Here’s a TESDA- and Oud Academia–aligned module on Storage Conditions (Humidity & Light Control) for agarwood leaf tea, focusing on food-grade, non-resin leaves, quality preservation, and export readiness.
Storage Conditions: Humidity & Light Control
Food-Grade Agarwood Leaf Tea
1. Core Principle
“Proper storage conditions preserve aroma, flavor, color, and bioactive compounds while preventing spoilage.”
Agarwood leaves are sensitive to humidity, oxygen, temperature, and light. Controlling these factors is essential for premium quality, consumer safety, and export compliance.
2. Humidity Control
| Parameter | Recommended Range | Impact on Tea Quality |
|---|---|---|
| Relative Humidity (RH) | 45–60% | Prevents mold growth, leaf clumping, and aroma loss |
| Leaf Moisture Content | <8–10% | Ensures microbial safety and optimal aroma preservation |
| Packaging Considerations | Airtight, moisture-barrier materials | Silica gel or clay desiccants can supplement |
| Monitoring | Hygrometer or moisture indicators | Verify RH in storage areas regularly |
Tip: Avoid storing tea in damp environments, near water sources, or areas prone to condensation.
3. Light Control
| Light Factor | Recommended Practice | Impact on Tea Quality |
|---|---|---|
| Sunlight / UV | Avoid direct exposure | UV degrades polyphenols, accelerates aroma and color loss |
| Ambient Light | Low or diffused lighting | Maintains aroma and prevents leaf bleaching |
| Packaging | Opaque or foil-lined bags, dark glass jars | Blocks light while adding moisture and oxygen barrier benefits |
Tip: Light exposure is especially critical for green leaves and functional blends.
4. Recommended Storage Practices
- Cool Environment: 15–25°C preferred; avoid heat sources
- Dry Conditions: Maintain RH 45–60% with moisture control measures
- Dark Storage: Minimize light exposure with opaque packaging or storage in cabinets
- Inventory Rotation: First-in, first-out (FIFO) to maintain freshness
- Traceability: Include batch number, harvest date, and packaging date on storage logs
5. TESDA-Aligned Learning Outcomes
Learners will be able to:
- Identify optimal storage conditions for agarwood leaf tea
- Monitor and control humidity and light exposure in storage areas
- Implement packaging and environmental measures to maintain quality
- Apply inventory rotation and traceability to preserve aroma, flavor, and safety
- Integrate storage control with shelf-life, sensory evaluation, and functional blends
6. Integration with Other Modules
- Moisture & Oxygen Barriers: packaging supplements environmental control
- Desiccants & Nitrogen Flushing: aids humidity and oxidation management
- Shelf-Life Testing: validates effectiveness of storage conditions
- Sensory Balance & Aroma Release: prevents aroma degradation over time
7. Regulatory & Export Notes
- FDA-PH and ASEAN require safe storage conditions to prevent contamination and spoilage
- Proper humidity and light control supports export-quality standards and premium branding
- Storage monitoring is part of traceability documentation
8. Training Disclaimer
This module applies exclusively to food-grade agarwood leaves.
Resin-based or medicinal products follow separate storage protocols.
✅ Ideal For:
- TESDA CBLM & storage management modules
- Oud Academia premium tea production, functional blends, and single-origin courses
- Plantation SOPs for harvested, dried, and packaged leaves
- Export-ready loose leaf, tea bag, and pyramid sachet products
I can next create:
- A visual infographic showing optimal storage conditions for humidity and light control for agarwood leaf tea
- A storage log template for monitoring temperature, humidity, and light exposure
- Integration into TESDA submission package with barrier packaging, desiccants, nitrogen flushing, and shelf-life modules
