in this study a new simple selective and sensitive spectrophotometric procedure for determination of fe(iii) is described. it is based on the formation of a colored complex between ferric iron and ethyl maltol, a strong and highly selective ligand for fe(iii). after mixing sample and reagent, and incubating at the room temperature, fe(iii)-ethyl maltol complex was extracted with different solve...

Development of lanthanide detoxification agents and protocols is of great importance in management of overdoses. Due to safety of maltol as a detoxifying agent in metal overloads, it can be used as a lanthanide detoxifying agent. In order to demonstrate the biodistribution of final complex, [(153)Sm]-samarium maltolate was prepared using Sm-153 chloride (radiochemical purity >99.9%; ITLC and sp...

The impact of olfactory perception on sweetness was explored in a model solution using odorants at subthreshold concentrations. First, the impact of 6 odorants, previously described in the literature as congruent with sweetness, was investigated at suprathreshold level in a sucrose solution. Ethyl butyrate and maltol were selected as they had the highest and the lowest sweetness-enhancing prope...

Recent studies suggest that electronic cigarette (e-cig) flavors can be harmful to lung tissue by imposing oxidative stress and inflammatory responses. The potential inflammatory response by lung epithelial cells and fibroblasts exposed to e-cig flavoring chemicals in addition to other risk-anticipated flavor enhancers inhaled by e-cig users is not known. The goal of this study was to evaluate ...

Abstract An odorant screening by gas chromatography–olfactometry (GC–O) and a crude aroma extract dilution analysis (AEDA) applied to the volatiles isolated from light dark liquid malt (LME) solvent extraction solvent-assisted flavour evaporation (SAFE) identified 28 odorants. Fifteen major odorants were subsequently quantitated odour activity values (OAVs) calculated as ratio of concentration ...

High hydrostatic pressure (HHP) is an attractive method for food preservation due to resulting improvements in the quality characteristics of foods, in addition to microbial inactivation. This study aimed at improving the nutraceutical potential of red ginseng (Panax ginseng C.A. Meyer). HHP treatment of 600 MPa for 1 min at room temperature in conjunction with conventional steaming and drying ...

Maltol, mostly used as a flavoring molecule, also has various potential applications biomedical compound. Despite its extensive use in the food industry, maltol’s antimicrobial activity was evaluated only briefly, and suggested to be insufficient on own. Recently, we have shown that maltol can conjunction with cationic surfactant species receive higher against contaminant microorganisms. In thi...
