Abstract

This study was conducted to identify the effects of 1-MCP and the storage methods for maintaining the quality of asparagus spears. Asparagus spears treated 1-MCP stored in MA condition and perforated film (conventional condition) and 1-MCP non-treated used as control. The treated asparagus was stored at $4^{\circ}C$ for 40 days. The fresh weight loss rate was less than 0.2% in all MA (Modified atmosphere) storage treatments, including the 1-MCP treatment, and 1-MCP shown the less fresh weight loss rate in perforated film storage after 20 days storage. The carbon dioxide concentration within a package was 5-12% in MA storage, which is whith the tolerated range of maximum $CO_2$ content of asparagus spears in recommended CA or MA conditions. The oxygen content was maintained between 5 to 15% in MAP treatments. The ethylene content was lowest at the MA storage with 1-MCP treatment. Visual quality, off-flavor, soluble solid contents, and hue angle on the final storage day were higher in MA storage and the 1-MCP treatment and conventional MA storage did not show any significant differences. These results suggest that the 1-MCP treatment did not significantly affected the quality and storability of asparagus spears.

본 실험은 1-MCP처리와 저장방법이 아스파라거스의 신선도 유지에 미치는 영향을 알아보고자 수행하였다. 1-MCP 처리는 MA 조건과 유공필름(관행조건)에 처리되었으며 무처리구를 대조구로 사용하여 저장하였다. 처리된 아스파라거스는 40일 동안 $4^{\circ}C$에 저장되었다. 저장 중 생체중 감소율은 1-MCP 처리를 포함한, MA저장 처리구에서 0.2% 이하였고 유공필름에 저장된 1-MCP 처리는 생체중 감소율이 저장 20일 후부터 다소 낮아졌다. 포장 내 이산화탄소 농도는 MA저장 처리구 모두 최적 CA 조건인 5-12%($CO_2$)의 농도를 유지하였고, 산소농도는 5-15%를 유지하였다. 에틸렌 농도는 MA저장 1-MCP처리구가 가장 낮았다. 저장 최종일의 외관상 품질, 이취, 경도, 당도, 그리고 Hue angle 값은 MA저장에서 관행저장보다 우수하였으나 1-MCP처리간 차이는 없었다. 이상의 결과로 1-MCP처리는 아스파라거스의 품질 및 저장성에 영향을 미치지 않았다.
