A new calculation method was suggested for the determination of insoluble and soluble food fibres. The method was based on the data of chemical analysis of cellulose, lignin, pectin, and hemicelluloses with the usage of experimentally determined correlation coefficient. Insoluble food fibres are calculated according to the sum content of cellulose, lignin, and 2/3 of hemicelluloses multiplied by the corresponding correlation coefficient. Soluble food fibres are calculated according to the sum content of pectin and 1/3 of hemicelluloses multiplied by correlation coefficient. Correlation coefficient depends upon the type of the product.
提出了一种测定不溶性和可溶性膳食纤维的新计算方法。该方法基于纤维素、木质素、果胶和半纤维素的化学分析数据，并使用实验测定的相关系数。不溶性膳食纤维根据纤维素、木质素和2/3半纤维素的总含量乘以相应的相关系数来计算。可溶性膳食纤维根据果胶和1/3半纤维素的总含量乘以相关系数来计算。相关系数取决于产品类型。
