The majority of table salts are bay salts and chemical salts. However, chemical salts are known to have a different composition in biological electrolytes and quality of bay salts are getting worse due to the increasing seawater contamination. These facts may have led to the increasing usage of various health-promoting salts. Bamboo salt was introduced in 1986 as a solution to replace table salts to eliminate those detrimental effects, to promote general health and to treat diseases. Although all bamboo salts from different manufacturers have been used for the same health and medical purposes, each manufacturer utilizes different manufacturing process. The ICP analysis was used to study the changes of elemental contents in a bamboo salt during the manufacturing steps as well as these contents in various bamboo salts and other salts. After the first step, contents of Li and Sr in the bamboo salt were increased in comparison with those in the raw material, bay salt. As the next steps continued, contents of K, Ca and Ba were continuously increased. At the completion of the final step, contents of Mg and P were decreased and those of Cu, Mn and Mo were gradually increased. Bamboo salts contained lower contents of Mg, Al, B, and P, but higher contents of K, Ca, Fe, Cu, Mn, Zn, Li, Ba, Sr and Mo than bay salt.

Raw meat of mackerel (Scomber japonicus) was salted by refined, sun-dried, bamboo, and KC1-added bamboo salts. Antimutagenic activity on N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) in Ames test and growth inhibitory effects of AGS human gastric and HT-29 human colon adenocarcinoma cells were investigated using methanol extracts of the salted mackerels. Mackerel salted sun-dried, bamboo, and KC1-added bamboo salts used increased the antimutagenic activities against MNNG, however, the sample treated with refined salt reduced the antimutagenic activity. Inhibitory effects of the salted-mackerels on the growth of human cancer cells were increased as dose dependent pattern. Mackerel salted with refined salt activated the growth of AGS human gastric adenocarcinoma cells, but mackerel salted with sun-dried, bamboo, and KC1-added bamboo salts kept or increased anticancer effect compared to the raw mackerel. Mackerel salted with KC1-added bamboo salt led to the highest antimutagenic and anticancer activities. These results suggest that antimutagenic and anticancer effects of mackerel during manufacturing of the salted-mackerel could be enhanced by using different kind of salts such as bamboo, or KC1-added bamboo salts.

국내산 정제염, 천일염과 죽염(9회)의 pH, 무기질 성분, OH기 함량, 환원력과 DPPH 활성산소 소거 효과를 측정하였다. pH 측정에서 정제염은 약간 산성이고 천일염은 알칼리성을 나타내었고 죽염은 천일염보다 더 높은 알칼리성을 나타내었다. 미네랄 함량은 죽염의 Ca, Fe, Mn, P, S, K 함량이 정제염과 천일염보다 더 많았다. 특히 Fe은 죽염만 함유하고 K의 함량도 다른 소금보다 많이 함유하였다. FT-IR을 이용한 실험에서 OH기 함량도 죽염은 정제염과 천일염보다더 많았고 peak에 따라 정제염은 6.5배, 천일염과는 2.3배의차이가 있었다. Bioanalytical system을 이용한 소금 수용액에서 죽염의 전위 환원력은 정제염과 천일염보다 더 크게 높았다. 1~25% 농도에서 소금의 DPPH 항산화실험에서 죽염의 활성산소 소거 능력이 가장 강하게 나타났고 정제염과 천일염은 농도 증가에 따라 항산화 효과가 큰 차이가 없었다. 25% 고농도에서 정제염과 천일염의 산소 소거 기능이죽염과 16배의 차이가 나타났다. 이상의 결과로부터 죽염은 알칼리성을 띄는 소금이고 OH기 함량과 전위 환원력도 일반소금보다 현저히 높았다. 또한 이들의 화학적인 특성을 가진 죽염은 항산화 효능도 일반소금보다 크게 높았다.

Bamboo salt, a Korean folk medicine, is prepared with solar salt (sea salt) and baked several times at high temperatures in a bamboo case. In this study, we compared the preventive effects of bamboo salt and purified and solar salts on hepatic damage induced by carbon tetrachloride in Sprague-Dawley rats. Compared with purified and solar salts, bamboo salts prevented hepatic damage in rats, as evidenced by significantly reduced serum levels of aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase (P < 0.05). Bamboo salt (baked $9{\times}$) triggered the greatest reduction in these enzyme levels. In addition, it also reduced the levels of the proinflammatory cytokines interleukin (IL)-6, interferon (IFN)-${\gamma}$, and tumor necrosis factor (TNF)-${\alpha}$. Histopathological sections of liver tissue demonstrated the protective effect of bamboo salt, whereas sections from animals treated with the other salt groups showed a greater degree of necrosis. We also performed reverse transcription-polymerase chain reaction and western blot analyses of the inflammation-related genes iNOS, COX-2, TNF-${\alpha}$, and IL-$1{\beta}$ in rat liver tissues. Bamboo salt induced a significant decrease (~80%) in mRNA and protein expression levels of COX-2, iNOS, TNF-${\alpha}$, and IL-$1{\beta}$, compared with the other salts. Thus, we found that baked bamboo salt preparations could prevent $CCl_4$-induced hepatic damage in vivo.

There are several types of salts that classifed into raw salts(Chunil salt, Saeng salt), purified salts (NaCl reagent grade, Hanju salt) and processed salts(Gueun salt, Saeng kum, Bamboo salt) in Korea. Their major element is NaCl but raw salt from sea water contains other minerals such as K, Mg and S. Mineral contents of the various kinds of salt analyzed with ICP-AES and AAS were different, especially on the contents of K, Mg and Ca. Chunil salt was abundant in Ca(1,037ppm), K(3,707ppm), Mg(10,266ppm) and S(7,459ppm), and salt water from the Chunil salt contained small amounts of Pb, Al, Cr and Hg. Processed salts contained high levels of Ca, K, Mg and Fe. Especially, high levels of K, P, Fe and Ge were detected in bamboo salt. Purified salts showed regular crystal form and raw salts exhibited irregular crystal form under the SEM. The processed salts were not crystal form, but fused and irregular round form.

There are several types of salts that can be classified into raw salt(Chunil salt), purified salts(NaCl reagent grade) and processed salts(Bamboo salt, Purple bamboo salt using in this study) in Korea. Salts has been utilized for the food as well as for the drug in the Oriental Medicine. Purple bamboo salt(PB-salt) was made by heating up to 1300℃ nine times after putting the raw salts in the bamboo. Since salt is generally known to cause the blood pressure to elevate, this study was conducted to investigate the effect of PB-salt on an adverse reaction of the blood pressure elevation. The experiment was performed with the 2 protocols ; 1. Effect of NaCl and PB-salt administration i.v. with the different the concentration(250, 500, 750, 1000mg/kg) on a mean artery blood pressure(MAP) change. 2. Effect of 500mg/kg NaCl and PB-salt administration p.o. for 6 days on the systolic blood pressure change. The results were as follows; The results were as follows; In a short minute change of blood pressure by direct method, PB-salt adminstration did not induced the hypertension unlike NaCl adminstration. In a date change of blood pressure by indirect method, systolic blood pressure was increased about 12-18% in the NaCl administration group, whereas within 6% in the PB-salt administration group from 2 days to 5 days. These results suggest that PB-salt might have some unidentified ingredient to be changed in the course of processing, making it superior to other salts.

The objective of this study was to find an appropriate method and process for protecting the green color in bamboo leaves and subsequent extraction of the green colorants, chlorophyll. Various inorganic salts including cupric sulfate, ferric sulfate, and zinc chloride were employed as green color protectors. Accordingly, the effects of metal salts and treatment conditions on color protection were investigated to find appropriate protector and conditions. And also, the efficacy of bamboo colorants as a natural green dye was evaluated through dyeing and colorfastness tests. Antimicrobial activity of dyed fabrics was measured by shake flask method in terms of bacterial reduction rate using Staphylococcus aureus(ATCC 6538). On the basis of experimental results for stabilizing bamboo leaves colorants, it was confirmed that Cu was the most appropriate metal type considering dye uptake, photostability and light fastness, and its optimum concentration was 0.025%. After the stabilization, the colorants were extracted efficiently at NaOH aqueous solution of 1.00%. It was concluded that bamboo leave has a high potentiality as new resources to produce a natural green dye with antimicrobial functionality.

We have developed a new method of manufacturing salts by horizontal spray drying technique, using the concentrated deep ocean water after desalination processes. We studied the chemical characteristics of the spray-dried salts. Sodium content in the spray salts is $28.4\%$, which is $10-30\%$ lower than that of bay salts, bamboo salts and boiling salts $(32-38.2\%)$. However, the contents of magnesium, potassium and calcium of the spray salts are 2.5 times, 3 times and 4.5 times higher relative to those of bay salts, respectively. On the one hand, sulfur content in spray salts is 14 times lower than those of bay salts, which is caused by their volatilization during spray and vaporization of the concentrated seawater. Enrichment factors of Mg (0.8), K (0.9) and Ca (1.0) in the spray salts are relatively higher than those in bay salt (0.2-0.3), bamboo salt (0.15-0.4) and boiled salt (0.4-0.7), respectively. On the contrary, enrichment factor of sulfur in spray salts is observed to be 0.07, which is considerably lower than those in other salts (0.3-0.7). It means that the minerals like Mg, K and Ca can be well conserved from seawater to salts through spray drying techniques, while volatile elements like sulfur, lead, mercury and organic compounds can be easily removed from seawater via spray and heating processes.

Hypertension induces many of the social costs related by cardiovascular diseases. Sodium is known as a crucial factor in inducing type I hypertension. In traditional Korean medicine, bamboo salt (BS) has been used in the attenuation of salts toxic coldness and nowadays it has shown various therapeutic effects. It contains mostly sodium chloride (about 91.7% of BS); however, the effect of BS on hypertension is still not completely understood. Thus, we investigated the effect of BS on blood pressure for the first time. Two group of BS, sun-dried salt (SDS), NaCl, or distilled water (DW, vehicle control) was administrated orally for 8 weeks. Although BS had no effect on body weight and food intake, it increased water intake (p < 0.05). The BS groups, in terms of blood pressure, was similar to the DW group; whereas the SDS and NaCl groups showed significantly increased blood pressure levels (p < 0.05). BS also decreased sodium-chloride cotransporter (NCC) mRNA expression, unlike SDS or NaCl. These observations indicate that BS may be a promising strategy for the prevention of various diseases including salt-related diseases.
