Abstract:

In this paper, the effect of different packaging films on quality of Agaricus bisporus were analyzed by principal
component analysis (PCA) method, and an assessment model was established to screen the best packaging material. The
results showed that 9 traits were consolidated into 2 principal components, which accounted for 86.224% of the total
variance. The PCA showed that the order of the quality of A. bisporus under different packaging films was HDPE > LDPE >
OPP > LLDPE > EVA > control check (CK). Thus, all these packaging films were conductive to mushroom preservation,
and HDPE was the best one. These findings can provide scientific and intuitive evidence for quality evaluation.

Key words: Agaricus bisporus, packaging film, principal component analysis, quality, evaluation
