Keeping Shiitake Fruiting Blocks Fresh During Export

Keeping shiitake fruiting blocks fresh during export depends on controlling temperature, humidity and ventilation to prevent heating, oxygen shortage or early pinning.

1. Pre-cool before shipping

Cool the blocks to the target temperature before dispatch to reduce field heat and metabolic activity.

2. Constant cold transport

Use constant cold transport at about -2 to -3°C and avoid frequent temperature fluctuations.

3. Temperature logger

Place a temperature logger with the shipment so the complete temperature record can be checked on arrival.

4. Arrival inspection

Check the temperature record first, then inspect packaging, firmness, damaged bags and early pinning.
