Makhana, or Phool Makhana/Fox Nut, is the popped seed of the aquatic plant Euryale ferox. Chemically, it is primarily a starch-rich plant food, with smaller amounts of protein, dietary fibre, lipids, minerals, and bioactive compounds.
Typical nutritional/chemical composition
The exact composition varies with cultivar, growing conditions, maturity, processing and popping method, so these should be treated as approximate rather than fixed specifications.
| Component | Typical characteristic |
|---|
| Carbohydrates | Major component, predominantly starch |
| Starch | The principal carbohydrate |
| Protein | Moderate amount |
| Dietary fibre | Present |
| Fat/Lipids | Relatively low |
| Moisture | Low in properly dried/popped product |
| Ash/Minerals | Present in small quantities |
| Minerals | Includes calcium, phosphorus, magnesium, potassium and iron |
| Amino acids | Contains several essential and non-essential amino acids |
| Bioactive compounds | Phenolic compounds and other antioxidant-related constituents have been reported |
1. Carbohydrates and starch
The most important chemical component of Makhana is starch. This is responsible for much of its characteristic structure and contributes to the expansion that occurs during the popping process.
The starch consists primarily of:
The proportion and structural characteristics of these starch fractions can influence texture, digestibility and popping characteristics.
2. Protein
Makhana contains plant protein with a range of amino acids. Its protein composition makes it useful as a plant-based food ingredient, although it should not automatically be described as a complete protein source without appropriate amino-acid analysis.
3. Lipids
Makhana is naturally low in fat compared with many conventional snack foods. This is one reason plain roasted Makhana is often positioned as a lighter snack.
4. Dietary fibre
Makhana contains dietary fibre, although the amount can vary substantially depending on whether you're analysing the raw seed, popped kernel, or a processed product.
5. Minerals
Makhana contains various minerals, including:
Calcium • Magnesium • Phosphorus • Potassium • Iron
The actual mineral concentration can vary depending on cultivation conditions and processing.
6. Bioactive compounds
Research on Euryale ferox has identified various phytochemicals and antioxidant-associated compounds, including phenolic compounds and flavonoid-related constituents.
