The nutritional value of kimchi is gaining global focus along with new possibilities and uses for the various salts used in making kimchi. The purpose of the study is to conduct research on the uses of various salts and investigate the consumer recognition of salt use in kimchi preparation. The findings are from 824 consumers over 19 years old from 15 locations who participated in this questionnaire via one-to-one interviews from September 23rd to October 14th, 2009. The results of the questionnaire show that when customers cooked, 71.9% used solar salt, 62.2% used flower salt (refined salt), 27.4% used Hanju salt (purified salt), 59.0% used processed salt (roasted salt), 47.4% used bamboo salt, 69.4% used Mat salt (table salt), and 18.2% used low sodium salt. The most preferred origin of salts was domestic. Most customers salted Chinese cabbage while preparing kimchi. Consumers showed low perceptions of different salts used in kimchi production, and did not exactly recognize the characteristics of various salts. The preferences for domestic and solar salts were very high, while the preference for sea salts was low. In conclusion, various types of salts could improve the quality of kimchi. This study hopes to help consumers produce better kimchi to match different needs. Therefore, attention should be paid to promoting the characteristics of various salts influencing the quality of kimchi.

Calcium lactate has been known extending shelf-life of several lactic acid fermented foods through buffer action with lactic acid and binding of calcium and pectic polysaccharides in the tissue. But, the effects in kimchi during storage and distribution has not been observed. Calcium lactate is tasteless, nontoxic compounds commonly used in a number of food products. Recent observations have indicated the potential usefulness of calcium lactate as food additive which has anticariogenic-, antimicrobial-, anticalculus, anti- carcinogenic effects and enhancement of bone mineral density. In this work we determined the effects of calcium lactate(CaL)-treatment(0, 1, 2 and 3% against salted Chinese cabbage) on the pH, acidity, microbial counts, content of alcohol insoluble substance and calcium texture, color, scanning electron microscopic observation of kimchi tissue and sensory test during storage. pH of CaL treated kimchi were higher(3.78∼3.92) than that of control products(3.58). Total microbe(TM) of CaL treated kimchis were lower but ratio of lactic acid bacteria against TM was higher than those of control products, respectively. Calcium content of treated products were 3-5 times higher than control products. The hardness and crispy taste of treated products were remarkably higher than those of control products evaluated by SEM observation AIS analysis, sensory and textural analysis. Moreover, evaluation on the pH, acidity and sensory test showed the shelf-life of treated kimchi(CaL 2%) to be 25-30 days, which was 13-15 days longer than that of control products.

Grapefruit seed extract powder (GFSEP), which was made with grapefruit seed extract and calcium carbonate, was investigated to retard the fermentation rate. The mixing ratios of GFSEP to salted Chinese cabbage were 0.1, 0.3 and 0.5％. Quality characteristics of kimchi such as pH, titratable acidity, reducing sugar content and microbial loads were measured during fermentation at 10$^{\circ}C$. pH and reducing sugar content of control and kimchi sample with 0.1％ GFSEP showed decreases until 10 days, and then attained to stabilized levels. Kimchi samples with 0.3％ and 0.5％ GFSEP maintained a higher pH and reducing sugar content, while microbial load was lower than others. Based on the pH and tit ratable acidity, kimchi samples with GFSEP prolong the shelf life about 3～10 days.

The studies were carried out to investigative effects of Lithospermum erythrorhizon, Glycyrrhiza uralensis 3% (LG) with and without dipping of salted Chinese cabbage in 1% chitosan solution(LGDC) on fermentation of kimchi at $10^{\circ}C$ during 25 days. The pH and titratable acidity of kimchi with LG and LGDC were higher and lower, respectively, than that of control. Viable cells of total bacteria, lactic acid bacteria, Leuconostoc sp. and Lactobacillus plantarum in kimchi added with LG and LGDC were shown inhibitory effect about $1.6{\sim}2.1,\;1.2{\sim}2.9,\;0.8{\sim}2.2,\;0.7{\sim}1.6$ log10 cycle, respectively. Specially Leuconostoc sp. and L. plantarum was very inhibited than in control from 0 day. The sour taste of LG and LGDC added kimchi was changed more slowly than that of control during fermentation of kimchi. But flavor, color and overall acceptability did not show significant difference(P<0.05) between treatments. The shelf-life of LGDC added kimchi was extended over 10 days compared with control.

Xanthan gum (XG) was investigated for use as a thickening and stabilizing agent in kimchi during fermentation at 10$\^{C}$. The mixing ratios of XG to salted Chinese cabbage were 0.1, 0.3 and 0.5%. Quality characteristics of kimchi such as pH, titratable acidity, reducing sugar content and microbial loads were measured. pH and reducing sugar content showed abrupt decreases after 5 day lag time until 20 days, while titratable acidity steadily increased during fermentation. The addition with 0.5% XG retarded the change rates of pH and titratable acidity showing the slowest change. Kimchi samples added with 0.1% and 0.3% XG maintained a higher reducing sugar content during the whole fermentation period of 30 days. Microbial loads showed an abrupt increase from 5 to 10 days, and maintained a nearly same load thereafter. Kimchi sample added with 0.3% XG showed better scores in color, aroma and taste.

The waste brine gained from successively reused brine during kimchi manufacturing can cause serious water pollution. We investigated the filtration effects on the physicochemical characteristics and microbial counts of the waste brine. Chinese cabbage was salted for five times successively, and the waste brines were filtered through sand and active carbon column. While original values of salinity and soluble solid contents of waste brine were 15.4% and $18.0^{\circ}$Brix$, respectively, we observed decrease of them to 0.1% and $0.0^{\circ}$Brix$, respectively, after filtration of the waste brine through sand followed by active carbon column. The filtration also recover pH value of the waste brine to its original value, which was decreased by successive salting from 8.3 to 6.0. We also observed that COD of waste brine increased to 63.2 ppm after five times of salting but decreased to 5.1 ppm after active carbon filtration. Total viable count was also increased with successive 5 steps of salting and was not detected after active carbon-filtration.

This study examined the changes of side dishes in "Eumsikdimibang", "Gyuhapchongseo", "Chosunmusangsinsikyorijebub" over time. As food ingredients, seaweed, red pepper, salted fish, Korean hot pepper paste have been used in "Gyuhapchongseo". The use of cattle by parts, saltwater fish, Chinese cabbage, powdered red pepper, garlic have increased in"Chosunmusangsinsikyorijebub". Cooking techniques, such as the use of wheat flour, a double boiler by the use of steam, and boiling and then roasting cuisine were mostly used in"Eumsikdimibang", but reduced in"Gyuhapchongseo". In "Gyuhapchongseo", the cooking methods are primarily aimed at a positive visual effect, and slices of dried meat seasoned with spices have increased. In"Chosunmusangsinsikyorijebub", various Tang (Guk), the taste of food changed by controlling the gravy content (Gigimi, Chigye, Chorim), meat mixing oil, vegetable and mushroom together to cook and boiling down the main food ingredients to soak the seasoning were increased. Dog-meat steamed dish using the intestine of dog in "Eumsikdimibang" was changed to small intestine of cattle steamed dish in "Gyuhapchongseo". And seasoned dog meat with choncho in "Eumsikdimibang" influenced on beef tail soup with Korean hot pepper paste in "Gyuhapchongseo", and Yookgyejang soup using Korean hot pepper paste in"Chosunmusangsinsikyorijebub". In steamed young chicken, the stuffing such as soybean paste, choncho, welsh onion, leek and flour in "Eumsikdimibang" was changed to minced beef, welsh onion, dropwort and Shiitake mushroom in"Gyuhapchongseo". The steamed young chicken in "Chosunmusangsinsikyorijebub" with stuffing was added to chicken soup using glutinous rice, and ginseng powder. Now, the chicken soup was changed to Samgyetang with glutinous rice, and ginseng. In "Chosunmusangsinsikyorijebub", various vegetable dishes were cooked with beef.

"Banchandeungsok" is recipe book written by a woman from a noble family who lived in Cheongju during the late 1900s. The book has 9 among 46 Kimchi recipes. In this study, the literatures from 1700 to 1900s, "Jeungbosanlimkyeongje", "Gyuhapchongseo", "Siuijeonseo", "Buinpilji", "Bogamrok", and "Josenmussangsinsikyorijebeob" were reviewed to examine the significance of "Banchandeungsok" Kimchi in the aspect of food culture. The results are as follows. "Banchandeungsok" Kimchies were considered as typical type of Kimchi of the late Joseon, and the main ingredients include Chinese cabbage, white radish, and cucumber. Salted-fish juice was not used for making Mukimchi, Bachujjanji, Jjanji in "Banchandeungsok", and gallic, ginger, green onion were used as main spice. Therefore, "Banchandeungsok" Kimchies belongs to Damjeo (light salting) type, which is characterized by light and clear flavor of present Cheongju Kimchi. While salted-fish juice was not used for "Banchandeungsok" Kimchies, yellow corbina was used in the most of "Banchandeungsok" Kimchies. Various forms of pepper were used in "Banchandeungsok" Kimchies - green pepper, peper leaf, minced, sliced shredded and powdered red pepper. Two kinds of Kkakdugi were introduced in "Banchandeungsok", which is the first record in the literatures. A typical type of stuffed cucumber pickles and unique type of cucumber Kimchi appeared in "Banchandeungsok".

This study was conducted to investigate the fermentation characteristics of kimchi treated with different methods of water extracts of powdered green tea(GT). Four different kimchis, the SB-kimchi(control) which was not treatment of the extracts, SG-kimchi prepared with Chinese cabbage(CC) salted in 1％ GT containing 10％ brine, DG-kimchi prepared with CC dipped in 1％ GT for 30 min after salting, MS-kimchi prepared with the salted CC mixed with 1％ GT containing seasonings. All kimchis was fermented at 10$^{\circ}C$. The pH of treated-kimchis were maintained higher than those of control products during fermentation, but it showed no big difference between each treated groups. Total microbe of SB-kimchi(6.27-9.37 cfu/mL) was higher than those of GT-treated kimchi(5.17-9.20) during fermentation. The ratio of lactic acid bacteria against total microbe was higher than the treated kimchis. Total polyphenol content of kimchi was 52.75 mg％ in DG-kimchi, 47.71 mg％ in MS-kimchi, 44.89 mg％ in SG-kimchi, 30.70 mg％ in SB-kimchi on the 5th days of fermentation. Scores of crispy taste of SG- and DG-kimchi on the 5th days of fermentation was 4.03 and 4.01 points, respectively which was higher than control products. Scores of fishy and hot taste of GT-treated kimchi were lower than those of control products during all fermentation periods.
