It has been shown that the use of a fermented milk composition as an acidic agent makes it possible to obtain a biopolymer with the maximum preservation of peptide bonds, which is confirmed by a higher dynamic viscosity compared to biopolymer 2, for which lactic acid was used. Based on the results of the studies, it was found that biopolymers 1 and 2 belong to non-Newtonian fluids and exhibit thixotropic properties, which are characterized by a decrease in dynamic viscosity depending on the duration of the spindle rotation. The dynamic viscosity of biopolymer 1 was 14133.3 cPs, and that of biopolymer 2 \u2014 2500 cPs.<\/p>\n<p style=\"text-align: justify;\"><strong>Keywords:<\/strong> recycling; leather raw materials; fermented milk composition; lactic acid; dynamic viscosity<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Shalbuev Dmitriy Valer\u02b9evich East Siberia State University of Technology and Management, Ulan-Ude, Russia E-mail: shalbuevd@mail.ru ORCID: https:\/\/orcid.org\/0000-0003-0077-9977 Tumurova Tuyana Bulatovna East Siberia State University of Technology and Management, Ulan-Ude, Russia E-mail: tumurova_t@mail.ru ORCID: https:\/\/orcid.org\/0000-0002-2371-5549 Abstract.
