A hormone spray and cold pre-treatment keep wax apples firm in storage
Postharvest Storage
The mealy, bruised texture that ruins refrigerated tropical fruit like wax apple comes down to cell walls breaking apart in the cold, and this simple pre-treatment could mean less spoiled fruit reaching your table.
Wax apples are tropical fruit that get damaged by refrigeration, turning mushy and brown, a problem called chilling injury. Researchers found that briefly exposing the fruit to cold, then treating it with salicylic acid, a natural compound plants use to signal stress, kept the fruit's cell walls and membranes intact so it stayed firmer and fresher during cold storage.
Key Findings
Combined cold shock and salicylic acid treatment reduced chilling injury symptoms in wax apple compared to untreated fruit
The treatment preserved cell membrane integrity, limiting electrolyte leakage typically caused by cold damage
Cell wall structure was better maintained, helping fruit retain firmness during postharvest cold storage

Combining a brief cold shock with a natural plant hormone spray helps wax apples survive refrigerated storage without the mushy, damaged texture that cold usually causes, by keeping fruit cell walls and membranes intact.
