Researchers from the University of Birmingham are rethinking one of the world’s most familiar staples and asking a simple but intriguing question. Can ordinary white rice become healthier just by changing how it is cooked?
Their findings suggest it can. By boiling rice in spearmint-based extracts, the team found that grains absorb phenolic acids, natural compounds known for their antioxidant benefits. The process works much like cooking rice in broth, where flavor seeps into every grain, except this time the payoff is added nutrition.
What makes the approach compelling is its flexibility. The researchers showed that nutrient absorption can be adjusted by varying the strength of the herbal solution, the cooking time, and the type of plant extract used. In practical terms, rice can be tailored to carry specific levels of beneficial compounds, opening new possibilities for both consumers and food producers.
There is, however, a catch. Longer cooking times allow more nutrients to enter the grain but may affect texture and taste. That creates a delicate balancing act. Ready-to-eat fortified rice may benefit from longer cooking with moderate extract strength, while quick-cooking versions may require stronger solutions and shorter cooking times to preserve quality after drying and rehydration.
From an industry perspective, the method is notably practical. It can be integrated into existing rice processing systems such as parboiling units with only minor adjustments. This lowers the barrier to producing fortified rice at scale and could enhance both the nutritional and commercial value of a global staple.
The research is still in its early stages. Scientists say more work is needed to understand how other nutrients, including vitamins and minerals, behave during the process.
Even so, the idea is quietly transformative. The next evolution of rice may not come from new varieties, but from what goes into the pot.
