Optimization of Extraction Process and Product Preparation of Yanbian Yellow Cattle Tallow
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.
