The biological and organoleptic properties of Bulgarian yogurt are largely determined by the metabolic activity selected strains Lactobacillus delbrueckii ssp. bulgaricus. HS-SPME-GC-MS technique was used to analyze volatile compounds produced following strains: bulgaricus MG1, MG2, MG3 MG4, MG5 MG6, MG7 MG8. A study optimize conditions SPME performed. optimum extraction aromatic components obt...

A microbial community is engaged in a complex economy of cooperation and competition for carbon and energy. In engineered systems such as anaerobic digestion and fermentation, these relationships are exploited for conversion of a broad range of substrates into products, such as biogas, ethanol, and carboxylic acids. Medium chain fatty acids (MCFAs), for example, hexanoic acid, are valuable, ene...

BACKGROUND/AIMS To evaluate associations between delayed gastric emptying (GE) assessed by the octanoic acid breath test and upper gastrointestinal (GI) symptoms. METHODS A historical, prospective study included 111 consecutive symptomatic adults referred for a GE breath test because of upper abdominal symptoms suggestive of delayed GE. Exclusion criteria included underlying organic disease a...

This paper reports the application of hydrophobic deep eutectic solvents (HDES) as an environmentally friendly alternative for liquid-phase microextraction (LPME) Allura Red AC and Tartrazine in food products spectrophotometric determination these analytes. The HDES used this work were prepared by mixing octanoic acid (OctAc) or decanoic (DecAc) tetrabutylammonium bromide (N4444-Br) a molar rat...
