Приведен сравнительный анализ современных технологий ржано-пшеничного хлеба с использованием амарантовой муки, получаемой из продовольственного зерна амаранта. Отмечено преимущество технологии ржано-пшеничного хлеба с применением сухих заквасок с вводом подкисляющих добавок и хлебопекарных улучшителей, что позволяет сократить процесс производства хлеба в 2,5–3 раза по сравнению с традиционным способом на биологических заквасках. Дана оценка эффективности технологий ржано-пшеничного хлеба с использованием амарантовой муки в качестве улучшителя, предусматривающих применение добавки в сочетании с сухими заквасками-подкислителями, обеспечивающее продолжительность брожения теста до достижения требуемой кислотности не более (70 ± 10) мин. Исследовано влияние дозировки амарантовой муки – 0 (контроль); 2,5; 5,0; 7,5; 10,0; 12,5 и 15,0% на изменение удельного объема хлеба, см3/100 г, по сравнению с выбором вида амарантовой муки – цельносмолотая, белковая, крупяная. Установлено, что введение в рецептуру ржано-пшеничного хлеба закваски-подкислителя повышает хлебопекарные свойства ржаной муки с пониженной ферментативной активностью за счет добавления амарантовой муки (число падения 63 с) при показателе числа падения ржано-пшеничной смеси не менее 327–330 с. Приведенные способы изготовления ржано-пшеничного хлеба с использованием амарантовой муки прошли промышленную апробацию и рекомендованы к внедрению в производство. A comparative analysis of modern technologies of rye-wheat bread with the use of amaranth flour obtained from the food grain of amaranth is given. The advantage of the technology of rye-wheat bread with the use of dry starter cultures with the introduction of acidifying additives and baking improvers is noted, which makes it possible to reduce the bread production process by 2,5–3 times in comparison with the traditional method using biological starter cultures. Evaluation of the efficiency of rye-wheat bread technologies using amaranth flour as an improver, providing for the combined use of the additive with dry sourdough-acidifiers, which ensures the duration of dough fermentation until the required acidity is reached, no more than (70 ± 10) minutes, is given. Studied of the effect of the dosage of amaranth flour – 0 (control); 2,5; 5,0; 7,5; 10,0; 12,5 and 15,0% on the change in the specific volume of bread, cm3/100 g, in comparison with the choice of the type of amaranth flour – whole-ground, protein, cereal was carried out. It was found that the introduction of sourdough-acidifier into the recipe of rye-wheat bread increases the baking properties of rye flour with reduced enzymatic activity due to the addition of amaranth flour (falling-number value of 63 seconds) with an indicator of the falling-number value of rye-wheat mixture of at least 327–330 seconds. These methods of making rye-wheat bread with using amaranth flour have been industrially tested and recom- mended for introduction into production.

Background: The present investigation was carried to develop amaranth based wheat flour bread. Products were developed by using different levels of amaranth flour and wheat flour in the ratio of 0:100,5:95, 10:90 and 15:85 respectively. Methods: Physico-chemical, antioxidant activity, total phenolic content and physical properties of amaranth supplemented bread were evaluated. Results: Results revealed an increase in moisture content from31.41 -33.35%, ash content 0.95- 1.52%, protein content 12.19% -13.23%, fat content 2.21% -2.81% and crude fiber 1.13-1.74%, and decrease in nitrogen free extract, alkali water retention capacity 52.11-47.35% and 137.66-112.00% respectively. Also it was observed that amaranth flour supplemented bread showed decrease in total phenolic content, antioxidant activity and FRAP assay with increase in substitution level. Color evaluation showed increase in L* and a* value of bread crust, while as bread crumb shows decrease in b* and L* value respectively. Nutritional evaluation revealed that among the samples tested 85% wheat flour and 15% amaranth flour supplemented bread was rated best as it was also evident from nutritional analysis. Conclusion: Maximum substitution of wheat flour with amaranth flour were 10% in terms of desirable bread quality attributes. The composite breads would serve as functional food, because of its high nutritional value than whole-wheat bread.

Handwriting is a method to express and preserve thoughts by means of graphic signs. In the investigative and judicial practice, it is treated as an individual creation used for identification purposes in case of doubts over the authenticity of a written record. Nowadays, however, writing by hand is not the only way of conveying information, which results in moving away from this traditional method in favour of modern solutions. In the future, this tendency may limit the possibility to identify the author of a record on the basis of a handwritten record. Therefore, the purpose of this publication is to check whether contemporary handwritings show any signs of deterioration in the quality of handwritten records.

The aim of this work was to compare the nutritional characteristics of wheat bread with the bread produced of wheat flour supplemented with quinoa and buckwheat seeds. Bread making properties of these blends were analyzed in order to investigate their ability to make moulded bread. Quinoa (Chenopodium quinoa Will.) and buckwheat seeds were grown in the vicinity of Belgrade, Serbia. The addition of pseudocereal seeds (at levels of 30% and 40%) and a selected technological process, which included hydrothermal preparation of supplements, resulted with a valuable effect on nutritive value of breads. In comparison with the wheat bread that was used as control sample, the protein increase of 2% and the increase of crude fiber content at around 0.5% in 30% supplemented breads were registered. Furthermore, the incorporation of both seeds mixture at the level of 40%, increased the content of protein for 2.5% and fiber content for 0.4%. In regard to the starch, fat, and ash contents there were no major differences. The investigated breads were nutritionally superior to the wheat bread. Chemical composition of the selected seeds was also investigated. The results showed that the blends containing either 30% or 40% of selected seeds expressed high potential for the production of molded breads, as new baking products with enhanced nutritional composition. The applied technological procedure was modified in such way that for all blended combination of supplements it changed rheological properties of dough. Furthermore, it resulted in a good volume of breads with excellent sensory properties of aroma-odor and taste.

The bacterial community profile of cricket powder highlighted the presence of four main genera: Bacteroides spp., Parabacteroides spp., Lactococcus spp., and Enterococcus spp. The spontaneous fermentation of cricket powder allowed for the isolation and characterization of seven lactic acid bacteria strains belonging to six species: Latilactobacillus curvatus, Lactiplantibacillus plantarum, Latilactobacillus sakei, Lactococcus garvieae, Weissella confusa, and Enterococcus durans. The strains were characterized and selected according to different technological properties. L. plantarum CR L1 and L. curvatus CR L13 showed the best performance in terms of general aminopeptidase activity, acidification, and growth rate in MRS broth and in dough with cricket powder and wheat flour, as well as robustness during consecutive backslopping. Thus, they were used as starter-mixed to produce sourdough to manufacture bread fortified with 20% cricket powder. The addition of cricket powder led to a significant increase of protein (up to 94%) and lipid content, from 0.7 up to 6 g/100 g of bread. Spontaneous fermentation represents a source of microbial diversity that can be exploited in order to obtain potential starters for food with innovative ingredients. Edible insects powder can be successfully added in leavened baked goods to enhance their nutritional value.
