Hydrocolloids are important ingredients controlling the quality characteristics of the final bakery products. Hydrocolloids are frequently used in gluten-free (GF) recipes, mimicking some rheological properties of gluten, improving dough properties, delaying starch retrogradation and improving bread texture, appearance and stability. Hydrocolloids addition increases viscosity and incorporation of air into the GF dough/batter. Besides their advantages for the technological properties of the GF bread, hydrocolloids addition may impact the glycemic index (GI) of the final product, thus answering the demand of people requiring products with low GI. This review deals with the application of hydrocolloids in GF bread and pasta with a focus on their effect on dough rheology, bread hardness, specific volume, staling and GI.

The effect of different salt forms and concentrations were evaluated on the rheological properties of dough made from wheat and rye flours. Our aim was to investigate that how does the sodium chloride change the properties of gluten network and therefore the structure of bakery products and what effects can be experienced when it is substituted by other organic and inorganic salts. Different rheological tests were used to monitor the effects on dough (Farinograph, Alveograph and Extensigraph tests) and on the end-product (texture analysis, sensory analysis). It was found that all the salt forms significantly influenced the rheological parameters of dough and not the sodium chloride addition had the most favourable effect in every case.

Abstract This work studies the rheological properties of aqueous solutions of acrylamide copolymers. The prevailing role of elastic properties over viscous properties in predicting the proppant suspension capacity of the resulting fracturing fluid is shown. Furthermore, the potential of the use of oscillatory rheometry for studying fracturing fluid stability is demonstrated.

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.

The role of arabinoxylans (AXs) in bread-making has gained interest due to their positive contribution to bread quality. Therefore, the effect of differently extracted (water, alkaline, or enzymatic) rye AXs on gluten-free (GF) buckwheat and millet batter rheology and bread properties was evaluated. The results showed that the addition of AXs influenced most of the batter and bread properties differently, which depended on the chemical and structural properties of the AXs. All batter systems displayed a typical weak gel behavior. Enzyme- (Pentopan Mono BG-) extracted AXs (PEAXs) were able to strengthen both millet and buckwheat batter structures to a greater degree, as seen by the increase in storage modulus. Regarding bread properties, in buckwheat breads, calcium hydroxide-extracted AX (CEAX) was able to improve the specific volume (from 1.73 to 1.93 cm3/g) and firmness (from 10.88 to 4.69 N) the most, compared to the control. The AXs extracted successively with water and the enzyme Pentopan Mono BG (WPEAX) produced the highest loaf volume (2.39 cm3/g) and one of the lowest crumb firmness values (5.51 N) but caused larger pores and a ruptured crust. In millet breads, water-extracted AXs (WEAXs) and CEAX produced lowest crumb hardness (WEAX: 6.94 N; CEAX: 8.53 N). Specific volume was highest in breads with WEAX (2.35 cm3/g), but CEAX displayed a better pore structure. Overall, water-extracted AXs improved the GF bread properties to a higher extent than alkaline-extracted AXs. Only CEAX displayed a comparable effect in some cases, and considering the fact that alkaline extraction of AX is much more efficient (much higher yield), its application compared to other AXs could be more favorable. Overall, AXs hold great potential as baking improvers for GF bread; the extent of their improvement will be defined by their functional properties.
