Exploring the biodiversity of two groups of Oenococcus oeni isolated from grape musts and wines: Are they equally diverse?
(Elsevier Gmbh, 2017-01)
One hundred and four Oenococcus oeni isolates were characterised by the carbohydrate fermentation (CH) profile and DNA fingerprinting. Forty-four isolates came from grape must, and 60 from wines sampled at the end of ...
Characterization of Cladosporium Rot in Grapevines, a Problem of Growing Importance in Chile
(AMER PHYTOPATHOLOGICAL SOC, 2008)
Cladosporium rot (Cladosporium spp.) of grapevine (Vitis vinifera) is a common disease in Chile, particularly in Cabernet Sauvignon and other red wine grape cultivars. It is favored by delayed harvest to obtain the phenolic ...
Oxidative enzymes and functional quality of minimally processed grape berries sanitised with ozonated water
(Wiley, 2018-06)
Thompson Seedless (TS) and Black (BS) grapes sanitised with 2, 4, 6, 8 mg L-1 O-3 or NaOCl (100 mg L-1) were stored 21days at 5 degrees C. Ozonated water stimulated the respiration rate, especially after 5 days of storage, ...
Isolation and characterization of latent and active polyphenoloxidase in BRS Clara (CNPUV 154-147 x Centennial seedless) and BRS Morena (Marroo seedless x Centennial seedless) seedless table grapes
(Elsevier France-editions Scientifiques Medicales Elsevier, 2011-11-01)
The seedless grapes BRS Clara and BRS Morena, developed in Brazil, are currently growing in popularity due to their premium texture and taste. However, there are no reports on the polyphenoloxidase (PPO) from these cultivars. ...

A multi-objective approach for supporting wine grape harvest operations
(2020)
In this paper, we present a novel multi-objective mixed-integer linear programming model to support wine grape harvesting. The proposed model considers the opposing nature of operational cost minimization and grape quality ...
The improvement of grape juice quality using Thermomucor Indicae-Seudaticae pectinase
(2020-04-01)
The effect of pectinolytic enzyme preparation (PEP) produced by the fungus Thermomucor indicae-seudaticae-N31 (PEP-N31) on total phenolic content, concentrations of methanol and color of grape juice was studied. Positive ...
A multipurpose portable instrument for determining ripeness in wine grapes using NIR spectroscopy
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
This paper describes the development of a noninvasive instrument that is designed to measure three parameters of ripeness in wine grapes, i.e., sugar (Brix), pH, and anthocyanin concentration. The instrument is based on ...
