摘　　要：为高效利用牛脂,以液态延边黄牛脂熔点及得率为指标,以表面活性剂添加量、电解质添加量、养晶温度和养晶时间为试验因素,设计4因素3水平正交试验优化延边黄牛脂原油分提工艺,利用复凝聚法将其制备成微胶囊,应用于牛肉粉产品,并进行了对比。结果得出:最佳分提条件为表面活性剂添加量2.53%、电解质浓度4%、养晶温度41.33℃、养晶时间4.76 h,在此条件下得到液态延边黄牛脂(简称液油)、固态延边黄牛脂(简称固脂)。分提得到的液油熔点为(37.15±0.17)℃,得率为(73.20±0.51)%,且利用液油微胶囊制备的牛肉粉品质更优。In order to efficiently utilize tallow,a 4-factor 3-level orthogonal experiment was designed to optimize the extraction process of Yanbian yellow cattle tallow crude oil using the melting point and yield of liquid Yanbian yellow cattle tallow as indicators,and the amount of surfactant added,electrolyte added,crystallization temperature,and crystallization time as experimental factors.The complex coagulation method was used to prepare microcapsules,which were applied to beef powder products and compared.The results showed that the optimal extraction conditions were surfactant concentration of 2.53%,electrolyte concentration of 4%,crystal growth temperature of 41.33℃,and crystal growth time of 4.76 hours.Under these conditions,liquid Yanbian yellow cattle tallow(referred to as liquid oil)and solid Yanbian yellow cattle tallow(referred to as solid tallow)were obtained.The melting point of the extracted liquid oil was(37.15±0.17)℃,and the yield was(73.20±0.51)%.Moreover,the beef powder prepared using liquid oil microcapsules had better quality.
