智能感官分析技术结合传统感官评价对细点圆趾蟹蟹肉制品品质特性研究

采用智能感官分析技术结合传统感官评价，研究了细点圆趾蟹蟹肉、细点圆趾蟹重组蟹肉、仿蟹肉块和仿蟹肉棒的感官品质。4类均为低脂类、可放心食用的食品。用电子舌技术与主成分分析法对4类蟹肉样品进行了区分和识别，用质构仪检测了4类样品的适口性（包括硬度、弹性、黏结性、胶性、咀嚼性和回复性）。结果表明，仿蟹肉制品与纯蟹肉在味道上存在明显差异，纯蟹肉较仿蟹肉制品具有更强的鲜味回味，但苦味、涩味和苦味回味相对较高；蛋白质类添加剂（TG酶）有利于提高纯蟹肉的感官品质，尤其可大幅度改良口感和质地，全质构分析测定结果与人的感官评价结果一致性较高。

Study on quality characteristics of crab meat products of Ovalipes punctatus by intelligent sensory analysis combined with traditional sensory evaluation

The sensory quality of Ovalipes punctatus, Ovalipes punctatus reconstituted crab meat products, crab meat pieces and crab sticks were studied by using intelligent sensory analysis technology combined with traditional sensory evaluation. The four types of products were all low-fat foods that can be eaten with confidence. The electronic tongue combined with the principal component analysis method was used to distinguish and identify the four types of crab meat products, and the palatability of various types of crab meat (including hardness, elasticity, cohesiveness, gumminess, chewiness, resilence). The results showed that there was a significant difference in taste between imitation crabmeat and real crabmeat. Compared with imitation crabmeat, real crabmeat had a stronger umami aftertaste, but the bitterness and astringency and miscellaneous taste were relatively higher; TGase had a positive effect on the sensory quality of crab meat, especially on its taste and texture, the whole texture measurement results and human sensory evaluation results showed good consistency.
