The Aim of the study: The determination of the new approach to extraction of the components from mainly protein-, fat- or starchcontaining plants to obtain high-quality liquid and paste-type food substances and their components (the protein concentrates, decolorized and deodorized vegoils), without preliminary defatting of soybeans, multistep preliminary processing of raw materials, without high-temperature treatment and large amounts of solid or liquid wastage. The Methods of the investigations and equipment: colorimetrical, spectroscopic, flame-photometrical, titrimetrical, adsorptive gravimetrical and some biochemical methods; the centrifuges, dispersants, shakers, micro pumps, adsorptive columns, thermostat, desiccators, adsorptive gravimetrical unit. Received results and novelty: The possibility of extraction more than 85 % soybeans proteins and nearly 100 % - from oath and peas without preliminary defatting, heating and fine grinding (in contrast to well- known and commonly used ways of pretreating vegetable raw materials), was found. The conditions of the processing the soybeans with 0,25-6,0 % alkaline solutions within 1- 24 hours at room temperature were defined. It gives the possibility to extract all proteins into liquid phase or leave them paste-like. The compositions of the solutions of electrolytes, as well as ratio between these solutions and vegoil for practically complete removing of free fat acids, traces of proteins and wax-like substances and removing 70-80 % of colorizing and odorizing compounds from vegoils by one - step procedure without heating and with minimizing the volumes of washing water and wastage were determined. The possibility to obtain carbon adsorbents prepared from agrowaste using "thermal strike" procedure was established. The samples of carbon adsorbents with high adsorbability of the dissolved compounds were produced from farm waste by carbonization and activation in that kind of treatment. Efficiency: the increase of extractability of the proteins of fullfat soybeans by water solutions by 10 - 15 %; significant simplification of the alkaline fining of vegetable oils, adsorptive decolorizing and deodorizing of the vegoils, farm production waste utilization. Area of the utilization: Plants of food industry. Product Description popup.authors popup.nrat_date 2020-04-02 Close
