Abstract

Abstract:

【Objective】 To explore the suitable pretreatment and drying methods by improving the utilization rate of leaves in the threshing process of Seabuckthorn branches,The findings provide theoretical basis and data support for the development and utilization of processing by-products of large fruit Seabuckthorn leaves in production. 【Methods】 In this study, Seabuckthorn leaves were used as test materials, and natural drying without pretreatment was used as control (CK). On the basis of systematically evaluating the drying effects of ultrasonic (CS) pretreatment, blanching (TP) pretreatment, ultrasonic+blanching (CS+TP) pretreatment and osmotic dehydration (ST) pretreatment on Seabuckthorn leaves, combined with natural (ZR) drying, hot air (RF) drying, microwave (WB) drying and vacuum freezing (LD) drying methods, the effects of different pretreatment combined with drying methods on the drying efficiency and bioactive substances of Seabuckthorn leaves were investigated. 【Results】 The results showed that the effect of CS pretreatment was significant after natural drying of Seabuckthorn leaves with different pretreatments. CS pretreatment combined with ZR, RF, WB and LD drying had significant effects on the drying efficiency and bioactive substances of H.rhamnoides leaves. Among them, CS pretreatment combined with RF drying method had the best effect, which could shorten the drying time of H.rhamnoides leaves by 4 times compared with CK, and meanwhile maintained the contents of total flavonoids, total phenols, proteins, polysaccharides and quebrachitol at 41.07, 29.56, 30.66, 3.53 and 22.14 mg/g, respectively. 【Conclusion】 Using CS pretreatment and RF drying method for large-scale utilization pretreatment of large fruit seabuckthorn leaves.

摘要：

【目的】提高大果沙棘枝条果脱粒过程中叶子的利用率,探寻其适宜的预处理及干燥方式,为生产中大果沙棘叶的产业化开发利用提供理论依据和数据支撑。【方法】以大果沙棘叶为试材,以不经预处理直接自然干燥为对照(CK),在系统评价超声(CS)预处理、烫漂(TP)预处理、超声+烫漂(CS+TP)预处理和渗透脱水(ST)预处理对其干燥效果基础上,结合自然(ZR)干燥、热风(RF)干燥、微波(WB)干燥和真空冷冻(LD)干燥方式,探究不同预处理结合干燥方式对沙棘叶干燥效率及生物活性物质的影响。【结果】大果沙棘叶经不同预处理自然干燥后,CS预处理效果较显著;CS预处理结合ZR、RF、WB和LD干燥对大果沙棘叶干燥效率和生物活性物质均有显著影响,其中CS预处理结合RF干燥方式效果最佳,可使大果沙棘叶干燥时间较CK缩短4倍,其中总黄酮、总酚、蛋白质、多糖和白雀木醇含量分别维持在41.07、29.56、30.66、3.53和22.14 mg/g。【结论】采用CS预处理RF干燥方式对大果沙棘叶进行规模化加工利用前处理。
