How To Tell If Coconut Is Bad – The Ultimate Guide

For a long time, coconut water has become a perfect refreshment during the summer months. Many people keep coconuts in their house to take a sip anytime they feel thirsty or tired.

Therefore, they are most interested in learning how to tell if coconut is bad or should coconut be refrigerated to ensure health safety. If you are in the same boat, then check out this post now.

Can Coconut Go Bad?

Can Coconut Go Bad

Yes. The truth is, coconuts will spoil pretty quickly once they’re opened because they have an enzyme called polyphenol oxidase (PPO), which is the substance that causes the browning in fruits when they begin to rot.

And does shredded coconut go bad?

They can go bad, too. There are numerous causes for this, including improper temperature, humidity, microbial invasion, and many others.

However, do not worry too much because there will be signs for you to notice and avoid consuming rancid coconut. Some of them are purple coconut meat and brown coconut water.

How Long Do Coconuts Last?

In comparison to most other fruits, coconut lasts the longest. Because of the relatively thick shell and strong fibrous layer inside, it will be difficult for bacteria or insects to penetrate and destroy the coconut water.

But to be more specific,  how long are coconuts good for? Here’s our answer:

We can keep natural coconut for around seven days and still retain its original flavor without any preservation at room temperature. However, to ensure the sweetest taste, deliciousness, and nutrition of coconut water, drink it immediately after purchasing it.

But, in reality, few individuals buy agricultural products and keep them in their kitchens for a week. Even youngsters have a habit of putting food in the refrigerator when it is not in use.

Indeed, the best advice on how to keep coconut fresh is to put it in the fridge. Most households use refrigeration to extend the fresh coconut shelf life by up to three weeks. Regular residential refrigerators have a cooler compartment temperature of about 3-4 degrees Celsius, and the freezer temperature can range from 0 to lower.

This is an excellent habitat for regulating the growth of bacteria, which are the primary source of food rancidity. Furthermore, today’s modern technologies with germicidal ions can help the inside of a coconut stay fresh for longer and retain coconut taste.

How To Tell If Coconut Is Bad?

We will show you 3 straightforward ways to tell the difference between a fresh and a spoiled coconut. These steps are more like how to pick a good coconut. Follow this guide, and you’re good to go.

Check The Coconut Eyes

Keep an eye on this point and pay special attention to it.

Each coconut will have three little holes placed in a triangle form on its surface. Long-time growers or traders will usually refer to them as coconut eyes. This is the most evident sign of the current state of the coconut, and it will tell you if the coconut gone bad or not.

If you closely examine and notice any leaking places of yellow coconut water or coconut mold around the eyes, then it is very likely that your coconut has been severely damaged.

Furthermore, coconut eyes and stalks have been infused with substances to fool your taste buds, frequently foaming. This is also an important issue to consider when deciding to purchase an item.

However, many sellers will put it in the refrigerator after injecting, where the coconut stem will return to its normal state. In this case, proceed with the steps below on how to tell if a coconut is spoiled.

Hear The Sound

If you still can’t tell the difference or are still in doubt, you can tap the coconut with your fingertips or shake it well. 

The optimum sound would be similar to shaking a pitcher filled with around half the amount of water. It will oscillate and collide with the wall, emitting a loud, clear sound.

The reason for this is the amount of water in the coconut will decrease as it grows. At perfect ripeness, only about half of the quality juice is left. Thereby, creating a bass sound that is nice to hear.

Open Up The Coconut

Open up the coconut

Young coconut has soft skin with bright green color, and the copra is soft. Besides, you can find young coconuts by pressing your fingernails into the copra; the coconut milk will have a characteristic aromatic flavor.

On the other hand, spoiled coconut water has a bad smell, with a bit sour like sour buttermilk. Some people even rate bad coconut tastes like soap. What a bad experience if you decide to serve this to anyone!

Housewives must also pay attention to the color of the copra once the coconut opened. The copra and its inner surface should be white, neither transparent nor slightly opaque or ivory, and the outer shell should be light brown.

What Does A Bad Coconut Taste Like?

Many people believe that the longer a coconut sits and ages on the palm, the stronger and sweeter its flavor becomes. However, too much is not beneficial, and as previously stated, the coconut might go rotten.

And once that happens, it is more likely that bad coconut water tastes sour and smelly due to the growth of mold and microorganisms inside. Not only that, but as soon as you crack the coconut in half, you can smell the musty odor, which is not at all pleasant.

What Are The Health Benefits Of Coconuts?

The most popular nutritional product from coconut is probably coconut water, with its natural sweetness and freshness. It includes sugars and electrolytes with easily digestible carbs.

Low-calorie content, naturally free of fat and cholesterol, high in potassium are some of the numerous documented benefits of coconut water.

Besides, fresh coconut water is rich in potassium and other minerals, so it can help you regulate the fluid inside the body. The electrolyte and plasma balance in coconut water is quite similar to that of human blood. Therefore, for adults and kids seeking a less sweet drink, pure coconut water could be a preferable choice.

Drinking coconut water can help reduce the risk of cardiovascular disease due to its ability to lower harmful cholesterol and fight free radicals in the body.

Furthermore, it is such a mistake to overlook the antioxidant power, which aids in improving the skin and the appearance of youth. Overall, this is a refreshing drink that is beneficial to your health.

How To Store Coconut Properly?

To best keep fresh coconuts for the family, you should put the whole coconut intact in the refrigerator compartment, with no openings. This method of storing coconuts preserves the natural protective covering while also preventing microorganisms from entering.

However, if you buy cracked coconuts at the supermarket, you should separate the water and the copra. Keep coconut water in an airtight container, such as a large mason jar. This way, the coconut water retains all of its sweetness as well as its benefits.

Regarding the copra, we recommend wrapping it in cling film and storing it in the refrigerator. However, this will not be available for long, so please utilize them as soon as possible.
