中文摘要:

      目的 为研究不同质量浓度黄芩提取物处理对百香果采后贮藏保鲜品质的效果，以期延长百香果贮藏时间。方法 以百香果为原料，黄芩提取物为保鲜剂，蒸馏水浸泡为对照，使用不同质量浓度黄芩提取物对百香果进行浸泡处理并置于室温贮藏(温度为18~23 ℃)。检测不同质量浓度黄芩提取物对百香果果实品质指标的影响，总结黄芩提取物最佳保鲜质量浓度以及贮藏保鲜效果。结果 在室温条件下，与对照处理相比，不同质量浓度黄芩提取物处理均能起到贮藏保鲜的效果。CK组的百香果在贮藏17 d后质量损失率为24.67%，硬度为6.31 kg/cm²，可溶性固形物含量为10.45 mg/g，而黄芩提取物处理B组(12.5 mg/mL)的百香果在贮藏17 d后质量损失率为17.60%、硬度为8.29 kg/cm²、可溶性固形物含量为12.84 mg/g，CK组与黄芩提取物处理B组(12.5 mg/mL)之间各指标呈显著性差异(P<0.05)。B组(12.5 mg/mL)黄芩提取物在保持百香果果实硬度、质量损失率、可溶性蛋白质、可溶性糖和维生素C等外在及内在品质指标的稳定均不同程度优于CK组和其他质量浓度黄芩提取物处理组。结论 在百香果室温贮藏保鲜中，采用质量浓度为12.5 mg/mL的黄芩提取物处理可以减少果实营养物质消耗，保持较好的果实品质。

英文摘要:

      The work aims to study the effect of different mass concentrations of Scutellaria baicalensis Georgi extract treatment on the postharvest storage and preservation quality of passion fruit, so as to prolong the storage time of passion fruit. With passion fruit as raw material, Scutellaria baicalensis Georgi extract as preservative, distilled water as control, passion fruits were soaked with Scutellaria baicalensis Georgi extract of different mass concentrations and stored at room temperature (18~23 ℃). The effects of different mass concentrations of Scutellaria baicalensis Georgi extract on the quality index of passion fruit were detected, and the optimal concentration and storage & preservation effect of Scutellaria baicalensis Georgi extract were summarized. At room temperature, compared with the control treatment, different concentrations of Scutellaria baicalensis Georgi extract could have the effect of storage and preservation. The weight loss rate of passion fruit in the control group was 24.67%, the hardness was 6.31 kg/cm2, and the soluble solids content was 10.45 mg/g after 17 days of storage, while the weight loss rate of passion fruit in the Scutellaria baicalensis Georgi extract treatment group B (12.5 mg/mL) was 17.60%, the hardness was 8.29 kg/cm2, and the soluble solids content was 12.84 mg/g after 17 days of storage. There were significant differences (P<0.05) between the control group and the Scutellaria baicalensis Georgi extract treatment group B (12.5 mg/mL). Group B (12.5 mg/mL) of Scutellaria baicalensis Georgi extract was better than that of the control group and other treatment groups in maintaining the stability of external and internal quality indexes such as hardness, weight loss rate, soluble protein, soluble sugar and vitamin C of passion fruit. In the room temperature storage and preservation of passion fruit, the treatment of Scutellaria baicalensis Georgi extract with a mass concentration of 12.5 mg/mL can reduce the consumption of fruit nutrients and maintain better quality of fruits.
