In fact, most suppliers will do some of the work for you. Pineapple is almost always is cut from their plant while still green because they have a long way to travel before it sits on the shelf of your favorite grocery store. They are usually tested for ripeness, however, and all pineapple for sale should be ready and safe to eat, even if still green.
Many fruits produce ethylene gas, including bananas , apples , and pears. If pineapple is placed in a bag with any of these fruits it will start to turn from green to yellow, making it more appealing to buy. Once a pineapple is harvested, it will no longer get any sweeter.
But the texture, color, and aroma can be further developed, making the fruit more enjoyable, if not technically sweeter. As it ages, however, the texture will become softer and the color of the pineapple will go from green to yellow.
The most common way to ripen a pineapple, or any other unripe fruit for that matter, is to expose it to fruits that emit ethylene gas. You will need a large paper bag and a whole apple, pear, peach, or banana. These fruits produce an uncommonly high amount of ethylene gas, which is what will help your pineapple to ripen more quickly.
A pineapple that is artificially ripened like this can go from just right to overripe very quickly. To fix this, you simply want to ripen your fruit upside down. This may seem strange at first, but it makes sense for a few reasons.
First, having your pineapple upside-down also allows the natural sugars to flow more towards the crown, helping it to ripen faster.
It also prevents the sugars and juices from sinking to the bottom of the fruit, collecting and stagnating there until it spoils. You may want to use a sharp pair of kitchen scissors for this, and watch your hands carefully. As the fruit moves closer to harvest, the fruitlets begin to flatten and the outer skin of the pineapple begins to change from green to yellow. The ripening process starts at the bottom of the pineapple and slowly works its way up to the top. Pineapples are ripe and ready to harvest when the entire outer skin develops a yellowish color and a pineapple smell and the flesh is an orange-yellow color.
Each fully developed pineapple can weigh up to 5 pounds, but fruit grown from crowns is generally smaller than those found at your local market. If you harvest the pineapple before it totally changes colors, you can allow the outer skin to finish ripening indoors at room temperature. You can store ripe pineapples in the refrigerator for about a week before using.

Generally, it takes around 28 months for the pineapple to flower once planted; and another six months for its fruit to ripen. However, this can vary depending on certain factors, such as the temperature of the location and the type and size of the plant. Specifically, since pineapple is a tropical plant, it requires warmer temperatures to ripen, specifically between and degrees Fahrenheit.
Meanwhile, when it comes to the type and size of the plant used for propagation, recent studies have revealed that larger or heavier plants promise more vigorous growth than smaller or lighter ones. In fact, some pineapples are already ripe even if they are still partially covered in green.
Since this is the part that feeds sugar to the fruit, it must be from there that the pineapple changes color. Keep in mind that a fresh fruit presents a yellow coloration at the base of the fruit. But, a deteriorating pineapple presents a dark orange color. Another way you can determine whether a pineapple is ripe is by touching it and lightly squeezing the fruit.
As a general rule, if the pineapple feels slightly soft to the touch, this means you can pick the fruit. Simply flip the pineapple over and give its base a sniff. If you smell a sweet scent, this means that the pineapple is good to go.
However, if you can hardly smell a fruit scent at all, this likely means that the pineapple needs some time to reach its peak state. Has your pineapple already ripened? A yellow-skinned pineapple is a safer choice than a green one, but this isn't a perfect test. Some pineapples are ripe when completely green. Expect the pineapple to soften, but not sweeten. Pineapples do not ripen properly after they are picked. All of a pineapple's sugar comes from the starches in the stem of the plant.
Once that source is cut off, the pineapple cannot make more sugar on its own. It's possible that the pineapple will become even more acidic if stored too long. Prop it upside down optional. If the pineapple does have a little starch left to convert to sugar, this will be in the base of the fruit. In theory, the sugar might spread better if you keep the pineapple upside down. In practice, the effect is hard to notice, but it might be worth a try.
If it's difficult to prop up your pineapple, twist off the top and place the exposed end on a damp paper towel. Leave it at room temperature. The pineapple should soften within a day or two. Most pineapples will quickly ferment if stored for much longer than this. Keep reading to find out how to improve the taste of an unripe pineapple. If you're not ready to eat the pineapple yet, move it to the fridge for another 2—4 days. Part 2. Be cautious with unripe pineapples. Very young, unripe pineapples may be toxic.
Eating them can irritate your throat and have a severe laxative effect. Even ripe pineapple can hurt your mouth or cause it to bleed. The techniques below will help prevent this as well. Cut the pineapple. Cut off the stem and crown of the pineapple, then stand the rest flat on a cutting board. Cut off the rind and eyes, then slice into rounds or chunks. Grill the pineapple. Grilling will caramelize the sugars in the pineapple, adding flavor to a bland, partially unripe fruit.
Heat pineapple slices in the oven. This has the same results as grilling: a delicious, sweet pineapple. If the pineapple is quite tart and unripe, sprinkle brown sugar over it before heating. Simmer the pineapple. Although this won't caramelize the sugar, simmering will neutralize all of the bromelain. Try this if raw pineapple hurts your mouth: Add pineapple chunks to a saucepan along with all juice collected while cutting. Add enough water to cover. Bring to a boil over medium-high heat.
Reduce to a simmer and heat for 10 minutes. Drain and let cool. Sprinkle sugar over cut pineapple. If your pineapple doesn't taste sweet, sprinkle the chunks or rounds with sugar.
Eat right away, or store covered in the fridge.
