The global sulfur cycle is largely influenced by the production of dimethyl sulfide (DMS), which is primarily generated through the enzymatic cleavage of algal dimethylsulfoniopropionate (DMSP). This study presents an efficient and simplified method for analyzing DMSP lyase activity (DLA) by measuring the conversion efficiency of DMSP to DMS using ...

Cooked poultry products are nutritious and economically valuable products that are at risk of bacterial spoilage, which can be postponed by cooling and modified-atmosphere-packaging (MAP). In this study, a cooked chicken product was stored at three different temperature ranges (4-6 °C, 7-9 °C, and 11-13 °C) and volatile production was measured over ...

The ingestion of relatively large doses of the vitamin niacin by healthy volunteers results in a reddening of the skin, a skin 'flush'. Thus, we have carried out a study of the breath metabolites of two healthy volunteers following (i) the ingestion of 200 mg of immediate-release niacin, (ii) as (i) but preceded by the ingestion of 325 mg of aspirin ...

Alcohols are often present in foods and other biological media, including exhaled breath, urine and cell culture headspace. For their analysis by selected ion flow tube mass spectrometry (SIFT-MS), the ion chemistry initiated by the reactions of the reagent ions H3 O+ and NO+ with alcohol molecules in the presence of water molecules needs to be ...

Journal of Breath Research
Abstract The measurement of trace breath gases is of growing interest for its potential to provide non-invasive physiological information in health and disease. While instrumental techniques such as selected-ion flow-tube mass spectrometry (SIFT-MS) can achieve this, these are less suitable for clinical application.
