Origin & Processing

From Pond to Precision Caliper

How Bihar's harvest becomes standardized export-grade Makhana through traditional roasting and modern optical machines.

Traditional Makhana popping in Bihar
Stage 1 • Roasting & Puffing

Wood-Fired Cast Iron Popping

Hard aquatic seeds are roasted at calibrated high heat and hand-popped on wooden anvils to expand into snow-white Phool Makhana.

Optical color sorting machine for Makhana
Stage 2 • Optical Color Sorting

Automated Color Separation

High-speed cameras identify and discard discolored or bruised kernels to maintain uniform bright ivory color purity across every export batch.

Makhana size grading and caliper inspection
