摘　　要：目的研究不同处理工艺枸杞的显微特征变化,并加以甄别。方法采用荧光显微镜、体视显微镜和扫描电子显微镜,观察和比较处理前后枸杞果实的显微特征。结果食用碱处理可使枸杞果实表面的蜡质层溶解变薄或部分消失(非文献报道的蜡质层集聚或呈现裂隙现象),导致表皮的通透性增加,进而提高干燥速率;硫熏可使枸杞果实的膜结构解体破坏,细胞色素均匀释放于细胞中。不同加工方法对枸杞的显微结构有显著影响,其显微结构变化可用于甄别硫熏枸杞。结论为枸杞加工干燥方法的改进及枸杞加工方式的甄别提供了实验依据。OBJECTIVE To study the changes of microscopic characteristics of Lycium barbarum fruit under different treatment processes.METHODS In this study,fluorescence microscope,stereomicroscopy and scanning electron microscope were used to observe the change of microstructure from L.barbarum fruit between before and after treatment.RESULTS Edible alkali treatment could cause the surface wax layer of L.barbarum fruit to dissolve,thin,or partially disappear(not reported in literature as wax layer aggregation or cracking phenomenon),leading to an increase in epidermal permeability and thus increasing the drying rate.The membrane structure of L.barbarum fruit was disintegrated and destroyed,and cytochrome was released uniformly into the cells after sulfur fumigation.Different processing methods had significant effects on the microstructure of L.barbarum fruit.CONCLUSION This study can provide an important reference value for the improvement of processing and drying methods of L.barbarum fruit and the identification of processing methods of L.barbarum fruit.
