Abstract

The costs of food deterioration in terms of both money and health are rising. Fungi, bacteria, yeast, insects, and rodent contamination of food supplies continue to be a major public health concern. Chemical preservatives are effective but can be potentially fatal to human health in certain cases. As potent food preservatives, essential oils made from plants are a great alternative to synthetic preservatives. They also possess a variety of antiinflammatory, antibacterial, and antioxidant effects. The use of artificial sweeteners in food products, which raises safety questions and health issues while also having reduced nutritional value, is another problem in the food industry. Because natural sweeteners are linked to a healthy lifestyle and have superior nutritional qualities, consumers today prefer them. This article goes through the issues with artificial sweeteners and preservatives and goes into great length about the many different essential oils and natural sweeteners that are much safer and healthier alternatives.

Abstract

Radio-frequency identification or RFID is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to objects. This technology has found application in many industries. In this project, the application of RFID in supply chain industry has been explored. In the supply chain industry is it of utmost importance that the location and product details of the goods being moved from one point in the supply chain to another be known at all times. This is the issue that has been addressed in this project. The first part of the project deals with implementing RFID technology in supply chain system. The RFID data is extracted from tags and readers using RFID Middleware. Integrating this RFID data with enterprise applications for business use is an important factor. Different techniques for doing this have been studied and the most effective solution has been provided using Service-Oriented Architecture. In the second part of the project, a prototype supply chain management application has been designed. Small and medium enterprises often cannot afford expensive software tools for managing the business effectively and the cost of setting up Information Technology infrastructure becomes very high. Thus, an approach using Cloud Computing has been suggested here. A cloud based supply chain management application has been developed to cater to such enterprises. Finally, these two parts of the project has been integrated to form an end-to-end system for supply chain tracking using RFID and Cloud computing technology.

Abstract

The biocompatible, biodegradable okra mucilage nanoparticles (MNPs) were synthesised by a facile synthesis process and characterised by employing XRD, FTIR and FESEM studies. These were then encapsulated with the antibiotics (streptomycin, ampicillin and kanamycin) which are widely used in several pathogenic conditions. These antibiotics are susceptible to functional degradation upon exposure to adverse conditions like high temperature, UV, etc. The encapsulation of antibiotics within the mucilage matrix was testified with the aid of x-ray diffraction (XRD), FTIR, UV-vis, dynamic light scattering (DLS) as well as molecular docking estimations. These mucilage nanoparticles were then encapsulated with antibiotics when applied against bacterial strains like Escherichia coli DH5?and Staphylococcus aureus.The results demonstrated augmented bactericidal activity in comparison to the bare form of antibiotics. Our results further depict that the encapsulation of these antibiotics within the mucilage nanoparticles enhances their functionalities and also stabilises these antibiotics in conditions like elevated temperature, UV exposure and prolonged storage. Additionally, Rhodamine-B a fluorescent dye was encapsulated within the okra mucilage nanoparticles and is readily internalised by the human lung fibroblast cells, WI-38. Thus, our findings implicate that these synthesised MNPs are truly multi and can emerge as a promising therapeutic intervention in the coming years.
