About
Red sorghum (Sorghum bicolor) is a gluten-free ancient cereal grain distinguished by its red pericarp, which is rich in 3-deoxyanthocyanidins, tannins, phenolic acids, and other antioxidant polyphenols. It is used as a whole grain staple food, flour substitute, natural food colourant, and functional food ingredient across Africa, Asia, and increasingly in Western gluten-free markets.
Safety summary
Red sorghum is broadly safe for the general adult population with no established ADI restrictions; it is a recognised whole grain with a favourable safety profile across major jurisdictions. High-tannin varieties may reduce protein and mineral (Fe, Zn) bioavailability, and diets heavily dominated by sorghum without diversification carry a theoretical risk of tryptophan/niacin deficit (pellagra risk). No IARC classification exists; no bans in any major jurisdiction.
Regulatory landscape
| Jurisdiction | Status | Note |
|---|---|---|
| FSANZ (Food Standards Australia New Zealand) (Australia) | Approved | Sorghum grain is permitted as a cereal food under the Australia New Zealand Food Standards Code; no ADI established.source |
| EFSA (European Food Safety Authority) (European Union) | Approved | Sorghum is recognised as a conventional cereal food under EU food law; no specific additive authorisation needed for whole grain use. Sorghum-derived 3-deoxyanthocyanin colorants are under ongoing novel food/natural colorant review.source |
| FSSAI (Food Safety and Standards Authority of India) (India) | Approved | Jowar (sorghum) is listed as a permitted cereal grain under FSSAI Food Safety and Standards (Food Products Standards and Food Additives) Regulations 2011; no maximum limit set as it is a staple grain.source |
| FDA (Food and Drug Administration) (United States) | Approved | Sorghum grain is recognised as a conventional food/whole grain ingredient. Used as a gluten-free wheat substitute under 21 CFR general food standards; no specific additive listing required.source |
