In the following study, dietary fiber, insoluble (IDF), soluble (SDF) and total (TDF) were determined in cereals and by-products and in commercial cereals products which are found in the national market and promoted as a source of fiber. The Prosky's enzimatic-gravimetric method was used. Results were expressed as g/100g wet basis. Total dietary fiber in cereals and by-products showed a range from 1.18% (poshed rice) to 89.10% (corn bran). For the commercial cereal products, the TDF values varied from 3.73% (rice-sesame cookies) to 34.96% (Breakfast cereal named All Bran). The FDI values always were greater than the SDF values. Based on this fact, FDI values were compared with NDF (Neutral Detergent Fiber) values reported in the scientific literature and in the Venezuelan Food Composition Tables using a regression analysis. FDI values were always greater than NDF values and the correlation factor (r) was high and statistical significance to P < 0.05 for both food groups in study.
在以下研究中，测定了谷物及其副产品以及在国内市场上作为纤维来源销售的市售谷物产品中的膳食纤维，包括不溶性膳食纤维（IDF）、可溶性膳食纤维（SDF）和总膳食纤维（TDF）。采用了普罗克斯酶重量法。结果以克/100克湿基表示。谷物及其副产品中的总膳食纤维含量范围为1.18%（精米）至89.10%（玉米麸）。对于市售谷物产品，TDF值在3.73%（米芝麻饼干）至34.96%（名为全麸麦的早餐谷物）之间变化。IDF值总是大于SDF值。基于这一事实，使用回归分析将IDF值与科学文献以及委内瑞拉食物成分表中报告的中性洗涤纤维（NDF）值进行了比较。IDF值总是大于NDF值，并且研究中的两个食物组的相关系数（r）都很高，且在P<0.05时具有统计学意义。
