Dates

The date trade uses stage names drawn from Arabic that have become the international vocabulary of the commodity. In the khalal stage the fruit has reached full size and colour but remains firm and crisp, and it is sold as a fresh fruit in producing regions and eaten much like an apple. In the rutab stage it has begun to soften and darken from the tip, and it is a genuinely perishable soft fruit. In the tamr stage it is fully ripe, dark, and dense, and it keeps for a very long time.

Khalal

Full-size, fully coloured, still firm and crisp. Traded fresh, largely within producing regions, and handled as a perishable.

Rutab

Partly softened and darkened. A short-lived, high-value fresh product usually refrigerated or frozen for transport.

Tamr

Fully ripe, soft or semi-dry, sugar-dense. The stage that dominates international trade because it keeps and ships.

Dates are non-climacteric and ripen on the palm. A bunch does not ripen evenly, so harvesting is done in several passes — strands or individual fruit taken as they reach the intended stage — which makes date harvest labour-intensive and repetitive. All of it happens at height, from ladders or platforms, which shapes the economics as much as the biology does.

Fruit intended for the tamr stage may be left on the palm until it reaches it naturally, drying in place in the hot, arid climate that date production depends on. Where rain or humidity threatens the crop at that stage, or where the market wants a specific texture, fruit is picked earlier and its ripening and drying completed under controlled conditions — a controlled continuation of a process that would otherwise happen on the tree.

Keeping behaviour follows the stage directly. Khalal and rutab dates are perishable and require refrigeration or freezing; rutab in particular is often frozen for transport and thawed for sale, which is unremarkable in the date trade and would be unusual anywhere else. Tamr dates are stable at ambient temperature for extended periods, and refrigeration is used to preserve texture and colour and to control insects rather than to prevent spoilage.

The dominant storage problem for tamr dates is insects rather than microbes: sugar-rich stored fruit attracts stored-product pests, and infestation is a leading cause of loss and rejection. The trade addresses this with cold storage, hygiene, and controlled or modified atmospheres, with permitted treatments varying by market. Sugar crystallisation, darkening, and syrup leakage are quality changes that occur during storage without making the fruit unsafe.

Grading assesses cultivar and stage conformity, fruit size, colour, texture, skin condition, and freedom from defects, insects, and foreign matter. Skin separation — where the skin lifts away from the flesh — and darkening are common downgrades that are cosmetic rather than safety issues. Because the fruit is often handled directly and sold with minimal processing, cleanliness and freedom from infestation carry heavy weight in the specification.

• Insect infestation and insect damage in stored fruit
• Skin separation and puffiness
• Sugar crystallisation and syrup leakage
• Darkening and loss of characteristic colour during storage
• Souring and fermentation in fruit exposed to moisture at the softer stages
• Immature, unripened, or damaged fruit in the lot

Dates are eaten as fruit — the whole fruit, at whichever stage the market prefers, is by far the dominant use, and in the producing regions the commodity carries cultural and seasonal significance that supports a premium fresh trade in rutab and khalal that never leaves the region. Processing takes lower grades and surplus into paste, syrup, and pieces for baking and confectionery, and the pitted, paste, and syrup streams give date processors an outlet for fruit that cannot be sold whole.

• Food — whole dates at the traded stage, the dominant use
• Food processing — paste, syrup, and chopped fruit for bakery and confectionery
• Feed — surplus, damaged, and low-grade fruit used locally in livestock rations
