The objective of this study was to investigate the effects of partial beef fat replacement (0, 30, 50, 100%) with gelled emulsion (GE) prepared with olive oil on functional and quality properties of model system meat emulsion (MSME). GE consisted of inulin and gelatin as gelling agent and characteristics of gelled and model system meat emulsions were investigated. GE showed good initial stability against centrifugation forces and thermal stability at different temperatures. GE addition decreased the pH with respect to increase in GE concentration. Addition of GE increased lightness and yellowness but reduced redness compared to control samples. The results of the study showed that partial replacement of beef fat with GE could be used for improving cooking yield without negative effects on water holding capacity and emulsion stability compared to C samples when replacement level is up to 50%. The presence of GE significantly affected textural behaviors of samples (<0.05). In conclusion, our study showed that GE have promising impacts on developing healthier meat product formulations besides improving technological characteristics.
本研究的目的是探讨用橄榄油制备的凝胶乳液(GE)部分替代牛肉脂肪(0%、30%、50%、100%)对模型体系肉糜(MSME)功能和品质特性的影响。GE由菊粉和明胶作为凝胶剂组成,并对凝胶肉糜和模型体系肉糜的特性进行了研究。GE在离心力作用下具有良好的初始稳定性,在不同温度下具有热稳定性。随着GE浓度的增加,GE的添加降低了pH值。与对照样品相比,添加GE增加了亮度和黄度,但降低了红度。研究结果表明,与C样品相比,当替代水平高达50%时,用GE部分替代牛肉脂肪可用于提高烹饪产量,而对持水能力和乳液稳定性没有负面影响。GE的存在显著影响样品的质地行为(<0.05)。总之,我们的研究表明,GE除了改善技术特性外,对开发更健康的肉制品配方具有潜在影响
