Are pyranoanthocyanins involved in sensory effect in red wines?

BIO Web of Conferences, 2016
During the wine-making process and ageing, the formation of various groups of pyranoanthocyanins leads to enhance and to stabilize the red wine colour. Although their chemical properties and their formation kinetics have been well-described, data about ...

Wine and Grape Tannin Interactions with Salivary Proteins and Their Impact on Astringency: A Review of Current Research

Molecules, 2011
Astringency is an important characteristic of red wine quality. The sensation is generally thought to be produced by the interaction of wine tannins with salivary proteins and the subsequent aggregation and precipitation of protein-tannin complexes.

Sulfur isotopes from the Paleoproterozoic Francevillian Basin record multigenerational pyrite formation, not depositional conditions

Communications Earth & Environment
Bulk-rock sulfur isotope data from pyrite in the ~2.1 billion-year sedimentary rocks of the Francevillian Basin, Gabon, have underpinned ideas about initial oxygenation of Earth’s surface environments and eukaryote evolution.

Mixotrophic Growth Under Micro-Oxic Conditions in the Purple Sulfur Bacterium “Thiodictyon syntrophicum”

Frontiers in Microbiology, 2019
The microbial ecosystem of the meromictic Lake Cadagno (Ticino, Swiss Alps) has been studied intensively in order to understand structure and functioning of the anoxygenic phototrophic sulfur bacteria community living in the chemocline. It has been found

Optimization of dry fractionation and micro-oxidation flavor enhancement for beef tallow combined with storage stability study

Food Chemistry: X
This study developed functional beef tallow with reduced saturation, improved flavor, and enhanced storage stability through optimized dry fractionation (44 °C, 8 h, 6 °C/h) and micro-oxidation (150 °C, 40 min, 130 L/h).
