Prickly pears

Harvesting and Handling

Prickly pear fruit are harvested from various species of the Prickly pear cactus. The fruit is a berry, and consists of a thick fleshy skin or rind surrounding a juicy pulp that contains many hard-coated seeds. Fruit vary considerably in colour, size and flavour.

Fruit of high quality need to be harvested near full-ripe to have colour and flavour typical of each variety. They should have a high percentage of pulp, a low content of seeds, and have a peel that is easy to remove. Stage of maturity or ripeness at harvest is very important for fruit quality since sugar content and sweetness do not increase after harvest. Maturity indices include: fruit size and fullness; change in peel colour, abscission of the small spines or glochids; fruit firmness; and flattening of the floral cavity or receptacle. Peel colour is the single most important index for commercial harvest.

Fruit are packed according to colour, size, and condition in single or double layer tray cartons. Large fruit may be wrapped in tissue paper to reduce scuffing and other physical injury. Fruit may also be packaged in cartons with perforated plastic liners to reduce water loss under dry storage conditions. Fruit can be bruised easily by finger compression during harvest, but damage to the stem-end is by far the most serious mechanical injury. High gloss fruit waxes are often used to improve visual appearance and reduce dehydration.

Cooling and Storage

Depending on variety, ripeness stage, and harvest season, fruit can be kept for 2 to 5 weeks at 5°C to 8°C with 90% to 95% RH. Factors limiting storage-life are decay, dehydration and chilling injury. Cactus pear fruit are especially chilling sensitive when stored at <5°C, but chilling injury may occur in some varieties at <10°C. Symptoms include pitting, surface bronzing and dark spots on the peel, and increased susceptibility to decay. Summer harvested fruit are more chilling sensitive than autumn-harvested fruit.

Mixed loads

Prickly pear fruit produce very low amounts of ethylene, and are not sensitive to ethylene exposure.


Limited research indicates holding cactus pears at 5°C in 2% O2 and 2% to 5% CO2 delays ripening and extends storage life.
