This experiment was conducted to observe the effect of subatmospheric pressure storage on the coloration of tomato fruits. Tomato fruits(Lycopersicon esculentum Kang Lyuk Misu), which were cultured on field, were havested at the mature green stage on June 16, 1976 and stored 10℃ under normal atmospheric pressure (NAP) and sub-atmospheric pressure (SAP). Furthermore, the treatment at SAP was subdivided into CO_(2) 0%(SAP-O), CO_(2) 5% (SAP-5) and CO_(2) 10%(SAP-10) concentration, respectively. The results obtained were as follows : The chlorophyll content was rapidly decreased for 10 days, whereas the content of chlorophyll in SAP treatment was retained 2㎎% after 40 days. The lycopene content in NAP-5 was 5㎎% after 20 days. On the other hand, that in SAP-10 was 3㎎% art after 40 days. The red color development was retarded for 30 days in SAP-10. Comparing with the formation of lycopene, that of carotene was less inhibited by storage conditions (carbon dioxide, temperature, pressure) and increased more slightly in SAP than in NAP. The ripening of tomato fruits in NAP was retarded for about 30 days as compared that in SAP. The intensity of respiration in SAP was weaker than that in NAP. Also the peak of respiration in SAP was delayed compared to that of NAP. The content of reducing sugar and titratable acidity in SAP were retained more than in NAP up to 30 days tested.
