Технологія комплексної переробки жирної коріандрової олії

Abstract

Thesis for a candidate degree of technical sciences by specialty 05.18.06 − fats, essential oils and perfume-cosmetic products technology. − National Technical University “Kharkov Polytechnic Institute” Ministry of Education and Science of Ukraine, Kharkov, 2016. The thesis is devoted to scientific substantiation and development of technology of complex processing of oily Coriander oil. Physical and chemical properties and fatty acid composition of industrial designs primary oil have been determinated. The study established effective technological options to reduce acid and peroxide numbers oil by extraction refining. Effective technological parameters of carrying out of enzymatic esterification of oil with processing anion has been discovered; as a result of that we received product with high physiological value by the content of ethyl esters of fatty acids. According to analytical and experimental studies rational conditions of fractional crystallization of greasy Coriander oil have been defined. The study shows mathematical models of dependence of output target fraction of oil and its melting point from main parameters of fraction of refined oil. Physical and chemical, medical and biological characteristics of fatty and acid composition of samples refined oil have been defined. It proved that it meets the requirements of the food. On the basis of the experimental research was developed technological scheme of complex processing fatty oils Coriander, including extraction refining and fractional crystallization. It was found that through the use of new technology may get two products - "Petrozelin Coriander" and oil of Coriander for salad. Technological properties of these products were defined that allow their use in recipes of baked goods.
