运用广角X-射线衍射分析方法对橡实淀粉的结晶结构进行了系统研究,结果表明:橡实淀粉粒是一种由非晶相、亚微晶相和微晶相三种结构所组成的多晶体系,其结晶度分别为锥栗淀粉34.88%、茅栗淀粉35.12%、小红拷淀粉35.23%、栓皮栎淀粉35.31%、硬斗石栋淀粉33.53%、星毛石砾淀粉34.69%、美叶石栋淀粉35.06%、长叶石烁淀粉31.58%、云山青冈淀粉33.83%、大叶青冈淀粉32.11%.

In this paper the crystalline structure of acorn starch granules were studied by means of X-ray diffraction examination.The results indicated that acorn starch granule was a kind of multl-crystal system made from crystal, sub-crystal andnon-crystal,and that the crystallinities were 34.88% of castanea henryi starch, 35.12% of castanea seguinii starch, 35.23%of castanopsiscarlesii starch, 35.31% of quercus variabilis starch, 33.53% of lithocarpus hancei starch, 34.69% of lithocarpus petetii starch,35.06% of lithocarpus calophylla starch, 31.58% of lithocarpus henryi starch, 33.83% of cyclobalano...
