中文摘要：本研究旨在探究壳聚糖肉桂酸包被的平铺白珠树叶精油(GPEO)微胶囊抗黄曲霉(EC-03)、黄曲霉毒素B1分泌及其作用方式的功效。结果表明壳聚糖基灌封材料提高了GPEO的抑菌功效及稳定性。
外文摘要：The present study was undertaken to investigate the efficacy of chitosan-cinnamic acid based micro encapsulated Gaultheria procumbens L essential oil (GPEO) against Aspergillus flavus (EC-03), aflatoxin B1 secretion and its mode of action. Scanning electron microscopy (SEM) and particle size analyzer analysis revealed that the microencapsulated GPEO exhibited an even spherical shape and particle size ranged between 7.00 and 90.0 gm. During chemical characterization (GC-MS), methyl salicylate (96.25%) was identified as the major component of GPEO. Microencapsulated GPEO exhibited strong antifungal and aflatoxin B1 suppressor activity than the uncapsulated GPEO and completely inhibited growth and toxin production at 1.00 mu L/mL. The mode of action of microencapsulated GPEO was elucidated targeting ergosterol content in the cell membrane, the release of cellular ion contents and morphological alteration in A. flavus. The results demonstrate the potential of chitosan-based encapsulating material for the improvement of the antimicrobial efficacy as well as stability of GPEO.
