The controlled atmosphere technology (AC) is used in cold quarters for the storage, or in containers for the transport, of vegetables and fruits products. This technique stabilizes the atmosphere that surrounds the product in precise percentage with relation to the present O2 and CO2 in her, depending on the vegetal variety to control. For the avocado (American Persea) like climacterical fruit and concretely for the Hass variety, product of world-wide export, the conservation in AC is innovating for the maintenance of its optimal quality.
