Glutinous rice, also known as sticky rice, sweet rice, or waxy rice, is a unique type of grain.

It is grown widely across many parts of Asia. This includes Southeast Asia, South Asia, and East Asia. People value this rice for its distinct texture. When cooked, the grains become very sticky and glue-like.

Despite its name, this rice does not contain gluten. It is safe for people who follow a gluten-free diet. The term "glutinous" refers only to its sticky physical properties.

The unique texture of this rice comes from its chemical makeup. Most rice contains two main types of starch: amylose and amylopectin. Glutinous rice is special because it has negligible amounts of amylose. Instead, it has very high levels of amylopectin. It is this specific starch that creates the sticky, cohesive quality when the rice is heated in water.

This texture allows cooks to use the rice in many ways. They can use the whole grains or grind them into a fine flour.

Milled rice appears bright white and opaque. If the bran is left on, the rice can appear purple or black.

There are several different types of glutinous rice cultivars. These include japonica, indica, and tropical japonica strains. These varieties differ based on their grain shape and where they grow best. For example, short-grain varieties are common in Japan.

Some cultures even grow specific colored strains, such as black or purple glutinous rice. These are distinct from the standard white varieties.

Scientists have worked to trace the history of this waxy mutation. A genetic study conducted in 2002 provided important clues. The study found that all glutinous rice samples contained the same specific mutation. This suggests the waxy trait likely had a single origin. Researchers believe the mutation first arose in temperate japonica rice. It likely started in the upland regions of Mainland Southeast Asia. From there, it spread to tropical varieties through a process called gene flow. This spread allowed the rice to become a staple in many different climates.

Glutinous rice is a major part of agriculture in many nations. In Laos, it is incredibly important to the local economy. It is estimated that 85% of the rice produced in Laos is glutinous rice. Because of this, the International Rice Research Institute calls Laos a "collector's paradise." Collectors have gathered over 13,500 samples there. These samples represent more than 3,200 distinct varieties. Globally, the International Rice Genebank has preserved approximately 6,530 varieties. These varieties come from five different continents, including Asia, Africa, and the Americas.

Culinary traditions use glutinous rice to create many famous dishes. In China, it is used for tangyuan, which are sweet-filled dumplings eaten during Chinese New Year.

Another example is zongzi, which are dumplings wrapped in bamboo leaves. In Cambodia, people make desserts like num ple aiy using palm sugar and coconut.

In Indonesia, the rice is often cooked with coconut milk. One traditional method is making lemang, where rice is cooked inside bamboo stems. In Bangladesh, people enjoy binni bhat, which is steamed rice served with fish or meat. These dishes show how the rice adapts to local tastes and ingredients.

Because of its versatile texture, glutinous rice connects many different food systems. It can be a savory breakfast, a sweet dessert, or a snack for travelers. In some regions, it is even used to make alcoholic beverages like tuak or brem bali. The ability to be ground into flour makes it a vital ingredient for baking and thickeners.
