    Abstract:
    The influence of different addition forms of κ-carrageenan, including powder, pre-suspended in water, and pre-suspended in brine, on the textural and gel properties of frankfurters were investigated. Compared with the control group, each addition form of κ-carrageenan led to a lower cooking loss, as well as higher emulsion stability with more trapped water within frankfurters (P < 0.05). Moreover, κ-carrageenan powder or κ-carrageenan water suspension addition could render higher hardness, adhesiveness, springiness, chewiness, fracturability, and resilience of frankfurters than control group (P < 0.05), which was verified by dynamic rheology analysis. However, κ-carrageenan brine suspension addition had negative effects on the above characteristics. Microstructural images indicated that κ-carrageenan could help form finer and denser protein matrices. However, the interaction modes between the meat protein matrix and each addition form of κ-carrageenan were distinct. Additionally, the addition of κ-carrageenan water suspension had the best effect on the improvement of the textural and gel properties of frankfurters with an enhanced overall acceptability.
