The previous termshelfnext termprevious termlifenext term of previous termmushroomsnext term packaged using previous termdifferentnext term polymer top-previous termfilmsnext term (PVC, PET with previous termdifferentnext term levels of perforations) was investigated using previous termhyperspectralnext termprevious termimagingnext term (HSI). Packaged previous termmushroomsnext term were previous termstorednext term at 4 ± 0.2 °C for 14 days and weight loss, Hunter L, a, b values, maturity index and in-pack gas composition (% CO2 and O2) were also measured. The results obtained showed that the PET film perforated with small holes (1 mm in diameter) was generally superior in terms of maintaining overall previous termmushroomnext term quality. Regression models were built to correlate HSI data with measured quality parameters. Prediction maps were generated from previous termhyperspectralnext term data to show the model performance at pixel level. Results presented in this work show previous termhyperspectralnext termprevious termimagingnext term can be used to evaluate the effect of previous termdifferentnext termprevious termpackagingnext term systems on previous termmushroomnext term quality and that perforated PET previous termpackagingnext term film is a viable alternative to the conventional PVC previous termpackagingnext term, facilitating an increase in previous termshelfnext termprevious termlifenext term from 10 to 14 days.
