The use of wheat hydrolyzate in the technology of extruded gluten-free cereal snacks

Разработана технология экструдированных безглютеновых снеков с использованием в качестве частичной замены безглютенового сырья - рисовой муки ферментализатом пшеницы, глютен которой предварительно прогидролизован комплексом протеолитических и амилолитических ферментных препаратов. Иммуноферментным методом анализа подтверждено соответствие содержания глютена в сырье и гидролизате требованиям Технического регламента Таможенного союза 027/12, предъявляемым к безглютеновой продукции. Полученный гидролизат насосом-дозатором подавался в камеру экструдера в количестве до 35 % к массе перерабатываемой сухой смеси на основе рисовой муки. Было изучено влияние дозировки ферментолизата пшеницы на режимные параметры экструзии, изменение структурно-механических, цветовых и органолептических характеристик полученных образцов снеков. Установлено, что с увеличением содержания гидролизата в перерабатываемой смеси возрастает влажность экструдата, отобранного после режущего устройства, в процессе экструдирования снижаются значения момента сдвига, давления, температуры экструзии, а также удельного расхода. Изменение количества вносимого ферментолизата пшеницы значимо изменяло структурно-механические показатели экструдатов. В снеках без гидролизата значение твердости составляло 6,7 Н, а с добавлением ферментолизата отмечалось увеличение до 14,6 Н. Обратная тенденция установлена для показателей коэффициента взрыва и количества микроразломов, значения которых с ростом дозировки гидролизата снижались с 8,6 до 4,1 и с 14,3 до 6,0 соответственно. Отмечено увеличение значений хроматических составляющих цвета снеков при добавлении ферментолизата в экструдируемую смесь, при этом варьирование его дозировкой не оказывало значимого влияния на изменение цветовых характеристик. По результатам дегустации более высокие оценки получили образцы снеков с добавлением 15-20 % гидролизата пшеницы. Whole wheat flour has been hydrolyzed by a complex of proteolytic and amylolytic enzymes in order to eliminate gluten and allergenic peptides. The resulting hydrolysate was tested in gluten-free snack extrusion technology as a substitute for rice flour. The enzyme-linked immunosorbent assay confirmed the compliance of the gluten content in raw materials and hydrolysate with the requirements of the Technical Regulations of the Customs Union 027/12 for gluten-free products. The resulting hydrolysate was fed by a metering pump into the extruder chamber in an amount up to 35 % by weight of the processed dry mixture based on rice flour. The effect of the dosage of wheat hydrolysate on the operating parameters of extrusion, the changes in the structural, color and organoleptic characteristics of the snacks was studied. It has been established that the moisture content of the extrudate taken out after the cutting device increases with an increase in the content of hydrolysate in the processed mixture. At the same time, the values of torque, pressure, extrusion temperature, as well as specific mechanical energy decreased. The content of hydrolysate in the mixture significantly influenced the structural properties of snacks. The hardness value of the snacks without hydrolysate was 6.7 N. It increased to 14.6 N with the addition of hydrolysate up to 35 %. The opposite trend was established for sectional expansion index and the number of fractures, the values of which decreased from 8.6 to 4.1 and from 14.3 to 6.0, respectively. Adding wheat hydrolysate was significant in changing the color characteristics of the extrudates, while the dosage value did not have a significant effect on the color of snacks. According to the results of sensory analysis, samples of the extruded snacks with the addition of 15-20 % wheat hydrolysate received higher scores.

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 aglutenics biscuits are intended to those persons who are suffering due to gluten intolerance, also named celiac disease. The fabrication technologies of the aglutenics products can be developed in on two ways: by separating the gluten from the grain or by replacing the grain flour with other types of gluten less flour, in case of bakery and pastry products. In this experiment, the gluten-free biscuits were obtained from the following flours mixture: maize flour (MF), rice flour (RF) and soybeans flour (SF). Other raw materials were used, such as: palmtree oil, honey, maize starch, eggs, sugar powdered, vanilla essence and sodium bicarbonate. Four experimental variants (gluten-free biscuits) were obtained by varying the proportion of flours ; these variants were coded as follows T1, T2 T3 and T4. The optimization of the aglutenics biscuits manufacture recipe was realized through sensory analyze, using the hedonic test (9 point scale). Samples of biscuits was subjected to the following physico-chemical analysis: moisture content, alkalinity, total carbohydrate content, total fat and protein content. Also the physical properties (length, width, thickness, weight and spread ratio) were determined in order to asses the blending influence on the biscuits quality. The blend with flour levels 30:30:40 (MF:RF:SF) led to the highest acceptability.

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.

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.

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.

Gluten free products remain the cornerstone for celiac patients. Insufficiency, poverty and little offered about gluten free products (quality and quantity) represented a high obstacle for Egyptian celiac patients. Therefore, the purpose of this research is to modify a single screw extruder to produce gluten–free pasta (GFP) (tagliatelle type). The GFP was made from corn flour under screw rotation speed (N) of 10, 25 and 50 rpm at 40, 65, 90 and 115 ºC of barrel temperature (BT). Extruder performance was evaluated as specific mechanical energy (SME) and expansion ratio (Er). The cooking quality of GFP as optimum cooking time (OCT), cooked yield (CY), swelling (Sw), cooking losses (CL) and sensory characteristics (appearance, colour, taste, mouth feel and overall acceptability) were evaluated. The better results of the GFP sensory evaluation were obtained at BT= 80 ºC, N =25 rpm and Er ≈ 1.38 with OCT ≈ 3.3 min, CY= 196%, Sw = 210% and CL= 16.3%. All parameters were given a direct proportion with processing variables N and BT, except CL. Furthermore, it can be predicted cooking properties values for GFP by SME value using the following equation; SME » 1.8675 (Er) + 0.8037 » 0.0608 (OCT)1.5984 » 8×10-17 (CY)6.7878 » 2×10-9 (Sw)3.494 » -0.0306 (CL) + 0.7877.

Abstract People suffering from the celiac disease have to apply a strict gluten-free diet because this is the only effective management. Nowadays, the increasing incidence of celiac disease promotes worldwide interests for various desirable gluten free products. As a consequence, food processing researchers have been seeking to develop high-quality gluten-free bread. Cereals having gluten such as wheat must be removed from the diet for the clinical and histological improvement. So, the purpose of this study was to determine the physical, chemical and sensory properties of gluten-free bread produced with barley (T1), corn (T2) and rice (T3) flours instead of wheat flour, using the 1.5 % xanthan gum. The chemical and sensory attributes of bread were evaluated by AOAC method and hedonic test, respectively. Obtained results showed that sample T3 had the highest contents of crude protein (7.94%), ash (2.51%) and carbohydrate (78.31%) as compared to other samples, while fat was lower (2.01%). Regarding moisture, breads prepared with the three different flours were not statistically different at the significance level of p<0.05. However, they differed significantly regarding the specific volume and bake loss. Data also revealed that gluten-free bread, treatment T3 presented the best parameters, being preferred by the sensory evaluation panel, followed by treatment T1 and T2. The overall assessment pointed that the resulting breads treatment T3 was best for all physico-chemical characteristics and, in general, resulted in good sensory behavior, indicating that it could be a promising alternative to wheat flour.
