Abstract
Aroma attribute and aroma compound (AOC) composition of fresh-cut flower mushrooms under different static magnetic field (SMF) intensities (2 mT, 4 mT, 6 mT, and 8 mT) were evaluated via coupling aroma sensory assessment and headspace-gas chromatography-ion mobility spectrometry with principal component analysis and partial least squares-relationship analysis. Results showed that aroma quality was severely loss after dicing treatment. A total of 43 AOCs were identified from flower mushrooms, and 3-octanone was the predominant compound. Application of 2 mT SMF maintained more acceptable raw mushroom-like, earthy/musty, and almond-like/roasted, and cooked cabbage-like aroma attributes of diced samples, related to maximally retaining the contents of the key AOCs (i.e. 3-octanone, 2-methylbutanal, and dimethyl trisulfide). These findings could provide a technical reference and theoretical basis for improving the aroma quality of fresh-cut mushrooms via magnetic fields and explain the mechanism of aroma enhancement.
