The current study was conducted to confirm the anti-cancer effect of Sarijang, which is a mixture of extracts from purple bamboo salt, Rhynchosia nulubilis, garlic, and Ulmi cortex. Nude mice were injected with a human-derived colorectal cancer cell (HCT116 cell line) and subsequently administered Sarijang for 4 weeks, following which the body weight, organ weight, and tumor size were measured. To evaluate the anti-cancer mechanism of Sarijang, the levels of p16 and extracellular signal-regulated kinase (ERK), cell cycle regulators in colorectal cancer, were measured. To evaluate the toxicity of Sarijang on liver and kidney, aspartate transaminase, alanine transaminase, blood urea nitrogen, and creatinine were analyzed. Sarijang not only reduced the tumor size by enhancing p16 and suppressing ERK, but also showed no side-effect in the liver and kidneys. Taken together, Sarijang has the potential to inhibit tumor growth without side effects, and may be used as a useful functional food.

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.

In this study, doenjang samples were prepared with different types of salts (12%, w/w): purified salt (PS), 3-year aged solar salt (SS3), 1-year aged solar salt (SS1), and bamboo salt melted 3 times (BS). Whole-soybean mejus were fermented with starters consisting of 2 Bacillus strains, a yeast, and a fungus (starter doenjang), and control mejus were fermented with organisms present naturally in rice straw (non-starter doenjang). The whole-soybean mejus were dried, and then mixed with cooked soybeans and the respective salts. The doenjang samples were fermented for 13 weeks at 25℃. The protease (acid, neutral, and alkaline) activities, fibrinolytic activities, and antioxidant capacities of the samples were examined every week. BS doenjang showed the highest acid protease (6.46 ± 0.20 unit/g) and fibrinolytic activities (0.61 unit/ml). Among the starter doenjang samples, those made with SS and BS showed the highest total phenolic contents after 91 days of fermentation. For antioxidant activities, SS3 doenjang showed higher activities than the other doenjang samples, as evaluated by ABTS, DPPH, and FRAP assays. These results suggest that solar salt, especially aged for 3 years, is better than purified salt in terms of producing better functionalities of doenjang.

Gochujang, a traditional Korean food, is fermented by mixing red pepper powder, various grain, meju and salt. Changes in the kind of ingredients and fermentation method could increase health functionalities. In this study, in vivo anti-colitis effects of gochujang prepared with mixed grains, bamboo salt baked 3 times and meju starters on DSS-induced colitis in C57BL/6 mice were studied. We prepared gochujang prepared with mixed grains (MG), bamboo salt, and Aspergillus oryzae (A) and Baccillus subtilis (B) mixed starters (MG-AB) and gochujang prepared with MG, bamboo salt and A, B and Lactobacillus plantarum (L) mixed starters (MG-ABL). MG-AB and MG-ABL significantly increased body weight and colon length compared to the control (p<0.05). MG-ABL showed significantly decreased interleukin-6 (IL-6) expression in serum compared to the control and MG-AB group (p<0.05). MG-ABL also regulated mRNA and protein levels of pro-apoptotic Bcl-2-associated X protein (Bax) and anti-apoptotic B-cell lymphoma-2 (Bcl-2) in the mice colon tissue (p<0.05). Therefore, MG-ABL exhibited the increased anticolitis effects by inhibiting damage of colon tissue, probably by regulating a pro-inflammatory cytokine of IL-6 and regulated apoptosis related genes. These results indicated that gochujang changed with good ingredients and starters had colitis preventive effects and might be due to active compounds in mixed grain and bamboo salt, and produced by L during the fermentation of gochujang.

This study was carried out to investigate the effects of various kinds of commercial salts including Chunil, Hanju, Guwoon and Bamboo salts on the growth of microorganisms involved in kimchi fermentation. Among various microorganisms related to the kimchi fermentation, the growth of Leuconostoc mesenteroides, Lactobacillus plantarum, Pichia membranaefaciens and E. coli was examined. Based on the conditions of kimchi fermentation, 3% and 5% concentration of each salt were studied. Also, the temperatures at 1$0^{\circ}C$, 18$^{\circ}C$ and 37$^{\circ}C$ of the cultural condition were examined. The growth of Leuconostoc mesenteroides was inhibited depending on the reduction of cultural temperature and increase of concentration of salts. There was no considerable difference on the growth of Leu. mesenteroides in the different the kind of salts. However, the growth of Lactobacillus plantarum was strongly inhibited by the 5% concentration of Bamboo salt during incubation at 18$^{\circ}C$. When Lactobacillus plantarum was cultured at 1$0^{\circ}C$, its growth was remarkably decreased regardless of the kind and concentration of salts. In the case of Pichia membranaefaciens, Bamboo salt strongly inhibited its growth at all cultural temperatures. Apparent inhibitory effect on the growth of E. coli was observed by the Bamboo salt treatment during the incubation at 18$^{\circ}C$. At the cultural temperature of 1$0^{\circ}C$, similar results obtained.

Saeu (shrimp) jeotgal (SJ) was prepared by mixing with 25% salt with different types: purified salt (PS), solar salt aged for 1 year (SS), and bamboo salt. SJ was fermented for 22 weeks at $15^{\circ}C$. Bacilli and marine bacteria were detected throughout the entire fermentation period, and marine bacteria were present in the largest numbers. Lactic acid bacteria (LAB) were detected only during the first 8-10 weeks, but yeasts appeared at the sixth week and later. Archaea were detected in low numbers only from SS-SJ during the first 8 weeks. BS- SJ showed higher pH and lower titratable acidity (TA) values than other SJs because of strong alkalinity of bamboo salt. Amino-type nitrogen (ANN) contents of SJs increased during fermentation, especially, after 2 and 6 weeks. SS-SJ showed the highest ANN content from the beginning to the end of fermentation. Ammonia-type nitrogen (AMN) contents also increased like the amino-type nitrogen during fermentation. The highest volatile basic nitrogen (VBN) was also observed in SS-SJ. Salinity was kept constant after 4 weeks. SS was better than other salts for SJ fermentation in terms of protein hydrolysis.

Samples of doenjang (a fermented soybean paste) were prepared with different types of salts; purified salt (PS), 3-year-aged solar salt (SS3), 1-year-aged solar salt (SS1), and bamboo salt (BS, 3^rd processing product). For starter doenjang samples, selected starters comprising two bacilli, one yeast, and one fungus were inoculated, whereas for non-starter doenjang samples, microorganisms present in rice straw were inoculated after enrichment. The doenjang samples were fermented for 13 weeks at 25℃. During the fermentation period, SS and BS doenjang samples showed higher bacilli counts as well as much lower yeast counts than PS doenjang. At 13 weeks, yeast counts of starter doenjang samples were 7.75, 5.69, 6.08, and 4.74 log CFU/g for PS, SS3, SS1, and BS doenjang, respectively. For non-starter doenjang samples, counts were 7.17, 5.05, 5.92, and 4.54 log CFU/g for PS, SS3, SS1, and BS doenjang, respectively. SS and BS promoted growth of bacilli but inhibited growth of yeasts compared with PS. Debaryomyces hansenii was the dominant yeast in PS doenjang, whereas Candida guilliermondii and Pichia sorbitophila were dominant in SS and BS doenjang. In the sensory evaluation, SS and BS doenjang scored better than PS doenjang. In conclusion, SS and BS seem better than PS for production of high-quality doenjang.
