Project Abstract

This project aims to optimize the microwave-assisted extraction (MAE) process for the efficient recovery of bioactive compounds from fruit waste, a significant source of untapped economic and environmental potential. Globally, the food industry generates vast quantities of fruit processing waste, which is often underutilized or discarded, leading to substantial economic and environmental concerns. However, these fruit waste streams are known to be rich in various bioactive compounds, such as polyphenols, carotenoids, and vitamins, which possess numerous health-promoting properties and potential applications in the food, pharmaceutical, and cosmetic industries. The primary objective of this project is to develop a sustainable and efficient method for the extraction of these valuable bioactive compounds from fruit waste using microwave-assisted technology. Microwave-assisted extraction has gained considerable attention in recent years due to its ability to enhance the extraction efficiency, reduce processing time, and minimize the use of organic solvents compared to conventional extraction techniques. By optimizing the MAE parameters, such as microwave power, extraction time, solvent-to-sample ratio, and temperature, this project aims to maximize the recovery of bioactive compounds while ensuring high-quality and eco-friendly extracts. The project will commence with a comprehensive literature review to identify the most promising fruit waste sources and the bioactive compounds of interest. This information will guide the selection of fruit waste feedstocks and the design of the experimental framework. Thereafter, a series of MAE experiments will be conducted to evaluate the influence of various process parameters on the extraction yield and the quality of the bioactive compounds. Advanced analytical techniques, such as high-performance liquid chromatography (HPLC), mass spectrometry (MS), and spectrophotometric methods, will be employed to quantify and characterize the extracted bioactive compounds. The project will also explore the potential applications of the optimized fruit waste extracts in various industries. For instance, the bioactive compounds may be incorporated into functional food products, dietary supplements, or cosmetic formulations to enhance their nutritional and therapeutic properties. Additionally, the project will investigate the feasibility of scaling up the MAE process to facilitate the industrial-scale production of these valuable extracts, thereby promoting the circular economy and reducing the environmental impact of fruit waste disposal. The successful completion of this project will contribute to the development of a sustainable and efficient approach for the valorization of fruit waste, transforming a waste stream into a valuable source of bioactive compounds. The optimized MAE process has the potential to enhance the economic viability of fruit processing industries, reduce waste generation, and provide a reliable supply of high-quality bioactive ingredients for various applications. Furthermore, this project aligns with the global initiatives towards a more sustainable and circular economy, where waste streams are seen as opportunities for resource recovery and the creation of added-value products.
