基于双网络策略改善冷冻鱼糜凝胶冻融品质
Improving the Freeze-thaw Quality of Frozen Surimi Gel Based on the Dual Network Strategy
摘要
Abstract
Given to the quality deterioration,nutrients loss and the reduction of processing characteristics of frozen surimi gels,the present study was conducted to prepare surimi gels with a dual-network microstructure based on the TGase-induced covalent cross-linking of MP and the non-covalent interaction of curdlan with myofibrillar proteins.Additionally,the freeze-thaw stability of the dual-network surimi gels was further investigated in terms of gel strength,WHC,rheological properties,and ice crystal morphology.The results suggested that the gel strength and WHC of the TG/C dual-network surimi gels(0.4%TGase and 1%curdlan)showed the smallest decreases of 24.38%and 9.29%after five freeze-thaw cycles,respectively,compared with control group.In addition,the TG/C dual-network surimi gels showed a small size and uniformly distribution of the ice crystals.Differential calorimetric analysis indicated that the TG/C dual-network surimi gels had the lowest freezable water content and gel eutectic point,which demonstrated that the microstructure ice suppression strategy based on the dual-network structure modulation could slow down the ice crystal growth-induced deterioration of the gel quality,and enhance the freeze-thawing stability of the gel.The results of this study can provide theoretical references for the development and design of high-quality surimi gels with stable freeze-thaw quality.关键词
