Green beans are among the most perishable vegetables Egypt exports, and they come with a twist: they are chilling-sensitive, so storing them too cold causes pitting and rusty spots. The window between ‘cold enough’ and ‘too cold’ is narrow, which is why pre-cooling speed and temperature control decide quality. This guide covers the green bean cold chain from harvest to reefer, plus packing formats.

Quick answer: Fresh Egyptian green beans are pre-cooled fast (forced-air or hydro-cooling) right after harvest and held at about 5–7°C at 90–95% RH — not near 0°C, because beans suffer chilling injury (pitting, russeting) below about 5°C. Shelf life is short (~1–2 weeks), so airfreight is common for premium fine beans. Packing is retail punnets (often topped-and-tailed) or bulk cartons (~4–5 kg); frozen beans are IQF at −18°C.

Pre-cool fast

Green beans respire quickly and lose quality within hours of picking, so Egyptian fresh-export beans are moved straight to forced-air or hydro-cooling to remove field heat fast. Rapid cooling preserves the crisp snap, fresh green colour and shelf life; any delay shows up as limp, dull beans on arrival.

The chilling-sensitivity rule

Unlike many vegetables, green beans are chilling-sensitive. Held below roughly 5°C, they develop pitting and rusty-brown spots (chilling injury) within days. The target is therefore a moderate chill — around 5–7°C at 90–95% RH — cold enough to slow respiration, warm enough to avoid injury. This is the single most important point to get right.

Packaging formats

  • Retail punnets / flow-wrap — fine beans, often topped-and-tailed, in 150–250 g packs for supermarkets.
  • Bulk cartons (around 4–5 kg) — whole beans for foodservice and wholesale.
  • Frozen — IQF whole or cut beans in retail bags or bulk cartons.

Beans are graded by width, handled gently to avoid bruising and snapping, and kept cool throughout packing.

Airfreight vs sea freight

Because fresh fine beans have such a short shelf life, airfreight is widely used to land premium beans in the UK and EU at peak quality. Sea reefer (at ~5–7°C) is used where transit time and cold-chain control allow, typically for bobby beans and shorter routes. Frozen beans always ship by reefer at −18°C.

Quality preservation checklist

  • Pre-cool fast (forced-air / hydro) within hours of harvest.
  • Hold at 5–7°C and 90–95% RH — never below ~5°C (chilling injury).
  • Use airfreight for premium fine beans; reefer where transit allows.
  • Handle gently to avoid bruising and snapping.
  • Freeze beans by IQF and hold steadily at −18°C.

Frequently asked questions

At what temperature should green beans be stored?

Around 5-7 degrees C at 90-95% humidity – not near 0 degrees C, because green beans are chilling-sensitive and develop pitting and rusty spots when too cold.

Why are green beans often airfreighted?

Their short shelf life means airfreight lands premium fine beans in the UK and EU at peak quality.

How are fresh green beans packed?

Fine beans in retail punnets or flow-wrap (often topped-and-tailed); whole beans in bulk 4-5 kg cartons.

How are frozen beans handled?

Individually quick-frozen (whole or cut) and held at minus 18 degrees C, shipped by reefer.

Why is fast pre-cooling so important?

Green beans respire quickly and wilt within hours; removing field heat fast preserves snap, colour and shelf life.
