This paper characterizes starch and dietary fibre in the seeds of fine-size and large-size seed varieties of broad bean and in edible varieties of pea for comparison. The experimental material included seeds at full physiological maturity. The fine-size seed varieties of broad bean, Gobik and Goral, contained slightly less total starch (62.32% and 62.19% of dry matter) than the large-size seed varieties, Windsor Bialy and Bartom (65.32% and 65.26% of dry matter). It was shown that fine-size seed varieties of broad bean are a good source of resistant starch, which is comparable to large-size seed varieties. As far as the content of total starch is concerned, the share of this form of starch in broad bean seeds amounted to 1/3. Digestible starch in broad beans was in the range of 39-42% of dry matter, pea contained approximately one half less starch of this type. Moreover, it was found that the relation of rapidly digestible starch to slowly digestible starch amounted to 1:1 irrespective of broad bean variety. Dietary fibre in broad beans was in the range of 20.36%-26.79% of dry matter while half of it was found to be concentrated in the seed coat. The soluble fraction of the total content of fibre amounted to 11.81% in the Bartom variety and up to 15.89% in the Gobik variety.
本文对蚕豆的小粒和大粒种子品种以及豌豆食用品种种子中的淀粉和膳食纤维进行了表征比较。实验材料包括生理成熟的种子。蚕豆的小粒种子品种戈比克（Gobik）和戈拉尔（Goral）的总淀粉含量（分别占干物质的62.32%和62.19%）略低于大粒种子品种温莎比亚利（Windsor Bialy）和巴托姆（Bartom）（分别占干物质的65.32%和65.26%）。结果表明，蚕豆的小粒种子品种是抗性淀粉的良好来源，与大粒种子品种相当。就总淀粉含量而言，这种淀粉形式在蚕豆种子中的占比达三分之一。蚕豆中可消化淀粉占干物质的39 - 42%，豌豆中这类淀粉的含量约少一半。此外，研究发现，无论蚕豆品种如何，快速消化淀粉与缓慢消化淀粉的比例均为1:1。蚕豆中膳食纤维占干物质的20.36% - 26.79%，其中一半集中在种皮中。纤维总含量的可溶部分在巴托姆品种中占11.81%，在戈比克品种中高达15.89%。
