摘　　要：[目的]研究中草药结合涂膜保鲜技术对草莓保鲜的效果。[方法]以可食性的壳聚糖、纳米氧化硅,以及甘油、单甘脂等为材料,制出一种可食性的草莓保鲜膜,并将鹿蹄草、黄芩、黄柏、半边莲、北豆根5种中草药的单一或组配制剂中保鲜防腐效果最佳的组配进行前期处理。通过腐败率、感官评价等指标判断其对草莓的保鲜效果。[结果]试验表明,壳聚糖-纳米氧化硅保鲜涂膜与鹿蹄草水煎液能够显著抑制青霉、灰霉的繁殖,该处理对草莓有较好的抑菌保鲜作用,能够使常温下"丰香"草莓的保鲜期达到5 d。[结论]研究可为目前市场上草莓的常温保鲜提供参考依据。[Objective] To study fresh-keeping effect of Chinese herbs combing with coating technology on strawberry.[Method] With edible chitosan,nano silica,glycerol,monoglyceride as materials,a kind of edible strawberry plastic wrap was made.Early treatment was conducted on five kinds of Chinese herbal medicine wintergreen,baicalin,Cortex Phellodendri,lobelia,Rhizoma Menispermi in single or group of formulation of preservation and antisepsis effect.The fresh-keeping effect of strawberry was judged by decay rate,sensory evaluation index.[Result] The experimental results showed that the chitosan-nano silica preservation coating and wintergreen water extract can inhibit the propagation of Penicillium,gray mold,the processing of strawberry has better antibacterial fresh-keeping effect,can make the room temperature＂ Toyonoka strawberry＂ preservation period up to 5 days.[Conclusion] The study can provide reference basis for normal temperature preservation of strawberry.
