| 摘 要： | 将经过超临界CO2萃取脱脂的玉米胚芽应用于乳饮料的生产,以乳饮料的稳定性及感官品质评定作为考察指标,通过单因素试验与正交试验相结合的方法确定玉米胚蛋白乳饮料最佳工艺,并研究其稳定性.结果表明:脱脂玉米胚蛋白乳饮料的最佳工艺条件为:各成分以质量分数计,脱脂玉米胚芽添加量3％、柠檬酸添加量0.2％、复合稳定剂添加量0.25％、乳粉添加量2.5％、绵白糖添加量10％.在此条件下,可得到组织状态均匀、风味独特、口感柔和细腻、酸甜可口且具有较好稳定性的脱脂玉米胚蛋白乳饮料.

| Abstract: | In this study, corn germ meal was defatted by supercritical CO2 fluid extraction and applied for the production
of a composite dairy beverage. The optimization of dairy beverage formulations for improved stability and sensory quality
was carried out using combination of single factor and orthogonal array experiments. The results showed that the optimal
formulation consisted of 3% of defatted corn germ, 0.2% of citric acid, 0.25% of compound stabilizer, 2.5% of milk powder,
and 10% of soft white sugar. The obtained beverage was characterized by homogenous texture, unique flavor, soft and
delicate taste, a good balance of sweet and sour, and good stability. |
