Abstract

A standard method to treat fruits with 1-methylcyclopropene (1-MCP) is to close the fruits for a relatively long time with the 1-MCP gas at the atmospheric pressure so that the gas diffuses into the fruits. In this study, 1-MCP gas was vacuum-infiltrated into the tomato fruits within a short time and the treatment efficiency was evaluated by measuring the changes of respiration and ethylene production rates. By the forced infiltration of 1-MCP, respiration rate was reduced proportional to the treated 1-MCP concentrations and inversely proportional to the applied vacuum pressures. But the 1-MCP treatment increased ethylene production, especially under the vacuum pressure of 60 mbar. At 120 mbar vacuum pressure the 1-MCP was efficiently infiltrated into the fruits. However an increase in concentration of 1-MCP was required to acquire the same level of effect as standard treatment method, presumably because of the increased ethylene production.

과실에 1-MCP를 처리하는 관행적인 방법은 대기압의 밀폐 조건에서 확산에 의해 과실 내부로 1-MCP를 침투시키는 방법이다. 본 연구에서는 1-MCP를 과실 내부 조직에 수분 이내에 강제 침투시키는 진공 침투 방법을 이용하여 토마토 과실에 1-MCP를 단시간 동안 처리한 후 에틸렌 생성과 호흡량의 변화를 분석하였다. 1-MCP의 강제 침투 처리에 의해 저장 초기 과실의 호흡이 억제되어 120mbar 내외의 진공압을 이용하면 1-MCP를 조직 내에 효율적으로 침투시킬 수 있을 것으로 판단되며 그 이하의 진공압 조건에서는 에틸렌의 생성이 증가하는 경향을 보였다. 그러나 1-MCP의 강제 침투 처리에 의해 에틸렌 생성량은 증가하였으며 관행적인 밀폐 처리와 동일한 수준의 처리 효과를 얻기 위해서는 보다 높은 농도의 1-MCP가 요구되는 것으로 나타났다.
