Gluten free (GF) bread was made from rice flour and fermented cassava flour. Fermented cassava flour (FERCAF) was produced using a specific design of closed and circulated fermenter, which resulted on a white and neutral aroma flour. However, FERCAF did not have structural component (such as gluten) to provide dough's viscoelasticity and ability to retain gas to hold the volume of bread after baking. Hydrocolloids were added to FERCAF based GF bread to increase water binding of dough. This research aimed to investigate the effect hydrocolloids addition on the characteristics of GF bread made from rice flour and fermented cassava flour (FERCAF). Effect of hydrocolloids to flour ratio (2 %, 3 % and 5 %-wt) and types of hydrocolloid (xanthan gum, agar, and carrageenan) on specific volume of bread, bake loss, bread texture, and microstructure of the bread were investigated. Bread textures were measured using Texture Profile Analyzer (TPA), and microstructure was analysed by SEM. Data experiment showed that addition of hydrocolloids improved GF bread characteristics, specifically increased volume specific, increased porosity, and reduced hardness of GF bread.Keywords: gluten-free bread; cassava; fermented cassava flour; Fercaf; hydrocolloids

Research on processing of crispy baby tilapia (Oreochromis niloticus) was conducted to obtain type and proportion of flour on this product with central composite design method. This research used 6 types of flour, namely wheat flour, rice flour, potato flour, tapioca flour, corn flour and baking powder. Baby tilapia used for this research were 30-40 day old, 2-3 cm long. Parameters observed were sensory (appearance, odor, taste, texture, overall acceptance) and crispness for the physical parameter. The results showed that only two out of six variables gave big effect on the tested response i.e potato and rice flour. Those two variables were then optimized with central composite design method to obtain the best product. The optimization process demonstrated that the optimum amount of potato and rice flour were 58-60 g (22.16-22.92%) and 40-60 g (15.28-22.92%), respectively.

In this study, response surface methodology based on simplex- centroid design was used to optimize the gluten-free bread formulation with rice flour and cassava starch as independent variables. Bread formulations were evaluated by physicochemical analysis and descriptive sensory analysis encompassing appearance, structure, texture, and aroma parameters by a trained sensory panel. The five formulations composition showed statistical differences concerning aw, lipid and protein content.  Carbohydrate was significantly correlated with specific volume and lipids with protein. Overall, rice flour's addition improved lipid and protein, whereas further rises in cassava starch allowed developing bread with higher specific volume and sensory scores. The optimum combinations of the variables to maximize scores of porosity, texture, elasticity, and protein content, should be obtained with 51.75% of rice flour and 48.25% of cassava starch. The use of the simplex-centroid design and the response desirability function in the optimization was useful for evaluating the influence and potential of the binary mixture of rice flour and cassava starch on the sensory quality and chemical characteristics of gluten-free bread. These research findings open the scope for further investigation of rice flour and cassava starch and their useful application in gluten-free bread processing.

Исследована возможность использования полуобезжиренной льняной муки (ПЛМ) для улучшения качества и повышения пищевой ценности безглютеновых хлебобулочных изделий. В процессе исследования выпекали хлеб из рисовой муки с добавлением 4, 6, 9 и 11% ПЛМ. Контролем служил хлеб без добавления льняной муки. После выпечки определяли физико-химические показатели качества образцов рисового хлеба с ПЛМ. Установлено, что с увеличением содержания ПЛМ влажность в образцах хлеба снизилась на 0,4–5,7%; кислотность мякиша увеличилась на 57–185,7%. Удельный объем и пористость опытных образцов хлеба с добавлением ПЛМ в количествах 4 и 6% увеличились по сравнению с контролем на 9,1–13,6% и 3,21–8,1% соответственно, однако при увеличении дозировки льняной муки свыше 6% эти показатели снизились на 4,5–14,1% и 1,6–6,5% соответственно. Количество клетчатки при добавлении 6% ПЛМ увеличилось до 1,8%; белка – до 2,9%. Энергетическая ценность хлеба из смеси рисовой муки и ПЛМ осталась на уровне энергетической ценности хлеба из рисовой муки. Рекомендовано применение ПЛМ при производстве безглютенового хлеба из рисовой муки. Определена дозировка ПЛМ – 6% в смеси с рисовой мукой. The possibility of using semi-fat-free linen flour (SFF LF) to improve the quality and nutritional value of gluten-free bakery products has been studied. During the study, bread was baked from rice flour with the addition of 4, 6, 9 and 11% SFF LF. The control served the bread without adding linen flour. After baking, the physicochemical parameters of the quality of rice bread samples with SFF LF were determined. It is established that with increase in the content of SFF LF moisture content in samples of bread was down 0,4 to 5,7%; the acidity of the crumb increased by 57–185,7%. The specific volume and porosity of bread samples with the addition of SFF LF in quantities of 4 and 6% increased compared to the control by 9,1–13,6% and 3,21–8,1%, respectively, but with an increase in the dosage of linen flour over 6%, these indicators decreased by 4,5–14,1% and 1,6–6,5%, respectively. The amount of fibre with the addition of 6% of SFF LF increased to 1,8%; protein – to 2,9%. The energy value of bread from a mixture of rice flour and SFF LF remained at the level of energy value of bread from rice flour. The use of SFF LF in the production of gluten-free bread from rice flour is recommended. The dosage of SFF LF – 6% in a mixture with rice flour was determined.

This study aimed to perform a systematic review on gluten-free bread formulations using specific volumes as a quality indicator. In this systematic review, we identified 259 studies that met inclusion criteria. From these studies, 43 met the requirements of having gluten-free bread with a specific volume greater than or equal to 3.5 cm3/g. Other parameters such as the texture profile, color (crumb and crust), and sensory analysis examined in these studies were presented. The formulations that best compensated the lack of the gluten-network were based on the combination of rice flour, rice flour with low amylose content, maize flour, rice starch, corn starch, potato starch, starch with proteins and added with transglutaminase (TGase), and hydrocolloids like hydroxypropylmethylcellulose (HPMC). Of the 43 studies, three did not present risk of bias, and the only parameter evaluated in common in the studies was the specific volume. However, it is necessary to jointly analyze other parameters that contribute to the quality, such as texture profile, external and internal characteristics, acceptability, and useful life of the bread, especially since it is a product obtained through raw materials and unconventional ingredients.

Some plants, roots or tubers have been used as possible cereal substitutes in gluten-free cookies. Chayotextle is rich in starch and other compounds that could make it a potential ingredient for products aimed at the celiac population. In this study, the effect of different mixtures of rice flour (RF) and Chayotextle flour (CF) on the final properties of cookies and the prebiotic capacity when adding agave fructans (AF) was evaluated. Flour properties (water and oil absorption, emulsifying capacity) and cookies (diameter, thickness, specific volume, color, hardness and prebiotic capacity) were determined. CF presented higher emulsifying capacity, absorption of water and oil (27.1 %, 66.22 % and 95.93 %, respectively). The cookies with CF and AF reached the highest values in physical properties (65.10-66.82 mm in diameter, 9.36-10.04 mm thickness, 1.72-2.07 mL/g specific volume and 201.82 N in hardness). CF and the CF-AF formulation showed ability promoted the growth of both strains studied: Lactobacillus acidophilus LA-3 and Bifidobacterium animalis ssp. Lactis, reaching values of up to 9.82 log10 CFU/g and 9.85 log10 CFU/g (CF) respectively, in a period of 24 h. The CF and the addition of FA improved the properties of the cookies and proved to be a possible prebiotic source.

The gluten-free pasta (GFP) has a higher cost and is often brittle, pale, and poorly balanced in macro and micronutrients when compared to wheat-based pasta. This study aimed to use the biofortified sweet potato flour, a natural source of color and provitamin A ingredient, with rice flour, hydrolyzed soy protein concentrate, and carboxymethyl cellulose gum to produce GFP, using a central composite rotatable design with three factors (23) and the central point. The GFP were evaluated by instrumental color analysis, and visual analysis of technological characteristics (presence of cracks, defect, and shape aspect), used for selection. Three GFP were selected: E1, E2 and E12, which showed absence of breaks or defects and an intermediate aspect after cooking, which were submitted to nutritional, functional and sensory evaluations. These GFPs presented levels of β-carotene of 135.22, 292.04 and 147.54 µg/g (dry basis), respectively, and showed sensory overall liking means in the acceptance region (>4.5) with no significant differences among them. According to the penalty analysis, the parameters color and consistency penalized these averages. Therefore, optimizing the ingredients’ concentrations improved the nutritional value and the sensory acceptability of GFP.

The use of hydrocolloids in gluten-free breads is a strategy to improve their quality and obtain products with acceptable structural and textural properties. Hydration level (HL) optimization is important to maximize the hydrocolloids effects on dough and bread quality. This study evaluated the optimum hydration level (OHL) for gluten-free breads prepared with different starch sources (rice flour or maize starch) and hydroxypropyl methylcellulose (HPMC) in comparison with psyllium husk fibre and xanthan gum. Breads with the same final volume and the corrected hydration (CH) were evaluated. The hydration is a key factor that influences the final characteristics of gluten-free breads. Breads made with HPMC had greater dependence on the HL, especially for preparations with maize starch. Psyllium had similar behaviour to xanthan with respect to specific volume and weight loss. Breads manufactured with maize starch and HPMC had low hardness due to their great specific volume. However, in breads made with rice flour, the combined decreased hydration and similar specific volume generated a harder bread with HPMC than the use of psyllium or xanthan. Breads made with HPMC presented higher specific volume than the other hydrocolloids, however combinations among these hydrocolloids could be evaluated to improve gluten-free breads quality.

The aim of this study was to develop gluten-free breads using the flours of Andean native grains. The following native grains were used: quinoa (Chenopodium quinoa) Pasankalla variety, kiwicha (Amaranthus caudatus) Centenario variety, kañiwa (Cheopodium pallidicaule) Illpa Inia variety and tarwi (Lupinus mutabilis) Blanco de Yunguyo variety. The formulations of the breads with Andean grains flours were optimized using the Mixture Design and the Central Composite Rotational Design, analyzing the dough’s textural properties (firmness, consistency, cohesiveness and viscosity index), specific volume and crumb texture. Potato starch and xanthan gum were used in the preparation of the breads. The optimized formulations of the gluten-free breads with Andean grain flours were composed of quinoa (46.3%), kiwicha (40.6%), kañiwa (100%) and tarwi (12%) flours. The gluten-free breads developed showed acceptable specific volume and low crumb firmness and could help to improve the nutrition of celiac patients.

The percentages of soy flour (X1) and dry milk (X2) were varied for the production of gluten-free bread to optimize batter softness (Y1), specific volume (Y2), crumb grain score (Y3), bread score (Y4) and bread protein content (Y5). A central composite design was used and second-order models for Y1 were employed to generate response surfaces. When bread protein content was decreased from 10 to 3%, specific volume increased from 3.2 to 4.6 cm3/g and bread score increased too. Nevertheless, the highest crumb grain score was obtained at 7.3% of bread protein content. The results demonstrated that a gluten-free bread can be prepared by adding 7.5% soy flour and 7.8% dry milk to a previously developed formulation, increasing its protein content from 1 to 7.3% and modifying in a small degree, its sensory quality.
