РОЗРОБКА ЕНЕРГОЕФЕКТИВНОЇ ТЕХНОЛОГІЇ УТИЛІЗАЦІЇ ВІДХОДІВ ОЛІЙНО-ЖИРОВОЇ ГАЛУЗІ

Modern technologies of production of oilseed fat products involve filtration using viable clays. Depending on the technology, 12-15 kg of bleaching clay are used per 1 ton of vegetable oil. Every year, about 80 tons of waste clay accumulates at the oil refinery with a capacity of 100 tons / day of oil. Depending on the technological process, the oil content in the bleaching clays after their mining can reach 65%. This sorbent is used once, so it is accumulated in large quantities at combines as a by-product. This material is classified as hazard class IV for its self-ignition ability. Therefore, the issue of solving the problem of its utilization is relevant. And biotechnological processing of these wastes into useful products is the most expedient and effective in terms of energy-efficient, ecological and economic requirements. The article deals with the state of the Ukrainian market, the classification of waste of the oil and fat industry, the directions of low-waste and non-waste technologies. The biotechnological potential of microbial lipases is shown, perspective and expediency of application of biotechnological method of utilization of fat fraction of waste using enzyme preparations. The conditions of fermentolysis of the waste of hydrogenated fat and margarine production of Rhizopus japonicus lipase, in particular its thermal stability, are considered. The obtained results of the study indicate the prospect of hydrolysis with Rhizopus lipase. It has been established that the content of free fatty acids in the hydrolyzate reaches the level of saturation after 72 hours of enzymatic hydrolysis, and the concentration of triglycerides is reduced to a minimum value. The thermal stability of lipase Rhizopus japonicus reaches a maximum at 40 ° C. The results of research should be used to improve the technology of processing waste oil and fat industry food and processing industries. [ABSTRACT FROM AUTHOR]
