Does lemon juice prevent wine from oxidating?

[vikingblood666]

I know if u put lemon juice on apples it prevents them from oxididating and turning brown would it work for wine?

No, not at all. With apples and potatoes the citric acid in lemon juice lowers he pH to the point where enzymes stop working. Oxidation in wine is a different mechanism.
