The object of research is fish culinary products in the jelly pouring of the menu of conceptual restaurants. The subject of research is the consumer characteristics of gelling fish broth for culinary products based on sensory characteristics. The study used methods for determining the consumer characteristics of fish culinary products based on physical, chemical, aesthetic and sensory analysis. Methods for the preliminary preparation of hydrocolloids as structure-forming agents for the preparation of gelling culinary products with the study of the parameters of the jelly formation process are proposed. The developed ingredient composition of fish culinary products based on low methoxylated pectin and sodium alginate improves the consumer characteristics of the finished dish. This ensures the implementation of strategic decisions in the food industry through the introduction of innovative technologies and the release of products with new consumer and functional properties. It is the new ingredient composition of the fish culinary products in the pouring that opens the priorities in the creation of the wellness products industry with the aim of improving the health of consumers. The active elements of algae are absorbed almost completely through a chemical composition close to that of human plasma. As a result, algae are able to compensate for the lack of elements and contribute to the normalization of metabolism. The use of low-esterified pectin is due to its structure-forming, therapeutic and prophylactic, sorption, antibacterial properties, which are an alternative to antibiotics and synthetic preservatives to prevent bacterial spoilage. The use of dietary supplements based on sodium alginate and pectin in food products provide an adjustable texture with new rheological and functional properties, which have a positive effect on the commodity performance of finished products for promotion on the market of healthy food restaurants. On the basis of the sensory indicator, rational parameters of the recipe of fish culinary products in jelly pouring were determined to obtain a transparent, stable, homogeneous elastic consistency, which will expand the range of the wellness menu of restaurants of the Wellness concept.

In this study, a self-made continuous needleless dynamic linear electrospinning technique is employed to fabricate large-scale graphene (Gr)/carbon nanotubes (CNT)/polyvinyl alcohol (PVA)/sodium alginate (SA) nanofibrous membranes. The synergistic effect of Gr and CNT fillers in the PVA/SA membrane is explored in depth by changing the volume ratio (v/v) of Gr and CNT as 10:0, 8:2, 6:4, 4:6, 2:8, and 0:10. Microstructure, functional group, conductivity, and hydrophilicity of PVA/SA/Gr/CNT membranes was characterized. Results show that the linear electrode needleless electrospinning technique can be spun into 200-nm diameter fibers. The PVA/SA/Gr/CNT fibrous membrane has good hydrophilicity and thermal stability. A Gr/CN ratio of 6:4 possessed the optimal synergistic effect, which showed the lowest surface resistivity of 2.53 × 103 Ω/m2. This study will provide a reference for the large-scale preparation of nanofibrous membrane used as a artificial nerve conduit in the future.

Polymeric materials such as High density polyethylene(HDPE) are ductile in nature, having very low strength. In order to improve strength by non-treated rigid fillers, polymeric materials become extremely brittle. Therefore, this work focuses on achieving pseudo-ductility (high strength and ductility) by using a combination of rigid filler particles (CaCO3 and bentonite) instead of a single non-treated rigid filler particle. The results of all tensile-tested (D638 type i) samples signify that the microstructural features and surface properties of rigid nano fillers can render the required pseudo-ductility. The maximum value of tensile strength achieved is 120% of the virgin HDPE, and the value of elongation is retained by 100%. Furthermore, the morphological and fractographic analysis revealed that surfactants are not always going to obtain polymer–filler bonding, but the synergistic effect of filler particles can carry out sufficient bonding for stress transfer. Moreover, pseudo-ductility was achieved by a combination of rigid fillers (bentonite and CaCO3) when the content of bentonite dominated as compared to CaCO3. Thus, the achievement of pseudo-ductility by the synergistic effect of rigid particles is the significance of this study. Secondly, this combination of filler particles acted as an alternative for the application of surfactant and compatibilizer so that adverse effect on mechanical properties can be avoided.
