Protecting wines from pollution and contamination is fundamental, in order to avoid spoilage and preserve the quality and integrity of bottled wines. Through experimental activity the effectiveness...
Shelf-life is a very generalized notion that encompasses a lot of areas of wine quality, wine distribution and wine commerce. Shelf life is a projection, it’s something that happens in the future. ...
The use of pulsed light (PL) in food technology dates back to the 1970s. New research shows PL may not modify the product sensorial properties nor its nutrimental benefits but would afford the redu...
Screw caps differ in the oxygen barrier effect of their sealing inserts. Too much oxygen promotes oxidative ageing, too little oxygen promotes reductive ageing. Reductive ageing under hermetically ...
