  • The principal objective of this study was to investigate the association of variable salts with the hardness of cubed white radish. We analyzed the contents of domestic sun-dried salt, Chinese sun-dried salt, domestic refined salt, Australian rock salt and Australian industrial sun-dried salt in the radish samples. Our assessment of the water content of variable salts showed that domestic refined salt was highest(7.27%) and Australian rock salt was lowest(0.16%). The NaCl contents of variable salts were as follows : 93.23% in refined salt, 93.76% in Australian rock salt, 87.85% in domestic Shinan sun-dried salt and 87.98% in Chinese sun-dried salt. The content of insoluble matter in water were $0.03{\sim}0.05%$ in all salts except 0.85% in Australian industrial sun-dried salt. The pH values of salts were as follows : 8.93 in domestic sun-dried salt, 8.62 in Chinese sun-dried salt, 6.69 in refined salt, 5.83 in Australian rock salt and 6.41 in Australian industrial sun-dried salt. Regarding the mineral component content assays, domestic salt was found to harbor lower Na content but far higher Mg, K, Ca contents than other salts. In our evaluation of the hardness of cubed white radish, we detected a continuous increase in the hardness of cubed white radish soaking in a 4% salt solution of domestic Shinan natural salt, but an initial increase followed by a decrease in the hardness of cubed white radish soaking in a 4% solution of the other salts.

  • This study was conducted to investigate the quality characteristics of sun-dried salt prepared with added Cheongyang hot pepper juice(CPJ). The moisture, crude protein, crude lipid, and crude ash contents of the CPJ were 84.36%, 2.27%, 1.41%, and 0.67% respectively. The moisture content, yellowness, capsaicin, and dihydrocapsaicin of sun-dried salt increased according to the level of added CPJ, whereas the NaCl, pH, lightness, and redness value increased. The sensory evaluation results showed that preferences for the sun-dried salt increased as CPJ, approached their optimum value and decreased as they exceeded optimum levels. Consequently, the proposed optimum level in the ingredient formulation for manufacture of the standard sun-dried salt was 30% CPJ, as based on analyses. Ultimately, this study was expected to contribute to the commercialization of sun-dried salt of high quality.

  • The feasibility of reduction of sodium intake using sun-dried salt and monosodium glutamate (MSG) was studied. Preference test was performed to evaluate the sensory properties of bean-sprout soup and vegetable rice porridge soup. Sun-dried salt and MSG might be a partial substitute for refined salt. There was a significant difference in salt taste strength between sun-dried salt and refined salt. Sun-dried salts 0.45% with MSG 0.07% resulted in the highest taste preference compared to that of sun-dried salts 0.60% without MSG in bean-sprout soup, which resulted in 23.9% reduction of sodium intake. Sun-dried salts 0.38% with MSG 0.04% resulted in the highest taste preference compared to sun-dried salts 0.53% without MSG in vegetable rice porridge soup, which resulted in 25.4% reduction of sodium intake. There seemed to be a synergistic effect on reduced usage of sodium salt when MSG was used in vegetable rice porridge and bean-sprout soup with 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 $1,400^{\circ}C$.

  • Physiochemical and sensory properties of muskmelon pickles were investigated under salting condition using deep seawater salt, sun-dried salt and purified salt. The changes of weight, shrinkage rate salinity and pH of muskmelon during salting time were almost nothing shown. Turbidity of pickle juice was the highest in salt solution using sun-dried salt and was almost nothing shown in deep seawater salt and purified salt. Solid content of pickle juice was higher in pickle juice using sun-dried salt than deep seawater salt and purified salt. The calcium content of muskmelon salted by deep seawater salt and sun-dried salt were increased to 4.3 times and 3.7 times, respectively. Hardness became a little higher on muskmelon using deed seawater salt ann sun dried salt than purified salt. In organoleptic result, color, flavor, taste, texture and overall palatability of muskmelon salted by deep seawater salt became higher in other salt solution (sun-friend salt and purified salt).

  • Objectives : The purpose of this study was to demonstrate the effectiveness and availability of salt pharmacopuncture of Korean sun-dried salt and processing salt on the basis of bibliographical review. Methods : This study was done through a narrative review of related bibliography including medical books, journals, general bibliography, and web sites. Results : 1. Korean sun-dried salt is produced in the ground with soil, tiles, and pottery. Sun-dried, traditional, granulated, bamboo, and grilled salts are all appropriate for medical use. They are composed of a lower level of NaCl and unnecessary substances, and have a higher water and mineral content. 2. The 9~30 g of NaCl included in the physiological saline matches the ratio of a normal human body. However, if the saline is used for water supply, it should be improved because the recommended amount is much lower. 3. Medicine that includes NaCl is applied for lessening the congestion of the nasal cavity, alleviating cornea swelling, or for a lack of water. NaCl can also be used for washing contact lenses as well as cleaning the mucous membrane of the eyes and nose. 4. Salt relieves anger, detoxifies, induces vomiting, builds strong muscles and bones, gives energy, slows aging, and ultimately improves health. 5. Salt treats many diseases including: cardiovascular, hematosis, respirometer, obstetric, musculoskeletal, mineral supplement, eye, teeth and skin issues, etc.. However, salt is not used for treating asthma, cough, or other ailments mainly affecting the vascular system. 6. While NaCl in salt absorbs water and the vascular constriction results in higher blood pressure, the pressure induced from salt is actually a physiologically temporary rise. Rather, salt helps remove oil from the body and its potassium lowers blood pressure. Conclusions : It was suggested that salt pharmacopuncture of Korean sun-dried salt and processing salt should be made available for adjusting the physiological salt concentration and control of the Na side effects, therefore it would be useful in the treatment of diseases.

  • The objective of this study was to determine the processing conditions for salt dried rockfish Sebastes schlegeli by sun drying and cold-air drying, as measured by alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activity. We processed salt dried rockfish samples. The salinity of rockfish samples was within 1% following salting with 25% salt brine for 3 h. The moisture content of salt dried rockfish was found to reduce linearly from 70.12 to 39.5 g/100 g over the same time interval. The water activities of salt dried rockfish by sun and cold-air drying were 0.94 and 0.87, respectively, after three days of drying. Acid values (AV) were 10.71 and 5.96 mg KOH/g, respectively, after the three day drying period. The ADH activity in a water extract from salt dried rockfish following sun and cold-air drying for 24 h was 228.5% and 226.1% at 13.3 mg/mL, respectively, and was higher than that when drying lasted for 48 and 72 h. The ALDH activity was not affected but both ADH and ALDH activity tended to decrease as the drying time increased from 24 to 72 h. The conditions of processing for the best quality of salt dried rockfish were determined to be drying with a cold-air system for 24 h. These results indicated that water extracts from salt dried rockfish have valuable biological attributes owing to the metabolizing of alcohol and can provide useful information for the design of drying systems for salt dried rockfish.

  • 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.

  • This study examined green tea fermented by the addition of sun-dried salt to increase the extraction of Procyanidins and Gallic acid and Theaflavins. An experiment on the change in the amount of the extract according to the saturation degree of sun-dried salt was performed. The sample of fermented only green tea extracted only Gallic acid (0.004 mg/g). No Procyanidins and Theaflavins were extracted. When the green tea was fermented by sun-dried salt, large amounts of the three compounds were extracted: Procyanidins, 75%(0.244 mg/g) and 100%(0.949 mg/g); Gallic acid, 75%(0.386 mg/g) and 100%(0.691 mg/g), and Theaflavins, 75%(0.083 mg/g). According to the date of fermentation, the largest amount of Procyanidins, Gallic acid and Theaflavins extracted were on the 2nd day(0.295 mg/g) and 7th day(2,256 mg/g) and 4th day(0.168 mg/g), respectively.
