  • The purpose of this study was to estimate the preference, intake frequency and eating behavior for kimchi as well as analyze the differences by gender among fourth to sixth grade students (n=410) in a Chungnam region. Approximately 64% of the students liked the spicy taste of kimchi, 75.9% liked the saltiness, and 48.5% liked well-fermented kimchi. The disliking factors of kimchi were its sour taste (38.5%), strong scent (20.1%), and salty taste (15.4%). The most preferred type of kimchi was Baechukimchi, followed by Kkakduki, Yeolmukimchi, and Chonggakkimchi. Further, the most frequently consumed type of kimchi was Baechukimchi, followed by Kkakduki, Chonggakkimchi and Yeolmukimchi. Oisobaki, welsh onion kimchi, sesame leaf kimchi, Gatkimchi, Nabakkimchi and Baekkimchi were rarely consumed. About 34% of the students consumed 5 to 7 pieces of kimchi per meal, and 84.1% enjoyed eating kimchi, mostly because of its good taste (61.3%). The reason for not eating kimchi was because other side dishes are more delicious (30.2%). About 80% of the students responded that they prepared kimchi at home. Moreover, 74.3% of the students eat kimchi much more at home than at school. Improvements to be made for kimchi at school were as follows: less salty (34.9%), less spicy (27.6%), and sweet (22.5%). In conclusion, students enjoyed eating kimchi because of its good taste. Further, they showed preference for Baechukimchi, Kkakduki, and Yeolmukimchi and consumed them frequently. Because kimchi appears to be more preferred and more frequently consumed, it is necessary to develop a menu using kimchi along with the proper eating guidance for helping students consume various types of kimchi at school or at home.

  • The objective of the present study was to investigate differences in quality of kimchi products produced in Korea, Japan, and China. Kimchi products from kimchi-producing countries with high consumer consumption such as Japan and China along with local products from Korea, where exporting has not yet started, were collected. Product pH, acidity, salinity, package pressure, gas production were assessed, and microbiological analyses and sensory evaluations were performed on kimchi products that were stored at either $4^{\circ}C$ for 63 d or $15^{\circ}C$ for 20 d. The pH and acidity results showed that as Japanese and Chinese kimchi had higher pH and lower acidity than that of Korean kimchi, which was determined to be indicative of insufficient microbial fermentation following kimchi production. Japanese kimchi had different microbial properties than those of Korean kimchi, which is due to differences in their manufacturing processes. Overall preferences derived from sensory evaluations were: Korean kimchi>Chinese kimchi>Japanese kimchi. The results of this study demonstrate the sensory superiority of Korean kimchi and may be useful when predicting consumers' acceptance level of Korean kimchi exported to other countries.

  • He purpose of this study was to provide basic data for improvement commercial kimchi quality. To examine the consciousness of commercial kimchi, college students residing in the Jeonnam area were selected and asked to questionnaires. Commercial kimchi samples used included a total of 7 kinds which were fermented for 2 week at $4^{\circ}C$. A sensory characteristics included 10 items with a 5-score scale: color, savory taste, carbonated taste, sour taste, hot taste, salty taste, bitter taste, off-flavor, texture, and overall preference. 76% of the whole student liked kimchi, especially well-fermented kimchi(43.2%) and kimchi with fermented fish(48.6%). Participants liked savory(21.6%), hot(17.1%), and crispy(14.4%) taste. Their most favorite kimchi was the whole cabbage kimchi(26.1%), wild lettuce kimchi(0.9%) and watery kimchi made of sliced radishes(1.8%) were low in preference. 56.8% of participants had no experience in making kimchi. They mainly bought commercial kimchi in grocery stores(37.8%) or shopping malls(29.7%). They pointed out the addition of artificial sweeter(35.1%), insanitation, and discredit of kimchi materials(21.6%) as problems of commercial kimchi. The sensory characteristics of commercial fresh kimchi was significantly different in color($2.6{\sim}4.1$), and hot($2.3{\sim}3.8$), and salty($2.6{\sim}3.5$) with p<0.001. The sensory characteristics of $4^{\circ}C$-fermented commercial kimchi for 2 week was significantly different in color($2.7{\sim}3.9$), and salty($2.1{\sim}4.0$) with p<0.001. It was found that color, and hot, and salty taste had the greatest effect on the overall preference in non-fermented kimchi, and color and salty taste, in 2 week fermented kimchi

  • Brining property and antimutagenic effects of organically cultivaged Chinese cabbage kimchi (OC kimchi) and common Chinese cabbage imchi (CC kimchi) were studied. The salt absorption rate of leaves was faster than that of stems of the Chinese cabbages. Due to the large portion of leaf in organic Chinese cabbage, organic Chinese cabbage(OC) was much faster in terms of salt absorption rate than common Chinese cabbage(CC). The antimutagenic effects of methanol extracts of CC kimchi and OC kimchi were studied against aflatoxin B1(AFB1) using Ames test on Samonella typhimurium TA 100 and N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) using SOS chromotest. Methanol extract from 6 -day fermented OC kimchi at 15 $^{\circ}C$ showed 80% inhibition rate against the indirect mutage, aflatoxin B1 induced mutagenicit where as that from 6-day fermented CC kimchi at 15 $^{\circ}C$ showed 54% inhibition rate in the Ames test. Methanol extracts from 6-day fermented CC kimchi and OC kimchi showed 27 % and 58 % inhibition rate against direct mutagen , N-methyl-N'-nitro-N-nitrosoguanidine induced mutagenicity, respectively in SOS chormotest, thus OC kimchi exhibited higher antimutagenic activity than kimchi.

  • Capsaicinoids in red pepper powder are known to show anti-bacterial effects; however, their effects during kimchi fermentation are not known. This study aimed to investigate the effects of various concentrations of capsaicinoids on kimchi fermentation. Five sets of kimchi samples were prepared using 0 mg/kg (control), $98.34{\pm}5.34mg/kg$ (mild), $243.47{\pm}3.71mg/kg$ (medium), $428.63{\pm}30.78mg/kg$ (hot), and $1,320.49{\pm}28.27mg/kg$ (extreme) capsaicinoid. The characteristics of each kimchi sample, including pH, acidity, organic acid, sugars, sugar alcohol, capsaicinoid content, and microbial community were periodically investigated during fermentation. Kimchi with red pepper powder shows significantly higher acidity than control kimchi, whereas pH values were the same. Organic acid in kimchi with red pepper powder was higher than in control kimchi, probably caused by higher lactic acid bacteria (LAB) counts in kimchi samples with red pepper powder. Our results show that addition of red pepper powder decreased Leuconostoc spp. counts in the bacterial community. In particular, Lactobacillus sakei and Leuconostoc gelidum counts increased and decreased, respectively, with increasing capsaicinoid content of red pepper powder added to kimchi. Overall, the results of this study indicate that physicochemical properties and LAB such as L. sakei and L. gelidum are influenced by capsaicinoid content. However, further studies are necessary to investigate the effects of the percentage of red pepper powder in kimchi on fermentation to provide practical guidelines for producing standardized kimchi.

  • Kimchi is a major Korean traditional fermented food, as a supplying source of vitamin and minerals which is prepared with various vegetables and condiments such as red pepper, garlic and salted fish etc. There are many types of Kimchi depending on the ingredients and preparation methods used. To investigate the clastogenicity and anticlastogenicity of Baechu (Chinese cabbage) Kimchi and Buchu (leek, Allium odorum) Kimchi in mouse, it was performed acridine orange supravital staining of micronucleus (AOSS-MN) assay using mouse peripheral reticulocytes. Baechu Kimchi and Buchu Kimchi were cultivated by organic agricultural technique, and Kimchi samples were prepared by methanol extraction and lyophilization. First of all, it was studied the clastogenicity of two Kimchi samples themselves (250-1,000 mg/kg) after oral adminstration in mouse. And also to study the anticlastogenic effect of oral administration of Kimchi samples, mitomycin C (MMC, 1 mg/kg, i.p.) was used as micronucleus inducing agent in this study. Dosing scheme was performed as simultaneous (co-treatment), 3 hr before (pre-treatment) and 3 hr after (post-treatment) with MMC treatment. Two Kimchi samples in the range of 250-1,000 mg/kg did not reveal any clastogenic effect in AOSS-MN assay in mouse. They also revealed anticlastogenic effects in post-treatment of Baechu Kimchi (1,000 mg/kg), and in pre-treatment of Buchu Kimchi (500 and 1,000 mg/kg) with statistical significance. The anticlastogenic effect revealed 1 and 6 hr after treatment of Baechu Kimchi, and Buchu Kimchi with 3 and 6 hr pretreatment. Consequently, it is suggested that antimutagenic and anticlastogenic mechanisms of Baechu and Buchu Kimchi in vivo attributed to sipindle formation and kinetic behavior of mutagens such as absorption and metabolism etc.
