娄地青霉和纳地青霉对发酵鸭肉制品理化特性和微观结构的影响
Journal of Zhengzhou University of Light Industry(Natural Science Edition)（2022）
Abstract
以娄地青霉和纳地青霉为发酵菌株发酵鸭肉制品,研究这两种霉菌对发酵鸭肉制品理化特性和微观结构的影响.结果表明:发酵后期,与娄地青霉鸭肉制品相比,纳地青霉发酵鸭肉的硬度和弹性均较低,后发酵阶段的黏性更大,表面结合水含量较少且更为平滑;两种发酵鸭肉制品均无肌原纤维结构,且蛋白质二级结构中α-螺旋减少、β-折叠增多;纳地青霉发酵产生的挥发性风味物质较娄地青霉多,且产生了新的醛类和醇类物质,即纳地青霉更适宜作为发酵菌株用于发酵鸭肉制品生产.
