Every festive season, millions of Malaysians line up for dodol, kuih and traditional snacks without ever thinking about the machines behind them. Yet behind much of that production stands one woman whose work quietly powers small factories across the country. Her name is Prof. Ts. Dr. Rosnah Shamsudin, and to thousands of food entrepreneurs, she is simply known as Malaysia’s Queen of Machines.
The title is not decorative. Over the past two decades, Prof. Ts. Dr. Rosnah Shamsudin, a professor at the Department of Process and Food Engineering, Faculty of Engineering, Universiti Putra Malaysia (UPM), has designed more than sixty patented food processing machines that allow small producers to work faster, produce more and earn better incomes.
In a field long dominated by heavy industry and male engineers, she chose a different path by building technology for people who run businesses from small workshops and family kitchens.
A Rural Childhood That Shaped an Inventor
Dr Rosnah did not grow up in privilege. She was raised in a rural home as the daughter of a Tenaga Nasional technician and a full time homemaker. Life was simple, but discipline and determination were deeply ingrained. Those values stayed with her long after she entered the world of engineering.
She once summed up her life philosophy by saying, “Where there is determination, there is effort, and where there is effort, there is success.”
That belief carried her to Universiti Putra Malaysia, where she began her academic career in 2001 and eventually rose to become a professor in food and process engineering.
Listening Before Inventing
Instead of staying inside laboratories, Dr Rosnah spent years speaking directly with food entrepreneurs. Many told her they could not meet festive demand. They were exhausted by manual production. They struggled to hire enough workers to grow.
“The machines I develop are meant to save time and energy while increasing production, because small businesses cannot afford inefficiency,”she shared.
That mindset shaped everything she built. Her machines were designed to be practical, affordable and easy to operate while delivering industrial level consistency.
The Machine That Changed Everything
In 2003, she introduced the Ezy Cooker, a specialised machine for making dodol and jam. It took years of research and testing, but when it finally reached producers, it transformed how traditional sweets were made.
Dr Rosnah has often spoken about this invention with emotion, saying, “This machine will always be special to me because it was the one that opened the door to all my later innovations.”
From that single breakthrough came dozens of new machines that helped small producers scale without losing the soul of their products.
Sixty Innovations With Real Impact
Today Prof. Dr Rosnah holds more than sixty registered intellectual property rights, many of which are already in commercial use across Malaysia.
These machines are not theoretical designs. They operate daily in real kitchens and factories, helping businesses increase output, improve quality and stay competitive.
In 2013, her contributions earned her the title Ratu Mesin, or Queen of Machines. She later received the Vice Chancellor’s Fellowship Award in 2021 and the Best Community Network Project Award in 2018, honours that recognised how her work bridges academia and real economic impact.
In 2025, Dr Rosnah was appointed President of the Malaysian Society of Agricultural and Food Engineers. The role places her at the centre of national conversations about food technology, innovation policy and SME development.
Turning Durian Waste Into New Value
One of her most recent innovations shows how far Dr Rosnah’s thinking has evolved. Malaysia may love durian, but once the flesh is eaten, the thick, spiky skins are usually dumped in bins or by the roadside, where they become breeding grounds for mosquitoes and attract rats and flies.
She developed the M’SReD durian skin shredder, which transforms durian husks into valuable raw materials for new products instead of letting them rot in landfills. The machine can also process jackfruit, cempedak and banana peels, turning stubborn organic waste into material that can be reused.
This invention supports sustainability while opening new revenue streams for businesses, proving that innovation can serve both the economy and the environment.
A Legacy That Lives Inside Thousands of Small Businesses
Prof. Dr Rosnah Shamsudin’s story is not just about engineering. It is about how one woman quietly empowered thousands of Malaysian entrepreneurs by giving them the tools to grow, compete and survive.
Her legacy is written into the rhythm of thousands of small factories, into the hands of traditional food makers who can now meet the market, and into the growth of businesses that no longer have to stay small.
