How much do 100 grains of rice weigh?

The mass of a single grain of rice varies noticeably. However, the average mass for a grain of white long-grain rice is about 25 mg. If we take 25mg as the average weight of a single grain, 100 grains of long-grain rice will weigh about 2500mg or 2.5g.

What are the parts of a rice grain?

Hull: This is the outermost tough hull or husk of a rice grain. It needs to be removed irrespective of the type of rice.

Bran: This tan-colored layer lies beneath the outer husk. Bran has an excellent nutrition profile due to the presence of important minerals, vitamins, and fiber. The bran may sometimes appear reddish or brown depending upon what pigments are accumulated in the bran. Bran layer may and may not be removed during processing. 

White rice: The bran and hull of the white rice are removed during the processing of the white rice. So, the white rice is just the endosperm of the rice grain.

Germ: Germ is present beneath the hull, and is sometimes referred to as rice kernel. Germ is packed with B vitamins, minerals, and proteins.

What are the types of rice?

Based on length and shape

Long Grain Rice: The length of a single milled grain of the long grain rice is 3-4 times its width. When cooked, long-grain rice turns out light and fluffy with distinct grains.

Medium Grain Rice: The grain of medium grain rice is quite short and wide as compared to the grain of long grain rice. When cooked, medium-grain rice turns out moist, tender, and a little sticky.

Short Grain Rice: The width of a grain of short-grain rice is less than 2 times its length. When cooked, short-grain rice turns out sticky which makes it perfect for sushi. 

Based on texture

Sticky rice: Sticky rice or sweet rice is cultivated in Southeast and East Asia. Sticky rice is a staple for traditional Asian dishes, desserts, and sweets. As the name suggests, sticky rice turns out sticky when cooked, which is why it is ground into rice flour.

Parboiled rice: Parboiled or rough rice is steamed before milling. The steaming process results in starch gelatinization inside the rice grain. Consequently, the rice turns out fluffier and lighter upon cooking. Converted rice is a type of parboiled rice that involves another pre-cooking step. The pre-cooking or parboiling reduces the cooking time of the converted rice significantly.

Based on color

Polished rice: Polished rice or milled rice appears white because it has its bran and germ layer removed during processing.

Brown rice: The germ and bran layer of the brown rice is intact, which imparts it a brown color. Brown rice has a superior nutritional profile due to the presence of nutrient-dense bran and germ layer but it takes a bit longer to cook.

Forbidden black rice: Black rice features a mild nutty flavor and a rich nutritional profile. When cooked, black rice turns out a bit sticky, which makes it perfect for Chinese and Thai dishes like Chinese black rice cake and mango sticky rice. When mixed with white rice in rice pilaf, black rice imparts color to the dish.

Wild rice: Wild rice belongs to the genus Zizania of grasses. Wild rice has a rich protein content and imparts an exotic flavor to dishes. Wild rice can be served alongside stir fry, mushroom soups, or casseroles.

Based on aroma

Basmati rice: A type of long-grain rice that is a top pick for Indian cuisine and other ethnic dishes. When cooked, basmati rice gives off a subtle nutty or popcorn-like flavor.

Jasmine rice: Jasmine rice is also known as Thai-fragrant rice. Jasmine rice is a type of long-grain rice that trunks out sticky when cooked and gives off a subtle jasmine flavor. 

Should you wash rice?

Yes, washing your rice is an important step as it removes the excess starch and pesticide residues from the rice grains. The rice will turn out sticky and produce a lot of foam or bubbles if not washed before cooking. However, if the rice package claims that the rice is enriched with water-soluble vitamins and minerals, washing becomes a deleterious step.
