The cultivation of makhana (Euryale ferox) is a traditional and skill-intensive process primarily practiced in the wetlands and ponds of North Bihar, especially in the districts of Darbhanga, Madhubani, Purnia, and Katihar. This practice, deeply rooted in local culture, has been passed down through generations and forms a vital part of rural livelihoods.

1. Land & Waterbody Selection

• Makhana is cultivated in stagnant water bodies such as ponds, tanks, and low-lying flood-prone areas with a depth of 1.5 to 2.5 feet. These wetlands are selected after the monsoon recedes, as the water level becomes suitable for sowing.

2. Seed Sowing (January to March)

• Mature makhana seeds are sown in shallow ponds or tanks.

• Seeds naturally sink and germinate at the bottom.

• The temperature must remain around 20–30°C for proper germination.

• No artificial irrigation is required since the plant thrives in still water.

3. Growth & Plant Development

• After about 3–4 weeks, the seedlings begin to emerge with large floating leaves that cover the water surface.

• The plant grows extensively across the pond, forming a thick green mat.

• Flowering starts during May to June, and the flowers develop into prickly fruit pods.

4. Fruit Maturity & Harvesting (July to September)

• Fruits mature underwater and are manually harvested by traditional divers using bamboo baskets or nets.

• Harvesting is labor-intensive and often done by skilled local workers who dive and collect the pods from the pond bed.

5. Seed Extraction

• The collected fruits are dried for 2–3 days.

• Once dried, they are broken open to extract black seeds, which are sun-dried for further processing.

Traditional Method

The processing of quality makhana involves a series of traditional and scientific steps to ensure that the final product is clean, edible, crunchy, and retains its nutritional value. Here's how premium-grade makhana is processed after harvesting:

1. Cleaning and Washing

• After harvesting, the black makhana seeds (also called gudi) are thoroughly washed with clean water.

• This helps remove mud, dirt, and floating debris.

• Proper drying is ensured to prevent fungal growth.

2. Sun Drying

• Cleaned seeds are sun-dried for 2–3 days to remove surface moisture.

• This step is crucial for preventing spoilage and preparing seeds for uniform roasting.

3. Roasting (Bhunaai)

• Dried seeds are roasted in cast iron pans filled with hot sand at around 250–300°C.

• The process is done in small batches to maintain temperature control and uniform heating.

• Roasting hardens the seed, making it ready for popping.

4. Cooling

• After roasting, seeds are cooled naturally before the next step.

• This cooling prevents cracking or burning during popping.

5. Popping (Phodai)

• Each roasted seed is manually popped using a wooden hammer (phodai hathoda) on a flat stone surface.

• This separates the white puffed kernel from the hard shell.

• Only skilled workers can achieve a high popping rate with minimal breakage.

6. Winnowing & Sorting

• The popped makhana is winnowed to remove leftover husk and unpopped seeds.

• The product is then manually sorted and graded based on:

  • Size (small, medium, jumbo)

  • Color (whiteness)

  • Shape (roundness and fullness)

7. Grading & Polishing

• Grading machines may be used for size uniformity in bulk processing.

• Some makhana undergoes light polishing to enhance appearance (optional and natural).

8. Quality Check

• Samples are tested for:

  • Moisture content (should be <8%)

  • Crunchiness

  • Cleanliness and microbial safety

9. Packaging

• Final product is packed in food-grade, moisture-proof, airtight pouches.

• For exports, nitrogen flushing or vacuum packaging is used to extend shelf life.

10. Storage

• Packed makhana is stored in a cool, dry place, away from sunlight and humidity, to maintain its crunch and freshness.
  
  

Modern Method for Makhana Processing

To meet global demand and food safety standards, the processing of makhana for export now blends traditional techniques with modern technologies. This ensures better hygiene, efficiency, quality control, and longer shelf life, making Indian makhana a premium product in international markets.

1. Mechanized Cleaning & Washing

• Seeds are cleaned using vibrating sieves and air blowers to remove dirt, stones, and dust.

• Followed by automated water washing tanks with filtered water to ensure food-grade cleanliness.

2. Controlled Drying (Solar or Hot Air)

• Instead of open sun drying, solar tunnel dryers or hot air dryers are used for faster and hygienic moisture removal.

• This prevents microbial contamination and reduces drying time.

3. Automated Roasting Units

• Seeds are roasted in temperature-controlled rotary roasting machines, ensuring uniform heating without burning.

• Sandless roasting technology is now also being introduced for cleaner processing.

4. Mechanical Popping Machines

• Replacing manual popping with semi-automatic or fully automatic popping machines, which:

  • Increase productivity

  • Maintain uniform popping

  • Reduce breakage and contamination

5. Optical Sorting & Grading

• Advanced optical sorters are used to remove discolored, burnt, or defective seeds.

• Grading machines sort makhana by size and shape to ensure uniform packaging.

6. Quality Testing Lab

• In-house or third-party quality control labs test samples for:

  • Moisture level

  • Microbial load (E. coli, salmonella)

  • Nutritional content

  • Aflatoxin and pesticide residue

7. Modern Packaging for Export

• Vacuum sealing or nitrogen flushing is used to keep makhana fresh and crunchy.

• Packed in:

  • Food-grade LDPE/laminated pouches

  • Resealable zipper packs for retail export

  • Bulk 10–20 kg bags for B2B export

8. Barcode, Labeling & Certification

• Export packaging includes:

  • Nutritional labels

  • Batch number & expiry

  • FSSAI / ISO / HACCP / USDA Organic / APEDA certifications (as applicable)

  • Barcodes and QR codes for tracking

9. Cold Chain Storage & Logistics

• Products are stored in temperature-controlled warehouses to maintain crunchiness and prevent spoilage.

• Exported via air cargo or containerized sea freight with proper documentation like:

  • Certificate of Origin

  • Phytosanitary Certificate

  • FSSAI Clearance

  • Bill of Lading & Commercial Invoice

Export-Ready Features

• Hygienically processed & packed

• Long shelf life (up to 12 months)

• Global food safety compliance

• Attractive retail-ready packaging

This careful combination of traditional expertise and modern hygiene ensures the production of premium-quality makhana suitable for both domestic use and international export.

Transportation of Makhana: From Farm to Global Markets

Efficient transportation is critical in maintaining the quality, freshness, and crunchiness of makhana, especially when it's being exported.
