That ia, it is possible to obtain a shell solution in which the mineral component, v*hich is beneficial for the human body, ie contained at 1.5 weight-percent by dissolving the shells in acetic acid in which citric acid.is contained at 1-3 weight-percent. The mineral components contained in the shells include Na(Natrium), K(Potassium), Ca(Calcium), Pe(Iron), P(Phosphorus), Mg(Magnesium), and the like. In accordance with a further embodiment of the invention, a shell solution is fabricated in which a chitosan acid is contained. The chitosan acid is dissolved into the acetic acid by 5-10 weight-percent. The weight percent of the shell solution and the chitosan acid solution can be selected within a range of 1:99 through 99:1. The present invention is directed to a method of fabricating a shell solution by dissolving -ground shells into acetic acid until the pH of the acetic acid containing citric acid at 1-3 weight percent reaches 6.8 - 7.0. In addition, the present invention is directed to dissolving ground shells into acetic acid, and mixing a chitosan solution into the solution until the pH of the acetic acid containing citric &cid by 1-3 weight percent reaches 6.8 - 7.0. 31 4 0 5 5 The shell solution of the present invention is used as a food cooking liquid, as cooking spices; as a soil conditioning liquid, as a conditioning liquid at various farms, and for other practical purposes. The acetic acid is used because it is eafa as a food. As the acetic acid, artificially-made acetic acid or chemically-made acetic acid may be used. The citric acid contained in the shell solution serves to expedite solution operation of carbonic calcium of the shells. When the citric acid is absorbed in' the human body it also serves to increase absorption of calcium into the body, thereby making it preferable for the shell solution. The embodiments of the present invention will now be described in more detail. Fiypfc Eirifaodjniftrifc In order to fabricate a shell solution according to the present invention, oyster shells are substantially cleaned using fresh water, dried, and ground to a powder. Thereafter, 2 kg of the shell powder is added to 20 1 of the artificially-made acetic acid containing two weight percent of citric acid in a polyamide container, and then stirred using an electrical stirrer having a magnetic bar for about 12 to about 48 hours at a speed of about 150 to about 250 rpm. After stirring, the mixed materials are filtered using a Buchner funnel and a vacuum filter flask connected to an aspirator, thus obtaining the shell solution of the present invention. The remaining shell powder after fabricating the shell solution can be used again. If after 12-48 hours the pH of the 31 4 0 5 5 shell solution is still below 6.8-7.0, the shell solution j.s not 1 * dissolved up to the saturated s£ate. In this case, the dissolution of the shell solution is preferably be repeated until the pH reaches 6.8-7.0. The mineral components provided in the resulting shell solution, which are useful in the human body, are as follows: 1 Components Amount contained 1 Calcium 1.62g/100g Vatrlun 31.4og/100g xalium 16.5ng/10Q« Magnesium 9.70ag/lOOg Phosphorous 9.2oa/100a | Iron 0.34ng/100g 1 Copper O.Ofppa 1 21se O.Mffa I B Manganese 1.75ppe | Second Bmbodimanfc • • The shell solution whioh is fabricated in accordance with the first embodiment of the present invention is diluted by 50-200 times, and when it is used as food conditioner, it is possible to get 600mg of calcium for one person from about 40g of shell solution. 314 0 5 5 That is, the shell solution obtained by the eeeond eabodiment of the present invention can be used as food conditioner for rice, rice cake, noodles, bean-curd, soy-soaked food, salt-soaked fish, grilled fish; jam, soft drinks, food conditioners (such as soy bean paste, soy, spices and condiments, mayonnaise, the like), material for iried food, seasoned soy bean paste, and any other appropriate foods. In a polyamida container, 20 1 of the artificially-made / acetic acid and 1kg of chitosan acid are well mixed. After 48 hours in the container with a lid, a gel-type solution is obtained. 6kg of the above-mentioned gel-type solution is substantially mixed with 12 1 of the shell solution which is obtained by the first embodiment. In addition, if necessary, 2 kg humic acid may be mixed with the thusly mixed solution, thus obtaining a shell solution of this embodiment of the present invention. The humic acid prevents gathering of mold in the artificially-made acetic acid. Thereafter, the shell solution obtained by the second embodiment is diluted with water by 50-200 times. The diluted solution may be used as a soil conditioner, as a liquid for seeds or young plants, as a plant growing conditioner, as artificial food for fish, or for any other appropriate purpose.
