Introduction. For patients with gluten intolerance, diet therapy is the main method of treatment. However, gluten-free diets are found lacking in many important components. Children that fail to consume neccessary nutrients or have problems with their absorption tend to be physically retarded. Gluten-free diet may increase the risk of autoimmune diseases, especially type I diabetes. Therefore, products for children with celiac diseases should be both gluten-free and have adequate bioavailability of carbohydrates. This article features the chemical composition of amaranth, the geometric structure of starch grains, and its effect on the formation of colloidal solutions. It also compares the glycemic index (GI) of amaranth with other gluten-free grains, i.e. rice, buckwheat, and corn. Study objects and methods. The research featured native amaranth grain (Amaranthus cruentus) (Mexico), puffed amaranth kernels (Mexico), and coarse granular amaranth flour (Mexico). Results and discussion. Amaranth grain contains 12.5–23% of protein, 50.7–77.0% of carbohydrates, 6.0–8.0% of lipids, 10.5–18.3% of dietary fiber, and 2.5–3.5% of minerals. The GI of amaranth and its products were compared with similar values of other glutenfree crops, namely rice, buckwheat, and corn. Amaranth grain and its products demonstrated a higher GI, if compared with other gluten-free grain raw materials. The GI of amaranth grain was 87, the GI of the puffed amaranth kernels was 101, and the GI of the coarse granular amaranth flour was 97. Amaranth starch is easy to digest, which is mainly due to the high content of amylopectin (88 to 98%), since amylopectin breaks down faster than amylose. The relatively small size of starch granules (1.5–3.0 microns) increases the attack capacity of enzymes. These properties make amaranth starch glycemic, or low-resistant, which means that amaranth is easily digested and possesses stability to retrogradation. Conclusion. The unique nutritional and functional properties of amaranth gluten-free products can significantly improve the diet of children with gluten intolerance. However, amaranth starch and its products have a high GI. Hence, it is necessary to control the percentage of these components in formulations and be careful with the selection of additional components and their impact on the total GI.

Introduction. Diet therapy is one of the main approaches to the treatment of various diseases of the digestive system. A strict lifetime diet is the main method of treatment for gluten intolerance. However, young patients, who are particularly sensitive to dietary restrictions, often fail to follow the diet due to the limited menu of recommended foods and dishes. The diet for children with gluten intolerance should include a sufficient amount of gluten-free grain-based products. They provide children with carbohydrates, dietary fibers, vegetable proteins, fats, B vitamins, and minerals, e.g. potassium, magnesium, selenium, etc. In this regard, it is urgent to develop new types of specialized gluten-free products to expand the diet both in terms of nutritional value and taste diversity. Study objects and methods. The research is part of a project on the development of dry gluten-free mixes based on buckwheat and amaranth with fruit, vegetable, and berry raw materials. The new formulations are intended for children older than three years of age with gluten intolerance. The research objective was to study the main nutrients in amaranth and buckwheat flours. The study involved the method of infrared spectroscopy using a SpectraStar 2500 analyzer. The data obtained made it possible to calculate the nutritional and energy value of products based on amaranth and buckwheat flours, as well as fruit, vegetable, and berry powders intended for children older than three years of age with gluten intolerance. Results and discussion. Amaranth flour proved to be rich in protein (13.4%), lipids (5.1%), and ash (2.8%). Native buckwheat flour contained 7.5% of protein, 3.6% of lipids, and 1.4% of ash. The carbohydrate content appeared approximately the same in both samples (56–58%). The dry gluten-free mixes can serve as an important source of vegetable protein (up to 9.44 g per 100 g of the finished product), carbohydrates (up to 40.08 g per 100 g of the finished product, and energy (from 158.12 to 221.85 kcal per 100 g of the finished product). Conclusion. The high nutritional and biological value of amaranth and buckwheat flours, as well as fruit, vegetable, and berry powders, confirmed the prospect of using them as the main components for functional foods. Amaranth and buckwheat contain no gluten but are rich in protein, amino acids, saturated and unsaturated fatty acids, minerals, and biologically active elements, which makes them an important source of nutrition for children with gluten intolerance.

The diet of children with gluten intolerance should include a sufficient amount of gluten-free grain-based products that provide children with carbohydrates, including dietary fiber, vegetable proteins, fats, B vitamins, and mineral matters. This study is aimed at studying the content of the main food substances (proteins, fats, carbohydrates, as well as the total content of mineral matters, expressed by the parameter – ash content) in amaranth flour and flour from native buckwheat. Studies have shown that amaranth flour has a high protein content-13.4%, lipids-5.1%, and ash content - 2.8%. Flour from native buckwheat contains protein-7.5%, lipids-3.6%, the ash content of buckwheat flour was 1.4%. The carbohydrate content of both samples is approximately at the same level of 56-58%. Specialized products made from amaranth and buckwheat can become a source of deficient macro-and microelements, high-grade protein and other biologically valuable compounds.

Abstract-Gluten intolerance /allergies is now a silently rising problem world-wide. Gluten is a protein composite found in cereals, wheat, rice, barley and certain oat varieties. It also causes Celiac disease which is an autoimmune disease (most severe form of gluten intolerance), resulting from glutenintoleranceandisbasedongeneticintolerance. The only therapeutic treatment for the patients with gluten allergies and celiac disease is a strict gluten free diet. Rising demand for gluten free products is a task for the bakers and manufacturers to eliminate gluten completely from their products which is technically not possible. This draws the attention to the fact that mandatory analysis in this field is required. The aim of this work is to find a way to reduce the gluten content in the available materials, and also to find the source of gluten contamination after processing of raw materials. It wasnotedthatgarlicandsugarcontainingcombination were found effective and showed decrease in gluten content and that they were better additivities in the processing process than rest of others.

The effectiveness of treating gluten intolerance directly depends on the patient adherence to a gluten-free diet, which they often violate due to the limited range of recommended foods and dishes. First of all, this applies to children. The development of new types of gluten-free products using non-traditional grain raw materials has become particularly relevant, giving the possibility to expand the diet both in terms of nutritional value and taste diversity. Mainly due to the intake decrease of grain-based products, children are lack of such important minerals as potassium, magnesium, selenium, etc. The mineral elements contained in cereals are important for the growing child body, since they are involved in many important biochemical processes. The article purpose is to determine the minerals (Ca, Mg, K, Na, P, Fe, Cu, Zn, Mn, Se, Co, Pb, Ni, Mo, Cd, As, Hg) content in buckwheat and amaranth flour, as well as in products obtained from flour mixtures of these cultures. According to the obtained data on the macro-and microelements content in gluten-free products, a significant part of the minerals in the considered flour samples is potassium: 371 mg/100 g – for amaranth flour and 405 mg/100 g – for buckwheat flour. High magnesium content was in buckwheat (239.9 mg/100 g) and amaranth (202.5 mg/100 g) flour. There was a low calcium content in both samples: 69.0 mg/kg in amaranth and 62.0 mg/kg in buckwheat flour. Amaranth flour is superior to buckwheat in the content of trace elements such as copper (319 mcg/100 g), zinc (2495 mcg/100 g) and selenium (515.4 mcg/100 g). Buckwheat flour contains more phosphorus (263.3 mg/100 g), potassium (405.9 mg/100 g), magnesium (239.9 mg/100 g), and copper (334 mcg/100 g) than amaranth flour. According to the results obtained, amaranth and buckwheat flour can be classified as good sources of selenium – 515.4 and 404.0 mcg/100 g, respectively. The mineral substances content in pancakes made from mixtures of amaranth flour and native buckwheat flour decreased within 3.0–23.0 % of their content in the original flour. The calculation of the recommended daily requirement showed that consuming pancakes portion (45 g) by school-age children meet their daily need, %, on average: in magnesium – by 35.3; in potassium – by 9.5; in iron – by 26.4; in copper – by 19.6; in selenium – by 27.7.

The scientific review article allows to evaluate the relevance of scientific research of gluten-free bakery and confectionery products produced on the basis of secondary types of flour and flour mixtures, modern sources of non-traditional types of fruit and berry raw materials, innovative technologies, functional ingredients, designed to maintain the health of the population suffering from gluten intolerance. Much attention is paid to the use of amaranth seed flour in bread production, which has a higher biological value compared to traditional types of flour. Adding, along with amaranth flour, chufa tuber flour, carrot, rowan, pumpkin, apple and other powders to the dough can expand the diet of patients with symptoms of gluten intolerance. In particular, the apple powder contribute to the prevention of cardiovascular disease, excess weight, removal of heavy metals from the body, prevent the development of atrophy of the skeletal muscles, and carrot powder - speed recovery from a nervous breakdown, prolonged stress, strengthen the heart muscle, improve blood vessels, enhance immunity, prevent the development of atherosclerosis, hypertension, etc. The technology of production of gluten-free products based on amaranth seed flour mixed with corn or rice flour continues to be improved, which significantly increases the nutritional value of these products and expands the range of affordable gluten-free food products of domestic production. Another example is croissants baked on the basis of rice, buckwheat, flaxseed, almond and Teff flour. The analysis of organoleptic and physicochemical parameters showed that they meet the requirements of quality and high taste and aroma characteristics. Gluten-free bread based on chia flour, buckwheat flour, flax, soybean, amaranth, millet, tapioca, sorghum, peas, quinoa, rice and lupine flours contain a high amount of dietary fiber, positively influencing the quantitative and qualitative composition of intestinal microflora and helping to preserve the freshness of baked products. Despite the commonality of existing approaches in the production of gluten-free products, scientists suggest supplementing the existing recipes with secondary types of flour, fruit and berry and other functional components. Thus, the problem of using gluten-free flours in the production of functional products remains the object of increased scientific attention on the part of scientists, manufacturers and consumers.

One of the ways to improve public health with food is the industrial production of foods, the so-called “health” group, which currently includes functional and specialized products. Modern trend of the flour products market development is the expansion of gluten-free products segment. It should be noted that along with the target audience (people suffering from various forms of gluten intolerance), consumers of these products are adherents of "fashion trends". The chemical composition of this group of foods is characterized by the predominance of easily digestible carbohydrates and fats with a lack of proteins, vitamins and minerals, as well as fiber. Therefore, during a prolonged use of such foods the risk of deficiency states for individual macro- or micronutrients increases. Improving of the composition of gluten-free products can be achieved by introducing of non-traditional plant sources, such as amaranth grain, chufa tubers, fine vegetable powders, into the formulation. A special category of flour foods are products for herodietetic nutrition. One of the ways to increase the digestibility of mineral substances of bread, and calcium in particular, is the use of pre-germinated wheat as a prescription component.

Diet therapy is one of the main approaches to the treatment of a wide range of diseases of the digestive system. The treatment effectiveness of celiac disease depends on how strictly the patient adheres to a gluten-free diet. It is often disrupted due to the limited range of recommended foods and dishes, especially for children who are particularly sensitive to dietary restrictions. In this case, the development of new types of specialized gluten-free products is relevant, allowing to expand the diet both in terms of nutritional value and taste diversity. This study concerns the recipe developments of dry gluten-free mixtures using rice and amaranth with the inclusion of fruit and vegetable and berry raw materials intended for the nutrition of children over three years old suffering from celiac disease. When developing the recipes, researchers used various combinations of rice and amaranth flour, as well as fruit and vegetable powders. The rice flour composition varied in the range from 15 to 75%; amaranth – from 15 to 45%; fruit and vegetable and berry powders – up to 10%. The finished product was gluten-free cookies, muffins, pancakes made of rice and amaranth. Organoleptic evaluation showed that the studied samples of gluten-free cookies have high quality characteristics, have a pleasant taste and aroma. According to the calculated data, specialized gluten-free dry mixtures intended for children over three years with celiac disease can serve as an important source of: vegetable carbohydrates – from 26.81 to 55.19 g / 100g of finished products; protein – from 4.06 to 11.82 g/100g of finished products; dietary fiber – from 3.82 to 6.36 g/100g of finished products; and energy – from 158.12 to 333.96 kcal/100g of finished products) The developed recipess of gluten-free products can help to provide children with an adequate amount of nutrients and energy.

Gluten-free products based on starch and hydrocolloids are deficient in nutrients and do not contain pro-health substances. Therefore, they should be enriched in raw materials naturally rich in antioxidants, especially if they are intended for celiac patients, prone to high oxidative stress. Apart from the traditionally used pseudo-cereals, seeds, vegetables and fruits, innovative substrates such as the by-product (especially in Poland) dry apple pomace could be applied. The study material consisted of gluten-free bread enriched with apple pomace. The content of individual polyphenols, the content of total polyphenol and flavonoids, and also the antioxidant potential of the bread were determined by the UPLC-PDA-MS/MS methods. It was observed that apple pomace was a natural concentrate of bioactive substances from the group of polyphenols. In summary, gluten-free bread with 5% content of apple pomace showed the highest organoleptic scores and contained high levels of phenolic compounds. The values of total phenolic content, and the amounts of flavonoids, phenolic acids and phloridzin in this bread were 2.5, 8, 4 and 21 times higher in comparison to control.

The article highlights a complex of studies and a comparative assessment of flour of various varieties and hybrids of chia and sorghum. It was found that, in terms of their chemical composition, these crops are advisable to use as raw materials for the production of gluten free products. To live a full life, people with celiac disease must constantly consume gluten-free foods. Rice, buckwheat, millet, corn are considered safe, and amaranth, quinoa, sago, Setaria italica, sorghum are also less common in Ukraine. To obtain high-quality gluten-free products, it is important to choose the right raw materials and their ratio in chemical composition. Therefore, it is advisable to study and compare the chemical composition of sorghum and chia flour. The aim of the research was to study and compare the chemical composition of whole grain sorghum flour versus chia for use in the food industry as a source of gluten-free nutrition. The experimental part of the work was carried out during 2017–2019 in the hybrids of grain sorghum of Ukrainian (Lan 59), French (Targga) and American (Prime) selection and Spanish sage (chia) (Salvia hispanica) varieties: Salba, Tzotzol, Iztac. Whole grain sorghum and chia flours were obtained from their grains and various chemical constituents were determined. Comparative analysis of the chemical composition of sorghum and chia flour allows us to note that, on average, the protein content in sorghum was in the range from 9.53 to 10.6 g, in chia varieties from 14.98 to 16.52 g, which is on average five, 8 g more. The data on the determination of fats show that in the hybrid of sorghum of Ukrainian selection, this indicator was 2.8 g, French 1.24 g, and American – 3.3 g, as for chia, this indicator is much higher and varies by varieties from 30, 12 to 30.71 g. Starch is the main component of flour and in sorghum; its mass fraction is more in the Prime hybrid 63.7 g, Lan 59 – 63.1 g and the smallest amount in Targga – 62.7 g. It has been determined that grain sorghum and chia flour has a high content of B vitamins, which act as coenzymes of a number of metabolic processes. In addition to the vitamins listed above, sorghum flour contains vitamins B9, B5, B6 as well. Chia varieties have high levels of micro- and microelements. Key words: flour, vitamins, microelements, proteins, fats, carbohydrates, celiac disease, sorghum, chia.
