Mold-ripened cheeses exhibit complex mechanical behavior, influenced by factors such as degree of ripening, water content, fat and type mold (white or blue). This study explored the viscoelastic behavior four types mold-ripened to highlight their physicochemical properties, taking into consideration that viscoelasticity influences texture, stability during storage processing. Analyzing local pressures applied cheese samples, for a contact surface with samples approximately 51.5 mm², pressure...
This paper presents an analysis of the literature that studies possibility sewage sludge being used in cement industry to reduce carbon dioxide emissions from production and thus solve problem disposing so it is no longer stored, avoiding soil pollution with heavy metals, reducing pressure on environment. The ash a good pozzolanic material, because when finely ground, can be as partial substitute for Portland cement. reduces waste storage costs. Sewage was mixed cement, analyzed determine...
Given the energy crisis and climate change due to pollution, given that largest emissions of greenhouse gases are produced by industry, we must turn our attention efficient use solar energy, which is cleanest most abundant all renewable energies. In this paper, based on an analysis specialized literature, studied effect dust accumulation surface photovoltaic modules some performance characteristics efficiency these panels compared clean modules. We analyzed cause influence tilt angles...
In this study, three types of extracts isolated from leaves Plantain (Plantago lanceolata) were tested for their chemical content and biological activities. The bioproducts are combinations polysaccharides polyphenols (flavonoids iridoidic compounds), they antioxidant, antifungal, antitumor, prebiotic activity (particularly fraction). Briefly, the iridoid-enriched fraction has revealed a pro-oxidant activity, while flavonoid-enriched had high antioxidant potency; polysaccharide also...
Various types of functional yogurts were obtained from normalized milk (with lipid content) and a standardized probiotic consortium bacteria named ABY3. All the contained prebiotics black or red rice; malt barley, rye, wheat; wheat bran. The physico-chemical analyses all functionalized products showed that them met quality standard for yogurt products. However, sensorial rice very good quality. biological indicated live bacteria, but bran could increase their numbers. Tests performed on...
The current study evaluated the effect of powder fractions based on particle size chemical composition macronutrients such as proteins and sugars, phytochemical properties (total content polyphenolic compounds, vitamin C antioxidant activity), preservation capaci-ty (water reconstitutability absorption capacity water solubility index) physicochemical (particle distribution moisture content) black-thorn berries (Prunus spinosa) powders. fruits were separated from plant material seeds, dried...
The current study evaluated the effect of powder fractionation based on particle size chemical composition macronutrients such as proteins and sugars, phytochemical properties (total content polyphenolic compounds, vitamin C, antioxidant activity), preservation capacity (water functional absorption water solubility index), physicochemical (particle distribution moisture content) blackthorn berry (Prunus spinosa) powders. fruits were separated from plant material seeds, dried, then ground...
The objective of our research was to evaluate the possible alteration organoleptic properties eggs produced by hens (Lohmann Brown-Classic) fed with diets containing different doses an industrial by-product enriched organic zinc (Zincoppyeast, ZP): Control 0%, ZP 2.5%, and 5.0%. Eggs were collected after 30 days (batch 1) 60 2) feeding experimental subjected chemical, microbiological, human sensory, e-nose, e-tongue analyses. There no significant difference among microbiological status three...
Yeast (including brewing yeast) and yeast-based preparations derived from bioprocesses or agroindustrial byproducts represent valuable feed additives ingredients for ruminants. The optimization of yeast biotechnological processing through fermentation mediated by the strain Saccharomyces pastorianus ssp. carlsbergensis W34/70 was investigated. cultivation conditions (temperature, pH, carbon source, nitrogen source) were selected designed according to a Taguchi fractional experimental plan,...
In this paper is analysed the air quality in urban areas Bucharest, analysis was based on monitoring of average concentration particulate matter PM 10, nitrogen oxides, NO2, and sulfur dioxide, SO2 Bucharest between 2009-2015. The refers to maximum 24 h occurrence overruns beyond limit set. It also looked at wind regime, temperature influence pollution
Abstract Fermented mashes based on different cereal grist are a healthy and nutritious beverage, source for new functional products with beneficial effects human health. These thick consistency sour-sweet taste, colors depending the ingredients method of preparation. In this study were determined main physical chemical characteristics (pH, volatile total acidity, soluble dry substances, alcohol concentration, dynamic viscosity) was made sensorial analysis some boiled aqueous obtained from...
This study presents the behavior of identified yeast strain S. cerevisiae, isolated from Busuioacă de Bohotin grapes Pietroasa winery, during process fermentation to obtain dry active biomass for winemaking process. In this respect, we promoted an optimization strategy obtaining biomass. The cultivation conditions micropilot (temperature, pH, carbon source, and nitrogen source) were selected designed according a Taguchi design with four factors three levels. Reproducibility testing was...
Consumers are increasingly demanding traditional beverages such as wines that obtained through innovative technologies and use indigenous yeasts to preserve the concept of `terroir`. The paper presents study performed for exploitation microbial diversity in Pietroasa wine region Romania obtain autochthones biomass. Yeasts were isolated from grapes must Feteasca regala FR) Cabernet Sauvignon (CS) varieties cultivated at Viticulture Vinification Research Development Station. Five yeast...
The grape surface hosts a complex community of yeast Saccharomyces and non-Saccharomyces species responsible for spontaneous alcoholic fermentation in wine industry. strains used this study were isolated from ‘Tămâioasă Românească’ ‘Busuioacă de Bohotin’ varieties Pietroasa vineyard, the isolates identified through molecular method. Identification BLASTn analysis 5.8S-ITS region revealed that PFE5 strain showed best sequence match to cerevisiae (98% similarity) PFE15 Starmerella bacillaris...
