响应面法优化花香型阿胶羊乳膏的制备工艺

Response Surface Methodology for Optimization of the Formulation of Donkey Hide Glue Containing Aqueous Extract from Edible Flowers and Skim Goat Milk

在单因素试验的基础上,利用Box-Behnken响应面优化确定花香型阿胶羊乳膏的加工工艺及配方,并测定及分析其主要理化指标,明确产品的保健功效。结果表明:最佳工艺参数下的配方(均为质量分数)为:脱脂羊乳62.4%、阿胶6.2%、花汁14.9%及复合胶凝剂0.075%,在此条件下所制得的产品感官评分可达9.6分,凝胶强度为35.8 g。理化指标分析结果表明:产品中蛋白质含量≥6.80 g/100 g产品,脂肪含量≤4.00 g/100 g产品,该产品为高蛋白、低脂产品,具有补血养颜之功效。

The formulation of donkey hide glue containing aqueous from edible flowers and skim goat milk was optimized using combination of one-factor-at-a-time method and response surface methodology with Box-Behnken design. The response variables were sensory evaluation scores and gel strength. The results showed that the optimum formulation was composed of 62.4% skim goat milk, 6.2% donkey hide glue, aqueous flower extract 14.9%, and 0.075% composite gelling agent. The resultant product showed a sensory score of 9.6 and a gel strength of 35.8 g. Physicochemical analysis indicated that the product contained ≥ 6.80 g of protein and ≤4.00 g of fat per 100 g of sample and thus could nourish blood and maintain beauty as a high-protein, low-fat product.
