【摘要】 以黄豆粉、脱脂奶粉、木糖醇和树莓籽粉末油脂(RSOP)为主要原料制备RSOP豆奶粉。以感官评分为指标，通过单因素试验和响应面试验优化RSOP豆奶粉配方，并对其营养成分和抗氧化活性进行分析。结果表明：最优配方为以黄豆粉质量为基准，RSOP添加量20%、木糖醇添加量14%、脱脂奶粉添加量65%。在此条件下制得的RSOP豆奶粉均匀无结块，呈淡黄色，无豆腥和油脂气味，蛋白质含量为29.41%±2.04%,对DPPH自由基和羟基自由基具有较高的清除能力，表明RSOP豆奶粉具有较好的抗氧化活性。更多还原

【Abstract】 Raspberry seed oil powder(RSOP) soy milk powder was prepared using soybean powder, skim milk powder, xylitol and RSOP as the main raw materials. Taking sensory score as an indicator, the formula of RSOP soy milk powder was optimized by single factor tests and response surface test, and the nutritional components and antioxidant activity of RSOP soy milk powder were analyzed. The results showed that the optimal formula was based on the mass of soybean powder, RSOP addition 20 %, xylitol addition 14 %, and skim milk powder addition 65 %. Under the conditions, the RSOP soy milk powder was uniform and free of clumps, appearing light yellow in color with no odor of bean odor or oil. Its protein content was 29.41 %±2.04 %, and it had a high ability to scavenge DPPH and hydroxyl radicals, indicating that RSOP soy milk powder had good antioxidant activity.更多还原
