    Identification and Detection of Fungal Growth on Freeze‐dried Agaricus Bisporus using Spectra and Olfactory Sensors 

    Wang, Liuqing; Hu, Qiuhui; Pei, Fei; Mariga, Alfred Mugambi; Yang, Wenjian (Wiley Online Library, 2019)
    Fungal contamination in food products leads to mustiness, biochemical changes, and undesirable odors, which result in lower food quality and lower market value. To develop a rapid method for detecting fungi, hyperspectral ...
