本研究考察了荞麦粥生产工艺对膳食纤维含量、膳食纤维组分的影响，以及荞麦粥及其制品对选定胆汁酸的吸附。对荞麦颗粒（BC）、焙烧后荞麦颗粒（BGR）、荞麦壳（BH）、荞麦麸皮（BB）、全荞麦粒（WBG）、碎荞麦粒（BBG）和荞麦废（BW）进行了样品分析。采用Van Soest法测定中性洗涤性膳食纤维（NDF）及其含纤维素(C)、半纤维素(H)和木质素(L)部分的含量，采用Asp法测定总膳食纤维（TDF）及其可溶性（SDF）和不可溶性（IDF）部分的含量。用比色法研究了其对胆酸（CA）、去氧胆酸（DCA）和去氢胆酸（DHA）的吸收能力。观察了受检产品中膳食纤维含量及其比例的差异。TDF含量最高的是BH，最低的是BBC。荞麦壳中L和C组分含量最高，而荞麦废料中L组分含量较高，其中IDF组分在所有产品中占主导地位。在所研究的胆汁酸中，DCA的吸附效果最强，CA的吸附效果最弱。胆酸与BH、BB和BW的结合显著高于其他产物。与WBG和BBC相比，荞麦壳的胆汁酸结合力显著提高。(C) 2011 Elsevier Ltd.版权所有。
This study examined the influence of the technological process of buckwheat groats production on dietary fibre content and its fraction, and sorption of selected bile acids by buckwheat groats and products. Analyses were conducted on samples of the following products: buckwheat grains (BC), buckwheat grains after roasting (BGR), buckwheat hull (BH), buckwheat bran (BB), whole buckwheat groats (WBG), broken buckwheat groats (BBG) and buckwheat waste (BW). The content of neutral detergent dietary fibre (NDF) and its fraction containing cellulose (C), hemicellulose (H) and lignin (L) were assayed using the Van Soest method, while total dietary fibre (TDF) and its soluble (SDF) and insoluble (IDF) fractions were assayed using the Asp method. Ability to absorb cholic acid (CA), deoxycholic acid (DCA) and dehydrocholic acid (DHA) was investigated by colorimetric methods. Differences in the content of dietary fibre and its fraction in examined products were observed. The highest TDF content appeared in BH, while the lowest in BBC. The buckwheat hull contained highest amount of fraction L and C, while the buckwheat waste contained more fraction L. The IDF fraction predominated in all products. Among investigated bile acids DCA was adsorbed the strongest, while CA the weakest. Cholic acid binding was significantly higher with BH, BB and BW than with rest products. For buckwheat hull bile acid binding was significantly higher in comparison with WBG and BBC. (C) 2011 Elsevier Ltd. All rights reserved.
