What to Look For
Choose grapefruits that are glossy, round, smooth, and feel heavy for their size.
- 12°C - 14°C
- 90 - 95% Relative Humidity
Grapefruit will keep for 6-8 weeks in optimal conditions.
Grapefruits typically have coatings applied to prevent water loss. High-shine water waxes also help minimize chilling injury.
Chilling injury can occur at temperatures below 5°C. Symptoms include pitting, watery breakdown, and reddish-brown discolouration.
Response to Ethylene
Grapefruit is highly sensitive to ethylene. Exposure for as little as 1-3 days can cause the skin colour to change as well as make it more susceptible to decay.
