摘要:

研究超微粉碎对香菇柄中多糖溶出率、膳食纤维含量和物理特性的影响。结果表明:经超微粉碎之后,香菇柄粉平均粒径降至8.05μm,多糖溶出率提升了1 倍多,总膳食纤维含量由43.23% 提高到48.91%,可溶性膳食纤维含量由5.66% 提高到15.64%,持水力、持油力和膨胀力分别提高了37%、46% 和109%。超微粉碎技术大幅提升了香菇柄中活性多糖的利用率,显著改善了其膳食纤维的功能特性,是香菇柄深度开发利用的一条可行途径。

Abstract:

The effect of superfine grinding on dissolution rate of polysaccharides, content of dietary fibers and physical properties of Lentinus edodes stems was investigated. Results indicated that Lentinus edodes stems exhibited a doubled increase in dissolution rate of polysaccharides, an increase from 43.23% to 48.91% in total dietary fiber, an increase from 5.66% to 15.64% in soluble dietary fiber, and an enhancement of 37%, 46% and 109% in water-holding capacity, oil-holding capacity and swelling capacity, respectively, when ground to the powder of 8.05 μm in particle size. Therefore, superfine grinding technology will be a feasible approach to the in-depth exploitation of Lentinus edodes stems due to its promotion on utilization rate of polysaccharides and significant improvement on functional properties of dietary fibers.

Key words: superfine grinding, Lentinus edodes stem, polysaccharide, dietary fiber
