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

Kimchi industry in Korea has grown rapidly with the increasing domestic and overseas demand of Kimchi. Currently, there is an increase trend of consuming the commercial Kimchi products, although the Kimchi consumption/adult/year is decreasing (36.6 kg in 2018). The amount of commercial Kimchi consumption in 2018 was 757,000 M/T (metric ton), out of 1,892,000 M/T of the estimated total consumption, and the size of Kimchi market was estimated to be 1,398 billion wons. In 2019, 29,628 M/T of Kimchi was exported to 78 countries, and 306,047 M/T was imported, mainly from China. In the future, for the technological upgrading of Kimchi plants, a large capital investment to the production of commercial Kimchi will be required. The accelerated glocalization of Kimchi will bring a steady increase in Kimchi export. Moreover, with the development of global Kimchi culture, the values and images of Korean national brand can be greatly improved.

Kimchi is a traditional food in Korea. It is a fermented food made by several vegetables. Kimchies have traditionally made at home, but the use of commercial Kimchies is increasing. The purpose of this study was to evaluate the intake and evaluation of commercial Kimchies and the perception of desirable learning methods making Kimchies among female high-school students. Three hundred and seventy one female high-school students living in Chonbuk province were participated in the survey. The results obtained were as follows: 1. The percentage of subjects who had consumed commercial Kimchies at least once was 49.7%. It was higher in the subjects living in the rural area(65.6%) than in the urban area(37.9%) at p${\le}$0.001. 2. Positive reasons for the consume of commercial Kimchies was: ‘saving time($4.11{\pm}0.74$)’, ‘convenience to buy when it is needed($4.03{\pm}0.78$)’, ‘variety($3.59{\pm}0.86$)’ and ‘looking good($3.21{\pm}0.98$)’. However, commercial Kimchi received low scores for: ‘sanitation($2.24{\pm}0.96$)’, ‘taste($2.84{\pm}0.96$)’, and ‘economy($2.89{\pm}1.02$)’. 90.5% of the subjects believed that the use of commercial Kimchi will be increased. 3. 24.3% of the subjects had an experience of making Kimchi alone, and 88.7% of the subjects had assisted their mother making Kimchi. 88.9% of the subjects reported that they would like to learn how to make Kimchi from their mothers. 84.0% of the subjects want to make Kimchi by themselves at home when they will be housewives. In conclusion, this report suggests that commercial Kimchi should be produced under more sanitary conditions and Kimchi producers should also develop a variety of tastes to match consumer＇s preferences. There is also a need for education for making high quality Kimchies in school programs of Home Economics. (Korean J of Human Ecology 2(1) : 89-98, 1999)

This study evaluated the physicochemical and microbial quality characteristic of seasonal commercial kimchi for hygienic safety levels. The pH of seasonal commercial kimchi was 3.84-6.36 and the titratable acidity and salinity of the samples were 0.21-1.16 and 1.19-1.54%, respectively. The content of nitrate and nitrite in the commercial kimchi were lower in the spring and summer, which was affected by acidic condition of the kimchi depending on fermentation. Heavy metal contents in commercial kimchi are not an issue because they were detected only at very low levels. The total aerobic bacteria and coliforms counts ranged from 5.25 to 8.44 Log CFU/g and 0.00 to 5.08 Log CFU/g, respectively. The total aerobic bacteria and coliforms were detected more in summer than in the other seasons. E. coli was detected in three of the samples tested. Food-borne pathogens were not detected in any of the samples except for B. cereus. B. cereus was detected in the fall in more than 70% of samples. These results suggest that commercial kimchi distributed in the fall maintain the quality properties and the microbiological safety of kimchi compared to the other seasons. Therefore, further studies as an effective distribution system for the particular seasons will be needed to guarantee the hygienic safety levels of commercial kimchi required by the consumers.

Recently, the consumption of commercial kimchi in Korea has increased over 30% and continues to grow rapidly. Similarly, over 50% of Japanese pickles(Tsukemono) have changed to kimchi and most of them are commerical. The purpose of this research is to cmopare and contrast Korean commerical kimchi to Japanese commerical kimchi. Furthermore, it is to provide valuable information to the consumers and suppliers as well as to improve the quality of commercial kimchi. Five different kinds of materials were used; (A) and (B) kimchi that were made and sold in Korea, (C) and (D) kimchi that were made and sold in Japan, and (E) kimchi made in Korea, but sold in Japan. The kimchi purchased on April 20th, 2002 and sensory evaluation, respectively, and they were preserved at $5^{\circ}C$. For the quality index, the followings contents were measured; moisture, ash, protein, crude lipid, mineral and capsaicin. In addition, pH, acidity and sensory evaluation for kimchi stored at $5^{\circ}C$ were measured for four weeks.
