Scientists at Newcastle University have been experimenting with common curry spices such as turmeric, cumin, cloves, coriander (cilantro) and cinnamon to see if they reduce the production of methane gasses.
The scientists created an experiment that simulated sheep’s stomachs and measured the methane that was produced.
And the findings were that the spices do reduce methane output with the best curry ingredient being coriander, which reduced the methane output by a staggering 40%.
There are around 30 million sheep in the UK, and they produce about 600 million litres of methane every day, so a 40% reduction is a huge cut in emissions.
We don’t think that farmers will take to feeding curries to their sheep in the future but it’s possible that curry spices will be added to the livestock feed to help cut down on farm-produced methane.
