This study was carried out to investigate the effects of refined, solar, and bamboo salt on the physico-chemical properties and sensory characteristics of cured pork loin. Moisture, protein, fat, and ash content, lightness, yellowness, cooking yield, and color, juiciness, and tenderness of sensory properties on curing pork loin exhibited no significant differences regardless of the nature of salts. The pH of raw and cooked cured pork loin with added bamboo salt was higher that of other salt treatments. However, the cooking loss, and Warner-Bratzler shear force of cured pork loin with added refined salt was lower than those of solar and bamboo salt pork loins cured. The flavor and overall acceptability scores of treatments with refined salt was higher than those of solar and bamboo salt treatments. The unique flavor of bamboo salt can render it as a functional material for marinating meat products. In addition, the results of this study reveal potential use of bamboo salt in meat curing.

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.

Bamboo salt has been used as a traditional remedy for gastric ulcer and gastro-intestinal disorders. It is produced by baking the salt packed in bamboo cylinder nine times under the fire of pine tree. Three of commercially available bamboo salt products (bamboo salt A, B, and C) were characterized by qualitative and quantitative analyses using inductively coupled plasma (ICP) spectrometer, ion chromatograph (IC), X-ray diffractometer (XRD), and electron microscope (EM). Compared with crude salt, the contents of iron, silicon, potassium, and phosphate in the bamboo salt products were higher whereas the sulfate content was lower. Water-insoluble fraction of bamboo salts contained the following compounds; MgO, $SiO_2,\;Mg_2Si0_4,\;and\;CaMgSi0_4$. The study on the microscopic structures of the bamboo salts were shown to have smooth surface and fused shape compared with crude salt. Among the three bamboo salt products, product A was used to test a possible inhibitory effect on gastric acid secretion. Each test material (bamboo salt A, crude salt, and reagent-grade NaCl) was given orally to Sprague-Dawley rats at doses of 0.2, 1.0, and 2.0 g/kg for 28 days before pyrolus ligation. Twenty four hours after the last administration of the test materials, volume, pH, total acidity, and pepsin activity of gastric juice were measured by the Shay-ligation method. No significant differences were observed in the secretion of gastric acid between treated groups (bamboo salt-, crude salt- and reagent-grade NaCI-treated groups) and control group (distilled water-treated group). This result demonstrated that bamboo salt did not exert anti-ulcer activities in experimental animals used in the present study.

This study has been carried out to investigate general pharmacological action of bamboo salt (jukyom) in terms of effects on central nervous system and cardiovascular system in experimental animals. After bamboo salt, crude salt or reagent-grade NaCl were orally administered into male ICR mice with dose of 2.0 g/kg, general behavioural syndromes such as body weight and locomotor activity, spontaneous motor activity, pento-barbital-induced sleeping time, muscle incoordination, electroshock-induced convulsion, body temperature and writhing response caused by 0.6% acetic acid solution were observed. Bamboo salt had no influences in these indices for examinition of effect on central nervous system. Additionally, conscious male Sprague Dawley rats fastened overnight won ere treated with bamboo salt, crude salt or reagent-grade NaCl (2.0 g/kg, p.o.) to examine the effect of these salts cardiovascular system. Systolic, median and diastolic food pressure and heart rate were dertemined using tail cuff indirect method. Treatment with Hydralazine (50 mg/kg, p.o) as a positive control produced the decreases in systolic, median and diastolic blood treasure and an increase in heart rate. whereas no changes were observed in bamboo salt, crude salt and reagent-grade NaCl treated groups. These results strongly suggest that bamboo salt may have no effects on general pharmacology of central nervous systems and cardio-vascular systems.

This study was conducted to evaluate the quality characteristics of mugwort-tofu prepared by purified salt (A1), sun-dried salt (A2), bamboo salt (A3), and deep ground water salt (A4) in addition to $CaCl_2$ as coagulants. Addition of various salts with $CaCl_2$ increased yield of the tofu resulting in high content of lipid, protein and mineral contents of mugwort-tofu. Sun-dried salt was most effective in yield of the tofu among tested salts. It was also most efficient in increasing protein, and lipid contents of the tofu. The amounts of Ca, K, Mg, and Na were highest in mugwort-tofu prepared with sun-dried salt, while they were lowest in the tofu with deep ground water salt. The texture analysis showed the tofu prepared with various salts generally increased the hardness and gumminess of the tofu significantly. The sensory evaluation of the tofu with various salts demonstrated that the saltiness, tastiness, chewiness, and overall acceptance were enhanced significantly. Among tested salts, bamboo salt showed the highest overall acceptance in mugwort-tofu, followed by deep ground water salt, purified salt, and sun-dried salt.

The effects of heat treatment on the physicochemical properties and mineral composition of sun-dried salt were investigated. The salts parched at high temperature were appeared the higher alkalinity and the lower oxidation-reduction potential (ORP) than the samples without heat treatment. The commercial salts (bamboo salt and yellow loess salt) and the sun-dried salt parched at high temperature had relatively higher sodium ion content (418-450 ppm) compared to that (418.0 ppm) of refined salt. The increase of calcium ion occurred in the salts parched at high temperature compared to the sun-dried salt without heat treatment, but the magnesium ion was vice versa. The commercial salt, yellow loess salt had highest turbidity (0.973) whereas sun-dried salt showed lowest level (0.097) among the tested samples. Turbidity of heat treatment samples decreased as solubility increased. The maximum concentration of dialyzed salt was reached after 4 hr regardless of various processed salts, but those had no difference significantly among the tested samples. The X-ray diffraction patterns of the parched sun-dried salts showed different peak intensity with common salts, and they were similar to the patterns of oxide salts, especially MgO. The maximum value (2.56%) of MgO appeared in the sun-dried salt parched at $1,400^{\circ}C$.

As(III) and As(V) were analyzed in bamboo salts by hydride generation ICP-AES. In order to quantify the total amount of As in bamboo salts, $AsH_3$ was producted by reacting with 6 mol/L hydrochloric acid and $NaBH_4$, which was then analyzed by hydride generation ICP-AES. As(V) was quantified simultaneously after selectively quantifying As(III). As(III) was quantified by determining the total amount of As and then correcting for the amount of As(III). To improve the reliability of the analysis we repeated the experiment several times to check the detection limit, quantification limit, and measurements of our testing methods. According to the result of our quantification analysis of As existing in bamboo salt, the range of total As content was 0.05 mg/kg~0.2 mg/kg and As(V) was over 90% of the total As.
