Title: High Hydrostatic Pressure technology on wine: potentialities and drawbacks
During last years, scientific research on high hydrostatic pressure (HHP) as a non-thermal processing technology for preservation or aging of wine has increased substantially. HHP at pressures between 200 and 500 MPa are able to inactivate bacteria and yeasts in red and white wines, suggesting that it may be used for wine preservation. However, these treatments have been shown to promote changes on sensorial and physicochemical characteristics in both red and white wines, not immediately in the first month, but along storage. The changes are observed in wine colour, aroma and taste due mainly to reactions of phenolic compounds, sugars and proteins. These reactions have been associated with those observed during wine aging, leading to aged-like wine characteristics perceived by sensorial analysis (Nunes et al., 2017). The appropriate use of HHP, based on the scientific knowledge of the reactions occurring in wine promoted by HHP, will allow to exploit this technology for wine production achieving distinct characteristics to address particular market and consumer demands.
