Authentication of volatile and non-volatile compounds in Robusta Java Bogor as a differentiator in post-harvest processes [PDF]

BIO Web of Conferences
Whether the post-harvest process will greatly influence volatile or non-volatile coffee chemical compounds. Four post-harvest coffee processing techniques, namely natural, honey, fullwash, and wine, were evaluated in this study.

Identification, Comparison and Classification of Volatile Compounds in Peels of 40 Apple Cultivars by HS–SPME with GC–MS

Foods, 2021
Aroma is an important quality indicator for apples and has a great influence on the overall flavour and consumer acceptance. However, the information of the aroma volatile compounds in apple peels is largely unknown. In this study, evaluation of volatile

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Modulating the sulfurization procedure to decrease by-product formation for one-step catalytic synthesis of sulfur-containing chemicals

Fuel Processing Technology
The one-step synthesis of sulfur-containing chemicals, methanethiol (CH3SH), from syngas and hydrogen sullfide (H2S) mixtures shows the enormous potential for extending the application of both C1 chemistry and sulfur resource recycling and utilization ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

De novo synthesis of short‐chain aldehydes and hydrocarbons secreted by the brown marmorated stink bug Halyomorpha halys

FEBS Open Bio, EarlyView.
The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.
