Brown rice protein
Brown rice protein is made from whole-grain brown rice. The rice is milled and slurried, and enzymes break down the starch into sugars that are washed away, leaving a protein-rich solid that is separated, neutralized and dried. Commercial powders are usually about 80% protein (concentrate) or 85 to 90% (isolate). It is a common base for plant protein powders and blends, often paired with pea protein.
Suppliers sell different products under the same name. Specify the one you need.
Around 80% protein, with a slightly gritty texture; the most common grade.
Higher protein (often 85 to 90%) and smoother, sometimes with finer milling.
Made from certified organic brown rice; a large share of the market.
Made from sprouted rice or with a fermentation step, sold for flavor and texture differences.
Compare each result with your own specification when the lot arrives.
Keep sealed in a cool, dry area away from odors. Rice protein is fairly stable as a dry powder, but residual fat can turn stale in warm storage. Shelf life comes from the supplier's specification, with a retest of moisture, micro and sensory on aged stock.
Record heavy metal results for every lot, not just the annual spec, since arsenic and cadmium vary with growing region and crop. Note the country of rice origin and rotate first-expired, first-out.
