The aim of the study was to compare the carcass and meat quality of geese fed with soybean meal or yellow lupin. In total, 210 White Kołuda® geese were divided into 2 groups (1, soybean meal (SBM); 2, yellow lupin (YL), potato protein, and brewer’s yeast) of 5 replications (21 birds per each). After 16 weeks, 10 geese (5 females, 5 males) from each group were slaughtered. Carcass dissection was done, and major physicochemical traits were analysed (pH, water holding capacity, drip loss, color, and chemical composition of muscles). Weight of leg muscles and their proportion in the carcass were higher (p < 0.05) in SBM. Breast muscles from SBM were characterized by increased (p < 0.05) drip loss, enhanced (p < 0.05) content of protein, water, collagen and connective tissue, and lower (p < 0.05) fat content. Leg muscles from SBM were characterized by higher (p < 0.05) protein and water content but decreased (p < 0.05) salt and fat content compared to YL. The addition of YL (approx. 28%), potato protein, and brewer’s yeast had no negative effect on most meat traits and could partly replace SBM as a protein source in geese feeding. Hence, yellow lupin, potato protein and brewer’s yeast can be used in geese rearing followed by fattening with oats. Some producers do not have the option of using soybean meal. Small-scale farms use their own crop resources, so lupins can be an alternative source of protein for soybean meal.

The aim of the study was to analyze the quality of geese meat receiving feed with soybean meal (group 1), yellow lupin (group 2), narrow-leaved lupin (group 3), or white lupin (group 4). In total, 400 male White Kołuda® geese were randomly assigned to four groups, with 10 replicates and 10 birds each, during the 77-day rearing period. After the end of the rearing period, 10 birds from each group were slaughtered and dissected. Meat quality traits were measured. Based on the production results, it can be concluded that geese use fodder with yellow and white lupin to the same degree as in the case of the control group and higher body weight gain was recorded in the first rearing period. In contrast, the use of narrow-leaved lupin in mixtures for geese worsened the feed used. Meat traits were similar in all groups, including the content of muscles and fat in the carcass (p > 0.05), excluding abdominal fat. The weight of abdominal fat and its proportion in the carcass were higher (p < 0.05) in geese from group 4. A higher (p < 0.05) pH was found in group 1. The protein and intramuscular fat content in breast muscles was highest (p < 0.05) in geese from group 4, and a higher water content was found in group 1. The protein content in leg muscles was higher in group 3, and the fat content was higher in group 4 (p < 0.05). The color and water-holding capacity of meat were comparable in all groups (p > 0.05). The analysis revealed a positive effect of replacing soybean meal with alternative protein sources, especially yellow and white lupin, on the growth performance and quality of goose meat.

β-glucan extraction from spent brewer’s yeast is a long process that starts with the lysis of yeast cells, this step lasting up to 36 h and can be disadvantageous when working on a small scale. In this study, a rapid cell rupture method was selected for the lysis of spent brewer’s yeast to obtain β-glucans. Optimal parameters were determined for the lysis of a cellular suspension of spent brewer’s yeast by vortexing with glass beads. Thus, parameters such as the number of 10 min vortex cycles from 1 to 3, the concentration of cell suspension (5, 10, and 15%), and the ratio of yeast/glass beads (1:1, 1:2, and 1:3) were varied in a Box-Behnken design. A cell lysis mechanism using glass beads allows the cell to rupture and permits the removal of intracellular content. An increase in yeast suspension concentration decreased the disruption efficiency, while a proportional increase was observed with the yeast/glass beads ratio and the increasing number of vortexing cycles. The optimal parameters for cell lysis were found to be a cell suspension concentration of 5%, a ratio of yeast/glass beads of 1:2, and a vortexing cycle of 3, with a disruption efficiency of 99.8%. The β-glucan fraction extracted from the optimal sample showed characteristic absorption bands at 1370.77 and 1153.92 cm−1, the content of β-glucan being 78.53%.

Разработка безотходных и малоотходных технологий - одна из важнейших задач развития пищевой промышленности. Апсайклинг (англ. upcycling) - вторичное использование чего-либо для создания новых продуктов с целью снижения отходов. Зерновая дробина - ценное сырье для производства мучных кулинарных изделий, так как в своем составе содержит пищевые волокна. Отработанные пивные дрожжи представляют собой высококачественный пищевой продукт, компоненты которого благоприятно воздействуют на пищеварение. Апсайклинг пивной дробины как сырьевого компонента позволяет получить в том числе и хлебобулочные изделия, которые по органолептическим и физико-химическим показателям не отличаются от изделий, изготовленных по традиционной рецептуре. Апсайклинг пивных дрожжей целесообразен при производстве мучных кулинарных изделий, благодаря насыщенному химическому составу, может применяться в качестве обогащения изделий, при приготовлении по традиционным рецептурам. В данном исследовании было изучено влияние добавок пивной дробины и остаточных пивных дрожжей на качество хлеба. Применение остаточных пивных дрожжей и пивной дробины обеспечивает выработку хлеба высокого качества и, вероятно, способствует дополнительному обогащению мучных кулинарных изделий белками, пищевыми волокнами, микроэлементами, витаминами. Рассматриваемая тема по использованию апсайклинга пивоваренных ресурсов актуальна для предприятий общественного питания, имеющих пивоварни в плане выработки продукции, которую можно отнести к группе с функциональными характеристиками, так как пивная дробина и остаточные пивные дрожжи - это источник естественных нутриентов. Апсайклинг в пищевой промышленности - это актуальный и современный технологический прием, позволяющий решить множество проблем, а в первую очередь внести пользу в рацион питания, без изменения привычных органолептических характеристик кулинарных изделий. One of the most important tasks in the development of the food industry is the development of waste-free and low-waste technologies. Upcycling is the reuse of something to create new products in order to reduce waste. Grain grain is a valuable raw material for the production of flour culinary products, as it contains dietary fiber. Waste brewer's yeast is a high-quality food product, the components of which are beneficially involved in digestion. Upcycling of brewer's grains as a raw material component allows obtaining, among other things, bakery products, which, in terms of organoleptic and physicochemical indicators, do not differ from products made according to traditional recipes. Upcycling of brewer's yeast in the production of flour culinary products is expedient due to its rich chemical composition, which can be used as product enrichment when cooking according to traditional recipes. In this study, the effect of the addition of brewer's grains and residual brewer's yeast on the quality of bread was examined. The use of residual brewer's yeast and brewer's grains ensures the production of high-quality bread and probably contributes to the additional enrichment of flour culinary products with proteins, dietary fibers, microelements, vitamins. The topic under consideration on the use of upcycling of brewing resources is relevant for public catering enterprises that have breweries in terms of product development, which can be attributed to a group with functional characteristics, since brewer's grains and residual brewer's yeast are a source of natural nutrients. Upcycling in the food industry is a relevant and modern technological method that allows you to solve many problems, and, first of all, bring benefits to the diet, without changing the usual organoleptic characteristics of culinary products.

The mass production of mosquitoes is becoming more wide-spread due to the increased application of the sterile insect technique (SIT) and other genetic control programmes. Due to the variable availability and high cost of the bovine liver powder (BLP) constituent of many current larval diets, there is an urgent demand for new ingredients in order to support sustainable and efficient mosquito production while reducing rearing cost, without affecting the quality of the insects produced. Two black soldier fly (BSF) powder-based diet formulations (50% tuna meal, 35% BSF powder, 15% brewer’s yeast and 50% tuna meal + 50% BSF powder) were tested for their suitability to support the development of Aedes aegypti and Ae. albopictus mosquitoes in mass-rearing conditions. Overall, the results indicate that the use of the BSF powder did not negatively impact the development and quality of the produced insects in terms of time to pupation, adult production and male flight ability. Furthermore, depending on the species and diet formulations, there were improvements in some parameters such as female body size, egg production, egg hatch rate and male longevity. BSF powder is a valuable ingredient that can effectively replace costly BLP for the mass production of high quality Ae. aegypti and Ae. albopictus mosquitoes. Both diet formulations can be used for Ae. aegypti showing high plasticity to nutrition sources. However, for Ae. albopictus we recommend the combination including brewer’s yeast.

Following disparity of earlier results, this study tested the performance of African catfishClarias gariepinusfed dried brewer’s yeast slurry meal (DBYM) based diets. Fingerlings ofC. gariepinuswith pooled mean initial weight of1.58±0.01 g were stocked in hapas (1 m × 1 m × 1 m) immersed in an earthen pond at a density of 15 fish per cage. Five diets with increasing substitution of soybean meal with 25%, 50%, 75%, and 100% of dried brewer’s yeast and a control without dried brewer’s yeast (0% substitution) were evaluated for 8 weeks. Palatability of diets reduced with increasing levels of DBYM. Growth and utilization parameters such as weight gain, feed conversion ratio, protein efficiency ratio, and specific growth rate differed significantly (p<0.05) among treated groups. Specific growth rate decreased with increasing substitution while the best feed conversion ratio was obtained in the diet devoid of DBYM. Protein efficiency and utilization decreased with increasing levels of DBYM. Body composition was also affected by inclusion of DBYM with significant differences (p<0.05) being observed across the diets. The trend in body composition follows the utilization of the diets. We conclude that the optimal range of inclusion and substitution of soybean meal with DBYM inC. gariepinusfeed is between 1% and 14% of dry matter.

The waste brewer's yeast S. cerevisiae (activated and non-activated) was compared with the commercial baker's yeast regarding the volume of developed gas in dough, volume and freshness stability of produced bread. The activation of waste brewer's yeast resulted in the increased volume of developed gas in dough by 100% compared to non-activated brewer's yeast, and the obtained bread is of more stable freshness compared to bread produced with baker's yeast. The activation of BY affects positively the quality of produced bread regarding bread volume. The volume of developed gas in dough prepared with the use of non-activated BY was not sufficient, therefore, it should not be used as fermentation agent, but only as an additive in bread production process for bread freshness preservation. Intense mixing of dough results in more compressible crumb 48 hrs after baking compared to high-speed mixing.
