Rice bran solubles are a nutritional product derived from the bran shavings produced as brown rice is converted into white rice. The shavings are usually discarded or used for animal feed. In Japan, they are used in some traditional pickling recipes. To produce rice bran solubles, the bran shavings are heat treated to prolong shelf-life and then enzymatically extracted to collect water-soluble components.
What Are the Health Benefits
Rice bran — the nutrient-rich outer hull of rice kernels that’s produced as a by-product of white rice processing — makes a welcome addition to cereals or smoothies. Stabilized rice bran has a longer shelf life than un-stabilized rice bran, because it undergoes processing that inactivates an enzyme that would otherwise degrade the rice bran oil, turning it rancid. Stabilization does not affect the nutritional value of the rice bran. Consuming stabilized rice bran offers a number of health benefits, because it serves as an excellent source of essential nutrients.
Consume stabilized rice bran as a source of dietary fiber. Following a diet rich in fiber helps you maintain a healthy weight, keeping your stomach fuller for longer after your meal to prevent over-eating later in the day. The fiber in stabilized rice bran also helps control your blood sugar levels and offers long-term health benefits, including a lower risk of heart disease. A quarter-cup serving of stabilized rice bran offers 6.2 grams of dietary fiber — 25 percent of the daily intake recommendation for women and 16 percent for men, according to the Institute of Medicine.
Manganese and Phosphorus
Stabilized rice bran serves as a good source of essential minerals and provides you with a generous amount of manganese and phosphorus. You need both minerals for healthy bones — phosphorus contributes to the mineralized bone tissue that makes your bones hard, while manganese helps you produce the collagen that makes them resilient to damage. Manganese also promotes healthy brain function, while phosphorus plays a role in cell communication. A quarter-cup serving of stabilized rice bran contains 495 milligrams of phosphorus and 4.2 milligrams of manganese — your entire daily requirements — and 71 percent of the phosphorus you need daily.
Magnesium and Iron
Incorporate stabilized rice bran into your diet to boost your magnesium and iron intake. A quarter-cup serving of stabilized rice bran provides you with 5.5 milligrams of iron — 69 percent of the recommended daily intake for men and 31 percent for women, set by the Institute of Medicine. Each serving also contains 72 percent of the daily magnesium intake requirement for women and 55 percent for men. Both minerals boost your metabolism by helping your cells produce energy. Magnesium also promotes healthy cell communication, while iron helps you produce red blood cells, which are essential for oxygen transport.
Vitamins B-5 and B-6
Stabilized rice bran also contains vitamins, particularly vitamins B-5 ad B-6. Vitamin B-5 plays an important role in brain function — it helps you make melatonin, a brain hormone that affects alertness, as well as acetylcholine, a chemical used in brain cell communication. Vitamin B-6 also helps your nerves communicate and plays a role in red blood cell production. Each quarter-cup serving of stabilized rice brain contains 2.2 milligrams of pantothenic acid, or 44 percent of the recommended daily intake set by the Institute of Medicine. A serving also provides 1.2 milligrams of vitamin B-6, or 92 percent of the recommended daily intake.
