摘要: 以银杏果主栽品种‘大佛指’为试材,分别采用不同浓度的1-甲基环丙烯(1-MCP)熏蒸、纳他霉素喷涂以及壳聚糖浸泡处理银杏果,研究其在0 ℃冷藏后贮藏品质的质构变化。结果表明:壳聚糖浸泡处理可缓解银杏果贮藏中水分的散失,经纳他霉素处理可降低银杏种仁霉变率,使用1-MCP处理可保持淀粉含量在较高水平; 应用质构仪质地多面分析法(TPA)及穿刺下压破碎试验对贮藏后银杏果进行质构测试,得出500 mg/L纳他霉素可有效保持银杏果贮藏后的质地,3种保鲜剂分别在1.0%壳聚糖、0.5 μL/L 1-MCP、500 mg/L纳他霉素处理时,可有效保持银杏果贮藏品质,延长贮藏时间。

Abstract: As the ‘Buddha’ varieties of Ginkgo biloba fruits for test material, the effects of different concentration of preservatives(1-MCP, Natamycin, Chitosan)on the quality and texture of Ginkgo fruits were investigated during storage at 0 ℃ in this paper. The results showed that the water content of Ginkgo fruits soaked in Chitosan solution was increased, and the mildew rate of kernels was decreased treated by Natamycin. The content of the starch were maintained in higher level treated by 1-MCP. The results of using texture profile analysis with the texture analyzer showed that cohesiveness, chewiness,resilience might give reliable values in respect of texture properties of Ginkgo fruits. The puncture test was applied in the texture detecting of firmness of Ginkgo fruits. Ginkgo fruits treated with 1.0% CTS, 0.5 μL/L 1-MCP, 500 mg/L Natamycin could keep better storage quality and longer storage life than other preservatives.
