Different Origins

Addition of hydrocolloids (H/C) in gluten-free (GF) bread formulation is necessary in order to act as polymeric substances that should mimic the viscoelastic properties of gluten and increase the dough’s gas-retaining ability. The properties of H/C vary depending on their origin and chemical structure. Addition of H/C (hydroxypropylmethylcellulose (HPMC), xanthan, κ-carrageenan and guar gum) of different origins at 1%, 1.5% and 2% (w/w) in GF formulations based on corn starch and rice flour was carried out to investigate the effects on dough rheology and bread quality. The consistency, viscosity and thermal properties of doughs were evaluated. According to results, 1% and 1.5% addition of H/C (except from xanthan) contributed to bread with higher loaf volume and better color compared to control GF bread as well as to increased shelf life due to its moisture-absorption ability. Sensory evaluation by a trained panel revealed a preference for bread containing 1.5% HPMC because of its loaf volume, appearance and firmness characteristics. The micrographs of the dough showed a continuous matrix between starch and HPMC obtaining a more aerated structure.

The article presents the results of a study on the development of a recipe for semi‑finished custard based on gluten‑free raw materials. The ratio of components in the gluten‑free mixture was optimized using the regression analysis method. The influence of gluten‑free raw materials on the rheological properties of the semi‑ finished product is studied. The variants of the experiment differed in the composition of the composite mixture (the ratio of corn, rice flour and corn starch). The chemical composition and the ratio of the components of the mixture determine the rheological properties of the semi‑finished product. The experimental version with the ratio of rice flour, corn flour and corn starch 50:40:10 most corresponds to the rheological properties of the control version and is characterized by high consumer properties.

In the food industry, the addition of flavours is used to reinforce the aroma profile of different goods. However, interactions between starch and aroma compounds can occur, and this can impact upon aroma release and perception. In the present study, we have investigated the influence of starch type on aroma release from starch-aroma systems. The food model system used was composed of an aqueous starch dispersion (1 g dry starch/100 g dispersion) and 10 aroma compounds (ethyl butanoate, ethyl 2-methylbutanoate, ethyl 3-methylbutanoate, ethyl pentanoate, methyl hexanoate, ethyl hexanoate, methyl ethyl propanoate, hexyl acetate, 3-hexenol, and phenyl methyl acetate). Different commercially available starches were used: Amilogels P, K, PDP, G, MVK, HP, OK and HPW, and carrageenan (Amilogel CAR) and guar gum (Amilogel GG). Aroma release from these starch-aroma systems into the gas phase above food (headspace) were monitored by GC-MS analysis with a solid-phase micro-extraction technique. The smell of the starch-aroma system was also evaluated sensorially by a trained panel. The release of aroma compounds from the different starch-aroma systems was statistically significant (<I>P</I> < 0.0001) for all of the aroma compounds, with the exception of ethyl pentanoate. A correlation between the concentration of individual aroma compounds in the headspace and the sensory evaluation (smell) was seen. Starch-aroma systems comprising corn starch (Amilogel G), physically modified starches that are soluble in cold water (Amilogels K, PDP), and hydroxypropyl distarch phosphate (Amilogels HP) had sensorially superior smells compared to the other types of starches tested. At the same time, the headspace GC-MS analyses showed ethyl butanoate, ethyl 2-methylbutanoate, ethyl 3-methylbutanoate and ethyl pentanoate to be at the highest concentrations, which are all typical aroma compounds of strawberry fruit, and which also have low perception thresholds. Dextrin-roasted starch, guar gum and carrageenan provided the lowest sensory scores, although in contrast, they more strongly retained these aroma compounds.

<p>Gluten-free savory snacks were formulated and evaluated to offer nutritious treats for all and healthy option for gluten intolerance individuals. Four kinds of savory snacks (gluten-free, whole grains with fresh vegetables, low in fat and salt) were developed using base formulation (BF) of brown rice flour (45%), sorghum flour (20%), tapioca flour (7%), mashed potato (8%), canola oil (6%), guar gum (2%), baking powder (1.5%) and salt (0.5%). Fresh vegetables (carrots, broccoli, spinach, and red onion) were chopped and mixed with the base formulation (1:1). Chopped fresh garlic (5%) was added to carrot, broccoli and spinach (base-vegetable mix, BFV). Snack dough was prepared using 100 mL water per 100 g BFV. Two portions of snack dough (about 10 g each) were placed on the preheated KrumKake Baker and cooked for 2 minutes. Sixty two in-house volunteers judged Broccoli-Garlic snacks as significantly (p ? 0.05) better in color/appearance than Carrot-Garlic, Spinach-Garlic and Red Onion savory snacks. A 30 g serving of these low salt, low fat healthy snacks would provide 5-7% of daily recommended dose of dietary fiber and potassium. This is the first report of developed whole grain gluten-free, 50% vegetable snacks. Texture and water activity of the developed snacks suggests the crispiness and potential long shelf stability. Tasters judged Carrot-Garlic (88%), Broccoli-Garlic (77%), Spinach-Garlic (68%) and Red Onion (65%) acceptable. Data suggest that the acceptability of gluten-free whole grain vegetable savory snacks is very encouraging and offers healthy alternative for all and especially for those sensitive to gluten.</p>

The Individual

The effects of ball milling treatment on both the structure and properties of guar gum (GG), tara gum (TG), and methylcellulose (MC) were analyzed prior to assessing their potential interactions with starch components when they are used alone or in blends in a corn starch–rice flour system. X-ray diffraction profiles showed that the ball milling caused a reduction in the crystallin domain and, in turn, a diminished viscosity of the GG aqueous solutions. Despite an increase in its viscosity properties, effects on TG were minimal, while the milled MC exhibited reduced crystallinity, but similar viscosity. When both milled and un-milled hydrocolloids were individually added to the starch–flour system, the pasting properties of the resulting mixtures seemed to be affected by the type of hydrocolloid added rather than the structural changes induced by the treatment. All hydrocolloids increased the peak viscosity of the binary blends (especially pure GG), but only milled and un-milled MC showed values of setback and final viscosity similar to those of the individual starch. Ball milling seemed to be more effective when two combined hydrocolloids (milled GG and MC) were simultaneously used. No significant differences were observed in the viscoelastic properties of the blends, except for un-milled GG/starch, milled TG/starch, and milled MC/milled TG/starch gels.

The article highlights the relevance of the development of flour products of Georgian cuisine using gluten-free flour. The technology of gluten – free khachapuri with cheese with the use of gluten – free types of flour – corn, rice and structurants – corn starch and a complex of polysaccharides of flax is substantiated. Traditional khachapuri technology involves the use of wheat flour, which cannot be used in the production of gluten products due to the presence of gluten in gluten proteins. However, according to previous research, other types of gluten-free flour can be effectively used in the production of gluten-free products – corn, rice in combination with effective structuring agents – starch, non-starch polysaccharides. In this regard, we proposed in the production of yeast dough for khachapuri to use a flour mixture of corn and rice flour in combination with corn starch and flaxseed flour, which is characterized by a complex of polysaccharides – cellulose, insoluble polymers of phenolic slime, lime. The share of dietary fiber is up to 28% by weight of flax seeds or non-fat flaxseed flour. Dietary fiber helps to stimulate the intestines in constipation, play a positive role in reducing the risk of coronary heart disease, preventing bowel cancer, reducing obesity. Flaxseed mucus has a well-defined ability to swell, and therefore show high viscosity in aqueous solution or suspension. The hydrocolloid nature of the mucus has a beneficial effect on the water-binding and emulsifying properties of flaxseed flour. The developed products are characterized by high quality and competitiveness, they can be offered for health nutrition of various segments of the population, and nutrition of patients with gluten enteropathy. Due to the high content of dietary fiber, in particular valuable for the prevention of cardiovascular disease, obesity and colon cancer soluble fiber flax flour, it can be recommended for the health of people I work in toxic industries and live in environmentally polluted areas.

In this study, we evaluated the effect of enrichment of bread using acerola fruit powder on the physical, sensorial and antioxidant properties of gluten-free breads. We tested different proportions of acerola fruit powder (0–5% w/w) in rice flour. According to the results, loaf volume increased from 423.33 cm3 to 571.67 cm with increasing amount of acerola fruit powder cm3 with increasing amount of acerola fruit powder (from 0 to 5% w/w). Acerola fruit powder improved the structural parameters of the crumb by increasing the size and area fraction of cells. All tested quantities of acerola fruit powder improved textural parameters by decreasing firmness and chewiness and by increasing springiness. In addition, acerola fruit powder positively affected the antioxidant properties of enriched breads. The total phenolic content and antioxidant activity of extracts was found to be increased with the addition of acerola fruit powder. All antioxidant activities were found to be increased with increasing quantities of acerola fruit powder. The sensory attributes of the bread showed that a partial replacement of the rice flour with up to 3% of acerola fruit powder provided satisfactory results. The optimum level of acerola fruit powder for all parameters tested was found to be 3% w/w.

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.

Background. Gluten-free types of flour (corn, rice) with the absence of gluten proteins, show special abilities for moisture absorption, which differ from those that are characteristic for wheat flour. Researches in this direction are fragmentary. Consequently, the aim of the article is to study the influence of granulometric characteristics on the moisture-absorbing capacity (MAC) and to determine methods for increasing the technological potential of gluten-free flour raw materials. Materials and methods. The corn flour and rice flour were used. Micropho­to­graphs were taken with the CL PC camera 4.5 digital microscope. The determination of gra­nulometric composition of flour was carried out by the average mass diameter method using Cooling Tech 4.5 software. The moisture absorption capacity of flour was deter­mi­ned by a Brabender farinograph, Germany. Result. The particle size of rice flour is determined by the "dark-field" method and corn flour by the "light-field" method. The obtained results show that rice flour is characterized by a relative uniformity in particle size and a high degree of dispersion, and as a result, has a good moisture-absorbing capacity (78.4 %). In corn flour, particles with average diameters from 100 to 250 microns (68.3 %) have the highest specific weight, the content of relatively large particles (more than 300 microns) is 11.2 %, and in the total area of particles 26.9 ± 4.2 %, which negatively affects the moisture-absorbing capa­city of flour and the consumer properties of ready-made cupcakes. To ensure the uniformity of particle sizes of the dispersed phase (a mixture of corn and rice flour) in the developed technology of gluten-free cupcakes, it is proposed to use a method of re-grin­ding, the feasibility of which is confirmed by the results of a study of the dispersed distribution of corn flour particles after re-grinding. Conclusion. It is proved that one of the factors that significantly affect the mois­ture-absorbing capacity of gluten-free flour, the speed of dough formation, consistency, and consumer properties of ready-made gluten-free cupcakes is the granulometric com­position of flour. The method of re-grinding corn flour is proposed in the development of gluten-free cupcake technology to ensure the uniformity of particle sizes of a mixture of corn and rice flour.

AbstractThe study aimed to determine the effect of pea protein powder on the pasting behavior and physico-chemical properties including the composition of amino and fatty acids of gluten-free bread with low-carbohydrate content. The control bread recipe was based on buckwheat flour (50 g) and flaxseed flour (50 g) as main flours. Additionally, the improving additives for this control bread such as psyllium husk (4 g), potato fiber (2 g), and guar gum (2 g) were used. The mixture of base flour was supplemented with the addition of pea protein powder (PPP) in the amount ranging from 5 to 25%. The results of Visco analyzes measured by RVA apparatus showed that the addition of 10% PPP to the control bread did not significantly differentiate peak viscosity and pasting temperature which was at the level 3115 cP and 3149 cP and 50 °C, respectively. Supplementation of low-carbohydrate bread with 10% of PPP was acceptable and significantly increased the content of all analyzed amino acids, as well as the amount of α-linolenic acid concerning the control bread. The lowest value of chemical score was observed for leucine. The EAAI (essential amino acid index) value increased from 34 to 40 when the optimal protein supplement was added. The developed gluten-free, low-carbohydrate, and high protein bread was characterized by contents of carbohydrate of 16.9%, protein of 17.1%, fiber of 13.7%, fat of 3.3% and its calorific value was 194 kcal/100 g.
