This study was performed to determine the possibility of using mango fruit (Mangifera indica) in brewing technology. The aim SPME-HS-GC-MS technique assess what changes occurred volatile composition beers brewed this study. Mango added beer five different forms ascertain kind preparation should be used improve aroma. Analysis components showed that without addition characterized by lowest content compounds (1787.84 µg/100 mL). increased concentration compounds, such as α-pinene, β-myrcene,...

The aim of this study was to test rye straw, bran and oat hydrolysates as substrates for growth the yeast Yarrowia lipolytica, a microorganism known have large biotechnological potential. First, after combined process acid-enzymatic hydrolysis, concentration composition fermentable monosaccharides in obtained were analyzed. Glucose main sugar, followed by xylose arabinose. Rye hydrolysate had highest sugar content—80.8 g/L. results showed that able grow on low-cost medium produce biomass...

Summary This study was aimed at comparing selected properties of starch citrate obtained from native or retrogrades potato various temperatures (100, 130 160 °C) and doses reactant (10, 20 40 g per 100 g). Higher susceptibility to esterification demonstrated for retrograded starch, whereas the degree produced esters varied considerably (1.4 10.0 preparation) increasing along with roasting temperature dose citric acid. The process pasting occurred only in a °C, which resulted significant...

Bread residues represent a significant fraction of retail food wastes, becoming severe environmental challenge and an economic loss for the sector. They are, however, attractive resource bioconversion into value-added products. In this study, edible filamentous fungi Neurospora intermedia Aspergillus oryzae were employed production bioethanol high-protein biomass by cultivation on enzymatically liquefied bread-waste medium at 150 g/L solids. The fermentation hydrolysate N. resulted in...

The aims of the present research include (1) optimization extraction from Vaccinium myrtillus leaf waste via investigation plant material:medium ratio, medium, and period, employing extractions at room high temperatures, or using ultrasound microwaves (M, HAE, UAE, MAE, respectively), (2) physicochemical characterization, (3) extract biological potential. statistical analysis revealed that optimal levels parameters for greatest polyphenolic yield were a proportion 1:30 g/mL, ethyl alcohol...

Dry-hopping process is the cold extraction of substances found in hops into beer. This method has gained popularity among beer brewers recent years because it aids introduction intense flavour and aroma fermented beverages. However, using a large amount hop material may result significant losses spent In this study, test batches hopped with recycled were made varying dosages material. Beers brewed had lower IBU (international bittering units) concentrations hop-derived volatiles (such as...

The aim of this research was to determine the potential four unconventional Norwegian yeasts KVEIK type produce NEIPA beer. influence yeast strains on fermentation process, physicochemical properties, antioxidant potential, volatile compounds, and sensory properties investigated. KVEIK-fermented beer did not differ in terms parameters from produced with commercial variants US-05 yeast. strain influenced quality (taste aroma) beers, rating significantly higher. activity tested beers also...

The development of craft brewing has spurred huge interest in unusual and traditional technologies ingredients allowing the production beers that would fulfil consumers’ growing demands. In this study, we evaluated performance Norwegian KVEIK yeast during Foreign Extra Stout beer. content alcohol KVEIK-fermented beer was 5.11–5.58% v/v, extract 5.05–6.66% w/w, pH value 4.53–4.83. able to completely consume maltose maltotriose. mean concentration glycerol higher than control sample (1.51 g/L...

Abstract The aim of the study was to use spent brewer’s yeast biomass (SBY) as a nutrient adjunct distillery type corn mashes improve process ethanol fermentation by Saccharomyces cerevisiae. There were prepared with raw material loading at 20% ww. SBY addition solids loadings 0 (control); 0.1; 0.5; 0.7; 1.0; 3.0 and 5.0% obtained inoculated subjected batch for 72 h. It observed that supplementation improved fermentation. consumption sugars production in supplemented accelerated overall...

The goal of this study was to evaluate the effect two-step whole rye meal fractionation by means sieving and alkaline extraction on efficiency ethanol production process in an integrated biorefinery scenario. It found that with sieve 1250 μm openings resulted obtaining a fraction increased starch content slight reduction arabinoxylan. Under optimized conditions (solids loading, temperature, pH, time) extraction, purified 0.75 g g−1 negligible amounts protein arabinoxylan obtained, together...
