Influence of wine fermentation temperature on the synthesis of yeast-derived volatile aroma compounds

…, JH Swiegers, C Varela, IS Pretorius, E Agosin - Applied microbiology …, 2007 - Springer
The yeast Saccharomyces cerevisiae synthesises a variety of volatile aroma compounds
during wine fermentation. In this study, the influence of fermentation temperature on (1) the …

Biomass content governs fermentation rate in nitrogen-deficient wine musts

C Varela, F Pizarro, E Agosin - Applied and environmental …, 2004 - Am Soc Microbiol
Problematic fermentations are common in the wine industry. Assimilable nitrogen deficiency
is the most prevalent cause of sluggish fermentations and can reduce fermentation rates …

Influence of sun exposure on the aromatic composition of Chilean Muscat grape cultivars Moscatel de Alejandria and Moscatel rosada

A Belancic, E Agosin, A Ibacache… - … Journal of Enology …, 1997 - Am Soc Enol Viticulture
The effect of sun exposure on the aromatic composition of two Muscat grape cultivars, Moscatel
de Alejandría and Moscatel rosada, was monitored over two seasons. Fully exposed and …

Quantitative analysis of red wine tannins using Fourier-transform mid-infrared spectrometry

K Fernández, E Agosin - Journal of Agricultural and Food …, 2007 - ACS Publications
Tannin content and composition are critical quality components of red wines. No spectroscopic
method assessing these phenols in wine has been described so far. We report here a …

Effects of temperature and time on polyphenolic content and antioxidant activity in the pressurized hot water extraction of deodorized thyme (Thymus vulgaris)

…, J Pérez-Jiménez, JL Torres, E Agosin… - Journal of agricultural …, 2012 - ACS Publications
The effects of temperature (50–200 C) and contact time (5–30 min) on the pressurized hot
water extraction of deodorized thyme were explored for antioxidant activity, polyphenol profiles…

Production and degradation of oxalic acid by brown rot fungi

E Espejo, E Agosin - Applied and Environmental Microbiology, 1991 - Am Soc Microbiol
Our results show that all of the brown rot fungi tested produce oxalic acid in liquid as well as
in semisolid cultures. Gloeophyllum trabeum, which accumulates the lowest amount of …

Effect of pressurized hot water extraction on antioxidants from grape pomace before and after enological fermentation

…, JL Torres, ML Mateos-Martín, E Agosin… - Journal of Agricultural …, 2013 - ACS Publications
Grape pomace was extracted with pressurized hot water at laboratory scale before and after
fermentation to explore the effects of fermentation and extraction temperature (50–200 C) …

A multipurpose portable instrument for determining ripeness in wine grapes using NIR spectroscopy

…, AR Guesalaga, E Agosín - IEEE Transactions on …, 2008 - ieeexplore.ieee.org
This paper describes the development of a noninvasive instrument that is designed to
measure three parameters of ripeness in wine grapes, ie, sugar (Brix), pH, and anthocyanin …

Changes in molecular size distribution of cellulose during attack by white rot and brown rot fungi

K Kleman-Leyer, E Agosin, AH Conner… - Applied and …, 1992 - Am Soc Microbiol
The kinetics of cotton cellulose depolymerization by the brown rot fungus Postia placenta
and the white rot fungus Phanerochaete chrysosporium were investigated with solid-state …

Differential synthesis of fermentative aroma compounds of two related commercial wine yeast strains

…, C Varela, JH Swiegers, IS Pretorius, E Agosin - Food Chemistry, 2009 - Elsevier
The specific impact of the yeast strain on the wine flavour and aroma has not been well
characterised yet because this effect is usually combined with other variables during the …
