摘要
以犊牛肉为研究对象,失水率、持水力为评鉴指标,采用U12(124)均匀实验设计优化无磷保水剂复合配比,结合衬垫托盘包装,对冷鲜犊牛肉保水性及嫩度进行研究,结果表明:无磷保水剂最佳配比为:乳酸钠0.2%、醋酸钠1%、氯化钠0.25%、壳聚糖0.8%。该保水剂对冷鲜犊牛肉具有明显的保水嫩化作用,使冷鲜犊牛肉失水率降低41.4%,持水力提高8.79%,剪切力降低至2.90 kg(P<0.05)。
In combination with liner pallet packaging, the ability of water retention and tenderness of calf beefwere studied by U12（124） uniform experimental design to optimize the composite ratios of non-phosphorus water retention agents with water loss and water holding capacity as evaluation indicators. The results showed that the optimum ratios of non-phosphorus water retention agents were sodium lactate was 0.2%, sodium acetate was 1%, sodium chloride was 0.25% and chitosan was 0.8%. The water-retention had obvious water retention and tenderization effects on cold fresh veal with the rate of water loss reduced 41.4%, the ability of water retention increased 8.79% and shear force reduced to 2.90 kg respectively.
