双蛋白营养代餐粉的配制及其品质特性分析

以双蛋白营养粉为基料，以高纤膳食组合（魔芋粉、奇亚籽、菊粉）、麦芽糊精以及果粉为原料，研制一款高蛋白、高纤维、易饱腹、脂肪含量低、营养丰富的双蛋白营养代餐粉。对高纤膳食组合的粉碎方式及混料配方进行探究，发现三种原料按比例混合球磨产物得率高、颜色较浅、颗粒均匀；通过单因素实验和正交试验对代餐粉配方进行优化设计，得到最佳配方为:双蛋白营养粉添加量74%，高纤膳食组合添加量12.3%，麦芽糊精添加量8.5%和果粉添加量5.2%，此组合的代餐粉香气浓郁、入口顺滑、细腻，能够快速溶解。对该组合代餐粉的营养成分和粉体特性进行分析，结果表明，所制代餐粉蛋白含量明显高于市售同类产品（每100 g双蛋白营养代餐粉蛋白含量高达39 g），营养丰富，流动性好，无强烈飞溅性倾向，符合国际和国内相关标准。本研究为我国代餐粉行业发展提供了新的方向。

Preparation and Quality Characteristics of Dual-protein Nutrition Meal Replacement Powder

Using dual-protein nutritional powder as basic material, high fiber dietary combination (konjac powder, Chia seed, inulin), maltodextrin and fruit powder as raw materials, a dual-protein nutritional meal substitute powder with high protein, high fiber, easy satiety, low fat content and rich nutrition was developed. The crushing methods and mixing formula of high fiber dietary combination were studied, and it was found that the ball milling products of three kinds of raw materials had high yield, light color and uniform particles. The formula of meal substitute powder was optimized by single factor and orthogonal experiments, and the best formula was obtained as follows: 74% of dual-protein nutrition powder, 12.3% of high fiber diet, 8.5% of maltodextrin and 5.2% of fruit powder. The meal substitute powder of this formula could be dissolved quickly, and was fine and smooth, as well as with rich aroma. The nutritional composition and powder characteristics of meal substitute powder were analyzed. The results showed that the protein content was significantly higher than that of similar products on the market (the protein content of 100 g dual-protein meal replacement powder was 39 g). The meal replacement powder was rich in nutrition, with good fluidity and no strong tendency to splash, and met the Chinese and International Standards requirements. This study would provide a new direction for the development of meal replacement powder industry in our country.
