Physicochemical and biochemical changes may occur in products of animal origin under the influence of internal and external factors, depending on the storage conditions. For the products made from the meat raw materials of various origins, it is important to know the optimal duration and modes of storage, which will preserve the optimal indicators of product quality and safety. The study aimed to determine the effect of different temperature regimes during storage on the quality and safety indicators of canned quail meat. Three series of experiments were conducted on the canned quail meat. In the first experiment, the quality indicators of the freshly prepared product were evaluated. In the second and third experiments, the parameters of the product were determined after aging for one year at temperatures of 2-4°С and 18-20°С. Organoleptic properties and physico-chemical and microbiological parameters were evaluated in the canned goods. The following methods of research were used: during the organoleptic assessment, it was considered the following properties: appearance, color, cross-section, smell, taste; fat content – by the Soxhlet method; hydrogen index (pH) – by the potentiometric method; microbiological indicators – by the horizontal method of counting colonies of microorganisms. It was found that the storage temperature did not affect the bacteriological indicators of the samples, which indicates the high quality of sterilization and excludes biological influence on the quality of canned goods. It has been established that, regardless of the storage temperature, the organoleptic indicators of canned food 12 months after production meet the state standard and the manufacturer's requirements, and they do not differ significantly. After one year of storage, the physico-chemical indicators of canned quail meat are within the limits of indicators established by the standard, regardless of the storage temperature. At the same time, certain changes were detected in the canned goods, which depended on the temperature conditions of storage. Considering the trends in physico-chemical parameters, the desired storage temperature for canned quail meat is 2-4 °C, although the increase in temperature to 18-20 °C does not lead to significant changes and it is permissible. Research is scientifically based on establishing the safety and quality of canned minced quail meat during long-term storage conditions, to create and produce high-quality and safe food products, which in turn allows for expanding the assortment of canned meat raw materials.
At present, the positive effect of BioR remedy obtained by original technologies from the biomass of cyanobacterium Spirulina platensis was demonstrated at the Academy of Sciences of the Republic of Moldova on pigs, rabbits and broilers. Considering the fact that remedies of vegetal origin are not harmful to animals, people and environment, they are of particular interest to the most developed branch of animal husbandry – the aviculture, including for the production and exploitation of quail. Until present, studies on the action of the nominated preparation on the physiological-metabolic status, including lipid metabolism in quail for reconditioning have not been conducted. The biological material was 150 quail at the end of the laying cycle divided into 3 batches of 50 birds. The tested preparation was administered intramuscularly to the quails two times consecutively at the onset of the study and secondly at 14 days after the first administration at a dose of 0,5 ml /head. In another experimental batch, the commercial product Butofan was administered in order to compare the obtained results. Birds of the control group received 0,5 ml of solution of NaCl of 0,9 % in both terms. The birds included in the study were analogous in terms of race, age, body weight and physiological status. During all time of the study, quails were monitored: clinical parameters, body weight, and number of eggs. In addition, for laboratory investigations, blood was collected from five quails at the start of the study before the tested preparations were administered and then 2 times during the study. It has been established that the tested remedies do not cause adverse reactions or deviations in quails' health. Moreover, BioR showed adaptive properties, reflected in body temperature lower by 0,32 C than the control group and 0,18 C than the group treated with Butofan. Similar manifestations were also found in birds' breathing. Biochemical researches performed on quails that have benefited from the BioR remedy reveal a true decrease in total lipids in one investigation and an increase in triglycerides at this stage and their decrease at the end of the study. Additionally, both BioR and Butofan remedies induced an increase in the blood serum of ß-lipoproteins at both stages of research, while cholesterol values did not show any essential changes. In conclusion, we can state that the BioR product has a beneficial effect on quail, including their lipid metabolism.
