristics for initial paste temperature positively correlated with the texture characteristics for chewiness (p<0.05). Negatively correlated amylograph parameters included texture for springiness with for peak viscosity (p<0.01), texture for adhesiveness with hot paste viscosity (p<0.01) and breakdown with texture for adhesiveness, cohesiveness and chewiness (p<0.05).
In this study, the changes in the quality characteristics of $Kimchi$ added with fresh red pepper ($Capsicum$$annuum$ L.) was investigated during 5 months of fermentation at $2^{\circ}C$. The moisture content of $Kimchi$ increased with an increase in the amount of added fresh red pepper, whereas the crude protein, crude lipid, and crude ash content decreased. The initial pH and total acidity of $Kimchi$ containing the fresh red pepper showed ranged from 4.96-5.36 and 0.27-0.33%, respectively. The pH and total acidity rapidly changed within a range of 4.27-4.37 and 0.53-0.55%, respectively, up to 2 months. The fructose and glucose content slowly changed up to 2 months and 3 months, respectively, and then gradually decreased afterwards. The total bacterial and lactic acid bacterial counts of $Kimchi$ containing the fresh red pepper gradually increased up to 2 months and 3 months, respectively, and then decreased thereafter. In addition, there was no difference between the $Kimchi$ containing the fresh red pepper and the control in the sensory evaluation.
In order to monitor the pesticide residues in/on peppers and pepper powder and to assess their risk, pesticides in/on green pepper from 10 farmgates and fresh red pepper from 9 farmgates in Chungbuk area and pepper powder from 6 wholesale markets in Cheongju city were analyzed with a GLC and an HPLC. Also, pepper powder made by pulverization of the dried red pepper was analyzed to elucidate the change of pesticide residues in fresh red pepper by oven-drying. The number of pesticides detected from peen pepper, fresh red pepper, dried red pepper and pepper powder were 9, 12, 12, and 17, respectively, including 10 pesticides (one fungicide and nine insecticides) which were exceeded the maximum residue limits (MRLs). The exceeding rate of the MRL were higher in dried red pepper and pepper powder than in green pepper and fresh red pepper. Although some pesticides in peppers and pepper powder exceeded the MRLs, their estimated daily intake(EDI) were less than 1.6% of their acceptable daily intakes(ADIs), suggesting that it would be estimated to safe. By oven-drying of fresh red pepper at $65^{\circ}C$ for 72 hours, the weight of dried red pepper was from 1/5.9 from 1/7.8 of fresh red pepper, while the concentration of pesticide residue in dried red pepper increased from 1.7 to 8.2 times, suggesting that further reconsideration was required for the MRL of pepper powder.
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.
The effects of modified atmosphere(MA) storage for fresh red chili pepper and red bell pepper fruits were investigated with storing in polyethylene film with various fine holes. During the storage of the both pepper fruits, the weight loss, color change, mold emergence, and firmness were evaluated. The weight loss of pepper fruits packaged without holes on film was less than 3%, even though it was each 50% and 25% for non packaged red chili pepper and red bell pepper fruits. The rates of mold emergence of red chili pepper and red bell pepper fruits were reached to each 60% and 50% at the end of storage period as stored in film without holes. However, the rate of mold emergence of pepper fruits was lowered when fruits were stored in MA with low relative humidity (70∼80%). The color and firmness of pepper fruits were not much changed when fruits were stored in MA with high humidity.
The purpose of this study was to determine which fermented liquid fertilizer and application method yields the greatest amount of growth in red pepper (Capsicum annuum L.) and tomato (Lycopersicon esculentum MILL.) plants. Additionally, we investigated which extraction methods produce the most effective fertilizer with the highest levels of mineral nutrients. The liquid fertilizers used in this study were made from fish, bone and fish meal, red pepper leaves, and oil cake, and were extracted using fermentation or water and boiled water. In tomato plants, foliar-application of fermented fertilizer is known to promote more growth than application by drenching, regardless of the number of treatments (once or twice). In our studies, however, drenching with fertilizer promoted growth more effectively than foliar-application in red pepper plants. Studies in both tomato and red pepper have shown that the number of treatments does not significantly alter growth. Liquid fertilizers produced by a fermentation-extraction method promoted greater levels of growth in tomato compared to red pepper, and growth was greater when fertilizers were applied 20 (rather than 40) days post-sowing. Red pepper and tomato shoot fresh weight were affected more by fermented fertilizers than plant height 20 days post-sowing. In red pepper, we observed increased shoot fresh weight when using fermented liquid fertilizers with concentrations of 0.1% or greater. Tomato shoot fresh weight increased similarly in response to fermented fertilizer treatments at the same concentration levels, except those derived from fish. Fermented fish liquid fertilizer was only effective in increasing tomato shoot fresh weight in concentrations exceeding 1%. Red pepper and tomato shoot fresh weight also increased more than plant height in our studies using fermentation liquid fertilizers at 40 days after sowing. Red pepper fresh weight increased with application of bone + fish meal, red pepper leaf, and oil cake fertilizers at concentrations of 0.1%, but not with fish liquid fertilizer in concentrations under 0.5%. Shoot fresh weight in tomato increased with all liquid fertilizers. Growth in red pepper and tomato may be influenced by different kinds of fertilizers due to combinations of macro- and micro-nutrients, or specific macro-nutrients such as nitrogen, phosphoric acid, and potassium. The mineral nutrients found in fish, bone and fish meal, red pepper leaves, and oil cake were not easily extracted by fermentation; thus, liquid fertilizers made using water and boiled water methods more effectively promoted growth in red pepper and tomato due to the larger amounts of macronutrients eluted.
Water and ethanol extracts of fresh red peppers were obtained by two methods, conventional extraction (CE) and microwave-assiated extraction (MAE), under different extraction conditions. Red pepper oleoresins extracted by CE and MAE were examined in oleoresin yield and physiological activities. The proper extraction time of MAE was about 5 minutes, whereas that of CE was 2 hours. therefore extraction time was decreased drastically by MAE but there was no significance in oleolesin yields. the electron donating abilities also showed negligible difference between two extracts obtained by CE and MAE, and 80% level in all extracts . the nitrite scavenging effect was reduced by increased of ph , and showed a high elimination effect over 85% at ph 1.2. All extracts had a high tyrosinase inhibitory effects of 100%. The angiotensin I-conventing enzyme effect showed higher activity with over 80% in MAE than 70% level in CE. the capsanthin was extracted with ethanol and was 11.4 and 12.9 ${\mu}$moles per 1 g of fresh red pepper by CE and MAE, respectively.
To prevent red pepper from post harvest decay and to reduce the labor and drying expenses, the red pepper paste was directly prepared from fresh red pepper. The characteristics of red pepper paste and processing properties were investigated, and the effect of salt and heat on product quality during processing and storage were studied. After the processed red pepper paste was stored at room temperature, $5^{\circ}C\;and\;-3^{\circ}C$ without light for 6 months, kimchi was prepared with the stored red pepper paste to evaluate any quality change. The weight and pH of pericarp were 73.2% of total and 5.0, respectively. Addition of 10% salt to the paste decreased the pH of paste, reducing the sterilization time down to 10 min against growth of Clostridium botulinum. Thermal diffusivity of paste after pasteurization was $1.190{\times}10cm^{-7}/sec$, which was lower than control, probably due to air in pouch. The red pepper paste with 10% salt added, followed by sterilization for 10 min, could be preserved for over 6 months at $5^{\circ}C$.
