Summary

Apple is the most consumed fruit worldwide. It is harvested in both hemispheres and represents a high volume of trade throughout the year. Considering the competition, its quality should be irreproachable. During many years, cold-rooms atmosphere composition control (02 and CO2 = 2%) allowed for the doubling of shelf-life times without any unacceptable physiological disorders. A chemical treatment, sometimes used at the beginning of the storage, makes it possible to limit scalding. But today, pesticides have a bad reputation: more sustainable treatments were saught. Among them, treatments based on physics such as Ultra-Law Oxygen (02 = 1 %) were designed, and going to the extreme, a "02 stress deprivation " was induced at the beginning of the ULO preservation. This last process is called dynamic-controlled atmosphere. Because of the extreme accuracy required for the control process, the practical penetration of this process, designed 10 years ago in Canada, is relatively slow, mainly in the USA and Italy: 300.103 tons are preserved in these conditions. Such a process needs not only a high performance atmosphere control system but also, a very well trained operator. With this aim in view, ctiff, concerned about transferring a new technology in the best conditions, gathered an experimental network on the national scale, with district stations and professional partnerships. The first results are situated between classical controlled atmosphere and controlled atmosphere with initial chemical treatment.
