Summary

AFTER REVIEWING THE PRINCIPLES OF CONTROLLED-ATMOSPHERE STORAGE, THE AUTHOR DISCUSSES RECENT IMPROVEMENTS. HE DEALS SUCCESSIVELY WITH: THE CHOICE OF ATMOSPHERE (IN PARTICULAR ATMOSPHERES WHICH ARE LOW IN OXYGEN -LESS THAN 1. 5% -WHOSE USE, ADVANTAGES AND DISADVANTAGES ARE ANALYZED), THE ROLE AND CONTROL OF ETHYLENE AND THE SELECTION OF TEMPERATURE AND RELATIVE HUMIDITY. COMMENTS ARE THEN MADE ON SOME TECHNOLOGICAL ASPECTS: GAS-TIGHTNESS OF COLD ROOMS AND ITS MEASUREMENT, THE ABSOLUTE NECESSITY OF ACHIEVING THE CORRECT TEMPERATURE AND GAS COMPOSITION AS QUICKLY ASPOSSIBLE, THE PROCESSES FOR REMOVING ETHYLENE AND INNOVATIONS CONCERNING CONTROL AND STABILITY OF OXYGEN AND CO2 LEVELS (FOR INSTANCE ABSORPTION BY MOLECULAR SIEVE OR PERMEATION THROUGH POLYMER MEMBRANE).
