Despite the great variability in the content of carotenoids, vitamins and total folate, most of the analysed traditional foods from BSAC can be considered good sources of these compounds. Therefore, owing to their putative health benefits, the consumption of those with higher contents of these compounds should be encouraged and promoted.

Today, food is intended not only to satisfy hunger and provide necessary nutrients for human organism, but also to prevent nutrition-associated diseases and improve the mental and physical condition. The formula of food in the XXI century includes constant use of both traditional natural foods and foods with desired properties in the diet. The foods with desired properties are the functional food products, i. e. those enriched with essential food substances and micronutrients. These functional products cover a wide range of foods and ingredients with various biologically active substances responsible for their health-supporting and preventive effectiveness. This allows to lower the healthcare expenditures and support the economical development. The health and general well-being of today’s Ukrainians is influenced by many factors: rush life tempo, age-related changes in organs and tissues, heredity, unhealthy habits, stress situations etc. But the great importance of the diet and numbers and quality of products from which meals are prepared also should be kept in mind. And while we cannot change some factors, we can absolutely control others, particularly the characteristics of foods. The article presents some features of modern diet of Ukrainian population as an integral factor of health risk. Also, we show food substance consumption profiles of Ukrainian population in years 2015-2018, and the rate of functional foods on Ukrainian market in the last two years. The article is a review and highlights the necessity to develop production of functional foods based on fundamental and applied researches in food technology, nutritiology and the latest molecular biological technologies. General approaches to modern principles of functional food production technology are proposed. The role of the latest molecular biological technologies in functional food production is disclosed, especially of the proteomics, nutrigenomics and metabolomics. Important directions of functional food research are shown, they are associated with identification of new functional ingredients and increasing confidence of the consumers in such products. Motivations are proposed to stimulate the food manufactures to continue to develop the functional foods and to increase their assortment, thus providing a remarkable profit from successful products.

Abstract. The current study is a review of characteristics, production, physiological properties and application of xylooligosaccharides (XOS). XOS are the carbohydrates, their molecules are built from xylose residues linked mainly by в-(1→ 4)-glycoside bonds. Xylan is important for plant cell walls and is widely spread component in agricultural by-products. XOS are products of xylan hydrolytic degradation, and exhibiting the high prebiotic potential. The XOS preparation of wheat and rye bran stimulated the cells accumulation -1,4•10 10 CFU/cm 3 of L. аcidophilus and 9,2•10 10 CFU/cm 3 of В. bifidum. A difference in XOS molecules branching causes a wide range of their physiological properties: antioxidant, immunomodulation, antimicrobial, anti-inflammatory, anticarcinogenic. XOS can reduce high cholesterol level and triglycerides in blood plasma. XOS application reviewed in this article opens new perspectives on its potential use for human consumption. The rich sources of xylan are wheat, rye and barley bran, rice husk, wheat straw, corncobs, cotton stalk. Industrial way of XOS production includes chemical or enzymatic hydrolysis with following purification. Chemical methods are based on hydrothermal pretreatment and acidic or alkali extraction. Obtained oligosaccharides have a wide range of polymerization degree (DP) from 2 to 20. Enzymatic methods include fermentation with xylanase that allow controlling the XOS accumulation with certain DP. The different chromatographic purification after hydrolysis is used for analytical purposes. There are anion-exchange, size-exclusion, affinity, size-exclusion high-performance liquid chromatography. In addition, biomethods are preferred for XOS used in food, because such preparations do not contain monosaccharides and furfural as contaminants. XOS are stable in a wide range of temperature and pH, justifying the development of new synbiotics generation. Most widely XOS are used in production of functional products and pharmaceutical preparations. But they are also applied in cosmetic, agricultural and mixed feed industries.Keywords Анотація.

Streams of wheat milled fractions including peripheral parts of grain increase the content of bioactive substances and dietary fibre in blends with wheat graded flour.

The development of new physiologically functional food products is a prospective direction for world food products market. The inclusion of functional ingredients in food can increase the biological value of products that are already familiar to the consumer, as well as expand the range of products offered. Physiological activity of cereal’s ingredients varies widely, there are: anticancer, antiallergic, antioxidant properties, prebiotic, immunostimulating effects, etc. Moreover, the cereal’s ingredients can improve the organoleptic properties of bakery, dairy and confectionery. Cereals can be used as a prebiotics: fermentable substrates for the growth of probiotic microbiota. It is scientifically proven that grain’s nondigestible carbohydrates stimulate the growth of Lactobacillus acidophilus, L. casei, L. reuteri, L. rhamnosus, L. johnsonii, L. plantarum, Bifidobacterium longum, B. breve, B. lactis. Cereals contain water-soluble fibre, such as β-glucan and arabinoxylan, oilgosaccharides, such as xylo- and fructooligosaccharides and resistant starch, which have a wide application as prebiotic preparations. Furthermore, cereals as wheat, rye and rice contain polyphenols (benzoic and cinnamic acid derivatives) that are used both in the food industry as antioxidants, dyes, flavors of natural origin and in the compositions of physiologically functional ingredients, as well as in the pharmaceutical and cosmetic industries. Thus using cereals as a raw material for functional ingredients obtaining is a perspective in biotechnology, food and pharmaceutical industry. The modification of cereals processing technologies also will allow produce insufficiently studied prebiotic compounds, the functionality of which must be studied.
