摘要

•Tracking changes of VOCs in trout and carp filets during storage using DHS-GC-TOFMS.•DHS analysis and sample preparation techniques were optimized.•Homogenization with water caused losses of 98 % in peak area of lipophilic VOCs.•Univariate and multivariate statistics led to selection of 37 spoilage markers.•60 % of markers were identified; plausibility check via literature was included.
