[Calculation method in determination of dietary fiber in food products]

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.
