Storage

Watermelons are not adapted to long storage. Temperature management is important for optimum watermelon quality.

Watermelons store satisfactory at 15°C for up to 2 weeks. For long-term storage, the fruits should be kept at about 12°C and 85% RH.

At temperatures below 50°F, chilling injury can develop, causing decreased redness and juice leakage of the internal flesh, and surface pitting and Alternaria decay to the melon rind. Chilling will also cause discoloration in the internal flesh after the melon is warmed to room temperature if it was bruised before cold storage.

Holding watermelons for up to a week at room temperature can improve flavor and color. However, after several weeks at room temperature, they have very poor flavor and texture.
