Question

If you add lemon juice to peeled fruit it keeps it from darkening. why does lemon juice keep fruit from darkening?

Answer 1

The acid in the lemon prevents the growth of bacteria which turns the fruit dark as it starts the decay process.

Answer 2

because lemon juice has an ascorbic acid also known as vitimin C. that's the main reason why lemon keeps other fruit (if u put it) from darkening but of course their are other factors that contribute a fruit from darkening this are copper, oxygen, substrate and an enzyme... hope that would help

Answer 3

When air hits the peeled fruit, it causes oxidation and turns brown. Lemon juice reduces oxidation and keeps it from turning brown.

Answer 4

I agree with daft one. Anything acidic will stop oxidation. Only you wouldn't want to use any old acid - it could be toxic.

Answer 5

the acid keeps it from doing that
