为探索流化冰对冰鲜水产品保鲜效果,以鲣鱼鱼肉为研究对象,以传统碎块冰保鲜为对照,探讨流化冰处理对鲣鱼肌肉蛋白质功能特性影响。结果表明:1)流化冰冰粒子呈球形,外表光滑、单位表面积大且流动性能好,8 min内可将鱼肉整体温度由35℃降低至1.3℃;2)-4℃贮藏18 d后,流化冰保鲜处理的鱼肉弹性和咀嚼性依次为1.19 mm和5.50 m J,而空白(不加冰)、淡水碎块冰组分别为0.67 mm和1.65 m J、0.95 mm和3.32 m J,可见流化冰对鱼肉质构特性保持效果显著(P<0.05);3)0~18 d贮藏期内,不同处理鲣鱼肌原纤维蛋白含量、Ca2+-ATPase活性及总巯基含量均呈逐渐下降趋势,其中以流化冰处理对鲣鱼蛋白质功能特性的保持效果最佳;此外,流化冰保鲜还兼具有抑制鱼肉氧合肌红蛋白自动氧化、维持肌肉原有色泽的作用。流化冰处理显著保持了鲣鱼肌肉组织的质构和相关蛋白质功能特性,可满足冰鲜水产品远洋、长距离运输和保鲜贮藏要求。

A statistical formalism overcoming some conceptual and practical difficulties arising in existing two-phase flow (2PHF) mathematical modelling has been applied to propose a model for dilute 2PHF turbulent Hows. Phase interaction terms with a clear physical meaning enter the equations and the formalism provides some guidelines for the avoidance of closure assumptions or the rational approximation of these terms. Continuous phase averaged continuity, momentum, turbulent kinetic energy and turbulence dissipation rate equations have been rigorously and systematically obtained in a single step. These equations display a structure similar to that for single-phase flows. It is also assumed that dispersed phase dynamics is well described by a probability density function (pdf) equation and Eulerian continuity, momentum and fluctuating kinetic energy equations for the dispersed phase are deduced. An extension of the standard k-e turbulence model for the continuous phase is used. A gradient transport model is adopted for the dispersed phase fluctuating fluxes of momentum and kinetic energy at the non-colliding, large inertia limit. This model is then used to predict the behaviour of three axisymmetric turbulent jets of air laden with solid particles varying in size and concentration. Qualitative and quantitative numerical predictions compare reasonably well with the three different sets of experimental results, studying the influence of particle size, loading ratio and flow confinement velocity.
