摘　　要：为探究超微粉碎处理对多花黄精粉特性的影响,本文采用粉碎过筛处理制备不同粒径(50、100、200、325目)多花黄精粉末,并用扫描电子显微镜及傅里叶红外光谱对其物理特性开展研究,同时模拟体外胃肠消化过程。结果表明,经过粉碎及过筛处理后,多花黄精粉粒径大小具有显著性差异(P<0.05)。粉碎过程仅破坏了粉体的表面结构,并未破坏粉体的分子结构。多花黄精粉的休止角、溶解度随粒径的减小不断增加,而堆密度、润湿时间、持水力不断下降。此外,粉碎度为200目(75μm,超微粉Ⅰ)的粉体活性物质多糖含量为15.37%,显著高于其他样品(P<0.05)。体外模拟胃肠消化过程中,粉碎度为200目(75μm,超微粉Ⅰ)的粉体多糖释放量最高,且具有一定体外抗氧化能力。综上,多花黄精粉碎时粉体过200目筛时,多糖释放量最高。本实验为多花黄精粉末的产业化应用提供了理论依据。To investigate the functional effects of superfine grinding treatment on Polygonatum cyrtonema Hua powder,in this study,the sample was ground and sieved by pharmacopoeia test sieves(50,100,200 and 325 mesh)to prepare P.cyrtonema Hua powder with different particle sizes.Its physical properties were studied using scanning electron microscopy and Fourier transform infrared spectroscopy,while the in vitro gastrointestinal digestion process was simulated.The results showed that the particle size of P.cyrtonema Hua powder exhibited a significant difference(P<0.05)following grinding and sieving treatment.The grinding process only destroyed the surface structure of the powder,but did not destroy the molecular structure of the powder.The angle of repose and solubility of P.cyrtonema Hua powder exhibited a continuous increase with decreasing particle size,while bulk density,wettability and water holding capacity showed a decreasing trend.Additionally,the polysaccharide content of the sample with 200 mesh(15.37%)was significantly higher than that of other samples(P<0.05).Moreover,the polysaccharide release content of the powder with 200 mesh(75μm,ultrafine powderⅠ)during in vitro gastrointestinal digestion was higher than that of other powders.Ultrafine powderⅠalso had a certain antioxidant ability.In summary,when the powder of P.cyrtonema Hua is sieved by 200 mesh sieve,the content of polysaccharide released is the highest.This experiment provides a theoretical basis for the practical application of P.cyrtonema Hua powders.
