“…However, the HFP-recovered and the electro-spun collagen-originated nano-fibres exhibited thermal profiles comparable to those of gelatin, suggesting complete denaturation [31,[50][51][52].…”

“…Moreover, the collagen fibrils possess a high degree of axial alignment and exhibit a characteristic D banding (the finger print of fibrous collagens), which results from alternating overlap and gap zones, produced by the specific packing arrangement of the 300nm long and 1.5nm wide collagen molecules. This produces an average periodicity of Furthermore, the denaturation temperature of collagen is higher than the denaturation temperature of gelatin [31,[46][47][48][49][50][51][52] (Differential Scanning Calorimetry Experimentation). Most importantly, the tight triple helical structure of the collagen molecule makes it resistant to pepsin or trypsin, unless its folding is locally compromised by either point mutations or heat denaturation [53] (Pepsin Digestion and SDS-PAGE Experimentation).…”

A well-known, affordable, and cheap method of modifying biopolymers is their simple mixing with synthetic and natural polymers. As a result, similar to metal alloys, polymer-polymer complexes with predetermined properties can be obtained. Although interpolymer complexes became a subject of study and application a long time ago, in domestic practice, the study of natural biopolymers is limited. The purpose of this study was to present and study the issue of structuring in solutions of bio- and synthetic polymers, as with a low dry matter content such structures have many properties of a solid. Natural ampholytic polymers are polyelectrolytes, which is also of great importance for their further study. By analyzing the results of studies of complexes formed by a synthetic linear polyelectrolyte with a charged partner – protein, it becomes possible to create new “smart” polyelectrolyte complexes that can undergo phase changes in narrow, controlled pH ranges. The positive effect of sodium carboxymethyl cellulose on the gelation of 5% gelatine hydrogels was established. It was determined that the presence of additives of inorganic salts leads to an increase in the swelling of gelatine gels. It was established that more durable gels are less prone to aging. The practical significance of these studies is determined by the fact that in many industries (food, soap, paint, and varnish), it is necessary to obtain structures with tailor-made properties. Gel formation may also be an undesirable phenomenon that must be prevented, for example, in the production of chemical fibers, glues, and tanning solutions. Furthermore, biological objects themselves in most cases, by their nature, are protein gels with specific mechanical properties. Keywords: structure and dynamics of gelatine mixed hydrogels, adsorption on solid surfaces, collapse of heterogeneous networks, swelling and aging of mixed gelatine hydrogels.

“…11 DSC appears to be the most convenient and widely used method, which has already been used to directly exploit the melting temperature of gelatin gels. [21][22][23][24] However, to the best of our knowledge, the influence of salt on the thermal stability of gelatin gels has not been systematically studied, and little information is available in relation to this respect. 19 The strategy for this study was the following.…”

The effects of preparation conditions, such as polymer concentration, annealing temperature, annealing time and pH, on the melting behavior of gelatin gels were investigated. An optimum condition of gel preparation for calorimetric test is obtained. In addition, the influence of salt including salt concentration and salt type on the melting behavior of gelatin gels was explored by DSC and rheometer. It was found that the melting temperature first increased and then decreased with an increase in salt concentration. This result indicates that electrostatic interactions are important for the formation and stability of gelatin gels. Moreover, the melting temperature of polymer gels with different salt addition conforms to the following orders: Na +
