Temperature and Humidity Thresholds for Agarwood Storage and Rainy Season Countermeasures

The core temperature and humidity thresholds for agarwood storage are 18-25°C and 50%-65% relative humidity. During the rainy season, sealed storage with desiccants and dehumidifiers is essential. This article provides scientific principles and practical solutions.

Why Temperature and Humidity Are Critical for Agarwood

Agarwood is a composite of resin and wood fibers, and its aromatic components (sesquiterpenes, chromones, etc.) are highly sensitive to temperature and humidity changes. High temperatures accelerate the evaporation of volatile oils, while high humidity promotes mold growth and wood fiber swelling. Conversely, humidity below 40% causes shrinkage and micro-cracks. Therefore, maintaining 18-25°C and 50%-65% relative humidity is the golden range for long-term storage. This is also supported by the Agarwood Encyclopedia.

Scientific Basis and Monitoring Methods

Temperature threshold: Above 30°C, the vapor pressure of volatile components rises significantly, increasing aroma loss; below 10°C, molecular activity slows. Humidity threshold: Above 70% RH, mold spores germinate readily; below 45% RH, wood shrinks. Use a digital thermo-hygrometer for real-time monitoring. For high-value Kyara, keep humidity at 55%-60% and avoid temperature fluctuations.

Three Threats of the Rainy Season and Countermeasures

The rainy season (May-July) poses major challenges: mold, wood swelling, and aroma loss. Countermeasures: ① Sealed storage with food-grade desiccants (replace every two weeks); ② Use dehumidifiers to keep humidity below 60%; ③ Minimize opening of containers; ④ Inspect weekly for mold. For detailed operations, refer to Chinese Incense Studies · Agarwood Identification.

Container Selection and Placement

Use tin cans, glass jars, or food-grade plastic containers; avoid paper or wooden containers. Keep away from moisture sources and direct sunlight. For daily use, a constant temperature and humidity cabinet is recommended. If mold appears, isolate and consult a professional. See the Identification Pillar Page for more.

Key Takeaways

1. Temperature: 18-25°C; Humidity: 50%-65%.
2. Rainy season: prevent moisture, mold, and temperature fluctuations.
3. Sealing + desiccants + dehumidifier are core measures.
4. Regular inspection for early detection.
