  • This research investigated the application of semi-dried red pepper in Kimchi manufactured using semi-dried red pepper with seed ratios of 20, 40, 60 or 80%. Among the treatments, there were no significant changes in pH, acidity and lactic acid bacterial cell counts during the fermentation period. Kimchi made with a higher pericarp ratio had higher levels of vitamin C, ASTA value and capsainoids during fermentation. The organic acid level showed no significant difference with the various semi-dried red pepper seed ratios, and during fermentation the malic and succinic acid levels decreased while the acetic and lactic acid levels increased. In a sensory evaluation, the overall acceptance was highest for the control group, but the acceptance of Kimchi prepared with semi-dried red pepper at a seed ratio lower than 20% was not significantly different.

  • The fermentation and quality characteristics of kimchi, made by adding different types of red pepper (semi-dried red pepper, fresh red pepper, dried red pepper) according to drying conditions, were examined for 15 days at $10^{\circ}C$ fermentation. The initial pH was approximately 5.65~5.72 in all groups, and the pH decreased with increasing fermentation time. The color value of a/b showed the highest in kimchi that made with semi-dried red pepper (SDRP-K). The color value of A remained at the initial level for 9 days, regardless of treatments. The color value had a tendency to decrease after 9 days. The lactic acid bacteria increased rapidly during 6 days of storage, but showed no difference among groups. The initial contents of malic acid and succinic acid were in 3.23~4.52 and 6.12~7.97 mg/mL and decreased during fermentation in all groups. The lactic acid and acetic acid were not contained in the beginning, but increased with increasing fermentation periods. The vitamin C content of SDRP-K was 5.20 mg/g, which was significantly higher compared with kimchi that made with dried red pepper (DRP-K), but which did not show any significant difference to kimchi that made with fresh red pepper (FRP-K). As a result of antioxidant activity in optimally ripened kimchi, both $DPPH^+$ and $ABTS^+$ scavenging activities were higher in SDRP-K than any other groups. As a result of the sensory evaluation, overall acceptability was highest in SDRP-K.

  • Quality changes in semi-dried red pepper (SRP) treated with ozone water were observed upon storage (at $-18^{\circ}C$) after freezing at $-10^{\circ}C$, $-20^{\circ}C$, and $-40^{\circ}C$. Drip loss after treatment was greater than in control peppers, but no significant difference was evident between treatments (p<0.05). We observed that differences between samples decreased as storage time increased. Texture after treatment did not change significantly over a 3-month period. The redness (a-value) after treatment was greater than in the control, but no sample showed significant color alteration after the 3-month period. The capsaicinoid content decreasedas storage time increased, and was also affected by the freezing temperature. However, carotenoid content was not influenced by freezing or storage temperature. Ascorbic acid and free sugar contents showed decreases of 47% and 6.5%, respectively, after semi-drying. The results of sensory evaluation indicated no significant difference between samples in terms of color appearance.

  • The quality characteristics of semi-dry red pepper (SDRP) (Capsicum annuum L.) were compared with raw and dry red pepper (DRP). Raw red pepper was divided into pieces and the semi-drying treatment involved air-drying at $65^{\circ}C$. The study focused on describing the characteristics of semi-dry red pepper in comparison with dry red pepper. Factors considered were reduced drying period, ASTA color, capsanthin, capsaicinoids, free sugars and vitamin C content. ASTA color, capsanthin, capsaicinoids, free sugars and vitamin C content of SDRP were higher in SDRP than in DRP for 15 g or less water per 100 g. Red pepper powders made using the semi-drying method showed the highest amount of glucose and vitamin C. Capsanthin content in SDRP (151.6155.9 mg/100 g) was significantly higher than for DRP (133.4 mg/100 g). The capsaicinoid content of SDRP was about 13-25% higher than in DRP. The ASTA values (148.7159.3) for SDRP were much higher than for DRP (139.5). The vitamin C and free sugar content of SDRP was 40-76% and 20-40% higher, respectively, than for DRP. and $20{\sim}40%$, respectively, by SDRP compared to DRP.

  • "Gyuhapchongseo" was published in 1809, and introduced the cooking method of the noble class in the late Joseon dynasty. The characteristics of the side dishes in "Gyuhapchongseo" are as follows. Firstly, red pepper was used as whole red pepper, shredded red pepper, powdered red pepper, or Korean hot pepper paste. Secondly, salt-fermented fish was used in some forms of Kimchi, including Sukbakgi, Dong A Sukbakgi, and Gyochimhae. Thirdly, to retain the juiciness of meat during roasting, meat was spread cold water on the surface, dipped into the washing water of rice or wrapped with wet paper. Fourth, to improve the visual effect of a dish, cooked foods were displayed with various color schemes, panfried foods with two tones (egg white and yellow) of color on each side and the use of radish pigmented with deep red color. On examination of the characteristics of food in "Gyuhapchongseo", I would suggest applicable practices for the present cuisine. The use of gravy produced from the boiling down of fish flesh could raise the nutritive value of Kimchi. In "Gyuhapchongseo", Yak po (semi-dried minced beef) is noted as being good for elderly people with bad teeth. A steamed dish with dog meat in Dong A in "Gyuhapchongseo" is made by hollowing out Dong A and putting a dog in it to cook the dog meat to well done in a fire made with the hulls of rice. This technique could be used to present cuisine for steamed and roasted dishes using food ingredients such as pumpkin, sweet pumpkin, and overripe cucumber.

  • We investigated the effect of freezing on changes in the chemical components of semi-dried red pepper (SDRP). We used storage temperatures of $0^{\circ}C,\;-10^{\circ}C,\;-20^{\circ}C,\;and\;-70^{\circ}C$. After 30 days of storage, capsaicin content had decreased by 40% at $0^{\circ}C$ and by 21% at $-20^{\circ}C$. Initial vitamin C content was 1,358.02 mg%. Compared with control, the $0^{\circ}C$ storage group showed a significant decrease in vitamin C content but no such decrease was noted in the $-20^{\circ}C$ and $-70^{\circ}C$ storage groups after 30 days. ASTA values were not influenced by storage temperature or period, in agreement with previous results. We concluded that storage was effective at temperatures of less than $-20^{\circ}C$. Next, both dried red pepper (DRP) and SDRP were stored at $-20^{\circ}C$ for 12 months. DRP had the lower level of capsaicinoids (55.01 mg%) owing to the long drying time. After 12 months, SDRP capsaicinoid had decreased by 30-33%, compared with a decrease of 54% in DRP. Initial vitamin C contents were 721.48 and 955.25 mg% in DRP and SDRP, respectively, and, after 12 months, vitamin C loss in the SDRP group (37%) was less than that in fresh red pepper (FRP) samples (45%). Initial $\beta$-carotene content was greatest in the FRP group (259.82 mg%), and that of DRP decreased by 20% after 12 months. The color a/b value of SDRP (1.40) was greater than that of DRP (1.00).

  • The study was conducted for safety evaluation of 208 kinds of residue pesticides on 200 dried agricultural products, which are distributed in Gwangju. The method of monitoring was the second of Multi Class Pesticide Multi-residue Methods in Korean Food Code, and GC-ECD, GC-NPD, GC-MSD, and LC-MS/MS were used as evaluation equipment to analyze. The residue level in pesticides were 15.5% (31 of 200 samples) and 4 samples exceeded MRLs. 4.5 mg/kg of pyraclostrobin (MRL; 3.0 mg/kg) was detected in red pepper, 1.49 mg/kg of chlorpyrifos (MRL; 0.13 mg/kg) in daikon leaves, 38.26 mg/kg of pyridalyl (MRL; 0.25 mg/kg) in pepper leaves, 0.98 mg/kg of chlorpyrifos (MRL; 0.05 mg/kg), respectively. Pesticides were found on the 15 samples among the 21 samples of red pepper which is a fruit vegetable, and this resulted in high detection rate of 71%. In addition, pesticides were detected on chwinamul, shitake, siler divaricata, daikon leaves and others within MRLs. The frequent detected kinds of pesticides were insecticide (47.6%), fungicide (33.3%), acaricide (14.3%), nematicide (4.8%) in the order named, and pesticides were methoxyfenozide > pyraclostrobin > azoxystrobin, chlorantraniprole > novaluron, trifloxystrobin in frequent order.
