Необходимость разработки безглютеновых продуктов обусловлена ростом численности людей страдающих целиакией, распространенность которой составляет 1 случай на 100–200 человек населения. Решение проблем, возникающих при производстве безглютеновых мучных кондитерских изделий, делает актуальным поиск новых видов сырья, не содержащего глютен и способного улучшать потребительские свойства изделий. В качестве источника безглютенового сырья была выбрана гречневая мука (ГМ). Получено безглютеновое печенье из ГМ в сочетании с различными гидроколлоидами – камедями акации, трагаканта, гуаровой и ксантановой, которые по отдельности добавляли в образцы ГМ в количестве 1г/100 г, и исследовано его физико-химические и сенсорные свойства в сравнении с аналогичными свойствами печенья из пшеничной муки (ПМ). Установлено, что образцы ГМ с добавкой камедей имеют более высокое содержание влаги, а печенье, полученное из смеси ГМ с камедью по разработанной нами технологии, – большую толщину, массу и сниженную прочность при разрушении по сравнению с ГМ и печеньем, изготовленным из нее. При сенсорной оценке качества изделий, проведенной по девятибалльной гедонистической шкале, установлено, что самые высокие показатели качества имеет печенье из ПМ, самые низкие – печенье, приготовленное из ГМ. Внесение камедей улучшило сенсорные показатели изделий на основе ГМ. Лучшим признан образец печенья на основе ГМ с добавлением ксантановой камеди. Таким образом, использование гидроколлоидов улучшает водосвязывающую способность муки и сенсорные показатели изделия – цвет, аромат, вкус и дает возможность получить безглютеновое печенье достаточно высокого качества, сопоставимого с качеством печенья из пшеничной муки. The need to develop gluten-free products is due to the growing number of people suffering from celiac disease, the prevalence of which is 1 case per 100–200 people of the population. Solving the problems that arise in the production of gluten-free flour confectionery products makes it relevant to search for new types of raw materials that do not contain gluten and can improve the consumer properties of products. Buckwheat flour (BF) was chosen as a source of gluten-free raw materials. Gluten-free cookies from BF were obtained in combination with various hydrocolloids-acacia, tragacanth, guar and xanthan gums, which were separately added to BF samples in the amount of 1 g/100 g, and its physical and chemical and sensory properties were studied in comparison with similar properties of wheat flour cookies (WF). The purpose of this work is to obtain gluten-free cookies from BF in combination with various hydrocolloids – acacia gum, tragacanth, guar gum and xanthan gum, which were separately added to BF in the amount of 1 g/100 g, and to study its physical, chemical and sensory properties in comparison with similar properties of cookies from WF. It was found that the samples of BF with the addition of gums have higher moisture content, and the cookies obtained from a mixture of BF with gum according to the technology developed by us – a greater thickness, weight and reduced strength at destruction compared to BF and cookies made from it. In the sensory evaluation of the quality of products conducted on a nine-point hedonistic scale, it was found that the highest quality indicators are cookies made from WF, the lowest – cookies made from BF. The introduction of gums improved the sensory performance of BF-based products. A sample of BF-based cookies with the addition of xanthan gum was recognized as the best. Thus, the use of hydrocolloids improves the water-binding ability of flour and the sensory characteristics of the product – color, aroma, taste, and makes it possible to obtain gluten-free cookies of sufficiently high quality, comparable to the quality of cookies made from wheat flour.

Millet flour (water washed or alkali washed) was replaced with wheat flour (WF) at 0, 25, 50, 75, and 100% levels. Objectives of the research were to characterize the flour blends for their technical properties and to produce cookies with less or no gluten contents. All types of flour blends were evaluated for their pasting properties. The cookies were baked and evaluated for their textural and physical attributes. Inclusion of millet flour (both types) in wheat flour resulted in significant reduction in peak and final viscosities while setback viscosities were affected non-significantly. Pasting temperature was increased from 65 ℃ (100% wheat flour) to 91 ℃ (100% millet flour). The hardness of cookies was reduced in the presence of millet flour. Fracturability values of cookies with higher millet flour were higher as compared to control cookies (prepared from 100% wheat flour). Cookies prepared from blends having more that 50% millet flour were not much liked by sensory panelists. The phenolic contents of cookies containing higher levels of either water washed or alkali washed millet flour were found to be higher when compared to cookies prepared from plain WF (1.90 ± 0.14 mg gallic acid/g sample). The 2,2-diphenyl-1-picrylhydrazyl activity (%) of cookies ranged from 16.39 ± 0.34 (100% water washed millet flour) to 10.39 ± 0.26 (100% WF; control). The study will help the non-coeliac people to consume low gluten (≈1.6–6.5%) or gluten intolerant people to consume gluten-free cookies (0%) from millet flour having abundant of antioxidants and health-promoting polyphenols.

Forty-six strains of sourdough lactic acid bacteria were screened for proteolytic activity and acidification rate in gluten-free (GF) flours. The sourdough cultures consisted of Lactobacillus sanfranciscensis LS40 and LS41 and Lactobacillus plantarum CF1 and were selected and used for the manufacture of GF bread. Fermentation occurred in two steps: (i) long-time fermentation (16 h) and (ii) fast fermentation (1.5 h) using the previous fermented sourdough as inoculum (ca. 43%, wt/wt) with Saccharomyces cerevisiae (baker's yeast). GF bread started with baker's yeast alone was used as the control. Gluten was added to ingredients before fermentation to simulate contamination. Initial gluten concentration of 400 ppm was degraded to below 20 ppm only in the sourdough GF bread. Before baking, sourdough GF bread showed phytase activity ca. sixfold higher than that of GF bread started with baker's yeast alone. Atomic absorption spectrophotometric analysis revealed that the higher phytase activity resulted in an increased availability of free Ca2+, Zn2+, and Mg2+. The concentration of free amino acids also was the highest in sourdough GF bread. Sourdough GF bread had a higher specific volume and was less firm than GF bread started with baker's yeast alone. This study highlighted the use of selected sourdough cultures to eliminate risks of contamination by gluten and to enhance the nutritional properties of GF bread.

Tanaman talas bogor (Colocasia esculentum (L) Schott) sangat mudah dibudidayakan di daerah tropik dan sub-tropik, termasuk Indonesia. Umbi talas bogor kaya akan karbohidrat, sehingga dapat digunakan sebagai sumber energi yang potensial bagi manusia melalui berbagai proses modifikasi. Tujuan dari penelitian ini adalah memperbaiki kualitas tepung umbi talas bogor dengan mengkaji pengaruh konsentrasi suspensi, katalis, oksidator, dan temperatur dari proses modifikasi dengan cara oksidasi menggunakan larutan hidrogen peroksida (H2O2). Variabel yang dikaji adalah suspensi tepung dengan air (40, 30, 20, dan 10%), waktu reaksi (30, 60, 90, dan 120 menit, konsentrasi katalis (0; 0,1%; 0,2%), konsentrasi oksidator (1%, 2% dan 3%) dan temperatur (30; 40; 50oC). Hasil penelitian menunjukkan bahwa penggunaan konsentrasi suspensi 40% , konsentrasi katalis 0,1%, konsentrasi H2O2 2% dan temperatur 30oC pada waktu oksidasi 30 menit memberikan hasil yang paling optimum ditinjau dari daya kembang (swelling power) dengan nilai 7g/g dan kelarutannya dalam air yaitu 4% dengan mempertimbangkan aspek teknis dan ekonomis dari proses. Hasil penelitian ini menunjukkan bahwa penggunaan H2O2 sebagai oksidator cukup efektif dalam meningkatkan nilai daya kembang tepung talas bogor yang sebelumnya hanya 4,3 g/g menjadi 7 g/g, dimana nilai tersebut telah masuk dalam rasio daya kembang tepung terigu yaitu 6,8-7,9 g/g. Namun oksidator H2O2 tidak cukup efektif dalam meningkatkan nilai kelarutan tepung dalam air yang sebelumnya hanya 2% menjadi 4%, dimana nilai tersebut masih dibawah rasio kelarutan tepung terigu yaitu 6,3-7,3%. Selain itu uji organoleptik pada kue kering berbahan baku tepung umbi talas bogor teroksidasi menunjukkan kelemahan berupa rasa yang agak pahit dan tekstur yang terlalu rapuh dibandingkan dengan kue kering yang menggunakan bahan baku tepung terigu.Bogor taro (Colocasia esculentum (L) Schott) is one of the local resources which can be used as raw material for flour and starch production. They are easy to cultivate in tropical and sub-tropical area such as Indonesia. Tubers of Bogor taro contain a lot of carbohydrates and the flour can be modified using several technique of modification in order to achieve the similar content and properties as wheat flour. The objective of this research was to upgrade the quality of tuber Bogor taro flour by studying the effect of suspension consistency (40; 30; 20;10%), concentration of catalyst (0; 0.1%; 0.2%) and H2O2 (1%; 2% and 3%) as oxidizer and temperature of oxidation process (30; 40; 50oC). The results showed that the use of 40% suspension consistency, 0.1% catalyst concentration, 2% H2O2 concentration and 30oC of oxidation temperature at 30 minutes gave the most optimum results in terms of swelling power with 7g/g and water solubility 4% with taking the technical and economic aspects of the process as consideration. Swelling power and water solubility of modified tuber of Bogor taro flour were higher compared to the native ones, which successively 4.3 g/g and 2%. However, in organoleptic analyses showed that the cookies made from modified flour of Bogor taro tuber still have weaknesses such as a bitter taste and fragile textures compared to the cookies made from wheat flour.

The development and study of new gluten-free foods of high quality that are suitable for people with celiac disease is necessary since there is increasing frequency of people who have been found to be allergic to proteins in wheat flour. Rice is one of the most used cereals in these special foods elaborations. However, replacement of wheat flour by rice flour usually leads to a noticeable decrease in the quality of the products discussed in this study. This work studied the individual and combined influence of xanthan gum (XAN), emulsifier, pregelatinizated starch, and transglutaminase on quality of rice yellow layer cake (YLC) by means of a systematic study based on a two-level half-fractional factorial experimental design. Size and shape, texture, color, crumb grain profile and sensory acceptance were evaluated in YLC. XAN, white egg proteins, and emulsifier showed significant positive effects on volume, texture and crumb grain characteristics. The feasibility of rice YLC reaching acceptable levels of customer satisfaction was demonstrated.

Abstract This study evaluated the effect of addition of Brachystegia eurycoma flour (BEF), a natural source of hydrocolloids, on the physicochemical properties of whole millet flour (WMF) and the sensory attributes of its gluten-free bread. BEF and sodium carboxylmethyl cellulose (a reference hydrocolloid) were added to WMF at 1.5 and 3% proportions, and breads were baked from the blends. Wheat flour (100%CWF) bread served as the control. Amylose level decreased significantly (p < 0.05), while water absorption capacity, peak and final viscosities of the blends increased with increasing proportion of BEF. The 100%CWF bread had better sensory qualities than WMF-BEF breads. Hence, BEF improved the physicochemical properties of WMF-BEF blend, but did not alter the sensory qualities of its gluten-free bread.

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.

The paper considers how gluten-free flours, in particular, those made from coconuts and brown rice, can be used in  the  technology of gluten-free chocolate muffins in order to expand the  range of special purpose products. Studies by domestic and foreign authors dedicated to using different flour types in today’s gluten-free technologies have been analysed. It has been proved that wheat  flour  can be fully replaced with gluten-free flour mixtures in the recipe of chocolate muffins. Analysis of the chemical composition of  coconut flour has shown its higher fat content, compared with wheat flour, and twice as much protein and dietary fibre (18%). Coconut flour exceeds wheat flour not only in the main macronutrients, but also in the content of the main minerals. Brown rice flour, too, contains more fats and vitamins of the B-group than wheat flour does, and is a source of sodium, magnesium, phosphorus, silicon, and sulphur. It contains up to 80% of starch and, like coconut flour, is gluten-free. Replacing wheat flour in the classical muffin recipe with mixtures of coconut and brown rice flours in the ratios 30:70, 40:60, and 50:50 reduces the moisture content and density of the dough. The moisture content in the finished muffins, too, is lower by 0.7, 1.2, and 1.5% respectively. It has been confirmed that if the gluten-free flour mixture contains over 50% of coconut flour, it reduces the specific volume of resulting muffins and worsens their quality parameters. The Harrington method was used to estimate the comprehensive quality index of the chocolate muffins. This has shown that full substitution of wheat flour for a mixture of gluten- free flours in the ratio 40:60 (coconut flour:brown rice flour) allows achieving the best-balanced sensory characteristics. Gluten-free muffins have a pleasant brown colour of the crust, their crumb is quite soft, homogeneous, and porous, with a balanced taste and an aroma of cocoa combined with light coconut notes.
