Everything you need to know about pineapple! Why does it hurt your mouth? How do you know when it’s ripe? All your questions answered here!

Eatmail subscribers already know that I am super excited about this spotlight ingredient, because after much deliberation, I think I can say pineapples are my favorite fruit.

But first, we must answer the most pressing question…

Why does pineapple make my mouth hurt?

Fresh pineapple contains an enzyme called bromelain, which breaks down proteins. So essentially, the enzyme is working away at your mouth as you chew the pineapple, which can cause some irritation, tingling, or pain.

Once you swallow the pineapple, your stomach has what it needs to protect itself from bromelain, so fear it not! In fact, bromelain may even help reduce inflammation in other areas of the body, like in joints and soft tissue, sinuses, and intestines.

How to pick the perfect pineapple

Contrary to popular belief, pineapples do not ripen after they are picked, which means youโ€™ll want to pick the ripest one when purchasing. There are a few ways to determine if it’s ripe (hint: the external color of the fruit doesnโ€™t necessarily indicate ripeness):

  1. Smell the bottom. If it smells strong, sweet, and fragrant, itโ€™s probably ripe. No smell? Not ripe!
  2. Pluck a leaf from the center of the crown. If it comes out easily, itโ€™s probably ripe.

How To Store Pineapples

Because pineapples donโ€™t ripen after being picked, they can only get less tasty with age, so proper storage is essential! You can store pineapple in a few ways:

  • Room temperature: You can store uncut pineapples at room temperature for about 3 days.
  • Refrigerated: You can also store uncut pineapples in the warmest part of your fridge (usually the top), where they will last longer (though the leaves and outer skin may brown slightly). Cut pineapple should always be stored in an airtight container in the fridge or freezer.

    I have 2 pineapples almost ripe. When do I cut the pups or slips off? They are right under the pineapples .

    1. Sarah says:

      Once they’re about 8 inches or so (or about 1/3 to 1/2 of the mother’s size). ๐Ÿ˜€

  2. Patty says:

    I need to make a pineapple boat for a party, but need to make it in advance. How can I keep it from browsing?

    1. Sarah Bond says:

      Anything with ascorbic acid (like orange juice) will prevent browning. Just splash it all over the cut side of the fruit!

  3. Erika says:

    Aloha From Hawaii. So one more tidbit, once you cut the crown off the pineapple turn it upside down and let it sit for 30mins. This will allow all the yummy juice to flow through the whole pineapple making all the fruit nice and sweet. Make sure to put the pineapple on a plate first though otherwise, you’ll have juice everywhere!

  4. Holly Belle says:

    Can i store fresh cut pineapple in some sort of Juice in my refrigerator for a week, similiar to ‘Pineapple spears in coconut water’ that Sams club sells? I like a slice of pineapple with my breakfast each day.

    1. Sarah Bond says:

      I think that would work well! Acidic juice, like orange or pineapple, would probably keep it fresh for longer.

  5. Faith says:

    How do you know if pineapple is bad

    1. Sarah Bond says:

      Pineapple will usually be discolored and have a fermented smell when it is bad.

    2. Balakrishna says:

      If I cut the pine apple into two halves and I didn’t peel it off. So will it be okay for just one day???

    3. Sarah Bond says:

      It should be okay!

      Theyโ€™ll usually be called Megan

  6. Charles L says:

    They do ripen after you pick them. If you let them ripen to much they WILL get eaten by a animal.

  7. Linda says:

    It seems to me that “Everything you need to know about pineapples” should include how to cut them up into edible pieces.

  8. Karen says:

    What makes pineapple give off a chemical smell?

    1. Sarah Bond says:

      I’m honestly not sure! It could be that it’s begun to ferment?

  9. Angela B says:

    I have been seeing different images of pineapples everywhere I go for about 2 days. They have just been jumping out at me. I finally realize I am being given a message so I googled pineapple and found your website. I have yet to decide the message but it has my attention! Thank you for your website!
