Introduction. The existing methods of animal fat obtaining have certain disadvantages, hence fat extraction study highly is relevant. Electrochemically activated solutions are known to have a great potential for animal fat extraction. The present paper introduced a new advanced fat obtaining technology based on the principle of electrochemical activation. Study objects and methods. The research featured ostrich fat obtained by wet rendering in water and in an electrochemically activated solution (catholyte) using various processing methods and technological parameters. Standard methods helped define the physical and chemical parameters of the obtained fat samples. Results and discussion. The paper introduced a technological and hardware setup of an ostrich fat production line with the necessary equipment specifications. The research made it possible to define the optimal parameters for fat extraction: the salt concentration for the catholyte = 4 g/100 cm3, voltage = 40–42 V, pH = 11, and redox potential of the catholyte = between –600 and –700 mV. During the fat processing, cell membranes in the electrolyte were destroyed, which inactivated the enzyme system. The obtained combination of physical and chemical factors resulted in ostrich fat of high quality. Fat extraction in an electrochemically activated solution (catholyte) catalyzed the process and increased the fat yield, regardless of the processing temperature. The fat yield exceeded 58% at 55°C and catholyte pH of 11.0. At 95–100°C and pH of 9.5–10.6, it exceeded 95%. Conclusion. The new technology increased the fat yield, maintained its high quality, and reduced the processing cost. Therefore, the developed production line could be recommended for fat extraction of farm animals, depending on the intended use.

“…Food production enterprises, including meat-processing ones are the sources of antropogenic and technogenic impact of its wastewaters on the natural water bodies. Development of technologies for purification and utilization of industrial wastes requires usage of express-tests, which allow one to obtain fast and qualitative characterization of wastes and wastewaters [1][2][3][4][5][6][7][8][9][10][11].…”

Wastewaters of meat-processing enterprise: assessment of genotoxic potential

Environmental pollution and ecosystem dysfunction are one of the most important problems of the today’s world. Assessment of toxigenic properties of effluents from the meat-processing enterprise was carried out using the short-term microorganisms biotests in vitro. Both native waste water and its ether and water fractions were investigated. The probes’ sterilization was carried out by filtration through the sterile membrane filters Synpor with pores diameter of 0.45 m. Mutagenic activity of wastewaters was determined using the Salmonella/microsomes plate with in vitro metabolic activation and without metabolic activation (Ames test). As a metobolic activation the rat liver microsomes were used. Studying of the DNA-damaging activity was carried out using the suspension method modification on the mutant Escherichia coli strains, in which the functioning of one reparation systems is suppressed: uvrA-, recAand рol A-. Native waste water doesn’t have an influence on the mutant strains recAand рol A-, its survivability degree is in the range 96-100%. However, DNA-damaging action was registered for the strain with the damaged excision repair (uvrA-), survivability of which was 81.31%. Ames test of wastewater and its fractions didn’t reveal any mutagenic activity. The tests used in this work allow one to comprehensively estimate the genetic danger of the enterprise wastewaters within a short time and are recommended as test-systems for monitoring the ecological safety of wastewaters.
