摘要
猪油与油溶性乳化剂、水溶性乳化剂及壁材等在一定条件下混合均匀、乳化、均质 ,经喷雾干燥得粉末化猪油。单因素试验表明 ,最佳乳化条件为 :壁材为大豆分离蛋白、β -环状糊精和可溶性淀粉复合使用 ,亲油乳化剂为单甘酯 ,亲水乳化剂为Tween 6 0 ,HLB值为 6~ 8,乳化剂用量2 %~ 3% ,稳定剂明胶用量 1.6 %~ 2 .0 % ,加水量 10~ 15倍于基料 ,乳化温度 70℃ ,乳化时间 2 0min。在其他条件不变的情况下 ,通过正交试验研究了乳化剂用量、HLB值、明胶用量和壁材对粉末化猪油的溶解度、产品结块状态的影响。研究结果表明 ,制备 4 0 %含油量的粉末化猪油的最佳配方为 :乳化剂用量 3% ,HLB值 6 ,明胶用量 2 .3% ,大豆分离蛋白、β -环状糊精和可溶性淀粉复合作壁材。
In a certain conditions,lard,wall material and emulsifying agent was mixed,emulsified,homogenized,and then dried with spray drier to obtain powdered lard.By single factors experiment,the optimum emulsification conditions were got as follows:wall material was the mixture of soybean protein isolate,β-cyclodextrin and soluble starch,emulsifying agent was Tween 60 and monoglyceride,HLB was 6~8,dosage of emulsifying agent was 2%~3%,dosage of glutin was 1.6%~2.0%,emulsifying temperature and time was 70℃ and 20 minutes,respectively.By orthogonal experiment,the formula of 40% powdered lard was researched by reviewing the product index of solubility and agglomeration,and its optimum formula was the dosage of emulsion agent 3%,HLB 6,dosage of glutin 2.3%,and the mixture of soybean protein isolate,β-cyclodextrin and soluble starch as wall material.
