快速分散型大豆分离蛋白代餐粉配方研究

A Formula of Fast Dispersing Meal Replacement Powder Based on Soy Protein Isolate

目的:以大豆分离蛋白为主要原料,开发冲泡后可以快速分散,稠度适中,口感顺滑的代餐粉配方。方法:以粒度分布和休止角评价大豆分离蛋白的流动性;以水溶分散时间和结块率为指标测定大豆分离蛋白快速分散性能;以口感测试结果确定大豆分离蛋白用量;以稠度和口感指标筛选了胶体种类配比以及用量;并以顺滑度和香气筛选了油脂种类和用量。结果:供应商B的大豆分离蛋白快速分散性佳,推荐用量为10g;黄原胶与瓜尔豆胶复配为最佳胶体方案,用量推荐为1.5g;油脂的优选方案为50%Fabuless复配50%MCT,用量推荐为3g。结论:开发的快速分散型大豆分离蛋白代餐粉配方水溶分散性良好,稠度适中,口感顺滑,香气浓郁。

【Objective】To develop the formula of meal replacement powder with soy protein isolate as the main raw material,which can disperse rapidly after water brewing,with moderate consistency and smooth taste.【Method】Particle size distribution and resting angle were tested for evaluating the fluidity of soybean protein isolate.The dispersion time and caking rate of soy protein isolate after water brewing were determined for evaluating the dispersivity of formula.Taste roughness and dosage of soybean protein isolate were screened by taste test testing.Colloid type ratio and dosage were selected by consistency and taste testing.The types and dosage of lipids were screened by smoothness and aroma testing.【Result】The soybean protein isolate from supplier B presented a good rapid dispersion and the recommended dosage was 10g.Xanthan gum and guar gum combination was the best colloid solution,and the dosage was recommended to be 1.5g.The optimal solution for lipids was 50%Fabuless combined with 50%MCT,and the recommended dosage was 3g.【Conclusion】The core formula of fast dispersing soybean protein isolate meal substitute powder represented a good dispersibility,moderate consistency,smooth taste and rich aroma.
