Bioactive constituents in brown rice

Brown rice is less processed than white rice, which has had its hull, bran and germ removed. Brown rice only has the hull (a hard protective covering) removed, leaving the nutrient-packed bran and germ.

In addition to B vitamins, phytochemicals found in brown rice include dietary fiber, functional lipids, essential amino-acids, phytosterols, phenolic acids, flavonoids, anthocyanins, proanthocyanins, tocopherols, tocotrienols, minerals, gamma aminobutyric acid (GABA) and γ-oryzanol. Brown rice also contains high levels of phytic acid.

Bioactive constituents such as γ-oryzanols, tocopherol, tocotrienols, polyphenols, amino acids, dietary fibers, minerals have also been identified from brown rice.

Brown rice has more fiber compared to white. Brown rice also has a touch more fat from the essential oils in the germ, which can cause it to spoil faster than white rice. Brown rice also has fiber in the bran which makes it more difficult for moisture to get absorbed by the grain, and therefore it has a chewier mouth feel.

Brown rice is exceptionally high in manganese. This little-known mineral is vital for many important processes in the body, such as bone development, wound healing, muscle contraction metabolism, nerve function and blood sugar regulation.

Brown rice also offers a healthy dose of magnesium, which helps the body process sugar and produce insulin. Studies have found that magnesium could prevent type 2 diabetes, lower high blood pressure, and prevent cardiovascular disease.

Phenolic acids are the most common substances found in brown rice. Phenolics are classified under phytochemicals having one or more aromatic rings with one or more hydroxyl groups. Phenolic compounds are associated with diverse human health benefits including anti-inflammatory, hypoglycaemic, anticarcinogenic, antiallergenic and anti-atherosclerotic properties.’

Parboiled brown rice

Parboiled brown rice shall be brown rice in which the starch in the kernels has been gelatinized by soaking, steaming and drying the rice.

After harvest, rice is left in it tough outer skin husk and boiled briefly, often under pressure, then dried. The husk is then removed. The brown rice that results has a different appearance and nutritional profile from non-parboiled brown rice, and slightly different cooking characteristics.

Parboiling has the added advantage of improving the keeping qualities of brown rice by neutralizing the substances that cause the oils in the germ to turn rancid. Unlike parboiled white rice, parboiled brown rice always remains the bran and germ.

Rice with inedible hulls removed but the bran left on is brown rice, whereas rice that is further milled to remove the bran is white rice.

Parboiled grain is more resistant to disintegration and dissolution during cooking than raw grain, Parboiled rice is popular in India, Bangladesh and Sri Lanka.
