DISORDERS CAUSED BY SOME VOLATILES, OTHER THAN ETHYLENE, FOUND IN STORAGE ROOMS |

| Abstract:
With modern storing, packing, grading and transporting techniques the occurrence of a great number of acetates, alcohols, organic acids, aldehydes, ketones, hydrocarbons in the atm (atmosphere) around the product may increase. Some volatiles such as hexylacetate, hexanol, acetic acid, 2-heptanon and octane may at a high level of 100 to 1000 ppm deteriorate colour and consistency of sensitive horticultural products. The kind of fruit, degree of ripeness, structure of the epiderm, surroundings temperature are factors, which determine to an important degree the sensitivity of the product to volatiles. By means of laboratory gaschromatographic and mass spectrometric methods and also practical colour gas detectors, data were obtained about the nature of volatiles present in the atmosphere of stores. We now use activated charcoal to regulate the proper concentration of volatiles and perhaps in the future, new more efficient absorbents may become available. | |
