Cut size & particle uniformity

Here’s a TESDA- and Oud Academia–aligned module on Cut Size & Particle Uniformity for Agarwood Leaf Tea, designed for food-grade, non-resin leaves, with practical guidance for quality control, processing, and export readiness.


Cut Size & Particle Uniformity

Food-Grade Agarwood Leaf Tea


1. Core Principle

“Uniform leaves brew consistently, taste predictably, and look premium.”

Particle size and uniformity affect:

  • Infusion quality – aroma, flavor, color
  • Drying efficiency – even moisture removal
  • Packaging & aesthetics – consumer perception
  • Regulatory & export compliance – batch consistency

2. Recommended Cut Sizes

Tea TypeCut Size / Leaf FormatNotes
Whole Leaf / Large4–6 cmPremium loose-leaf tea; gentle handling preserves aroma
Broken Leaf1–3 cmSuitable for convenient brewing; slightly faster infusion
Fannings / Small Pieces<1 cmUsed for tea bags; faster infusion but lower visual appeal

Training Tip: Keep consistent cut sizes per batch; avoid mixing very large and very small pieces.


3. Particle Uniformity Guidelines

  1. Sorting & Sieving
    • Use graded sieves or mesh trays to separate particle sizes
    • Remove dust, stems, and foreign matter
  2. Cutting Tools
    • Use sanitized scissors, knives, or mechanical cutters
    • Avoid crushing or powdering leaves unintentionally
  3. Batch Consistency
    • Maintain cut-size uniformity per batch
    • Record in batch log for traceability
  4. Impact on Infusion
    • Uniform leaves → even extraction of polyphenols and flavonoids
    • Non-uniform leaves → uneven color, taste, and aroma

4. Quality Assessment Benchmarks

ParameterIdeal Outcome
Leaf length / sizeConsistent within chosen grade (whole, broken, or fannings)
Leaf shapeIntact, minimal tearing or powdering
AppearanceEven color, no excessive dust or small fragments
SensoryUniform aroma and infusion color

5. TESDA-Aligned Learning Outcomes

Learners will be able to:

  1. Apply cutting and sieving techniques for uniform particle size
  2. Understand the impact of particle size on infusion quality and bioactive retention
  3. Maintain batch consistency and documentation
  4. Conduct visual and sensory evaluation for uniformity
  5. Integrate particle size standards with drying, oxidation, and packaging

6. Integration with Other Modules

  • Drying Methods: uniform size ensures even drying
  • Moisture Content: smaller pieces dry faster; adjust drying time
  • Functional Blends: maintain uniform particle size across blended herbs
  • Single-Origin Teas: preserve consistency for traceability and premium branding

7. Regulatory & Export Notes

  • FDA-PH and ASEAN: particle uniformity contributes to consumer safety, brewing consistency, and quality assurance
  • Labeling & Packaging: visually consistent teas improve marketability and premium appeal

8. Training Disclaimer

This module applies exclusively to food-grade agarwood leaves.
Resin and heartwood follow separate particle size and processing standards.


✅ Ideal For:

  • TESDA CBLM & quality control modules
  • Oud Academia leaf tea processing, blending, and packaging courses
  • Plantation SOPs for cutting, drying, and packaging consistency
  • Export-ready premium leaf tea production

I can next create:

  1. A visual infographic showing cut size ranges, leaf grades, and sieving workflow
  2. A batch log template for particle size and uniformity checks
  3. Integration into TESDA submission package with drying, oxidation, moisture, and sensory modules
