  • This study was carried out to investigate the effects of various salts on the physical and fermentative characteristics of doughs and on the quality of white pan breads produced using purified salt, Korean solar salt, Chinese solar salt, Mexican solar salt, washed and dehydrated salt, roasted salt, and bamboo salt. In farinogram patterns, dough prepared using the purified salt had the highest water absorption. Extensograms showed that the resistances and resistance/extensibility ratios of the doughs with the solar salts were higher than those with the purified salt. In amylograms, the dough with the bamboo salt had the highest viscosity value. A specific volume was the smallest in the bread with the Korean solar salt (4.11 mL/g), while the largest with the Mexican solar salt (4.85 mL/g). A baking loss rate of the bread prepared with the Korean solar salt (10.34%) was less compared to other samples (10.91 $\sim$ 11.65%). The crust of the bread added with the Korean solar salt showed higher L value and lower a value while its crumb showed the highest b value. A sensory evaluation indicated that significant differences in some characteristics of the breads were observed in the breads prepared with the Korean solar salt and Mexican solar salt. However, flavor, taste, and overall acceptability showed no significant differences among all breads prepared with different salts.

  • The effects of Korean solar salt on an azoxymethane (AOM)/dextran sodium sulfate (DSS)-induced colon cancer C57BL/6 mouse model were studied. Korean solar salt samples (SS-S, solar salt from S salt field; SS-Yb, solar salt from Yb salt field), nine-time-baked bamboo salt (BS-9x, made from SS-Yb), purified salt (PS), and SS-G (solar salt from $Gu\acute{e}rande$, France) were orally administered at a concentration of 1% during AOM/DSS colon cancer induction, and compared for their protective effects during colon carcinogenesis in C57BL/6 mice. SS-S and SS-Yb suppressed colon length shortening and tumor counts in mouse colons. Histological evaluation by hematoxylin and eosin staining also revealed suppression of tumorigenesis by SS-S. Conversely, PS and SS-G did not show a similar suppressive efficacy as Korean solar salt. SS-S and SS-Yb promoted colon mRNA expression of an apoptosis-related factor and cell-cycle-related gene and suppressed pro-inflammatory factor. SS-Yb baked into BS-9x further promoted these anti-carcinogenic efficacies. Taken together, the results indicate that Korean solar salt, especially SS-S and SS-Yb, exhibited anti-cancer activity by modulating apoptosis- and inflammation-related gene expression during colon carcinogenesis in mice, and bamboo salt baked from SS-Yb showed enhanced anti-cancer functionality.

  • This study was conducted to evaluate the heavy metal contents of mudflat solar salt, salt water, and sea water produced in the nationwide salt pan. In mudflat solar salt, moisture contents were significantly different (p<0.001) between regions, ranging from 7.357% to 14.862%. Arsenic (As) content ranged from 0.007 ppm to 0.497 ppm, cadmium (Cd) from 0.000 ppm to 0.101 ppm, plumbum (Pb) from 0.000 ppm to 0.191 ppm, hydrargyrum (Hg) from 0.006 ppb to 0.180 ppb, and copper (Cu) from 0.039 ppm to 4.794 ppm between regions, which were significantly different (p<0.001). Further, As, Cd, Pb, and Hg contents of sea and salt water were not in excess of their criterion points. Our results suggest that heavy metal contents of mudflat solar salt, salt water, and sea water produced in the nationwide salt pan were at safe levels. However, continuous management of heavy metal contamination, such as PVC met, is still necessary.

  • In this research, the concept of a salt farm parallel solar power system, which produce salt and electricity at the same site, is proposed for the first time in the world. The concept is that large waterproof plates made by interconnected solar modules are installed at the bottom of the salt farm. The pilot system was successfully installed at a sea shore, and verified its feasibility as a solar power plant. For deeper understanding, simulations for power prediction of the system were carried out and compared with the field test results. The power generation of the salt farm parallel system is comparable to conventional solar power plants. The cooling effect by sea water contributes more to the increase in the crystalline silicon photovoltaic module performance than the absorption loss due to sea water by maintaining certain height above the module.

  • The antioxidant effects of chungkukjang, a popular fermented soybean paste in Korea, prepared with solar salt were investigated in vitro. DJI chungkukjang(DJIC) was prepared using 3%(w/w) solar salt or 3%(w/w) refined salt, and fermented by Bacillus subtilis DJI. All of DJIC with no salt, DJIC with 3%(w/w) solar salt, DJIC containing 3%(w/w) refined salt, and commercial chungkukjang were extracted with ethanol, hexane, and water. Antioxidative activities were measured by 1,1-diphenyl-2-picryl hydrazyl(DPPH) free-radical generation, nitrite scavenging activity, peroxide value in the presence of linoleic acid, and the Rancimat test, in comparison with the commercial antioxidant butylated hydroxytoluene(BHT). Ethanol chungkukjang extracts showed the highest antioxdative capacities, whereas DPPH free-radical generation and scavenging activities, and linoleic acid peroxide values of DJIC extracts prepared using solar salt, and salt-free DJIC, showed the greatest values. In addition, extracts of DJIC prepared using solar salt had the highest antioxidant indices. Antioxidative activities were higher in DJIC extracts than in those of commercial chungkukjang. However, the antioxidative capacities of DJIC prepared using solar salt and DJIC with no added salt were less than those of BHT. In conclusion, these results suggest that extracts of chungkukjang prepared using solar salt are useful nutritional antioxidants and that dietary supplementation with such materials would decrease oxidative stress.

  • Salt is a major component in salt-fermented shrimp with 25% content. There are various types of salts that have different compositions, which may affect the quality of salt-fermented shrimp. We have investigated effects of various salts such as Korean solar salt (KSS), purified salt (PS), sea-concentrated salt (SCS), glasswort (Salicornia herbacea L.) spray solar salt (GSS), glasswort-sea-concentrated salt (GSCS) and spray-dried salt (SDS) on the physicochemical and sensory properties of fermented shrimps. Ammonia nitrogen content of the salted shrimp prepared with SDS was lower than others until 60 day fermentation. At 90 day fermentation, amino nitrogen contents of salted shrimps prepared with GSCS and GSS (980 mg%) were higher than those of the others while sample prepared with SDS showed the lowest amino nitrogen content (680 mg%). Volatile basic nitrogen content of salted shrimp prepared with SDS was also lower than those of the others between 14 and 60 day fermentation and there were differences among samples in the contents of trimethylamine at 180 day fermentation. Sensory evaluation results indicated significant differences in salty, overall taste and overall acceptance among samples. Overall acceptance was significantly higher in salt-fermented shrimp prepared with KSS, SCS, GSS, GSCS and SDS than in fermented shrimp with PS.
