The aim of this study was to analyse the effect ferrous gluconate and ferrous lactate on the rheological be- haviour of dough from a high extraction rate. For fortification of wheat flour, we used iron ions in a divalent form in amounts of 3, 4, and 5 mg/100 g. To record the rheological characteriscics of the fortified wheat flour dough, Farino- graph, Amilograph, Falling Number, Rheofermentometer, and Thermo Haake Mars dynamic rheometer were applied. The Farinograph did not show significant changes in the water absortion values in the samples with ferrous salts. As for dough development time and dough stability, small amounts of ferrous additives increased and large amounts de- creased those parameters. The effect was more significant in the samples with ions from gluconate form than from lactate salt. The Amylograph recorded an increased peak viscosity with an increasing ferrous salt quantity. That was the case for both ferrous salt forms. The increased was in a similar way for both types of ferrous salt forms used. The total CO volume production and the retention coefficient obtained with the help of the Rheofermentometer device increased in the dough samples with 3 and 4 mg of iron/100 g. However, the addition of 5 mg of iron decreased those indicarors. The decrease was more significant for iron ions from ferrous ferrous gluconate than from ferrous lactate. The fundamental rheological properties of the dough were analysed by using a frequency sweep and oscillatory tem- perature sweep test. Ferrous lactate and ferrous gluconate influenced both the fundamental and empirical rheological properrties og the dough in similar way.

In this work, the quality and rheological parameters such as moisture, ash, color, falling number, gluten, and alveographic indexes (W, P/L, and I/E) were determined in wheat flour samples provided from the industrial process through digital images and multivariate calibration, based on partial least squares (PLS) regression. The models were validated by the evaluation of the figures of merit such as accuracy, the inverse of analytical sensitivity, adjust, linearity, relative prediction deviation, limits of detection, and quantification, indicating that the proposal is feasible and can be used in the industrial routine analysis as an alternative to the methods highly dependent on the analyst perception, and extremally time-consuming.

The influence of the addition of partially defatted milk thistle seed flour was studied by analyzing the rheological properties of dough in order to further exploit the functionality of partially defatted milk thistle flour in bakery products. The rheological properties of dough were monitored using Mixolab 2 (Chopin Technologies, France). A rheofermentometer F4 (Chopin Technologies, France) was used to check the dough fermentation, and for the baking trials wheat flour, rye flour, and milk thistle flour were kept in the portion: 50:50:0 (control flour); 50:45:5; 50:40:10 and 50:35:15. The addition of different milk thistle flour in the mixtures resulted in a difference in the viscoelastic properties of the dough. The results showed a weakening of the gluten network in all trial mixtures evaluated. The dough development time values of the control flour were 1.20 min, while an addition of milk thistle flour in portions of 5, 10, and 15% increased these values to 1.30 min, 1.90 min, and 2,80 min, respectively. In addition to higher dough development time values, all trial mixtures exhibited also higher stability (5.07 min; 6.25 min and 8.03 min), when compared to the control flour (4.63 min). The trial mixture with 15% milk thistle flour had different characteristics of gelatinization and retrogradation. The rheofermentometer measured the dough characteristics during proofing, and the trial mixtures with the addition of MTF had a retention volume at approximately the same level as the control flour (WRF). The Volscan profiler was used to determine the bread volume and other parameters. All breads had high volume and specific volume values and can be rated as good, with good porosity and ratio. Mixtures containing 5%, 10% and 15% milk thistle flour added to wheat flour + rye flour maintained rheological parameters within the recommended limits for good technological behavior and, consequently, good quality of bakery products. From all of the above data, it can be stated that, with regard to their baking characteristics, these flour mixtures fall into the category of flours suitable for bakery products.

The effects of wheat flour substitution by sweet potato powder on rheological parameters of wheat dough and physical parameters of cookies and crackers were analyzed. Wheat flour was substituted with sweet potato powder at level 2.5%, 5%, 7.5%, and 10%. Sweet potato powder was characterized by high water holding capacity (9.00 g/g) and swelling capacity (8.16 cm3/g). The addition of sweet potato powder significantly changed the rheological properties of wheat dough (water absorption and mixing tolerance index were increased, dough stability was reduced, and dough development time was prolonged). It was also found that volumes of cookies and crackers were decreased, and spread ratios were increased with the addition of sweet potato powder. Lightness of baked products decreased and yellowness increased with the addition of sweet potato powder. Incorporation of sweet potato powder significantly decreased the hardness of cookies and crackers. Sensory evaluation showed that the most acceptable cookies and crackers were the ones obtained after the addition of sweet potato powder at level 2.5% and 7.5%, respectively.

The aim of this study was to assess the influence of the magnesium ions from lactate salt at the level of 100, 150 and 200 mg/100g addition on the rheological properties of the wheat flour dough of 550 type. For this purpose, the empirical dough rheological properties were investigated during mixing, pasting and fermentation process by using the Farinograph, Falling Number, Amylograph and Rheofermentometer devices. During mixing dough hydration capacity decreases with the increased level of magnesium ions addition whereas the dough stability and dough development time decreases at low levels of magnesium ions addition and increases at high levels. The temperature at peak viscosity, total CO2 volume production and the total volume of CO2 lost decreases with the increased level of magnesium addition. PCA analysis shows that the wheat flour with 100 mg and 150 mg /100g magnesium ions addition presents a similar behaviour slightly different to those with 200 mg /100g magnesium ions addition (P < 0.05).

Представлены результаты исследования влияния компонентов мучной композитной смеси – муки люпиновой, кукурузной и ячменной на автолитическую активность и углеводно-амилазный комплекс пшеничной муки 1-го сорта. Для определения автолитической активности по числу падения (ЧП) образцов муки с добавками и без них добавки вносили в количестве 5, 15, 25, 35%. Установлено, что при внесении 5% ячменной и кукурузной муки автолитическая активность существенно не меняется, при увеличении количества добавки показатель ЧП муки увеличивается от 3 до 14% и автолитическая активность снижается. Величины показателей газообразующей и водопоглотительной способности мучных композитных смесей возрастают по сравнению с аналогичными показателями контрольного образца – пшеничной мукой 1-го сорта без добавок. Рекомендовано использовать разработанную мучную композитную смесь, содержащую 65% пшеничной муки, 25% люпиновой муки, 5% кукурузной муки, 5% ячменной муки, при производстве пшеничных сортов хлеба для улучшения реологических свойств теста и, следовательно, качества хлеба. Results of investigation of influence of components of flour composite mixtures – lupine, cornmeal and barley flour on autolytic activity and carbohydrate-amylase complex of wheat flour of 1st grade are presented. To determine the autolytic activity by of falling number (FN) flour samples with additives and without them additives were brought in the amount of 5, 15, 25, 35%. It is established that with the introduction of 5% barley flour and cornmeal autolytic activity does not change significantly, with an increase in the number of additives, the index of FN flour increases from 3 to 14% and autolytic activity decreases. Values of indicators of gas-forming and water-absorbing ability of flour composite mixtures increase in comparison with similar indicators of a control sample – wheat flour of 1st grade without additives. It is recommended to use the developed flour composite mixture containing 65% wheat flour, 25% lupine flour, 5% cornmeal, 5% barley flour in the production of wheat breads to improve the rheological properties of the dough and, therefore, the quality of bread.

The effects of amaranth and quinoa flours and protein isolates prepared from amaranth and quinoa seeds on the rheological properties of wheat flour dough and bread were studied using new recording instruments, the micro Z-arm mixer (for dough) and the SMS-Texture analyser (for bread crumb). The addition of 10% amaranth or quinoa flours did not cause significant changes in rheological properties. However, higher additions (20% and 30%) resulted in significant changes in stability, the degree of softening and elasticity. Substitution of wheat flour by amaranth or quinoa flours resulted in an increase of water absorption capacity. A significant reduction of specific volume and an increase of resistance to deformation (firmness) of the crumb of breads prepared from flour mixtures containing high percentages of amaranth or quinoa flours was observed. The addition of protein isolates did not significantly influence the main rheological parameters of dough, and bread crumb.

This study has evaluated the effects of adding 4%, 6% and 8% soy fiber to wheat pasta for the production of dry wheat spaghetti. The properties of the mixture were evaluated for humidity, falling number, ashes, color, retained gluten, and subjected to farinograph (water absorption, development, stability) and extensograph analyses (resistance and extensibility). The spaghetti was evaluated with cooking tests (performance, increased volume, loss of soluble solids to cooking water) and sensory analysis. The addition of soy fiber to wheat flour resulted in mixtures with rheological and physicochemical characteristics suitable for the production of wheat spaghetti, enhancing performance and reducing the loss of soluble solids to the cooking water. The sensory analysis showed that, for all parameters tested, panelists favored mixtures with up to 6% soy fiber addition.

The effect of the incorporation of various types of residual chia flour (whole, semi-defatted and defatted, with or without mucilage) on the technological quality of bread was investigated. The various types of chia flour were used to substitute 5 and 10% wt/wt of wheat flour in the bread formulations. The water absorption, dough development time and stability of blends with the presence of mucilage and the incorporation of 10% wt/wt of chia flour demonstrated the highest values in comparison with the other ones. The specific volume of the flour variants with 5% wt/wt of chia flour with mucilage were similar to the control bread; while those formulated with chia flour without mucilage exhibited a lesser volume. The incorporation of 10% wt/wt of chia flour in the formulations caused a decrease in the technological quality of the bread as expected. The bread crust and crumb colour parameters were mainly influenced by the level of chia flour substitution, which resulted in a decrease in lightness and h values. The substitution of wheat flour with 5% wt/wt of chia flour counterparts with mucilage improved the technological quality of the breads. The different oil content of the chia flours did not show any significant influence on overall quality or texture.

The effects of wheat flour replacement at different levels (5, 7.5, 10, and 20%) by celery root and sugar beet pulp powder on rheological parameters and quality properties of enriched pasta were studied. Sensory evaluation was also investigated. Incorporation of fibre powders increased water absorption and prolonged dough stability and dough development time. Enriched pasta had higher moisture content than control pasta. Addition of fibre powders also modified the cooking quality of pasta (cooking loss and water absorption were increased and optimal cooking time was reduced). Moreover cooked pasta with the higher addition level of celery root powder was characterised by higher intensity of vegetable taste and had pleasant flavour and colour. Sensory evaluation showed that pasta with the addition of 7.5% celery root powder was the most acceptable for assessors.
