Content of TDF, SDF and IDF in Cereals Grown by Organic and Conventional Farming – a Short Report

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.

Characterization and Prebiotic Potential of Longan Juice Obtained by Enzymatic Conversion of Constituent Sucrose into Fructo-Oligosaccharides

“…The content of insoluble fiber was determined using the method of [ 37 ]. Briefly, 1 g of the dried residue sample ( Section 2.2 ) was subjected to sequential enzymatic digestion by thermal-stable α-amylase, protease and amyloglucosidase.…”

Nutritional and functional properties of cookies made using down‐graded lentil – A candidate for novel food production and crop utilization

“…Thus, NDF was used as a rapid screen closely related to dietary fibre but does not measure the content of other constituents such as pectin (Van Soest & Robertson, 1981). Therefore, product development arising from this research would require a more mainstream analyses to measure total dietary fibre, such as the AACC total dietary fibre (TDF) method, 32-05.01 (McCleary, 2010;Menkovska et al, 2017) or with the Megazyme K-TDFR total dietary fibre assay (Hollmann, Themeier, Neese, & Lindhauer, 2013).…”

Biochemical Aspects of Diabetes Mellitus

“…Due to its shorter duration of action, Levemir requires (in 45% of patients) two administrations per day to approach the physiological secretion of basal insulin. Prandial insulin is titrated according to the preprandial, postprandial glycemias and the amount of carbohydrates in each meal [38][39][40].…”
