Abstract
Regulation of post harvest fruit metabolism enables to control the fruit storeability. Storage conditions include also very low oxygen conditions which may lead to anaerobic metabolism. Concentration of acetaldehyde, ethanol and ethyl acetate was monitored during anaerobic phase and afterwards during storage of fruit in air. Critical concentrations of acetaldehyde, ethanol and ethyl acetate were determined according to low oxygen disorders. Fruit maturity and storage temperature affects the accumulation of acetaldehyde, ethanol and ethyl acetate. Concentration of acetaldehyde dictates the appearance and severity of low oxygen disorders. The influence of exogenous ethanol or methanol and natural apple aroma compounds on the appearance of superficial scald was studied. Results are to be used in integral keeping of fruit quality by means of dynamic controlled atmosphere.
