Recycling of by-products from the food industry has become a central part of research to help create a more sustainable future. Brewers’ spent grain is one of the main side-streams of the brewing industry, rich in protein and fibre. Its inclusion in bread, however, has been challenging and requires additional processing. Fermentation represents a promising tool to elevate ingredient functionality and improve bread quality. Wheat bread was fortified with spray-dried brewers’ spent grain (BSG) and fermented brewers’ spent grain (FBSG) at two addition levels to achieve “source of fibre” and “high in fibre” claims according to EU regulations. The impact of BSG and FBSG on bread dough, final bread quality and nutritional value was investigated and compared to baker’s flour (BF) and wholemeal flour (WMF) breads. The inclusion of BSG and FBSG resulted in a stronger and faster gluten development; reduced starch pasting capacity; and increased dough resistance/stiffness. However, fermentation improved bread characteristics resulting in increased specific volume, reduced crumb hardness and restricted microbial growth rate over time. Additionally, the inclusion of FBSG slowed the release in reducing sugars over time during in vitro starch digestion. Thus, fermentation of BSG can ameliorate bread techno-functional properties and improve nutritional quality of breads.

The basic information about the functional properties of combined minced fish meat developed on the basis of a combination of animal and vegetable products in a specialized product is presented. This mutual addition of the recipe with various components allows creating a model functional minced meat and products based on it that best meet the needs of the body in terms of nutritional and biological value. Food products that have functional properties are timely, and their development is relevant. The purpose of the research was to develop technologies and recipes for minced fish products with dietary supplements. The objects of the research in the development of the recipe and technology of model minced fish meat were: pollock, cod, wheat bread made from premium flour, dried mushroom oil extract, juniper oil extract, coriander oil extract and "Moby Lux Universal" as a dietary supplement. Oil extracts of vegetable raw materials were used as plasticizing additives and flavoring agents. The use of additives of plant origin allows stabilizing the functional and technological properties of raw materials, increase the biological value, and emphasize the organoleptic characteristics of the finished product.

The aim of this work was to investigate the effect of date seed water-soluble polysaccharides (DSP) and hemicellulose (DSH) as dietary fiber sources in enhancing the wheat bread’s quality. DSP and DSH were extracted from the three date seed varieties Deglet Nour, Ghars Souf, and Allig. The extraction yields ranged from 3.8% to 6.14% and from 13.29% to 18.8%, for DSP and DSH, respectively. DSP and DSH showed interesting functional properties and were incorporated at 0.5% and 0.75% (w/w) in wheat flour with low bread-making quality (FLBM). The results showed that the addition of 0.75% DSH significantly improved the alveograph profile of the dough, and in a more efficient way than that of DSP. Furthermore, bread evaluation revealed that the addition of DSH considerably improved the volume (by 24.22%) and the texture profile of bread (decrease of the hardness and chewiness by 41.54% and 33.81%, respectively), compared to control bread (prepared with FLBM). A sensory analysis showed that the better overall acceptability was found for bread supplemented with DSH. Results in this work demonstrate that hemicellulose fraction extracted from date seeds (DSH) and added with a level of 0.75% to FLBM represents the component that improved bread quality the best.

The present study was undertaken to develop bread from composite flours. Composite flours were prepared by blending wheat flour with watermelon rind flour in ratios of 100:0 (AB1), 90:10 (AB2), 80:20 (AB3), 70:30 (AB4) and 60:40 (AB5), respectively. This study was carried out to ascertain the effects of watermelon rind flour at different replacement levels (0%, 10%, 20%, 30%, 40%) on the proximate and functional properties of composite wheat bread. The results of proximate properties determination on wheat/flour blend gave low bulk densities of 0.54g/cm3 to 0.60g/cm3, high water absorption capacity of 2.389 to 3.044 g/g as well as a high swelling capacity of 5.764 to 7.610 g/g and a low oil absorption capacity of 1.608 to 2.150 g/g. The results of proximate composition of composite bread revealed an increase in % protein, % carbohydrate and % ash from 15.7% to 18.8%, 47.1% to 52.0% and 0.6% to 1.2% respectively and a subsequent decrease in % fat from 18.4% to 13.8. There was a reduction in energy density for composite bread. The functional properties of composite flours such as swelling capacity, water absorption capacity, oil absorption capacity and bulk density were increased with increase in the incorporation of watermelon rind flour with wheat flour. Thus, the results indicate that by incorporating watermelon rind flour, it is possible to enhance the nutritional quality, chemical and functional properties of bread.

The basic information about the functional properties of combined fish minced meat, developed on the basis of a combination of animal and vegetable products in a specialized product. Food products with functional properties are timely, and their development is relevant. The purpose of research is the development of technology and formulations of minced fish products with dietary supplements. The objects of study in the development of the recipe and technology of model minced fish were: pollock, cod; wheat bread from premium flour, oil extract of dried mushrooms, juniper oil extract, coriander oil extract and Moby Lux Universal as a dietary supplement. As a plasticizing additive and flavoring substances used oil extracts of plant materials. The use of additives of plant origin allows you to stabilize the functional and technological properties of raw materials, increase biological value, emphasize the organoleptic characteristics of the finished product. Oil extracts of plant materials and Mobi-Lux Universal are rich in minerals and vitamins, dietary fiber, protein, polyunsaturated fatty acids. The rare chemical composition of the presented additives helps to improve the taste and increase the nutritional and biological value of combined fish culinary products. We used standard and generally accepted sensory, rheological, physicochemical and microbiological methods for studying raw materials, semi-finished products, and finished products. Mathematical processing of the research results was carried out using the Curve Expert Ver software package. 1.34. New taste qualities of fish steam cutlets have been developed, both with the addition of dietary supplements, such as dried mushroom extract, coriander extract and Moby Lux Universal, and without addition (control). It was found that even with short-term storage in all samples and control, the pH of the medium decreases in the range 1.31 – 1.36%. The obtained water-holding ability (WCS) of fish minced meat is in the range: for cutlets 74.3–77.2%; steaks 75.4 – 79.3%; raw minced meat – 72.2%. The most adjusted amino acid composition of steam cutlets with Moby-Lux Universal. Unconventional gamma obtained in cutlets and steaks with extract of dried mushrooms, coriander extract.
