About

What it is and where it shows up.

Black rice (Oryza sativa L.) is a pigmented cultivar of rice distinguished by its high anthocyanin content in the aleurone layer, which accounts for its characteristic dark purple-black colour. It is used as a whole grain food, functional food ingredient, and natural colouring agent, valued for its superior nutritional and antioxidant profile compared to white rice.

Safety summary

The regulatory and scientific consensus.

Black rice is a whole grain food with a well-established safety profile and a history of consumption spanning thousands of years across Asia; no established ADI exists as it is a conventional food. Its anthocyanins exhibit anti-oxidative, anti-inflammatory, and cardioprotective effects at typical dietary intakes, with no significant safety concerns identified for the general adult population. Individuals with rice allergies or those sensitive to dietary phytate should exercise standard caution, as black rice contains phytic acid alongside its bioactive compounds.

Regulatory landscape

What food-safety regulators have decided.

Jurisdiction	Status	Note
EFSA (European Food Safety Authority) (European Union)	Approved	Black rice as a whole grain and traditional food is approved for general consumption in the EU. Anthocyanin extracts derived from black rice may be subject to Novel Food regulation (EU) 2015/2283 if substantially concentrated or isolated beyond traditional use; whole grain and conventional flour forms are not classified as novel foods.source
FSSAI (Food Safety and Standards Authority of India) (India)	Approved	Black rice is recognised as a permissible cereal and functional food under FSSAI regulations. It is increasingly promoted under nutritional security and specialty rice programmes. No specific ADI is set for whole grain black rice.source
FDA (Food and Drug Administration) (United States)	Approved	Rice and rice-derived ingredients are recognised as GRAS under 21 CFR 170.30 based on common use in food prior to 1958 and extensive scientific evidence. Oryza sativa has a documented history of cultivation and consumption exceeding 9,000 years. No specific maximum daily intake is mandated for whole black rice as a food. Rice bran extract (GRN 000884) and rice protein (GRN 000609) have each received no-objection letters from FDA as GRAS ingredients.source

Who should approach with care

Whose guidance would steer them away.

Kidney Disease — Black rice contains phytic acid and moderately elevated levels of phosphorus and potassium; individuals with chronic kidney disease may need to moderate intake to avoid mineral accumulation, consistent with standard dietary guidance for this population.

Diabetes — Although black rice has a moderate glycaemic index and its resistant starch and anthocyanins help retard glucose release, portion size management is still advisable for individuals with diabetes or impaired glucose tolerance, as it remains a carbohydrate-rich food.

Ibs — The insoluble dietary fibre content of black rice (approximately 2.8 g/100 g) may exacerbate symptoms in individuals with irritable bowel syndrome who are sensitive to high-fibre foods.

Infants — Rice-based products, including black rice, can contain inorganic arsenic; regulatory bodies including the FDA advise varied grain consumption for infants and young children to minimise arsenic exposure from rice-dominant diets.
