Item PREPARATION AND CHEMICAL PHYSICAL CHARACTERIZATION OF INDIVIDUAL NANOSCALED FIBRILS(Bentham Science Publishers, 2022-04-26) Praveetha, Senthilkumar; Sharmila, Chandran; Alexey, Kartsev; Vladimir, Shavrov; Petr, Lega; Ramesh, SubramaniPolymer-based nanofibril finds its application in various fields including tissue engineering, environmental monitoring, food packaging, and micro/nanoelectromechanical systems. These nanofibrils are subjected to chemical treatment and constant stress, which may cause permanent deformation to the fibrils when it is used. Therefore, the synthesis of well-defined nanofibrils and characterization techniques are key elements in identifying desired chemical and physical properties for suitable applications. Many methods have been developed to prepare individual nanofibrils, including electrospinning, phase separation, template synthesis, and self-assembly. Among all, self-assembly offers simple, efficient, and lowcost strategies that produce high-ordered nanofibrils using noncovalent interactions including hydrogen bonding, electrostatic interactions, π-π interactions, and hydrophobic interactions. The first part of the review provides detailed molecular interactions and simulations that can be controlled to achieve the formation of well-defined individual nanofibrils. The second part of the review describes the various existing tools to characterize the chemical and physical properties of single nanofibrils including atomic force microscopy. In the final part of the review, recently developed novel nanotools that measure the mechanical properties of nanofibrils are described. By bridging the gap between molecular interactions and resulting nanoscale fibirls, physical and chemical properties may lead to the construction of novel nanomaterials in the area of nanoscience and nanotechnology.Item RESVERATROL-LOADED Β-LACTOGLOBULIN NANOFIBRILS TO PREVENT ENZYMATIC BROWNING ON SLICED APPLE(Applied Food Biotechnology, 2022) Praveetha, Senthilkumar; Vladimir, Shavrov; Petr, Lega; Ramesh, Subramani: Resveratrol is a polyphenol with nutraceutical health benefits used as anticancer, antioxidant and anti-inflammatory with cardio protective effects. However, resveratrol lacks solubility and bioavailability and is affected by UV light, which decrease its use in food industries. It is possible to overcome these problems by loading resveratrol with appropriate biomaterials. Beta-lactoglobulin is known to form well-defined nanofibrils with various uses. The objective of this study was to use β-lg nanoscaled fibrils to increase bioavailability of resveratrol as well as preserving freshness and preventing enzymatic browning of sliced applesItem ENCAPSULATION OF INULIN LOADED OVALBUMIN NANOFIBRILS IN TONED MILK TO ENHANCE THE NUTRITIONAL VALUE(2022) Praveetha, Senthilkumar; Praveetha, Senthilkumar; Arunadevi, Natarajan; Vladimir, Shavrov; Petr, LegaSelf-assembled nanofibrils encapsulation was performed in the application of nutritional enhancement of toned milk. Inulin loaded nanofibrils (self-assembled ovalbumin nanofibrils) were used for the encapsulation of toned milk. The physico-chemical parameters and nutritional value of inulin loaded ovalbumin nanofibrils were determined. The physic-chemical analysis of toned milk, such as pH, titrable acidity, anti-oxidant activity, encapsulation efficiency, and in-vitro release, were calculated. The results show that sensory characteristics were not affected by encapsulation of nanofibrils on toned milk. The nutritional values of inulin loaded ovalbumin nanofibrils in toned milk was performed using conventional oven drain method (moisture), ignition method (ash), gerber method (protein), kjeldahl method (fat), pearson's composition analysis (carbohydrates), titration method (lactose), and HPLC method (Vitamin D). The result shows that the protein content is raised and also increased with other nutritional values
