I’m Yi Xuan, a postgraduate student at Faculty of Science in UTAR, under the supervision of Dr. Tan Chin Xuan and Dr. Teh Lai Kuan. I enrolled in Master of Science by Research Programme.

After completing my Bachelor's Degree in Biotechnology, I decided to further my studies at UTAR, focusing on a research topic: “Effect of sonication duration on the physicochemical properties, microbial load, and shelf-stability of noni juice stored at different temperatures”. Noni (Morinda citrifolia) is a fruit known for its various health benefits, including antioxidant, anti-diabetic, anticancer, and antidepressant properties. It is commonly processed into juice through fermentation or freshly-squeezed methods. Commercial noni juice is typically subjected to pasteurisation to ensure its safety for consumption. However, the heat generated during pasteurisation can potentially degrade heat-sensitive nutrients and bioactive compounds, leading to a reduction in the nutritional content of the juice. To address this concern, sonication has been proposed as an alternative food processing method to pasteurisation, aiming to improve the nutritional content, reduce microbial load, and enhance the shelf-life of fruit juice. This research findings have the potential to contribute to the production of high-quality fruit juice with increased nutritional content using sonication as a food processing technique in the industry.

Undertaking this programme has been an incredibly rewarding journey. Throughout my master’s degree, I have acquired invaluable skills that have shaped me both personally and professionally. One of the key skills I developed is time management, as conducting research requires precise planning and organisation. The extensive nature of the project taught me the importance of patience, as achieving meaningful results often requires patience and dedication. I have also acquired problem-solving skills during the programme. I was frequently faced with challenges, which pushed me to think critically and come up with solutions. These problem-solving skills is invaluable, not only in my academic journey but also in various aspects of my life. Furthermore, the programme also offered opportunities for me to present my research and findings to the domain experts and lecturers during proposal defense, work completion seminar, viva voce, and conferences. With such opportunities, I managed to strengthened my presentation skills and developed self-confidence. 

The environment at UTAR has been very conducive for learning. I am incredibly grateful for the cool and calm environment that allowed me to focus on my studies. The fellow students are friendly and supportive, creating a sense of companionship that made the journey even more enjoyable. The staff members at UTAR are professional and helpful, always going above and beyond to make things possible and easy for me. I would be remiss if I did not express my greatest gratitude to my supervisors, Dr. Tan Chin Xuan and Dr. Teh Lai Kuan. Their unwavering support and guidance throughout my research journey have been significant in my success. Their expertise and professionalism have provided me with a solid foundation and inspired me to strive for excellence.
