Why grade matters more than brand

In B2B ingredient sourcing, the grade name on your PO determines rehydration ratio, visual appearance, and price. A supplier who cannot explain the difference between flakes and minced is a broker, not an operator.

Flakes (8–15 mm)

Best for: soup bases, ready meals, toppings where visible onion pieces are desired. Typical moisture ≤6%, rehydrates in 8–12 minutes in hot water. Nisvel standard offer: 10–15 mm Grade A flakes from Mahuva belt.

Chopped & minced (3–8 mm)

Best for: seasoning blends, sauces, marinades where smaller particle size improves dispersion. Lower rehydration time than flakes. Specify mesh or mm size on your PO — 'chopped' without a size range is meaningless.

Granules (40–60 mesh) and powder (80–100 mesh)

Best for: spice mixes, snack seasonings, instant noodles. Granules flow better in automated filling lines; powder integrates faster but clumps if moisture exceeds spec. Always request COA moisture and mesh distribution.
