摘要 以海南山竹为材料,研究了不同贮藏条件对山竹果皮木质化及抑菌活性影响。结果表明:随着贮藏时间的延长,山竹果壳木质素沉积指标木质素含量和粗纤维含量均呈上升趋势。贮藏末期,常温处理的木质素含量比同期壳聚糖、海藻酸钠和低温处理的木质素含量分别增加6.0%、2.8%和14.3%。木质化底物总酚含量呈先升后降趋势,在第6天达到峰值,为33.033 mgGAE/g(鲜重),抑菌活性表明,在贮藏期间,山竹果皮抑菌活性因受木质化产物和多酚转化产物的影响有不同的变化趋势,低温和涂膜有助于抑菌活性稳态化。 In the paper, the effect of different storage conditions on the mangosteen pericarp lignin deposition and antibacterial activities were studied. The results showed that: lignin content and the crude fiber deposition indexes all increased with the storage time. At 15th day , lignin content of mangosteen pericarp under room temperature treatment were increased to 6% ,2.8% andl4.3% than that of chitosan, sodium alginate and low-temperature treatment. The total phenolic content of lignified substrate showed a trend of first increasing and then decreasing, and attained the max peak in 6d storage. Antibacterial capacity had different trend based on different compounds of lignification and phenolic during the whole storage. Low temperature and film coating can help to stabilize the bacteriostatic activity.
