How To Store Mangosteens

At room temperature, ripe mangosteens should be stored where it’s cool and dry. The cooler the place of storage the longer they will last. Good location for storing mangosteens are the pantry and cupboards.

If the fruit is going to be eaten within a day, storing them on the countertop or anywhere in the kitchen should be fine. Make sure to keep them away from direct sunlight and other heat sources. The heat will harden the rind of the fruit and cook the inside of it. What you’ll get is a watery and mushy flesh that will taste bad.

In the fridge, ripe mangosteens should be stored in a plastic bag or an airtight container. The thick rind on the mangosteens will help prevent the fruit from going bad, while the plastic bag or container will help retain their moisture.

As for unripe mangosteens, at room temperature, the fruit should be stored in a cool and dry place. Avoid storing them in direct sunlight and near any other heat source. The heat can actually cause the fruit to prematurely ripen and make the fruit uneatable.

If you need to ripen the mangosteen faster, simply put them in a paper brown bag along with an apple, bananas, pears, or even an avocado. These fruits contain ethylene which will accelerate the ripening process of the mangosteen. Depending on how unripe the mangosteen is, it can ripen overnight or in a day or so.

As for the fridge, it’s not recommended to store unripe mangosteens. Storing them in the fridge could prematurely ripen the fruit. While the fruit is being stored in the fridge, the cool temperature will prevent it from ripening normally. When this happens, the fruit won’t be able to develop the sweet and sour taste.

How To Keep Mangosteens Fresh Longer

Buying Mangosteens

At the grocery store, always buy quality mangosteens which will ensure they stay fresh for a long time. Before buying this delicious fruit, there are some signs to look for. Unlike other fruits, mangosteen is a bit tricky to tell bad ones from the good ones.

One of the signs to look for is the tears and cuts on the rind. Sure, the fruit has a thick rind that’s difficult to break open, but it can break open during harvesting and being transported to the grocery stores. If the fruit has a crack in the rind, the flesh is exposed to the air. This will cause the fruit to prematurely go bad due to oxidation and bacterial growth.

Another sign to look for is the hardness of the fruit. If the fruit is hard, it could mean the mangosteen is either unripe or it has gone bad. One way to tell them apart is to pick one up and see if it’s light or heavy in weight. Unripe mangosteens will have some weight to them. Mangosteens that is spoiled will be light like nothing is inside of it.

Therefore, you should buy the one that has a hard rind with some weight to it.

If the mangosteen has a soft rind when you apply gentle pressure to it, it means the fruit is ripe. These are good quality fruit, but make sure there are no cuts or tears in the rind before buying them.


How To Tell When Mangosteens Is Bad

When mangosteens go bad or are bad, there are a couple of signs to look for. Just because they have signs of going bad doesn’t necessarily mean the fruit can’t be eaten.

Appearance – The rind of the mangosteen is a little tricky when it comes to telling them apart from unripe and bad fruit. Unripe and bad mangosteens will have a very hard rind. Therefore, you should know when the fruit was harvested. If it’s was just bought from the store and the rind is hard, more than likely, it’s not ripe yet.

If you already know the mangosteen has ripened already, if the rind is very hard when you squeeze it, that means the fruit is bad.

Color and Texture – The flesh of the mangosteens should be white color all over and have a firm texture. As it goes bad, the color will start to darken and become almost translucent. The texture of the flesh will begin to be soft and mushy as the color of the flesh begins to darken. If you notice this, the fruit is starting to go bad.

If the color darkens in a couple of places along with mushy flesh, it’s still safe to eat it though. Simply remove the darkened area and eat the rest of the fruit.

However, if the entire flesh darkens and have mushy textures, it’s best to throw it away.

Taste – Bad mangosteens will have a fermented and sour taste to it. Hopefully, you’ll never need to taste it as the appearance of the flesh will prevent you from going any further with the fruit.
