Influence of protection with protective drugs based on chitosan-copper complexes on reduction of weight of food chicken eggs during storage

Keywords: technology, food eggs, disinfection, chitosan, electrolysis


The paper presents methods of processing edible chicken eggs. Fresh demolished eggs of category C0 65-75 g of breed "Decalb-White" were selected. Stored in clean boxes of 30 piece each. The eggs were divided into groups VII and stored at 21° C. Storage of eggs at room temperature leads to deterioration of quality organoleptic characteristics of egg content, increased rate of penetration and reproduction of Escherichia coli, Staphylococcus aureus, Salmonella enterica, BGKP (bacteria of the Escherichia coli group) in comparison with eggs stored in refrigerators. The aim of the study was to determine the effect of treatment of edible chicken eggs with protective drugs based on "chitosan-copper" complexes on reducing the weight of edible chicken eggs during storage. Formed seven batches of chicken eggs of 30 pieces. in every. The experimental batches were treated with protective drugs of Chitosan-copper complexes, prepared in different ways. The experiment was performed for 30 days. Chicken eggs were divided into separate groups. In order to isolate the content of chicken eggs from the environment, reduce weight loss and prevent microbial contamination, we used the treatment of the surface of the shell of each egg with different substances. The composition of the composition for processing edible chicken eggs on the basis of complexes "Chitosan-copper" for protection against pathogenic microflora of bacterial and viral origin inhibits the loss of egg weight throughout the shelf life. In the experimental group, where chicken eggs were treated with Solution (5), which consists of aqueous chitosan (2-5%) with the addition of peracetic and acetic acid (1: 1 by volume) and subjected to electrolysis using titanium as an anode and cathode, egg weight decreased by 1.3%, 2.4% on day 14, 3.1% on day 21, 7.5% on day 30, which showed the best result. Thus, the decrease in the weight of chicken eggs is influenced not only by the storage temperature, but also by protective preparations based on chitosan-copper complexes, which showed a decrease in the rate of weight loss and spoilage of eggs during storage at 21 ºC. Developed "green" electrochemical technology for the synthesis of protective coatings for food eggs to extend the shelf life / transportation on the basis of complexes such as "chitosan-copper"; 2) It is experimentally proven that the use of technology for protection of eggs for laying chickens, based on the formation on the surface of eggs of a thin layer of environmentally friendly chitosan, which contains copper ions, does not have a statistically significant effect on egg weight reduction compared to control.
