Why Should You Soak Pineapple in Salt Water Before Eating It?

I was cutting up a fresh pineapple for my kids when my husband’s grandmother stopped me.

She told me to soak the pineapple pieces in salt water first.

I had never done that before, so naturally I asked why. She laughed and said that younger generations don’t always know the little food-preparation tricks that older generations learned over the years. 🍍

So what does soaking pineapple in salt water actually do?

🍍 The Reason Behind the Trick

Fresh pineapple contains an enzyme called bromelain. This enzyme can break down proteins, which is one reason fresh pineapple can sometimes leave your mouth feeling slightly irritated or “tingly” after eating a lot of it.

A mild salt-water soak is a traditional preparation method that some people use to make fresh pineapple more pleasant to eat.

It may also help reduce some of the sharpness of the pineapple’s flavor.

🧂 How to Do It

It’s very simple.

Step 1

Cut and peel the pineapple, then remove the tough core.

Step 2

Cut the fruit into bite-sized pieces.

Step 3

Fill a bowl with cool water and add a small amount of salt.

Step 4

Place the pineapple pieces in the salt water for several minutes.

Step 5

Drain and rinse the pineapple with clean water before serving.

You don’t need a highly concentrated salt solution. A little is enough.

👅 Why Does Pineapple Make Your Mouth Tingle?

That familiar tingling sensation is often associated with bromelain and the acidity of pineapple.

Bromelain is a group of enzymes naturally found in pineapple. Because it acts on proteins, fresh pineapple can interact with proteins on the surface of the mouth.

This is one reason some people find that their tongue or lips feel slightly irritated after eating a large amount of fresh pineapple.

Not everyone experiences this, and the effect varies from person to person.

🥫 Does Canned Pineapple Do the Same Thing?

Usually not to the same extent.

Canned pineapple is generally heat-treated, and heat can deactivate bromelain. That’s one reason some people notice a difference between eating fresh pineapple and canned pineapple.

Fresh pineapple has active enzymes, while processed pineapple may have much less enzymatic activity.
