竹荪营养代餐粉的研制及品质特性研究

Development and Quality Characteristics of Dictyophora indusiata Nutritional Meal Replacement Powder

摘要: 本文以竹荪粉、高纤膳食组合、麦芽糊精及赤藓糖醇为主要原料研制一款竹荪营养代餐粉。采用单因素实验及正交试验对竹荪营养代餐粉的配方进行优化，并对代餐粉营养成分、速溶特性等进行测定。研究表明，竹荪营养代餐粉的最佳配方为(以30 g/份为基准)：竹荪粉添加比例10%、高纤膳食组合添加比例45%、麦芽糊精添加比例20%、赤藓糖醇添加比例7%和果粉添加比例18%。在此配方下，代餐粉总糖含量为36.75 g/100 g，脂肪含量为11.36 g/100 g，蛋白质含量为18.20 g/100 g，分散性189 s，润湿性233 s，制得的竹荪营养代餐粉，口感清甜丝滑，风味协调，溶解性佳。

Abstract: This study was designed to develop a nutritional Dictyophora indusiata meal replacement powder taking Dictyophora indusiata powder, high-fiber dietary blend, maltodextrin, and erythritol as the primary raw materials. The formulation of the nutritional Dictyophora indusiata meal replacement powder was optimized through single-factor experiments and orthogonal tests, and its nutritional composition, antioxidant activity, and instant properties were determined. The research demonstrated that the optimal formulation of the nutritional Dictyophora indusiata meal replacement powder was as follows (based on a 30 g/serving benchmark): Dictyophora indusiata powder 10%, high-fiber dietary blend 45%, maltodextrin 20%, erythritol 7%, and fruit powder 18%. Under this formulation, the total sugar content of the meal replacement powder was 66.75 g/100 g, fat content 15.36 g/100 g, protein content 18.10 g/100 g, vitamin C content 1.82 mg/100 g, and moisture content 4.85 g/100 g. The DPPH free radical scavenging rate reached 83%. The prepared nutritional Dictyophora indusiata meal replacement powder was characterized by a mildly sweet and silky taste, well-balanced flavor, and excellent solubility.
