Abstract
|
|
|
This experiment was conducted to observe the changes of composition of atmosphere in storage room by controlled ventilation under normal and sub-atmospheric conditions, and the biochemical changes in apple texture under these conditions. The results were as follows;
1) By controlled ventilation, concentration of carbon dioxide in storage room was optionally regulated and constantly maintained.
2) Among compositions of internal atmosphere of apple, especially, concentration of ethylene was much decreased at apple stored under sub-atmospheric condition than that stored under normal atmospheric condition.
3) Acidity of apple stored under sub-atmospheric condition was much greater than that of apple stored under normal atmospheric condition.
4) Respiratory quotients of apple, which was stored under normal and sub-atmospheric conditions, were shown to be high. But decarboxylation of added pyruvate was found more active in slices prepared from apple stored under sub-atmospheric condition.
