高膳食纤维谷物代餐粉的制备及其品质特性

Preparation and Quality Characteristics of High Dietary Fiber Cereal Meal Replacement Powder

为制备一款兼具调节肠胃和减肥功能的高膳食纤维代餐粉,该研究以燕麦粉、藜麦粉、荞麦粉、魔芋粉为谷物原料通过等级一致性检验确定基础谷物粉的最优配比,以党参∶山楂∶陈皮=1∶1∶1(质量比)的混合粉为主要原料,结合大豆分离蛋白、脱脂乳粉、木糖醇、三氯蔗糖、苹果粉,以感官评分为指标通过单因素试验和响应面试验确定代餐粉中各原辅料的最适添加量。结果显示代餐粉的最优配方为燕麦粉8.86 g、藜麦粉13.29 g、荞麦粉4.43 g、魔芋粉4.43 g、大豆分离蛋白10 g、脱脂乳粉8 g、混合粉2 g、木糖醇4.87 g、三氯蔗糖0.0192 g、苹果粉3.92 g。此配方下的代餐粉色泽明亮、谷香浓郁、口感醇和,粗蛋白、粗脂肪、膳食纤维的含量分别为24.36、2.30、38.06 g/100 g。粉质特性测定结果显示,该代餐粉溶解度和水合能力较好,流动性一般,不易飞溅。冲调后质构测定显示该代餐粉有一定表面硬度,稠度适中、黏度低,所制得的代餐粉富含高膳食纤维,具有调节肠胃功能。

To prepare a high dietary fiber meal replacement powder with both gastrointestinal function regula⁃tion and weight reduction effects,this study used oat powder,quinoa powder,buckwheat powder,and konjac powder as grain raw materials to determine the optimal ratio of basic grain powder through grade consistency testing.The main raw materials for regulating gastrointestinal function were mixed powder(Codonopsis pilosula∶hawthorn∶tangerine peel=1∶1∶1,mass ratio),which was derived from medicinal and food sources,combined with soy protein isolate,defatted milk powder,xylitol,sucralose,and apple powder.Sensory evaluation was used as an indicator to determine the optimal amount of raw materials and excipients in meal substitutes through single⁃factor experiments and response surface methodology experiments.The results showed that the optimal formula for meal replacement powder was 8.86 g of oat powder,13.29 g of quinoa powder,4.43 g of buckwheat powder,4.43 g of konjac powder,10 g of soy protein isolate,8 g of skimmed milk powder,2 g of mixed powder,4.87 g of xylitol,0.0192 g of sucralose,and 3.92 g of apple powder.The meal replacement pow⁃der under this formula exhibited a bright color,rich grain aroma,and a mellow taste.The protein,fat,and di⁃etary fiber content were 24.36,2.30 g/100 g,and 38.06 g/100 g,respectively.The measurement results of pow⁃der properties showed that the solubility and hydration ability of this generation of meal powder were good,the fluidity was average,and it was not easy to splash.The texture measurement after blending showed that the meal powder had a certain surface hardness,moderate consistency,and low viscosity.The meal replacement powder produced was rich in high dietary fiber and can regulate gastrointestinal function.
