Why does guacamole turn darker the next day even after being refrigerated? How long is it good for?

Question

If you keep guacamole refrigerated in a covered container, why does it turn darker the next day? And is it still good? For how long?

Answer 1

Because the avocado is exposed to oxygen and it oxydizes.

You can prevent this by covering your guacamole with plastic wrap that is pushed right down on top of the guacamole.

For homemade guacamole, I'd be suspicious after 3 days, and toss it without regard to looks after seven days. Commercially prepared guacamole might last a day or two longer, but I'd be leary of anything that has been opened and in the frige for more than a week.

Answer 2

It's called "oxidation". It's what happens when certain foods are exposed to air. Try sprinkling the top of your guac with lemon or lime juice and/or placing plastic wrap right on top to keep the air out. Should last 2-3 days.

Answer 3

guacamole is just like apples, once it has been exposed to oxygen it browns. it is still fine. i would say as long as it is refrigerated it's okay to eat for 5 days.

Answer 4

as quickly as you're making the Guacamole, you may desire to drop between the avocado pits interior the midsection of the dip. you may positioned it below the dip or on staggering. The pit keeps the dip from turning brown. reliable success.

Answer 5

It's oxidation- just like apples turn brown when exposed to air, so do avocados. It's perfectly safe to eat for 1-2 days.

Answer 6

When cut, rub with lemon or lime and wrap tightly and refrigerate, good for a few days.

Answer 7

Oxidation
you should have added some Flavor Fresh or Ever Fresh.
did you use a 'real" air tight container rubber maid or tupperware??
It should be good just mix well
