摘要: 以黑米、牛奶为主要原料制作一种复合型黑米谷物牛奶,选择色泽、质地、滋味及香气4个因素作为感官评价指标,通过正交试验确定最佳感官配方为:牛奶50.0%、黑米粉5.5%、乳化剂0.2%、白砂糖4.0%。利用稳定分析仪的稳定动力学参数为评价指标,以保质期为6个月的灭菌乳为对照,在最佳感官配方基础上,研究复配稳定剂的使用对成品黑米谷物牛奶稳定性的影响。结果表明,由0.20%微晶纤维素、0.15%变性淀粉和0.02%的к-卡拉胶组成的复合稳定剂的稳定效果最好;由0.20%微晶纤维素和0.15%变性淀粉组成的复合稳定剂的稳定效果其次,以上2种复合稳定剂均能使黑米谷物牛奶的稳定效果达到6个月保存期的要求。

Abstract: A nutritional beverage was developed by combination of black kerneled rice and milk.Appearance,texture,taste and flavor were chosen as sensory index and the prescription was determined by orthogonal experiment.In addition,the stability also were analyzed by turbiscan technology using six months shelf-life UHT milk as control.The results showed that the prepared sample containing 50.0% milk,5.5% black kerneled rice powder,0.20% emulsifier,4.0%sugar had the best sensory character.For the stabilities of black kerneled rice milk,one compound-stabilizer including 0.20% Microcrystalline Cellulose(MCC),0.15% modified starch and 0.02% к-carrageenan was better than the another one composed of 0.2% MCC and 0.15% modified starch.Moreover,the stabilities of samples were both better than that of the control.Therefore,two above compound-stabilizers can satisfied the need of the stability of black kerneled rice milk in six months shelf-life.
