Abstract
The objectives of this article were to determine the content of total dietary fi bre (TDF) as well as of its fractions – soluble dietary fi bre (SDF)
and insoluble dietary fi bre (IDF) of different cereals grown by conventional and organic farming in Macedonia, as well as to fi nd out the infl uence
of the cereal type and farming method on their values. Standardized enzymatic-gravimetric method (Megazyme Total Dietary Fiber Kit) was used for
determination of soluble, insoluble, and total dietary fi ber in 27 different cereal samples of wheat, rye, barley, oat, and millet, which were grown at
three locations. The content of TDF, IDF and SDF was infl uenced by both cereal type and farming type. The organically grown cereals, primarily oat
and barley, have shown higher values of TDF and of its fractions than the conventionally grown cereals. Their values (% db) for oat and barley for TDF
were 42.00±1.39 and 21.91±2.01, for IDF 39.22±0.58 and 15.06±1.84 and for SDF 2.78±1.25 and 6.85±3.85, respectively. Barley grown by either
organic or in conversion farming method proved to have the highest value of SDF content among the other cereals investigated, whereas oat produced
by organic farming method exhibited the highest values of TDF and ISF content. The organic farming method proved to have a good perspective
in cereal processing and technology, food market and nutrition
