The high loss rate of bread is generally known to contribute the alarmingly numbers in worldwide food waste. Correct storage techniques are believed enable reduction preventable Therefore, influence parameters on staling and spoilage behavior German within limits common household methods was investigated this study. aim generate reliable data for using different (PE-layered microperforated paper bag, plastic fridge box) bridge gap between consumer’s needs scientific research questions....
A novel millifluidic magnetophoresis approach can be used to fractionate yeast cells according their individual cell age. Old and young show different behavior in gene expression metabolome.
Despite the fact that yeast is a widely used microorganism in food, beverage, and pharmaceutical industries, impact of viability age distribution on cultivation performance has yet to be fully understood. For detailed analysis fermentation physiological state, we introduced method magnetic batch separation isolate daughter mother cells from heterogeneous culture. By binding functionalised iron oxide nanoparticles, it possible separate chitin-enriched bud scars by way linker protein. This...
For industrial processes, a fast, precise, and reliable method of determining the physiological state yeast cells, especially viability, is essential. However, an increasing number processes use magnetic nanoparticles (MNPs) for cell manipulation, but their impact on viability assay itself unclear. This study tested Saccharomyces pastorianus ssp. carlsbergensis Pichia pastoris by comparing traditional colourimetric, high-throughput, growth assays with membrane fluidity. Results showed that...
Food-derived peptides with an inhibitory effect on dipeptidyl peptidase IV (DPP-IV) can be used as additive treatment for type 2 diabetes. The potential of food depends technological protein hydrolysis and gastrointestinal digestion, the only act after intestinal resorption. malting a hydrolytic step availability these in grains has yet to investigated. In this study, quinoa was malted under systematic temperature, moisture, time variations. resulting malts, DPP-IV inhibition reached maximum...
The brewing industry is facing an ever increasing challenge to become more cost-effective, while at the same time maintaining or improving product quality. Brewing with unmalted oats (Avena sativa L.) has potential reduce costs of raw materials. However, replacement malted barley can also adversely affect quality and processability mashes, worts, beers. In this study, (0–40%) was carried out in a 60-L pilot plant. impact various levels on mashing, lautering, fermentation performance...
Flow cytometry is a powerful tool for identifying and quantifying various cell markers, such as viability, vitality, individual age, at single-cell stages. However, autofluorescence marker fluorophore signals overlap low fluorescence intensities. Thus, these must be unmixed before determining the age fraction.A comparison was made between principal component regression (PCR) random forest (RF) to predict of Saccharomyces pastorianus var. carlsbergensis in flow cytometer. RF provided better...
The physiological and metabolic diversity of a yeast culture is the sum individual cell phenotypes. As well as environmental conditions, genetics, numbers divisions, major factor influencing characteristics age. A postcytokinesis bud scar on mother cell, benchmark in replicative life span, quantifiable indicator age, characterized by significant amounts chitin. We developed binding process for visualizing scars Saccharomyces pastorianus var. carlsbergensis using protein linker containing...
Abstract Gluten-free beer (GFB) was produced from gluten-containing barley malt wort by adding an enzyme-enriched extract to the wort, intended for patients with celiac disease. Nevertheless, aroma profile of such is unknown. The results indicated that treatment reduced 3-methylbutyl acetate, 2-methylbutyl ethyl hexanoate, 2-methylpropyl and butyrate when compared reference. Moreover, foam, free amino nitrogen, aging stability, color deviated significantly in GFB. Although values were below...
Consumer health concerns and regulatory policies lead to a growing demand for sugar-sweetened beverage alternatives. A reduced energy content can be achieved using artificial sweeteners, which often also convey metallic or bitter off-flavor. Therefore, the alteration of sweetness perception masking potential off-flavors are paramount improving sweet beverages. Trigeminal stimuli, such as capsaicin (spicy) menthol (cooling), have been used influence taste in food items, although their use...
Abstract Downscaling the anaerobic fermentation in a microtiter plate (MTP) facilitates high throughput screening (HTS) applications. This study investigates impacts of MTP configurations (scale, shaking, and cover) on S. pastorianus beer compared to that shaking flask (SF) European Brewing Convention (EBC) tube regarding performances flavor attributes. The lager strains MTPs accelerated cells reproduction vitalization, sugar consumption, glycerol accumulation. microscale was closer SF but...
