Glycerol and fatty acid influences on the rheological and technological properties of composite films from residues of Cynoscion acoupa

The study was conducted in order to determine how the slaughter age (SA) and muscle type (MT) affect technological properties and fatty acid composition (FAC) of meat among Linda geese reared under the breeder conditions. A total of 16 male geese were slaughtered in order to determine the technological properties and FAC of meat. It was determined that the effect of SA on pH15 and pH24 (TM), water holding capacity (WHC), cooking loss (CL), and drip loss (DL) of the thigh muscle was all statistically significant (P < 0.05). The effect of SA on pH24, WHC, CL, and the 168th-hour DL of pectoral muscle (PM), was statistically significant (P < 0.05). Moreover, the effect of MT on pH15, pH24, WHC, CL and DL in the 12th week and on pH15, pH24, WHC and DL in the 16th week was found to be statistically significant (P < 0.05). Additionally, the effect of SA on monounsaturated fatty acid (ΣMUFA) of TM and polyunsaturated fatty acid (ΣPUFA) of PM and Σω-6 ratios was statistically significant (P < 0.05). Consequently, it was concluded that SA was better in the 12th week than the 16th week and PM was better than TM. The 16-week TM was better in terms of ΣMUFA, the 12-week PM was better in terms of ΣPUFA and Σω-6, and the 12-week TM was better in terms of Σω-3 amount and ω-6/ω-3 ratio. Therefore, it can be recommended that 12-week-old Linda geese be selected in terms of selected meat traits and FAC of meat.

The work is devoted to determining the physical and technological properties of quinoa grain. Quinoa is an unconventional crop for Ukraine, but experiments on its cultivation have been successfully completed in the Sumy region. Due to its unique chemical composition, quinoa is used in dietary and functional products.Quinoa contains about 20% protein, which makes it an excellent dietary supplement for people who do not eat animal products. The amino acid composition of quinoa proteins is very balanced and is characterized by a high content of such essential amino acids. Feature of the fatty acid composition of quinoa. it has a high content of polyunsaturated fatty acids, including linolenic fatty acid and linoleic, which belongs to the acids ω-3 and ω-6 fatty acids.Due to the growing popularity of quinoa and its suitability for cultivation in our climatic and soil conditions, it is important to develop the technology of its storage and processing. One of the main stages of substantiation of the choice of technology for storage and processing of quinoa grain is to determine its physical and technological properties.Physical and technological properties of grain mass are determined by a large number of indicators.Determination of physical and technological properties of quinoa grain was performed for three types of quinoa: red, black and white. In determining the physical and mechanical properties were used methods approved by the relevant standards, or used in research and recommended in the relevant literature.We have identified the following basic physical and technological properties: geometric characteristics, nature, weight of 1000 grains, duty cycle, packing density, air supply, angle of natural slope, coefficient of internal friction, coefficient of external friction. Numerical values of these indicators for each type of quinoa are determined.Knowledge of the physical and technological properties of the grain mass to solve a large number of applied problems that have practical significance. and play an important role in the processes of moistening, heating and cooling of grain. A thorough study of physical and technological properties can provide optimal conditions for storage of seeds without compromising their quality. The obtained data can be used for selection of modes of cleaning, drying and active ventilation.
