This just in from AhtonicusCruxzonicus AKA Papa’s Glorious Beard on Reddit:

Someone was saying that they didn't like the itch from the pineapple and what to do about it?

Here's AhtonicusCruxzonicus' response:

Sensitive to Pineapple’s Acidity? Try This Bromelain Hack

AhtonicusCruxzonicus says: I core, peel and slice them straight into an ice cold citric acid, honey and salt water bath for about 3 to 5 minutes to perk the flesh up, disrupt the bromelain enzymes that makes them itchy to the mouth, and keep them from turning dark. I also slice them a bit thicker 1/2 or so for a crunchy /chewy mouth experience.

by the way...

That "acidic" sting you are talking about is caused by the Bromelain in the pineapple. Bromelain is an enzyme that eats through the mucous coating on the inside of your mouth, then gets to work on the exposed proteins (which is why it's so good at meat tenderizing.) It’s kind of horrific, but doesn’t cause any permanent damage as long as you don’t continue to eat fresh-pineapple-after-fresh-pineapple like a crazy person without stopping. The enzyme affects some people a more harshly than others, so it’s entirely possible that some will never even notice it at all.

This article from Science Meets Food claims that the dissolved sodium chloride disrupts the enzyme’s polarity, which will “destabilize the protein and denature its structure.” Michael Tunick, Ph.D., an assistant clinical professor of culinary arts and food science at Drexel University in Philadelphia told Food & Wine that salt “triggers bromelain to begin working, so by the time the pineapple reaches your mouth, the enzyme has been inactivated,” and that “dipping fresh pineapple briefly in a saltwater solution is the best way to maximize contact between salt and bromelain.”

  • Drying time: between 6-12 hours and up to 18-hours using the above instructions.
  • Dehydrated pineapple will feel leathery with no tackiness.
  • Remember to rotate your food dehydrator trays, for even drying.

How to Dehydrate Frozen Pineapple (The Right Way)

The way to dehydrate frozen (pre-packaged) pineapple, is to simply allow it to thaw in the fridge for 24 hours (or at a minimum overnight).

Drain away excess pineapple juice/ice water in a sieve in the sink.

Follow the "fresh" steps 2 through 3 above, assuming your thawed pineapple has already been cut into uniform pieces.

How to Dehydrate Canned Pineapple in 3 Easy Steps

And for canned pineapple? Simply drain the excess pineapple juice from the can as you pour the canned pineapple into a sieve in the sink* and then follow "fresh" steps 2 through 3.

Also, the acidity in pineapple makes it great for tenderizing meats for use in marinades, and for sweet and sour dishes like teriyaki chicken, or pork.

*Many people save the canned juice and enjoy it as a beverage with a bit of sparkling water added to it. Also, use the left-over pineapple juice in your next smoothie!

Want to Rehydrate Dried Pineapple? Here’s the Simple Trick

To rehydrate dehydrated pineapple, simply soak the pineapple - preferably in its own juice - until it plumps back up. Give it about 30 minutes or so.

When using plain water, if you need - or want - to add a little sweetness back in, add a bit of sugar or honey to the water, before rehydrating your dried pineapple.

Why Is Dried Pineapple a Go-To Hiking Snack?

Dehydrated pineapple is much sweeter than fresh pineapple due to the water having been evaporated - it condenses the sweetness.

Which U.S. States Are Best for Growing Pineapples?

  • Hawaii - The tropical climate of Hawaii provides ideal conditions for growing pineapples. The Hawaiian Islands have a long history of pineapple cultivation.
  • Florida - Southern Florida's warm climate allows fresh pineapple production, especially along the coasts. Major pineapple growers are located in Palm Beach County.
  • Texas - Pineapples are grown in the southernmost and warmest regions of Texas, such as around the Corpus Christi area.
  • California - Some specialty and ornamental pineapple growers cultivate pineapples in greenhouses in Southern California.
  • Puerto Rico - Puerto Rico has a good tropical climate for pineapple cultivation, especially in the central plains.
  • U.S. Virgin Islands - The hot and humid climate of the Virgin Islands enables pineapple production. Growers are located on St. Croix Island. Lucky people and pineapples!

The keys to successfully growing pineapples in the U.S. are temperatures above 65°F, high humidity, lots of sunshine, and protection from frost and cold winds. It makes sense, then, that commercial pineapple production thrives best in Hawaii and Florida.

Harvest Time: When Is a Pineapple Ripe and Ready to Pick?

  • Pineapples are ready to harvest when it has reached full size and maturity. It will be about 16-20 inches tall and weigh 2-4 lbs.
  • The skin color changes from green to yellow or orange hues. As the pineapple ripens, the skin color becomes more vibrant.
  • The fruit yields a sweet fragrance at the base near the first set of leaves. When lightly pulled, it should release with a bit of resistance.
  • The eyes on the pineapple skin are flat, not sunken or concave. The eyes turning concave is a sign of over-ripeness.
  • The leaves in the center of the plant begin to turn brown and wilt. But the leaves should still be somewhat firmly attached.

Ideally, pineapples should be harvested when the base turns yellow/orange and the aroma is present - but before over-ripeness sets in - for maximum sweetness and shelf life after picking.
