METHODS OF QUANTITATIVE AND QUALITATIVE DETERMINATION OF ARABINOXYLANS IN CEREALS (REVIEW)
Arabinoxylans (AXs) – non-starch polysaccharides (NSPs) is one of the most discussed main components contained in all parts of cereal plants. AXs combine bioactive and technological functions. As dietary fibres, they have physiologically beneficial properties for human health. AXs are water-soluble and insoluble in water. The structure, structure, quantity and properties of AXs depend on which part of the grain or cereal plant is extracted and which method of isolation is used. There are many different methods of preliminary and deep impact aimed at extraction of AXs from plant raw materials. The use of a simple method or complex treatment for quantitative and qualitative determination of AXs depends on objectives and possibilities. The overview provides data on AXs content of different crops, depending on the extraction method. The main classical methods of AXs extraction, their advantages, disadvantages, and possible limitations of use are described. The variants of calculation of the quantitative AXs content used by different authors are separately considered.
