Ripening agent in imported durians could pose health risks if misused
KUALA LUMPUR: The surge of imported durians in the market has sparked concerns among consumers, following claims that these fruits may contain chemicals potentially linked to chronic illnesses, including cancer. Professor Dr Norsida Man, from the Department of Agribusiness and Bioresource Economics at the Faculty of Agriculture, Universiti Putra Malaysia (UPM), confirmed that a chemical called ethephon is widely used in the agricultural sector. Ethephon (2-chloroethylphosphonic acid) is a plant growth regulator. It is a synthetic compound that breaks down into ethylene gas when absorbed by fruit or exposed to specific levels of moisture and temperature. "The compound reacts with water in the fruit's tissues to release ethylene gas — a natural plant hormone that triggers the ripening process," she said. However, she cautioned that if the fruit is harvested before it fully matures, the ripening process becomes incomplete. This results in fruit that appears ripe but has an inconsistent texture, a weaker aroma, and a less intense flavour. Ethephon is permitted in many countries but is subject to maximum residue limits that must be strictly followed. "Toxic effects can occur if ethephon is overused or if the ripening period before sale is insufficient — typically three to seven days are needed for the residues to break down." "In small doses and when used properly, it is not harmful. But what worries consumers is uncontrolled usage, especially in large-scale export industries driven by profit," she added. Common effects of ethephon use include unnatural taste and smell, inconsistent texture, and unstable quality of the fruit. "Exceeding safe limits may lead to potential long-term health effects such as hormonal disruption and organ damage, especially when used excessively and without regulation. "This issue highlights the dilemma between modern market demands and natural food quality. In the long run, rising consumer awareness could drive demand for more authentic, chemically unaltered durians," she said. Norsida also noted that in Thailand, durians are cultivated in various regions — the south, east, and central areas — allowing for a longer harvest season. The main season runs from March to July, while in southern regions near the Malaysian border, it may extend until September. In Malaysia, the main durian season typically occurs between May and August, particularly in states such as Pahang, Johor, Perak, and Penang. A secondary season, if it happens, typically runs from November to January, depending on weather and regional factors.

Modern agriculture can help mitigate trade war threats, says academic
The government allocated RM6.42 billion to the agriculture and food security ministry in Budget 2025 to implement various policies, especially to boost productivity. PETALING JAYA : Modern, large-scale farming and investment in research can cushion the impact of a trade war on national food security, according to an academic. Norsida Man said the threat of higher tariffs by US president Donald Trump, and its impact on other countries, could reduce global agricultural trade. The Universiti Putra Malaysia (UPM) lecturer said such developments could have a negative bearing on Malaysia as it is a food-importing country with a low self-sufficiency level. 'The savings from targeted fuel subsidies could potentially be redirected to the agricultural sector to boost production and reduce food imports, thereby minimising food security risks caused by trade wars and other threats. 'This proposal could be considered provided the allocation is used appropriately and based on priority,' she told FMT. Another academic, Christopher Teh, highlighted the importance of investing more in the modernisation of agriculture, especially through the use of latest technologies and machinery incorporating artificial intelligence and the Internet of Things. He said modern agriculture should also involve the use of fertilisers and seeds that can increase yields. 'More food processing centres, post-harvest facilities, collection and distribution hubs, and cold chain systems should also be developed to reduce food waste. 'This is because one-third of Malaysia's agricultural produce is lost due to weak logistics,' said the UPM lecturer, who also suggested that all agencies collaborate to expand markets. Teh also said Malaysia, which chairs Asean this year, could diversify import sources among member countries. He hoped to see Budget 2026 provide research centres and higher education institutions with sufficient allocations to develop more climate-resilient crop and livestock varieties. He said research and development should also cover sustainable and environmentally friendly agricultural practices. The government allocated RM6.42 billion to the agriculture and food security ministry in Budget 2025 to implement various policies, with a focus on boosting productivity.
