Chemical modeling for pH prediction of acidified musts with gypsum and tartaric acid in warm regions [PDF]

, 2015
Winemaking of musts acidified with up to 3 g/L of gypsum (CaSO4 2H2O) and tartaric acid, both individually and in combination, as well as a chemical modeling have been carried out to study the behaviour of these compounds as acidifiers.

Uncorking white wine liking: Combining analytical chemistry and chemometrics with crowd-sourced data to predict quality ratings [PDF]

Food Chemistry
Quality perception is a crucial aspect of wine research, particularly regarding consumer acceptance and quality impression. These assessments are challenging because consumers frequently incorporate extrinsic cues when evaluating hedonic quality. A unique perspective on wine quality is provided by the platform Vivino, which utilizes crowd-sourced ...

Analytic and quality control validation and assessment of field performance of a point‐of‐care chemistry analyzer for use in the White rhinoceros [PDF]

Veterinary Clinical Pathology, 2017
BackgroundA chemistry point‐of‐care analyzer would be useful for evaluating injured wildlife, particularly White rhinoceros (Ceratotherium simum) that survive poaching attempts. The IDEXX VetTest could be suitable, but species‐specific validation, development of a statistical quality control (QC) strategy, and evaluation under field conditions are ...
