  • The study was carried out to evaluate the antimutagenic effects in methanol extracts of Korean soybean paste (doenjang) added with various kinds of water (germanium water, painted maple sap) or salt (sun-dried salt, roasted salt, one time bamboo roasted salt, nine times bamboo roasted salt). Methanol extracts of germanium water doenjang (Ge-D) and painted maple sap (Acer mono Max) doenjang (PM-D) exhibited significant inhibitory activity ($56{\sim}62%$) against aflatoxin $B_1$ ($AFB_1$) by adding of 1 mg/plate in Ames test. Also, methanol extracts of Ge-D and PM-D showed stronger antimutagenic activity toward N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) in SOS chromotest than traditional doenjang (TD). Methanol extracts of doenjang made with four kinds of salt revealed antimutagenic activity toward MNNG; especially, doenjang extracts using one-time bamboo roasted salt (B1-D) showed 94% inhibition at the concentration of 5 mg/plate. Methanol extracts of B1-D also had the strongest inhibitory effect against MNNG of doenjang made with different salts in SOS chromotest. As the results indicate, the various kinds of water and salt have had separate effects on the antimutagenic activity of doenjang; therefore, further research on various physiological functions of water or salt added traditional doenjang is needed.

  • The purpose of this study was to investigate the effect of sea salt on the growth and moisture content of sweet basil, soil moisture content, and salt stress. As a research method, sweet basil was treated with sea salt at 0, 5, 50, 100, and 200 mM concentration of sea salt was investigated to determine the growth and stress time of sweet basil. As a result of the study, it was confirmed that the leaf width increased by 11% when treated with 5 mM, 49% when treated with 50 mM, and 44% when treated with 100 mM. Leaf length was confirmed to grow by 16% at 5 mM, 59% at 50 mM, and 82% at 100 mM treatment. As a future study, based on the effect of sea salt on the leaf and length growth of sweet basil by concentration, it was considered that more research is needed on the beneficial effects of sea salt on edible, medicinal, and aromatic plants. In addition, although salt has only been studied on stress in crops, we intend to contribute to providing basic data for research on ingredients more beneficial to the environment by finding various edible, medicinal, and aromatic plants using the sun-dried salt used in this study.

  • This study investigated the quality changes in cabbage brined with deep sea water salt and in a commercial brined cabbage product. The subject cabbages were separated into two groups: those manufactured in the Lab (ML) and the commercial brined cabbage product (CP). Each group had three brining treatments: with sun-dried salt (S, CS), refined salt (R, CR), and deep sea water salt (D, CD). The salinity level of the ML group was 2.1~2.3%, higher than that of the CP group (1.1~1.5%). The total plate count (TPC) was detected as 5.0 log CFU/g with the S, R, and D treatments at Day 7, but the growth rate of the TPC with the CS, CR, and CD treatments was faster than that with the S, R, and D treatments (6.9~7.7 log CFU/g). A lactic acid bacteria (LAB) level of 5.0~6.6 log CFU/g was also detected in the S, R, and D samples, but only 7.0~7.6 log CFU/g was detected in the CP groups at Day 14. The instrumental hardness levels of the cabbage brined with the deep sea water salts (D and CD) were 3,971 g and 3,932.4 g, respectively, which were significantly higher than those of the samples that were salted with sun-dried salt and refined salt (p<0.05). As for the sensory attributes, S, D, and CD maintained their marketability scores until the end of the storage period for all the properties. CD presented the highest total free amino acid (478.9 mg%), glutamic acid (107.0 mg%), citric acid (428 mg%), and sodium (189 ppm) contents.

  • Before Jin (秦) period, Oriental (Eastern) culture was established in Korea different from China. Bulgogi (babecued beef, 貊炙) and legume fermented soy were transmitted into China. Afterward, alcohol drink, rice cake and cookie, shic-hae (lactic acid fermented fish products), Kimchi (fermented vegetable) were introduced and modified for Korea. Buddhism was transmitted to Korea through China, but selective animal was used as food. Later period of Koryo Dynasty, meat-eating become common due to mongorian influence and distilled spirits was introduced by mongorian. During Chosun Dynasty, table setting of spoon and chopstick was established, due to Confucian influence, dog eating, raw fish and raw meat eating became popular and nutrition for elderly was developed, whereas tea culture declined. In recent period (under the Japanese rule) Chinese introduced chinese noodle, chinese cuisine, chinese pancake and sun-dried salt. many chinese cultivated chinese vegetables.

  • Effects of the kind and concentration of salt on oxidation of lipids and on formation of flavor components have been studied with four varieties of fermented anchovies prepared with 20% sun-dried salt(sample B) , 12% refined salt (sample C), 16.5% refined salt (sample D) and 16. 5% refined salt Plus 25% brine (sample E). The sample B showed higher peroxide and TBA value and also higher content of TMA thar. those prepared with refined salt. The amounts of amino-N and VBN in sample B appeared larger than in sample D but was in a similar level with those in sample C. On the other hands, much smaller amounts of lactic and succinic acid were observed in sample B compared with in sample C and D. Sample C revealed the highest level of lactic acid among the samples tested. The changes in the amounts of each free amino acid displayed similar tendencies in all samples, except decreasing tendency of tyrosine in sample B and increasing tendency of aspartic acid in sample C. Also observed was lower IMP and inosine level in sample B than in C and D, but hypox-anthine level was higher in B. In general, sample I indicated remarkably lower values of experimental data in all cases mentioned above, but the highest TBA balue.

  • The study was carried out to evaluate the anticancer effects in Korean soybean paste(doenjang) added with sun-dried salt(S-D), roasted salt(R-D), bamboo salt roasted once(B1-D) or bamboo salt roasted nine times(B9-D). In MTT assay, S-D, R-D, B1-D and B9-D exhibited a significant inhibitory activity(64-87% and 68-92%) against the proliferation of AGS human gastric adenocarcinoma cells by adding 0.05% and 0.1% of methanol extract. Among Balb/c mice injected with sarcoma-180 cells, the bodies, livers, spleens, kidneys and heart weight of the mice administered with 4 kinds of doenjang extracts were heavier than the non-administered ones of the group. However, no difference was found between the control and doenjang administered groups. Four kinds of doenjang inhibited significantly the tumor growth, especially R-D and B1-D showing an inhibition of tumor cell growth up to 97% by the administration of 1.0 mg/kg methanol extracts of doenjang. The activity of natural killer(NK) cells was relatively high in mice administered with four kinds of doenjang. Particularly, mice administered with R-D methanol extract showed a stronger activity of 88.2%. The activity of glutathione S-transferase(GST) in mice administered with four kinds of doenjang was higher than that of the non-administered group. In particular, the GST activity was the strongest in the group with B1-D. As these results indicate the various kinds of salt have different effects on the anticancer activity of doenjang.

  • This study is on the changing pattern of fish-and-shellfish uses during the last two thirds of Chosun period on the premise that they are influenced by development of fishing technology. With a literary approach, this paper researches how fish-and-shellfish production and consumption pattern changed, especially in relation to technological development of fisheries. First, we examine into the changes of fishery production. And next, we analyze the kind and cooking method of fish-and-shellfish in [Eum-sik-di-mi-bang](1670) and [Gyu-hap-chong-seo](1815). The analysis of two books revealed that there were significant differences in fish-and-shellfish uses. Because the two books were written with a gap of 145 years and the development of fishing technology and remarkable changes of fishery production affected on the fish-and-shellfish uses. Due to primitive fishing tools and skills, fresh-water and reverse-river-fish and shellfish had been caught in substantial amount until the middle ages of Chosun period. As a result, the availability of seafood were limited extremely even in the upper classes. These situations are evidenced by the analysis of [Eum-sik-di-mi-bang]. Only 12 kinds of fish-and-shellfish are described in [Eum-sik-di-mi-bang]. Most of the sesfoods is mollusc which is easy to catch. As for the salt-water fish, dried cod and dried herring were mentioned. Mullet, the reverse-water-fish, is used most frequently. Only one kind of 'Hoe', which needs extreme freshness, is described. This means that the use of fresh fish-and-shellfish was very limited to some kinds which could be caught near the village. As the netting fishery began to be developed in the 18th century, the production of some salt-water fishes, such as anchovy, shrimp, yellow corvina, pollack, and herring, had increased remarkably to make marine resources more available. Small fish, such as anchovy and shrimp were preserved as 'Jeot-gal' and sold nationwide. Therefore, 'Jeot-gal' and seafood could be used in Kimchi around this time and had a deep influence on the change of Kimchi in taste and nutrition. In [Gyu-hap-chong-seo], 33 kinds of fish-and-shellfish are described. Including cod and herring, 17 kinds of sea water fish and mollusc are mentioned. Some of these are consumed in fresh state, neither as dried nor as salted. Because the merchants promoted the transport of seafoods to other regions according to the growth of commercial economy. As a result the diet of the people could be enriched by the various seafoods.

  • We investigated food preservation hurdles used for Korean traditional side dishes. As a first step of the research preparation and cooking recipes of the side dishes were surveyed, which are commonly used in Korean households. As next step, compositional and microbial quality attributes were measured onto the samples collected from the market. Antimicrobial ingredient added in the preparation are reasoned to work as important hurdles based on the scientific principles. Heating processes such as blanching, boiling, braising, hard-boiling and frying help to keep the produce decontamination or water activity adjustment. Measured salt contents of most side dishes were in the range of 1-5% with those of salt-preserved vegetables being higher. pH values were 4.7-6.4 with those of salt-preserved vegetables being lower and those of hard boiled fishes being higher. Soluble solids of braised or hard-boiled dishes were usually above $40^{\circ}Brix$, while those of blanched and seasoned vegetables had lower values. Water activity values were 0.93-0.95 for seasoned vegetables and 0.77-0.88 for hard-boiled or semi dried beans and seafoods. Product with processing steps of braising or blanching showed lower bacterial load of 102-104 cfu/g, while seasoned or salt-preserved vegetables and seafoods had aerobic bacterial count above 106 cfu/g. Korean traditional side dishes were found to apply the appropriate combinations of heating preparation process, water activity and pH adjustment and salting, providing the required preservation properties.
