Effects of partial (50%) and total replacement of wheat flour with black rice flour on the phytochemical, physico-chemical, sensorial, and textural properties of muffins were studied. Partial or total replacement of wheat flour with black rice flour in muffins improved their nutritional and antioxidative properties with a positive effect on microbiological and color stability during the storage period in accelerated conditions. The low gluten muffins had an anthocyanin content of 27.54 ± 2.22 mg cyanidin-3-glucoside (C3G)/100 g dry weight (DW), whereas the gluten free muffins had 46.11 ± 3.91 mg C3G/100 g DW, with significant antioxidant values. Retention of 60% and 64% for anthocyanins and 72% and 80% for antioxidant activity after baking was found. The fracturability and hardness scores increased with the addition of black rice flour, whereas firmness and chewiness increased for gluten free muffins. The confocal analysis revealed a tendency of glucidic components to aggregate, with gathers of small bunches of black rice starch granules comprising anthocyanin. The results allowed designing two new value added bakery products, low and free gluten muffins, with significant high amounts of bioactive compounds, suggesting the functional potential of black rice flour.

The aim of this study was to develop gluten-free bread formulations based on small broken riceberry flour, by using different ratios of rice flour and xanthan gum. Small broken riceberry and rice flour could be classified as low in amylose content (15.70 g and 20.50 g/100 g dry matter for small broken riceberry and rice flour, respectively). Additionally, small broken riceberry flour contained a total phenolic and total anthocyanin content approximately 500 times higher than that of rice flour. The addition of increased amounts of small broken riceberry flour and xanthan gum resulted in darker coloured gluten-free bread. However, there was no significant difference regarding moisture and specific volume. The increase of small broken riceberry flour and xanthan gum also led to a significant increase in the firmness of bread crumbs. The sensory evaluation showed differences in flavour, texture and overall liking, since adding small broken riceberry flour tended to make gluten-free bread more favourable. Bread containing rice flour and small broken riceberry flour in the ratio of 30:70 and 1.0% xanthan gum was selected on the basis of the sensory quality. Moreover, such bread also contained high levels of total phenolic and anthocyanin content.

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 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.

Background. Flour confectionery in Ukraine is in high demand, it’s made gluten-free mainly using corn and rice flour, rarely buckwheat. In our opinion, an inte­resting alternative to these types of flour will be to use sesame flour in the recipe and technology of gingerbread products, due to its convenience and unique taste. We have not found any research on the use of sesame flour in the technologies of gingerbread flour confectionery in available sources. The aim of this research is to scientifically substantiate and develop the techno­logy of gluten-free gingerbread with a complete replacement of wheat with sesame flour. Materials and methods. The object of research is the technology of gingerbread using gluten-free finely ground sesame flour. As a control sample, high-grade wheat flour was used for the preparation of children’s gingerbread by custard. The quality of gingerbread is determined according to DSTU 4187:2003 (State Stan­dards of Ukraine). Organoleptic evaluation of the samples was performed on a 5-point scale. The calculation of nutritional value (proteins, lipids, carbohydrates, dietary fiber), and the content of minerals is carried out according to the tables of chemical composition. Results. With the help of test doughs, it was found that in the recipe of children’s gingerbread it is possible to completely replace wheat flour with sesame and "dry perfume" (a mixture of spices) with nutmeg. According to organoleptic parameters of two types of gingerbread from wheat and sesame flour, the latter were less porous, but had a pleasant rich taste of sesame and nutmeg aroma. As a result, the identified shortcomings do not have a significant impact on the overall quality of gluten-free products. The technological scheme of preparation of "Sesame" gingerbreads with the use of sesame flour and nutmeg has been developed. The chemical composition, mineral content and energy value of control and deve­loped gingerbreads were calculated. The latter had better nutritional and biological value. Conclusion. The technology of gingerbread dough and gingerbreads with the use of sesame flour and nutmeg has been developed, which improves the organoleptic and physicochemical parameters of the new "Sesame" gingerbreads, makes their taste more expressive and enriches them with useful microelements. By replacing wheat flour with sesame, the finished products do not contain gluten and can be recommended to certain categories of consumers who suffer from diseases associated with wheat protein intolerance and allergy to it.

The present study was undertaken to evaluate the effect of different levels of wheat flour on the quality characteristics of chicken meatball. Wheat flour which acts as a binding agent of meatball except for control group T1. The meatballs were formulated having 0%, 5%, 10% and 15% wheat flour. The sensory (colour, flavour, texture, juiciness, tenderness, overall acceptability), physicochemical (proximate analysis, pH, cooking loss), biochemical (TBARs, POV, FFA) were analyzed. Treatments were analyzed in a 4×3 factorial experiment in CRD replicated three times per cell. Wheat flour inclusion in meatballs increased cooking yield by reducing weight loss from 27.06 to 26.49%. Among four treatments most preferable colour, odour, tenderness, juiciness was observed significantly (p<0.05) at 15% wheat flour group and the less preferable colour was observed from the control group. The preferablecolourwas observed at 0 days and less preferable colour at 30 day. Meatballs made with the addition of 15% wheat flour had the highest tenderness, overall acceptability, raw pH, cooked pH and lower DM, ash, PV and TBA & showed significant value (p<0.05) The cooked pH was decreased with the increased storage period. Meatballs with wheat flour inclusions at 15% were most acceptable. It is recommended that further studies of the wheat flour inclusion in meatballs production be carried out to ensure the availability of cheaper, nutritious and acceptable convenience food in the Bangladeshi market.SAARC J.

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.
