Rice is loved all over the world and Australia is no exception; from scrumptious sushi to perfect paella we’ve embraced every righteous rice dish that comes our way. Our obsession with rice isn’t going anywhere, but unfortunately, our waistlines are, and too much white rice isn’t helping. So, what can Australia’s national science agency do to help keep our food tasty and our bodies healthy? Team up with the Chinese Academy of Sciences to make a super-healthy rice of course!
In the thick of it
Before we chow down on our tasty innovation, let’s have a quick recap on the difference between some rice varieties. You’ve probably heard of brown rice and white rice, but did you know they’re from the same grain? White rice starts out as brown rice but then the grain is ‘polished’ of the outside layers: the husk, bran and germ. It makes it quicker to cook but it also gets stripped of most of the nutrients and fibre, making it a lot less healthy.
Thankfully, the demand for healthier varieties of rice has been on the rise in recent years, and that’s where our innovation comes in. We’ve identified a variety of rice that has an outer layer (called the aleurone) that is four to twelve times thicker than usual rice. By studying this variety, we’ve uncovered the gene responsible for the tiny change that makes this dramatic shift happen in grain development.
This breakthrough means it may be possible to get all the nutritional value and gut health promoting fibre of wholegrain rice from varieties we prefer to eat. And if a healthier version of brown rice doesn’t appeal to you, the thick aleurone grain means food processors have more options to lightly polish and retain some of the many healthy properties of the rice while approaching the taste and texture of white rice. The new and improved grain can also be turned into a delicious wholegrain rice flour, making the base of so many meals extra nutritious.
Wheat until you see what’s next…
This new innovation has been successfully tested by breeders in China in red and black-grained rice varieties which are increasingly popular as wholegrain foods in China. The new varieties are being grown with little or no effect on growth and yield of the rice, so it’s a win for farmers and a win for consumers.
With our newfound understanding of the gene that makes more of the healthy outer layer, we’re teaming up with the Chinese Academy of Sciences and the Chinese Academy of Agricultural Sciences to see if we can use that knowledge to create healthier wheat, barley and sorghum. We’re also working with our friends at the University of Melbourne to further increase the nutritional content of our rice-based culinary creations.

So what is the name of the rice and can we purchase it?

The rice isn’t commercially available yet and we’re seeking commercial partners. But recently we test cooked the rice in China as congee and it tasted good!

Sounds good – where is it?

Again, great work. I see that the article spoke of Chinese being involved in this development but nothing was said about the Australian rice growers cooperative SunRice. Hop this isn’t going to go the way of a high resistant starch wheat developed by CSIRO that is being commercialised by Limagrain,a FRENCH farmers coop.

Great work CSIRO

Looking forward to seeing what comes next!!
