淀粉是葡萄糖分子聚合而成的长链化合物,它是细胞中碳水化合物最普遍的储藏形式,在细胞中以颗粒状态存在,称为淀粉粒(starch grain)。所有薄壁细胞中都有淀粉粒存在,尤其在各类贮藏器官中更为集中,如种子的胚乳和子叶中,植物的块根、块茎和根状茎中都含有丰富的淀粉粒。
Effects of starch granule size distribution on pasting property of reconstituted starch decreased when the fraction of B-type granules was higher than 30%.
重组淀粉中B-型淀粉粒的重量比例小于30%时对淀粉糊化特性影响很大,超过30%后,淀粉粒粒级分布对糊化特性的影响变小。
