Project Abstract

This project aims to investigate and optimise microencapsulation techniques for the effective delivery and preservation of bioactive compounds in food systems. Bioactive compounds, such as vitamins, antioxidants, and probiotics, have been increasingly incorporated into food products to enhance their nutritional value and health benefits. However, these compounds are often susceptible to degradation during processing, storage, and digestion, which can limit their bioavailability and efficacy. Microencapsulation offers a promising solution to this challenge by providing a protective barrier around the bioactive compounds, thereby increasing their stability and enhancing their delivery to the target site. The project will explore various microencapsulation techniques, including spray drying, emulsion-based methods, and novel approaches such as microfluidics and electrospraying. These techniques will be evaluated for their efficiency in encapsulating a range of bioactive compounds, including vitamins, carotenoids, and probiotics. The project will investigate the impact of different formulation parameters, such as wall material composition, core-to-wall ratio, and process conditions, on the encapsulation efficiency, particle size, and release characteristics of the bioactive compounds. Furthermore, the project will assess the stability of the microencapsulated bioactive compounds under simulated gastrointestinal conditions and during storage, ensuring the preservation of their functional properties and bioavailability. This evaluation will involve advanced analytical techniques, such as high-performance liquid chromatography (HPLC), to quantify the retention of the bioactive compounds within the microcapsules. The optimization of microencapsulation techniques is crucial for the food industry, as it can enable the development of innovative, nutrient-rich food products with enhanced shelf-life and improved health benefits. By successfully encapsulating bioactive compounds, the project will contribute to the expansion of the functional food market, providing consumers with more accessible and effective sources of essential nutrients and health-promoting substances. In addition to the technical aspects, the project will also explore the potential applications of the optimized microencapsulation techniques in various food matrices, such as beverages, dairy products, and bakery items. This will involve the integration of the microencapsulated bioactive compounds into food formulations and the evaluation of their sensory and physical properties, as well as their overall acceptability by consumers. The project's findings will be disseminated through peer-reviewed publications, conference presentations, and industry-specific forums, ensuring that the knowledge and advancements generated by this research are shared with the broader scientific community and the food industry. The project's outcomes will contribute to the development of more efficient and sustainable food processing techniques, ultimately enhancing the nutritional quality and health benefits of food products. Overall, this project aims to establish a comprehensive understanding of the optimization of microencapsulation techniques for bioactive compounds in food systems, paving the way for the development of innovative, functional food products that cater to the growing consumer demand for healthier and more nutritious options.
