Every year, enough palm oil is produced to fill 30,000 Olympic-sized swimming pools, and nearly one-third of it comes from Malaysia. But how does this widely used ingredient get from tree to table?
“It’s a product that touches so many lives,” says Shyam Lakshmanan, a chemical engineer with four decades of experience in palm oil refining. Based in Sandakan, Malaysia, he leads one of the country’s major refineries and has spent much of his career focused on improving efficiency, quality and environmental standards in the palm oil industry.
Palm oil begins its journey from plantations across Malaysia. An oil palm tree typically takes three to four years to mature before it starts bearing fruit. Unlike seasonal crops, oil palm is perennial, meaning the same tree can produce fruit year after year without needing to be replanted. Each tree can yield 14 to 18 fresh fruit bunches annually and remain productive for up to 30 years.
Once the reddish-orange oil palm fruit bunches ripen, they are harvested. Ripeness matters – underripe fruit contains less oil, while overripe bunches degrade quickly. Workers sort and grade the fruit to ensure only the highest-quality bunches move forward.
Timing is crucial. “We aim to get the fruit from plantation to mill within 24 hours,” Lakshmanan explains. “The faster we move, the better the quality.”
At the mill, the fruit undergoes sterilisation. A high-pressure steam treatment is applied which not only deactivates enzymes that can degrade the oil, but also loosens the fruit from the bunch. After threshing, which separates individual fruitlets, the oil is extracted through pressing and then clarified to remove impurities. At this stage, the product is known as crude palm oil – still raw and brightly coloured, and not yet ready to use.
