## Primary Grading Parameters

### 1. Size (Most Critical Factor)

Makhana is primarily graded by size, measured in millimeters.

**Traditional Names and Modern Equivalents**:

| Grade Name | Size (mm) | Description | Price Range (₹/kg) |
|————|———–|————-|——————-|
| **Lawa/Lava** | 16+ mm | Largest, premium | 800-1200 |
| **Murra** | 12-15 mm | Large, popular | 600-800 |
| **Samundi/Samoni** | 10-11 mm | Medium, versatile | 450-600 |
| **Tukda/Bindi** | 8-9 mm | Small | 350-450 |
| **Chatni** | <8 mm | Smallest, economy | 250-350 | **Visual Identification**: - **Lawa**: Approximately the size of a large grape - **Murra**: Size of a marble - **Samundi**: Size of a small marble/large chickpea - **Tukda**: Size of a chickpea - **Chatni**: Size of a lentil **Market Preference**: - **Export Markets**: Prefer Lawa and Murra (uniform, large) - **Domestic Retail**: Murra and Samundi (balanced price-quality) - **Processing/Flavoring**: Samundi and Tukda (cost-effective) - **Institutional/Bulk**: Mixed or lower grades (cost consideration) ### 2. Color **Ideal Characteristics**: - ✅ Pure white to off-white - ✅ Uniform color across batch - ✅ No yellowing or browning - ✅ Natural appearance **Color Defects and Causes**: | Defect | Appearance | Cause | Impact | |--------|------------|-------|--------| | Yellowing | Pale yellow tinge | Over-roasting, age | 5-10% price reduction | | Brown spots | Dark brown areas | Burning during roasting | 10-20% price reduction | | Blackening | Black patches | Excessive heat, mold | Rejected/very low price | | Uneven color | Patchy appearance | Inconsistent processing | 5-15% price reduction | **Color Grading**: - **A Grade**: Pure white, uniform - **B Grade**: Off-white, minor variations - **C Grade**: Yellowish, significant variations ### 3. Moisture Content **Critical Parameter for Storage and Shelf Life** **Ideal Ranges**: - **Raw Makhana (after sun-drying)**: 12-14% - **Processed Makhana (ready for packaging)**: 6-8% - **Export Quality**: <6% **Testing Methods**: 1. **Professional**: Moisture analyzer (₹30,000-80,000) - Accurate to 0.01% - Takes 10-15 minutes - Essential for serious processors 2. **Practical Field Test**: - Break a makhana - should snap crisply - Soft or rubbery = high moisture - Should sound hollow when shaken **Moisture Impact**: - **<6%**: Excellent, long shelf life (18+ months) - **6-8%**: Good, standard shelf life (12 months) - **8-10%**: Acceptable for immediate sale only - **>10%**: Risk of mold, reduced quality, short shelf life

### 4. Breakage Percentage

**Definition**: Proportion of broken or damaged pieces in a batch

**Acceptable Limits**:
– **Premium Grade**: <5% breakage - **Standard Grade**: 5-10% breakage - **Economy Grade**: 10-20% breakage - **Rejected**: >20% breakage

**Common Causes of Breakage**:
– Poor handling during transportation
– Over-drying (makes brittle)
– Mechanical damage during processing
– Pest damage
– Age and deterioration

**Economic Impact**:
Each 5% increase in breakage typically reduces value by 10-15%

### 5. Puffiness/Pop Quality

**What is Puffiness?**
The extent to which makhana has expanded during roasting process.

**Ideal Characteristics**:
– Light and airy texture
– Hollow interior clearly visible
– Thin, crisp walls
– Consistent pop across batch

**Grades**:
– **Full Pop**: 100% expanded, premium
– **Good Pop**: 85-99% expanded, standard
– **Partial Pop**: 70-85% expanded, economy
– **Poor Pop**: <70% expanded, rejected/animal feed **Testing**: - Visual inspection - Weight-to-volume ratio (well-popped is lighter) - Cross-section examination ### 6. Cleanliness and Purity **Foreign Matter**: Should be completely absent or <0.1% **Types of Contamination**: - Husk pieces (black shells) - Dust and dirt - Other seeds or grains - Stones or grit - Insect parts **Cleaning Standards**: - **Export/Premium**: Zero visible contamination - **Retail Standard**: <0.1% foreign matter - **Bulk/Economy**: <0.5% foreign matter **Financial Impact**: - Each 0.5% contamination = 10-20% price reduction - Presence of stones/metal = automatic rejection ### 7. Uniformity **Within-Batch Consistency**: **Size Uniformity**: - Premium: 90%+ within 2mm size range - Standard: 80%+ within 2mm size range - Economy: 70%+ within 2mm size range **Color Uniformity**: - Premium: No visible color variation - Standard: Minor variations acceptable - Economy: Visible but not extreme variations **Shape Uniformity**: - Premium: 90%+ well-formed, round - Standard: 80%+ well-formed - Economy: Some irregular shapes acceptable ### 8. Crispness/Texture **Ideal Texture**: - Crisp snap when bitten - Light, airy mouthfeel - Melts quickly in mouth - Not chewy or rubbery **Defects**: - Rubbery texture = excess moisture - Hollow sound but hard = over-roasted - Chewy = partially processed or aged - Soft/soggy = moisture absorption **Shelf-Life Indicator**: Loss of crispness is the first sign of quality deterioration ## Comprehensive Grading System ### Premium/Export Grade (A+) **Size**: Lawa/Murra (12mm+) **Color**: Pure white, uniform **Moisture**: <6% **Breakage**: <3% **Puffiness**: 95%+ full pop **Cleanliness**: Zero visible contamination **Uniformity**: 95%+ within specifications **Price Range**: ₹800-1200/kg **Best For**: Export, premium retail, gifting **Packaging**: High-barrier, nitrogen-flushed **Target Market**: International, urban premium stores ### Standard/Retail Grade (A) **Size**: Murra/Samundi (10-15mm) **Color**: Off-white, minimal variation **Moisture**: 6-8% **Breakage**: 5-8% **Puffiness**: 85-95% good pop **Cleanliness**: <0.1% foreign matter **Uniformity**: 85%+ within specifications **Price Range**: ₹500-700/kg **Best For**: Domestic retail, online sales **Packaging**: Metallized pouches **Target Market**: Middle-class urban, health-conscious ### Economy/Bulk Grade (B) **Size**: Samundi/Tukda (8-11mm) **Color**: Off-white to light yellow **Moisture**: 8-10% **Breakage**: 10-15% **Puffiness**: 75-85% good pop **Cleanliness**: <0.5% foreign matter **Uniformity**: 75%+ within specifications **Price Range**: ₹350-500/kg **Best For**: Institutional, bulk buyers, processing **Packaging**: Simple printed pouches, bulk bags **Target Market**: Caterers, hostels, budget stores ### Industrial/Processing Grade (C) **Size**: Mixed, including Chatni **Color**: Variable **Moisture**: 10%+ **Breakage**: 15-25% **Puffiness**: Variable **Cleanliness**: <1% foreign matter **Uniformity**: Not critical **Price Range**: ₹250-400/kg **Best For**: Further processing, flavoring, institutional cooking **Packaging**: PP bags, bulk packaging **Target Market**: Food processors, manufacturers ## Grading Process: Step-by-Step ### Stage 1: Visual Inspection **What to Check**: 1. Overall appearance (color, uniformity) 2. Presence of foreign matter 3. Visible damage or defects 4. Shape consistency **Sample Size**: - Minimum 500g sample from each lot - For large lots (>500kg), multiple samples from different sections

### Stage 2: Size Grading

**Equipment Needed**:
– **Manual**: Grading sieves (different mesh sizes)
– Cost: ₹5,000-15,000 for set
– Capacity: 10-20 kg/hour

– **Mechanical**: Vibrating screens, destoners
– Cost: ₹50,000-2 lakhs
– Capacity: 100-500 kg/hour

**Process**:
1. Pass through largest mesh (16mm) – retains Lawa
2. Pass through 12mm mesh – retains Murra
3. Pass through 10mm mesh – retains Samundi
4. Pass through 8mm mesh – retains Tukda
5. What passes through – Chatni

### Stage 3: Quality Parameter Testing

**Moisture Testing**:
– Use moisture analyzer
– Test random samples
– Document readings

**Breakage Assessment**:
– Count broken pieces in 100g sample
– Calculate percentage
– Repeat for accuracy

**Puffiness Check**:
– Visual inspection
– Cross-section 10 pieces
– Calculate percentage of well-popped

### Stage 4: Documentation

**Essential Records**:
– Lot number and date
– Size distribution percentages
– Moisture content
– Breakage percentage
– Overall grade assigned
– Photos (for reference)

### Stage 5: Segregation and Labeling

– Separate by grade
– Label clearly with grade and date
– Store separately to maintain grade integrity
