A breakthrough study on retort processing and the addition of stabilisers on ready-to-drink (RTD) milk tea beverages has earned Universiti Kuala Lumpur Malaysian Institute of Chemical & Bioengineering Technology (UniKL MICET) national recognition.
Led by Ts. Dr. Muhamad Yusuf Hasan, the research won a Gold medal at the National Convention on Agricultural and Food Engineering (NAFEC) 2025, as well as the Jury’s Choice Award.
The research team also comprised Nur Syammimi Alias, Azrin Abdul Rahman, Associate Professor Ts. Dr. Zulhafiz Tajudin, and Dr. Fahmi Asyadi Md Yusof. They were honoured at the award ceremony held at Dewan Serbaguna, KPKM, Putrajaya, officiated by YB Datuk Arthur Joseph Kurup, Deputy Minister of Agriculture and Food Security.
This research aligns with UniKL MICET’s focus on chemical and food technology. It demonstrated that heating ready-to-drink milk tea at 121.1°C for 15 minutes effectively eliminates harmful bacteria, ensuring the beverage is safe for consumption.
In addition to the retort process, according to Ts. Dr. Muhamad Yusuf, the study also examines how the use of three stabilisers—salt, sucrose ester, and Polysorbate 20—affects the sensory and nutritional attributes, emulsion stability, and microbial safety of the product.
“The findings offer a practical solution to extend the shelf life and guarantee the microbial safety of RTD milk tea, making it safer and more appealing to consumers.
“By identifying effective stabilisers, particularly salt and sucrose ester, alongside optimal processing conditions, the study provides actionable insights for small and medium-sized beverage producers who may lack resources for extensive R&D,” he said.
Improved sensory quality and product stability can enhance consumer acceptance and satisfaction, supporting the growth of the RTD milk tea market.
Furthermore, the research opens avenues for incorporating functional ingredients while maintaining product stability, potentially contributing to public health through the development of healthier beverage options.
