The first method of this standard specifies the conditions and detailed analysis steps for the determination of total, soluble and insoluble dietary fiber in food by the enzymatic-gravimetric method. The first method of this standard is suitable for the determination of total, soluble and insoluble dietary fiber in cereals, vegetables and fruits and their products, but not for resistant maltodextrin, fructooligosaccharides, galactooligosaccharides, Determination of dietary fiber in foods such as polydextrose and resistant starch. The second method of this standard specifies the conditions and detailed analysis steps for the determination of total dietary fiber containing low molecular weight resistant maltodextrin in foods by enzymatic gravimetric method-liquid chromatography. The second method of this standard is applicable to the determination of total dietary fiber in foods such as candies and preserves (including chocolate and its products), grains and products, cakes, beverages, dairy products, meat products and health foods containing resistant maltodextrin.
