Makhana (Phool Makhana)

About

What it is and where it shows up.

Makhana is the popped starchy seed of Euryale ferox Salisb. (Family Nymphaeaceae), an aquatic plant cultivated primarily in north Bihar and Assam, India, and across East Asia. It is a nutritionally dense whole food rich in carbohydrates (~76.9%), protein (~9.7%), dietary fibre, vitamins, minerals, polyphenols, and bioactive phytochemicals, widely consumed as a snack and deeply embedded in traditional and functional-food systems.

Safety summary

The regulatory and scientific consensus.

Makhana has a multi-century history of safe human consumption across India and China, with no known significant adverse effects at normal dietary intake levels; no Acceptable Daily Intake has been established because it is a whole food rather than a chemical additive. It carries a low glycemic value and a high amino acid index, making it broadly compatible with most dietary patterns. A documented concern is the potential bioaccumulation of heavy metals (Cr, Cd, Pb, Cu) in seeds harvested from polluted or contaminated water bodies, which is relevant for vulnerable populations and underscores the importance of certified, clean-source procurement.

Regulatory landscape

What food-safety regulators have decided.

Jurisdiction	Status	Note
FSSAI (Food Safety and Standards Authority of India) (India)	Approved	Makhana is recognised as a legitimate food product under the Food Safety and Standards Act, 2006. FSSAI has explicitly listed it in its current standards-development agenda for formulation of new formal compositional standards alongside other traditional foods such as millets and puffed rice. No maximum daily intake or use restrictions have been set; it is freely sold and exported as a food/snack product.source

Who should approach with care

Whose guidance would steer them away.

Infants — Seeds sourced from polluted water bodies can bioaccumulate heavy metals (Cr, Cd, Pb, Cu) as documented in published literature; infants are disproportionately vulnerable to heavy-metal toxicity, so only certified, clean-source makhana should be used in infant foods.

Pregnancy — Heavy-metal bioaccumulation potential in seeds from contaminated growing environments poses a heightened developmental risk during pregnancy; pregnant individuals should ensure procurement from quality-certified, uncontaminated water sources.

Kidney Disease — Makhana contains ~0.9% phosphorus per 100 g; individuals with chronic kidney disease on phosphorus-restricted diets should seek medical guidance on appropriate portion sizes.
