Abstract

In this paper,the effect of fresh- keeping film on quality of P. eryngii were analyzed by principal component analysis method,and assessment model was established,by which the best packaging materials was screened.The results showed that 9 traits were consolidated into 2 principal components which accounted for83.203% of total variation. Comprehensive principal component analysis showed that the order of comprehensive quality of P. eryngii under different fresh- keeping film was LDPE > OPP > HDPE > PE > EVA > CK. Thus,the packaging film was conductive to mushroom preservation,and LDPE was the best for preservation.
