The aim of this study was to investigate the effects of formulation factors, sea salt (SS), dry sourdough (SD) and fermented sugar (FS) as sodium chloride replacers in wheat flour on dough mixing, extension, pasting and fermentation rheological properties, evaluated by Farinograph, Extensograph, Amylograph and Rheofermentometer devices. With regard to mixing and extension properties, SS and FS presented a strengthening effect, whereas SD presented a weakening one. SS and FS presented a positive effect on dough stability, energy and resistance, whereas SD presented a negative one. On the Amylograph, peak viscosity increased by SS and FS addition and decreased when SD was incorporated in the dough recipe. During fermentation, dough development and gas production in the dough system increased after SS and SD addition, whereas they decreased after FS addition. Response surface methodology (RSM) was used to investigate the effect of independent variables on the rheological properties of the dough. Mathematical models between the independent variables, SS, SD and FS, and the dependent variables, represented by the rheological values of the dough, were obtained. The best formulation obtained was of 0.30 g/100 g SS, 0.50 g/100 g SD and 1.02 mL/100 g FS addition with a 0.618 desirability value, following Derringer’s desirability function approach. For this formulation, bread quality characteristics were better appreciated than for those obtained for the control sample, in which 1.5% NaCl was incorporated in wheat flour.

The paper investigates technological parameters of the quality of low-alkaloid lupin of five cultivars selected and grown in the Republic of Belarus during the years from 2007 to 2017. Prospects for the use of the obtained seeds have been studied. This study reveals great influence of cultivar and climatic conditions during growth of lupin seeds on correlation of anatomic parts in seeds as well as on their physical properties. Cultivar of lupin seeds Jan is recommended for whole grain flour and graded flour production based on its anatomic composition, uniformity and physical properties. A comparative analysis of chemical composition, quality parameters and technological properties of lupin flour has been done. The chemical composition of lupin flour, of whole grain lupin flour, in particular, has been found to be relatively low in starch, high in protein, food fibers, minerals and organic acids. As a result, whole grain lupin flour has been proved to have higher food value when compared to traditional wheat flour. This paper demonstrates the difference between lupin flour characteristics and those of wheat flour in terms of color, acidity, enzymatic activity and adsorbing properties. This study reveals the possibility of use of lupin flour in bakery products by substituting traditional types of flour with lupin flour at 10-30% levels, as well as by replacing egg products with lupin flour at 25-50% levels. The work highlights the use of lupin flour at the stages of dough kneading, dough preparation, foam and emulsion production mainly by using rapid dough making methods.Practical applicationsRecommendations have been made on the usage of lupin flour in the technological process of bakery products manufacturing, macaroni and flour confectionery products production.

Introduction. The research improved the formulation of semi-finished sponge cake by using the method of generalized desirability function. Traditional components were substituted with new advantageous rye varieties of local selection. The main advantage of the rye variety “Memory to Bambyshev” is that rye flour obtained from the whole grain of this variety has a lower trypsin inhibitor (1.7 mg/g) compared to flour from such varieties as “Saratov 6” (2.16 mg/g). Thus, the digestibility of the grain of this variety is higher by 0.26%. The rye can be used in baking to produce dietary breads, low-calorie bakery products with bran, and animal feed. Study objects and methods. Cakes and pastries make 34.5% of the total volume of flour confectionery products. The study developed a new semi-finished sponge-cake product, which can serve as the basis for cakes and pastries. However, flour confectionery products are oversaturated with carbohydrates and fats, which increases their calorie content. A set of experiments was performed to study the effect of reducing the amount of sugar in the formulation and replacing wheat flour with rye flour on the quality of semi-finished sponge-cake product. A basic formulation for sponge cake was used as control sample. The test semples varied in content of sugar and flour made from various types of rye. The technological additives included Ovalet emulsifier (1.5% to flour) and Duo baking powder (0.1% to flour). Emulsifier “OVALET SUPER” (Bakels, Sweden) is a pasty substance that consists of emulsifying agents, water, and stabilizers and acts as an improver, stabilizer, and structurizer designed for the production of semi-finished sponge cakes, rolls, muffins, and cookies. Duo baking powder is a special highly effective tool that does not contain tartaric acid. It can be used for the production of various varieties of bread and confectionery, e.g. biscuits, rolls, gingerbread, etc. The obtained dough was easy to process. The new formulation increased the volume and color of the product, as well as slowed down the process of hardening. Results and discussion. The highest value of the generalized function of desirability belonged to the sample where white wheat flour was subsituted with 30% of rye flour and the sample with 100% of rye flour with a 40% sugar reduction. According to the specific desirability indicators, the mass fraction of moisture, the mass fraction of total sugar, energy value, and foaming ability of the semifinished product were higher than those of the control sample. Conclusion. The developed formulation and technology can expand the range of functional products.

Abstract The present work focused on the application of design of experiment (DoE) principles to the development and optimization of a stability-indicating method (SIM) for the drug imidapril hydrochloride and its degradation products (DPs). The resolution of peaks for the DPs and their drug in a SIM can be influenced by many factors. The factors studied here were pH, gradient time, organic modifier, flow rate, molar concentration of the buffer, and wavelength, with the aid of a Plackett–Burman design. Results from the Plackett–Burman study conspicuously showed influence of two factors, pH and gradient time, on the analyzed response, particularly, the resolution of the closely eluting DPs (DP-5 and DP-6) and the retention time of the last peak. Optimization of the multiresponse processes was achieved through Derringer’s desirability function with the assistance of a full factorial design. Separation was achieved using a C18 Phenomenex Luna column (250 × 4.6 mm id, 5 µm particle size) at a flow rate of 0.8 mL/min at 210 nm. The optimized mobile phase composition was ammonium–acetate buffer (pH 5) in pump A and acetonitrile–methanol (in equal ratio) in pump B with a run time of 40 min using a gradient method.
