Abstract:
In the paper, Hainan mangosteen was used as materials to study the effect of different storage temperature on hardening characteristic and antibacterial activities of mangosteen pericarp. The results showed that, lignin content and the crude fiber content of lignin deposition indicators of mangosteen shell all shows ascendant trend followed as the storage period extending. At the end of the storage, lignin content of mangosteen pericarp under room temperature treatment was increased 14.3% than that of low-temperature treatment. Total phenolic content of lignified substrate showed a trend of first increasing and then decreasing, and reached the max peak (33.03 mgGAE/g FW ) in a 6-day storage. Antibacterial capacity had different trend based on different products of lignification and polyphenol conversion products during the whole storage. Low temperature contributed to the stable of bacteriostatic activity.
