Nutsubidze Study of the Soybean Protein Amino Acid Composition and Preparation of High Nutritional



	Value Food Protein Product Presented May 28, 2002 Abstract. Georgian varieties of soybean: Kartuli-7, Kolkhuri and the variety Armaviri taken for comparison, distinguished by high protein content were studied. The amino acid composition of combined preparation of albumins and globulins isolated from the defatted flour of each variety has been defined. In the studied varieties the total content of the main indispensable amino acids is rather high. At the same time it should be noted that high content of methionine conditions high level of sulphur-containing amino acids in the varieties studied. Based on this, the method of obtaining of valuable food protein containing selected albumins and globulins, which is different from traditional method of soybean protein product preparation, has been elaborated. The obtained porous product is characterized by high content of indispensable amino acids as well as methionine and thus has high nutritional value. The elaborated method of preparation of high nutritional value food protein from soybean is cost-effective and permits to avoid extra expenses needed for production of texturized soybean protein product. Key words: soybean, amino acid composition, food protein. Biochemistry M. Garuchava, Kh. Kakhniashvili, K. Bezhanishvili Huminic Acids in the Process of Sorption of 2,4-D Herbicide with Chernozems of Eastern Georgia Presented by Member of the Academy G. Kvesitadze, December 24, 2002 Abstract. Sorption of herbicide 2,4-D and ammonium salts with chernozems of East Georgia has been studied. Herbicide 2,4-D and its salts are mostly sorbed on the surface of mineral particles. Kaolin minerals are characterized by high adsorption active centres of which are Al³⁺ and Fe³⁺. The role of huminic acids, in the process of sorption of herbicide 2,4-D is defined. They cover the mineral part of the soil with a thin layer, therefore herbicide is accessable for soil microorganisms due to which it easily undergoes metabolizm. Its biotransformation products are less permeable by the roots to the plant, which causes the accumulation of 2,4-D and its biotransformation products in the soil for a long time. Key words: herbicide, himinic acid, minerals, adsorption, chernozem. Zoology M. Murvanidze, G. Weigmann, Kh.
