Vitamin C against blackening
You've probably heard of this tip: to prevent fruit or vegetables from turning brown or black, simply add or sprinkle lemon juice over them.
It's very effective, but why does lemon juice have this effect?

Vitamin C against blackening
Well, that's because it contains vitamin C, which acts as an antioxidant, not the lemon itself or its acidity.
Let's imagine you want to make a fruit purée, for a sorbet or a fruit coulis, pears for example: you peel the pears, remove the cores and blend the whole thing, it's very simple.
The problem is that the pear purée will oxidize very quickly and change color, while the taste will not change (or only slightly), but it will be less appetizing.
Here's the trick: add a pinch of vitamin C to your fruit purée (as you blend), and the result is spectacular.
Finally, a few examples of fruits and vegetables where vitamin C works wonders: avocados in guacamole, raw peeled purple artichokes (soaked in water with a pinch of vitamin C), strawberry or apricot coulis, etc.
As a general rule, whenever you have to soak something (vegetables or fruit) to prevent browning, systematically add a pinch or two of vitamin C to the water. You'll be amazed at how effective it is.
To sum up: a pinch of vitamin C in a preparation is highly effective in preventing the browning of fresh produce.
