Applications of Liquid-Phase Microextraction in the Sample Preparation of Environmental Solid Samples

open access: yesMolecules, 2014
Solvent extraction remains one of the fundamental sample preparation techniques in the analysis of environmental solid samples, but organic solvents are toxic and environmentally harmful, therefore one of the possible greening directions is its ...

Unlocking fruit dimensions: Quantification of functional traits driving plant–frugivore interactions

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Fleshy fruits attract animals to ingest fruit, swallow the seeds, and release them in the landscape, thus facilitating seed dispersal and plant regeneration. Attraction of animal dispersers is achieved via attractants such as color or scent, and rewards like sugars, lipids, and micronutrients.

Headspace analysis of natural yoghurt using headspace solid phase microextraction : a thesis presented in partial fulfilment of the requirements for the degree of Master of Philosophy in Food Technology at Massey University (Turitea Campus), Palmerston North, New Zealand [PDF]

open access: yes, 2001
The Solid Phase Microextraction (SPME) method was originally developed to extract volatile and semivolatile compounds from wastewater samples but has since been applied to flavour compounds in foods and beverages.

Bacteria isolated from Bengal cat (Felis catus × Prionailurus bengalensis) anal sac secretions produce volatile compounds potentially associated with animal signaling. [PDF]

open access: yes, 2019
In social animals, scent secretions and marking behaviors play critical roles in communication, including intraspecific signals, such as identifying individuals and group membership, as well as interspecific signaling.

Assessment of Metabolites in Noni Fruit Slurry Fermented With Four Non‐Saccharomyces Yeasts

open access: yesFood Frontiers, EarlyView.
Dried noni fruit slurry (DNFS) was fermented for 14 days with selected non‐Saccharomyces yeasts. GCMS, HPLC and amino acid analysis showed that Pichia kluyveri Frootzen and Williopsis saturnus NCYC22 grew well, reduced off‐flavor fatty acids, generated fruity aroma compounds and preserved total phenolic content. ABSTRACT Noni products often suffer from
