Aroma profile is one of the main features for the acceptance of wine. Yeasts and bacteria are the responsible organisms to carry out both, alcoholic and malolactic fermentation. Alcoholic fermentation is in turn, responsible for transforming grape juice into wine and providing secondary aromas. Secondary aroma can be influenced by different factors; however, the influence of the microorganisms is one of the main agents affecting final wine aroma profile. has historically been the most used yeast for winemaking process for its specific characteristics: high fermentative metabolism and kinetics, low acetic acid production, resistance to high levels of sugar, ethanol, sulfur dioxide and also, the production of pleasant aromatic compounds. Nevertheless, in the last years, the use of non-saccharomyces yeasts has been progressively growing according to their capacity to enhance aroma complexity and interact with , especially in mixed cultures. Hence, this review article is aimed at associating the main secondary aroma compounds present in wine with the microorganisms involved in the spontaneous and guided fermentations, as well as an approach to the strain variability of species, the genetic modifications that can occur and their relevance to wine aroma construction.

Aims: Type 2 diabetes (T2D) related cognitive impairment links to comorbid and modifiable olfactory dysfunction; however, the efficacy of olfactory training (OT) to mitigate cognitive decline specifically in these patients with mild cognitive impairment (MCI) remains unestablished. This study aimed to determine whether OT alleviates cognitive decline in this population.
Materials And Methods: In this 16-week, open-label trial, 60 T2D participants with MCI were randomly assigned (1:1) to OT or routine care (control).

Tea trichomes, rich in secondary metabolites, are hypothesized to significantly influence white tea aroma, yet their biochemical contributions remain unclear. This study investigated the volatile profiles of tea trichome and tea body across six white tea samples using headspace solid-phase microextraction combined with gas chromatography-mass spectrometry (HS-SPME-GC-MS) and multivariate statistical analysis. Comparative analysis revealed significant differences in the volatile profile between tea trichome and tea body in all tested samples, with major differences lying in the content of volatile components.

This study investigated the generation patterns of spoilage off-odors in spiced beef (SB) caused by surviving bacteria under different thermal treatments at 80°C (T80), 95°C (T95), and 110°C (T110). The initial indicator of spoilage manifestation in all the SB samples was the emergence of off-odor. From these spoiled samples, only Bacillus spp.

This study elucidates the temperature-dependent interactions between halotolerant yeasts and microbial communities during secondary fortified soy sauce fermentation (SFFSS) and their implications for flavor enhancement and safety. A dual-mode fermentation system compared natural temperature fermentation (NTF) and controlled temperature fermentation (CTF, 30 °C), each with and without co-inoculation of Zygosaccharomyces rouxii and Wickerhamiella versatilis (ZC). Multi-omics analyses integrating amplicon sequencing, metagenomics, and metabolomics revealed that CTF control elevated amino acid nitrogen and aroma compounds, while increasing biogenic amines (BA) by 47.
