高γ-氨基丁酸发芽营养粉的研制

Development of germinated nutritional grain powder with high γ- Aminobutyric acid

以富含γ-氨基丁酸(GABA)的发芽糙米粉、发芽大豆粉和发芽玉米粉为主要原料,研制高GABA发芽营养粉,以其色泽、冲调性、适口性和稳定性为考察指标,通过混料设计和正交实验优化发芽营养粉配方。结果表明,发芽营养粉的最优配方为发芽糙米粉40.0%、发芽大豆粉21.9%和发芽玉米粉38.1%,在此条件下营养粉的综合评分最高,达72.23;添加蔗糖8%,麦芽糊精11%,植脂末14%和脱脂奶粉7%时,发芽营养粉风味最好,产品中GABA含量高达16.63mg/100g。

The formula of germinated nutritional grain powder including germinated brown rice, germinated soybean and germinated corn was optimized by D- optimal mixture regression design and orthogonal design and parameters of chromaticity, palatability, brewing and stability were evaluated.The optimal formula of nutritional powder was obtained ：the ratio of germinated brown rice flour, germinated soybean flour and germinated corn flour was 40.0% ,2L9% ,38.1 % ,respectively.The sensory evaluation score reached 72.23 for this ratio.Optimum flavor of the nutritional powder was obtained at a ratio of sugar,maltodextrin,creamer and skimmed milk of 8%, 1 1%, 14% and 7%, respectively.GABA content reached 16.63 mg/100g for this formula.
