Stone fruit is delicious but demanding: it bruises at a touch, it ripens after harvest, and held at the wrong temperature for too long it can develop internal breakdown — the dry, mealy “woolliness” that ruins eating quality. The cold chain is therefore about the right harvest maturity, rapid cooling and gentle handling. This guide covers the stone-fruit cold chain and packing.

Quick answer: Stone fruit is climacteric (ripens after harvest) and bruise-prone. It is picked at the right maturity, cooled rapidly after harvest, and held cold near 0°C at high humidity to slow ripening — managed carefully, because intermediate temperatures held too long cause internal breakdown (“woolliness”). Shipped by reefer, or airfreight for premium early fruit. HS: apricots 0809.10, peaches/nectarines 0809.30, plums 0809.40.

Maturity, then speed

Because stone fruit ripens after harvest, it is picked firm-mature at a stage matched to the journey — firmer for sea freight, riper for premium airfreight. Then it is cooled rapidly to remove field heat, which is critical: slow cooling shortens life and raises the risk of breakdown.

The woolliness risk

Stone fruit (especially peaches and nectarines) can suffer internal breakdown — mealy, dry, “woolly” flesh — when held in an intermediate temperature range for too long. The defence is to cool fast and hold the fruit cold, close to 0°C, moving it through the danger zone quickly. Controlled-atmosphere storage can help on longer journeys.

Gentle packing

Stone fruit is packed to protect against bruising — typically single-layer trays with cup liners or pads, sometimes individually placed. Fruit is graded by size and colour and checked for firmness and freedom from blemishes.

Packaging formats

  • Single-layer trays with cup/pad liners for peaches, nectarines and apricots.
  • Punnets for retail (apricots, plums).
  • Cartons for plums and firmer fruit.

Quality preservation checklist

  • Pick at the right maturity for the journey.
  • Cool rapidly after harvest — do not delay.
  • Hold cold (~0°C) at high humidity; move through the danger zone fast to avoid woolliness.
  • Pack gently in single layers; grade by size and colour.
  • Ship by reefer (CA on longer routes); airfreight premium early fruit.

Frequently asked questions

Why is stone fruit cooled so quickly?

Rapid cooling preserves quality and reduces the risk of internal breakdown.

What is woolliness?

Internal breakdown – dry, mealy flesh – that develops when stone fruit is held at intermediate temperatures too long.

At what temperature is stone fruit stored?

Cold, near 0 degrees C, at high humidity, having been cooled rapidly first.

How is stone fruit packed?

Mostly in single-layer trays with liners to prevent bruising, plus punnets and cartons.

Is stone fruit airfreighted?

Premium, early fruit often is; the rest moves by reefer, sometimes with controlled atmosphere.
