Do rice cookers have any safety features to prevent boiling over?

Many modern rice cookers are equipped with safety features, such as automatic shut-off systems and pressure sensors, to prevent boiling over and ensure user safety. These features help regulate the cooking process and prevent excessive pressure buildup within the cooker.

What Rice Has the Least Starch?

Obviously, if starch is what causes rice cookers to boil over, it makes sense to consider using lower-starch kinds of rice, right?

There are two different types of starch found in rice:

  • Amylose
  • Amylopectin

Amylose helps keep rice kernels from getting mushy and you end up with a bowl of perfectly separated grains of rice in the finished dish.

For you keto fans, it’s worth noting that rice with a lot of amylose has a lower glycemic index number. Long grain white rice has the highest amount of amylose of any of the types of rice.

When you cook rice, no matter which type of starch is present, it will naturally get released into the water.

Amylopectin rice tends to be a lot stickier, and in fact, works great for things like rice pudding or maybe risotto. Most short-grain rice is high in amylopectin (and low in amylose).

So which type of starch is more likely to make your rice cooker boil over?

As you may have guessed from the descriptions, amylose starch will be less likely to cause your rice cooker to boil over. So if you routinely have this issue, try using one of these types of rice that are high in amylose starch and low in amylopectin starch:

  • Long grain white rice
  • Basmati
  • Jasmine

But also see my tips below which can help no matter what type of rice you are using.

Since Jasmine and Basmati are most-often used in Thai and Indian food respectively, if you’ve ever wondered about the differences between Thai and Indian curry, I have a recent article that covers those differences from A to Z, and I even touch on all the other countries that have curries.

What’s really surprising is that most of them don’t even use the leaves of the curry plant (but one does). Just click the link to read it on my site.
