Taste leaves a lasting impact, so flavor changes can negatively influence repeat purchasing decisions. Since oxidation changes both color and flavor, it affects the consumer decision-making process in two ways:. Oxidation is the enemy, but it can be prevented or delayed through a variety of techniques, including processing techniques, packaging and storage methods such as modified atmosphere packaging MAP , and the use of antioxidant ingredients.
Antioxidant ingredients provide the most cost-effective oxidation prevention method due to their level of effectiveness, their lack of negative impact on flavor, and their ability to provide targeted solutions.
Antioxidants delay the onset of oxidation by donating hydrogen atoms to quench free radicals, forming a stable antioxidant radical that is unable to participate in propagation reactions, slowing down oxidation. Avoiding oxidation of white wine must be one of the priorities for winemakers and must and wine producers. This prevents the appearance of negative symptoms in color, flavor and aroma that may affect its tasting.
Controlling nitrogen levels and other elements such as catechins; using equipment to monitor the RedOx potential; taking care of other aspects such as temperature, tank filling level and using specific antioxidants are also fundamental aspects to control the occurrence of an oxidation process.
