The present study is purposed to suggest accurate guidelines for developing standardized chicken meat stock containing salt, and to develop a product for mass production of uniform quality achieved by applying High Pressure Extraction Cooking(HPEC) using a high.pressure extractor. Through this study, we examined water contents, ash contents, salinity, turbidity and mineral contents of chicken meat stock according to the addition of salt. The ash contents increased with the increase of the addition of salt, but the water contents decreased with the increase of the addition of salt. Salinity increased with the increase of the addition of salt. Turbidity decreased with the increase of the addition of salt, and difference in turbidity according to the addition of salt was regular. Among mineral contents, Na showed the highest content, which was believed to be because of the addition of salt, and it was followed by K and P. The results of this study show that the mineral contents in the stock were different according to the addition of salt, but they were neither proportional to the addition of salt nor showed a regular pattern.

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.

Twenty-three crossbred (Yorkshire $\times$ Duroc $\times$ Hampshire $\times$ Chester White) primiparous sows were used to evaluate the effects of the mineral-salt laxative in lactation diets on sow and litter performance. The sows were fed a sorghum-extruded soybean-based diet with .85% lysine, .90% Ca, .80% P, and 3.2 Mcal ME/kg. Sow body weight (p > .54) and backfat loss (p > .61), average daily feed intake (p > .42), and litter weight gain (p > .74) were not affected by the mineral-salt laxative in the diet. However, survivability of piglets was greater (p < .06) for sows with the mineral-salt laxative in their diet and, thus, number of pigs weaned was increased. As expected, fecal moisture was increased (p < .09) in sows fed the mineral-salt laxative. Apparent digestibilities of DM, N, and GE were not affected by treatment (p > .26). After weaning, stomachs were collected and scored for ulcers and keratinization using a scoring system of 0 = normal to 3 = severe. Severity of ulceration and keratinization was not significantly affected by treatment (row mean scores differ test p > .25), but scores for sows fed the diet containing the mineral-salt laxative were numerically lower than sows fed the control diet. Thus, our data indicate that sows fed the mineral-salt laxative during lactation had improved piglet survivability, greater fecal moisture, and tended to have fewer lesions in the mucosa of the stomach.

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 $1,400^{\circ}C$.

I have conducted two testings to find out which water is better for drinking water. First, I made 20 mM L-DOPA solutions by solving L-DOPA (3,4-Dihydroxyphenylalanine) in tap water, Waters' mineral water and reverse osmotic water. Then I measured activities after adding Tyrosinase (purifide enzyme, step 3), which was extracted from Salanum melongena(mad apple), in each L-DOPA solution. Second, I solved 0.1, 0.5 and 0.9% salt in each 20 mM L-DOPA distilled water to measure activity of each salt solution. The results of the testings are as follows: 1. 10 minutes after adding Salanum melongena(mad apple) tyrosinase in each L-DOPA solution, activity of Waters' mineral water was 0.867 tap water 0.777 and reverse osmotic water 0.742. 2. Activity of Waters' mineral water was higher than that of tap water by 10.4% and higher then reverse osmotic by 14.4%. 3. Activity of Waters' mineral water was much higher than that of 0.9% salt water by 41.8%. 4. The optimum pH of Salanum melongena (mad apple) tyrosinase is 9.0. Most enzymes working in the human metabolism are alkaline and body fluids' pH also alkaline. In conclusion, an alkaline water is believed better than an acidic water for drinking.

Laboratory tests were performed to determine the efficiency of dye solution desalination by electrodialysis. The study involved anionic dye and mineral salt recovery by obtaining two streams from a salt and dye mixture - dye-rich solution and salt solution. A standard anion-exchange and cation-exchange membranes or monovalent selective anion-exchange membranes were used in the ED stack. It was found that the separation efficiency was strongly dependent on the dye molecular weight. The best results for standard ion-exchange membranes were achieved for the desalination of Direct Black solution. Furthermore, the obtained results implied that the application of monovalent selective anion-exchange membranes improved the recovery of dye and salt solutions - the dye concentration in the diluate remained constant irrespective of the molecular weight of anionic dyes, whereas the salt recovery remained very high (99.5%).

Deep ocean water is located in the sea deeper than 200m. At such depth the solar light does not reach, photosynthesis is not performed and nutrition salt is not consumed. Therefore, campared with surface water, Deep Sea Water contains more nutrition salt, such as nitrogen and phosphor. Moreover, it has the good balance of minerals. This Research is primary attempt for apply deep sea water to food industry. New type of mineral salt manufacturing system was developed and high levels of Ca, K, Mg detected from the salt analysis.
