Whole Grain Rice Protein

Whole grain rice protein is a plant-based protein derived from whole grain rice. It is typically produced by milling whole grain rice into flour, then separating the protein from the carbohydrates and fiber through various physical and enzymatic processes. The resulting powder is a concentrated source of protein.

Manufacturers add whole grain rice protein as a protein source in foods and beverages. It is commonly found in protein powders, energy bars, and plant-based meal replacements. Its neutral flavor and good mixability make it a versatile ingredient for boosting the protein content of products.

Whole grain rice protein is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of essential amino acids, though it may be lower in lysine compared to some other plant proteins. International bodies like JECFA have evaluated protein ingredients, and EFSA has also reviewed plant proteins. Evidence does not suggest adverse health effects from typical dietary intake.
