The aim of this work was to investigate the main
deterioration factor that badly affected the storage quality for the
low-temperature storage (4±1)℃ ofprunus
americana, and the comprehensive evaluation method ofprunus americanawith 1-Methylcyclopropene(1-MCP) treatment. Using the
prunus americanaas the experimental
material, the changes in fruit skin color, fruit firmness, soluble solid
content, content of titratable acid, reducing sugar, weight loss rate during
storage were investigated by one-way analysis. Combination of multiple
variables into a new and unrelated comprehensive index through
subordinate function and factor analysis to comprehensive
evaluation the storage quality ofprunus americanawith different concentration and handling time of 1-MCP treatment. The results
showed that skin color and fruit firmness are the main factors of determining
theprunus americanaquality. The
comprehensive evaluation model built by factor analysis revealed thatprunus americanatreated with 0.75 μL/L
1-MCP showed a better storability, and its preservation period could be prolong
for 16 days. In conclusion, this study used multivariate analysis method to
comprehensively evaluate comprehensive scores ofprunus americanawith 1-MCP treatment during storage, and clarified
the main deterioration factor that badly affected the storage quality, and
determined the proper concentration and time of 1-MCP treatment to preserve theprunus americana.
