摘要: 以青稞β-葡聚糖为主要基质,研究一种降脂保健果冻的配方及制法。通过考察不同配方的组织形态、硬度和咀嚼感等9项感官指标初步筛选出果冻基质配方,以凝胶强度、黏度和持水性为指标用正交试验优化基质配方;以色泽、风味和口感为指标采用正交试验筛选添加有山楂和甘草提取物的青稞β-葡聚糖保健果冻的配方。结果表明:所得基质的配方(m/m)为5.0%青稞β-葡聚糖、0.5%明胶、5.0%甘油;保健果冻中添加剂用量(m/m)为山楂提取物1.5%、甘草提取物0.5%~2.5%、白砂糖8.0%。所制得的降脂保健果冻具有口感佳、安全防噎、入口即化的特点。

Abstract: The product formulation and preparation process for a jelly with lipid-lowering function using Tibetan hulless barley β-glucan (THBG) as main matrix material were investigated in this study. THBG, gelatin and glycerin was found to be the optimal jelly matrix components among 12 formulations in terms of sensory and texture properties, and the optimal jelly matrix composition was 5% THBG, 0.5% gelatin and 5% glycerin in terms of gel strength, viscosity and water-holding capacity as determined using orthogonal array design. Additives such as hawthorn extract, licorice extract and sugar were added to the matrix at concentrations of 1.5%, 0.5%-2.5% and 8.0%, respectively. The jelly obtained was a safe functional product with characteristics of good taste, no choking hazard and good meltability in the mouth.

Key words: Tibetan hulless barley, β-glucan, functional jelly, orthogonal array design
