Study on a Non-Destructive Method for Early Prediction of Onion Storability Using Odor Compounds

MNMana NakashimaYIYouichi IdeAHAkiko HURUTA

Key Points

  • The research aims to develop a non-destructive method for predicting the storability of onions during storage.
  • Conducted sensory evaluation of odors in onions upon storage.
  • Used gas chromatography to analyze volatile organic compounds.
  • Identified correlations between specific odors and storability issues.
  • Samples with a 'mold-soil' odor showed a higher tendency for storage rot.
  • Volatile organic compounds potentially enable prediction of storability.

Abstract

佐賀県産タマネギは，貯蔵中に腐敗が進行する“貯蔵腐敗”が問題となっている．本研究では，タマネギの入庫時に，貯蔵性の優劣を非破壊で“予測する技術”の構築を目的とした．嗅覚官能評価の結果，“カビ・土様”のにおいが感知された試料は貯蔵腐敗が発生しやすい傾向が観察された．ガスクロマトグラフ質量分析計による分析の結果，指標となる揮発性有機化合物によって，貯蔵性の優劣を予測できる可能性が示された．
