What is pre-cooling?

• A. A process that replaces the warm air in a box of flowers with refrigerated air
• B. A method of tinting flowers
• C. A method of removing ethylene
• D. A method to load sugars

Answer: (A)

Pre-cooling is the rapid cooling of harvested flowers to a low storage temperature to slow respiration and preserve quality. By circulating refrigerated air through or around the flowers, heat is removed quickly, lowering their temperature before they are stored or shipped. This is the option that best describes the process. Tinting flowers involves color changes, ethylene removal is about delaying aging without necessarily cooling, and loading sugars relates to nutrition, not temperature management.
