The paper presents the scientific justification for the creation of a food product, that can satisfy the physiological needs of a person in the necessary energy, as well as the functional nature, created taking into account the nutritional value of food. The authors have chosen a method of limiting chemotaxis -the process of directing bacteria to the attractants, thereby preventing the development of microorganisms. The selected source of structural collagen protein -tripe, was cleaned and ground in a meat grinder, treated with diocide (dimethyl sulfoxide (DMSO) + sodium chloride or (CH 3 ) 2 S = O + NaCl), introduced into sausage mince in exchange for lard. Mince was grinded and packed into protein shell, fried, boiled, and smoked. Obtained semi-smoked sausage product became more stable in storage than boiled sausage because it contained less moisture, had a high nutritional value and functionality. DMSO has been proven to have antioxidant effects. It prevents the oxidation of lipids by H 2 O 2 and inhibits free radicals such as OH.
The article provides a comparative analysis of data on the content of macro-and micronutrients, as well as the determination and identification of biologically active substances in the bioextracts obtained with distilled water (BE-I) and 70% ethanol (BE-II) from the shell of the common hazelnut (Corylus avellana L.) plant widespread in the northwestern region of Azerbaijan. It was established that the bioextracts BE-I and BE-II have the same mineral composition and contain 25 mineral elements. The bioextracts obtained by extraction with distilled water and 70% ethanol contain 28.51% and 14.61% mineral elements respectively.
The enrichment of the molecular structure of silk fibroin by selenium atom led to an increase in the branching of fibroin macromolecule. As a result, the amorphous fraction of fibroin microfiber increases which leads to an increase in the strength characteristic of the silk thread. At the same time, this change in the supramolecular structure of fibroin involving a selenium atom has enabled us to study the two-modification mechanism for crystallizing fibroin microfibers. Based on studies on the use of temperature-gravimetric and X-ray diffraction (XRD) analysis and relative changes in the proportion of amorphous and crystalline regions, we came to the conclusion that fibroin microfibrils consist mainly of extended crystallites CSC – crystallites with the stretched chains. They alternate along the axis of microfiber with amorphous layers, the sizes of which are smaller than the sizes of the folded crystallites (CFC). Therefore, CFC cannot be located in amorphous layers between the CSC along the microfiber’s axis. As a result, the ability to fold branched sections of the macromolecule decreases, that is, CFC decreases. This increases the proportion of amorphous areas of microfibers of the fibroin. In the model, which is proposed by author non-crystallized in the form of CSC, segments of a macromolecule, on the sides of the central core and attached to it, restored their crystal structure (CFC) – with folded conformation of chains.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
