The cold chain is the uninterrupted series of temperature-controlled storage and transport steps — from freezing or harvest through storage, loading, transport and delivery — that keeps a product within its specified temperature range. For frozen fruits and vegetables the standard requirement is −18 °C or colder. A broken cold chain causes quality loss, ice recrystallisation and food-safety risk, which is why buyers request temperature records for every shipment.
