Summary This study investigated the application of hydroxypropylmethylcellulose (HPMC) (2%, 3%, 4%), sugar beet fibre (SBF) (3%, 5%, 7%) and water (210%, 220%, 230%) into maize‐based gluten‐free (GF) formulations and their effects on the GF batter rheology and bread quality. HPMC incorporation in higher amounts reduced the compliance values of GF batter samples and increased the values of dynamic moduli indicating an improvement in the GF batter elastic characteristic. The same course of action with a less pronounced influence on mentioned rheological parameters had SBF addition. GF bread quality evaluation in terms of specific loaf volume and crumb texture (hardness, cohesiveness and springiness) reveals that HPMC and SBF incorporation at higher levels enhanced these quality parameters. The inclusion of HPMC and SBF coupled with adequate water content can improve the nutritional value of GF bread without negative influence on bread quality.

Biopolymer-based stabilizers are becoming particularly favourable natural solutions for application in complex systems, such as O/W emulsions. Individual and combined impact of three polysaccharide-based stabilizers (sugar beet fibers, sugar beet pectin and OSA modified maltodextrin) on the formation and stability of corn oilin-water emulsions was evaluated. The obtained emulsion droplet mean diameters ranged from 4.9 to 10.1 μm, indicating good emulsifying properties of the stabilizers used. The application of sugar beet fibers (SBF) resulted in emulsions with lower creaming index values compared to the sugar beet pectin (SBP) and OSA modified maltodextrin (OSAm) emulsions, hence it significantly affected emulsion stability. The interactions between applied polysaccharide-based stabilizers resulted in significant changes regarding emulsion creaming, zeta potential, droplet size and droplets' size distribution. Overall, OSAm-SBF combined impact is expressed through the production of emulsions having the most prominent overall characteristics in terms of surface weighted mean diameter, specific surface area and creaming index values. The OSAm and SBP combined influence on emulsion properties is characterized by relatively low values of droplet mean diameters and high level of droplet size uniformity. The possible competition in the process of adsorption on droplet surface is noticed in the experiments where combined SBF and SBP were used.

The influence of the physicochemical properties of chestnut flour (CF) on the cookies quality was investigated. The experiments are planned on the base of 32 factorial plan with independent variables: chestnut flour quantity (20, 40 and 60% based on wheat flour) and moisture dough (20, 22 and 24%). The physical and sensory attributes of CF cookies were compared to control sample containing 100% wheat flour (WF). Substitution of WF with CF contributes to the increased cookies hardness for 10–40%. By increasing the dough moisture, the hardness of cookies containing 60% CF is reduced by 20–30%. Formulations with 20 and 40% CF and 24% dough moisture had the best sensory properties and improved nutritional quality. By increasing the share of CF, the red tone increases (a* parameter) and the color lightness of cookies reduces (parameter L*). In conclusion, the application of CF in cookie formulations can improve sensory and nutritional quality of cookies. Practical Applications Tea cookies are widely consumed as confectionary products, which are traditionally made from wheat flour. Several studies demonstrated that chestnut flour contains nutrients that have many health‐care functions. In this regard, it would be beneficial to develop a novel formulation for cookies with chestnut. This study explores the possibility of utilizing chestnut flour, at different substitution levels in order to produce cookies with acceptable sensory properties for consumers.

The influence of the low-trans (<1% of total fatty acids) puff pastry margarine and the rest period between laminating on dough physical characteristics and puff pastry quality was investigated. Experiment was planed according to factorial plan 3 2 with independent variables: quantity of puff pastry margarine (35-55% based on flour, variation interval 10) and rest period (15-45 min, variation interval 15). The experiment involved two margarine samples (MLT1 and MLT2) of similar fat phase composition, but whose physical properties were, statistically speaking, significantly different. The results show that the pastry containing 35% of margarine MLT1 and allowing the rest period of 30 and 45 min has a lift of above 4.0, it is of minimal firmness and has a high specific volume (3.5 cm 3 g )1 ). Having used puff pastry margarine MLT2, the highest quality of dough and pastry was achieved in the sample containing 55% of margarine and with the maximum rest period of 45 min. The sample mentioned showed an excellent lift of 5.3 and had a specific volume of 4.0 cm 3 g )1 , but it as well exhibited the maximal firmness of pastry. The application of puff pastry margarine MLT1 can result in a satisfactory quality of pastry, but it can also cause a reduction in the fat content by 7.5% and in the content of trans fatty acids by two times, while the energy value is reduced by 12% when compared with the pastry containing puff pastry margarine MLT2.
