Abstract EN
Effects of 1-methylcyclopropene (1-MCP) and vacuum precooling on quality and antioxidant properties of blackberries (Rubus spp.) were evaluated using one-way analysis of variance, principal component analysis (PCA), partial least squares (PLS), and path analysis.
Results showed that the activities of antioxidant enzymes were enhanced by both 1-MCP treatment and vacuum precooling.
PCA could discriminate 1-MCP treated fruit and the vacuum precooled fruit and showed that the radical-scavenging activities in vacuum precooled fruit were higher than those in 1-MCP treated fruit.
The scores of PCA showed that H2O2 content was the most important variables of blackberry fruit.
PLSR results showed that peroxidase (POD) activity negatively correlated with H2O2 content.
The results of path coefficient analysis indicated that glutathione (GSH) also had an indirect effect on H2O2 content.
