摘　　要：为解决冷鲜马肉在贮藏过程中发生汁液流失,导致冷鲜马肉发生腐败变质的问题,该研究通过静电纺丝技术,制备出单向输水抑菌垫并应用于冷鲜马肉的保鲜实验中。通过扫描电镜、傅里叶红外光谱、缓释性能、单向输水性能和抗菌性能评价该抑菌垫对冷鲜马肉的保鲜效果。结果表明,百里香酚被成功包埋于上层纤维膜中并且具有缓释作用,对大肠埃希氏菌、金黄色葡萄球菌具有明显的抑菌效果[抑菌圈直径为(24.32±0.72)mm],水可以自发地从疏水层到达亲水层并且被吸收。将该抑菌垫应用于冷鲜马肉的贮藏实验中,单向输水抑菌垫对于马肉中菌落总数值、挥发性盐基氮(total volatile basic nitrogen,TVB-N)值的上升均具有明显地延缓作用,并且可以将马肉货架期延长6 d。该抑菌垫可以控制微生物生长繁殖所需水分并抑制微生物繁殖,因此,该抑菌垫可以有效延长冷鲜肉的货架期,为冷鲜肉的贮藏保鲜提供了一种新的方向。This study aimed to solve the problem of juice loss during storage,which could lead to spoilage of cold fresh horse meat.By electrostatic spinning technology,one-way water transfer antibacterial pads were prepared and applied to the cold horse meat preservation experiments.The effect of the pad on the preservation of cold horse meat was evaluated by scanning electron microscopy,Fourier infrared spectroscopy,slow-release performance,one-way water transfer performance,and antibacterial performance.Results showed that thymol was successfully encapsulated in the upper fibrous membrane and had a slow-release effect.It has a significant antibacterial effect on Escherichia coli and Staphylococcus aureus[diameter of inhibition circle was(24.32±0.72)mm].Water can spontaneously reach the hydrophilic layer from the hydrophobic layer and be absorbed.In the storage experiment of cold fresh horse meat,the one-way water transfer pad had a significant delaying effect on the increase of total colony value and TVB-N value in horse meat,and could extend the shelf life of horse meat for 6 days.The pad can control the water required for microbial growth and reproduction and inhibit microbial reproduction,therefore,the pad can effectively extend the shelf life of cold meat,which provides a new direction for the storage and preservation of cold meat.
