Mangoes are one of the most delicious and nutritious fruits available, but they can be quite finicky when it comes to handling and storage. One of the most common issues people face when dealing with mangoes is the discoloration that occurs after cutting them. But does mango really turn brown after you cut it? In this article, we’ll delve into the science behind this phenomenon and explore ways to prevent or minimize browning.
Understanding the Science Behind Browning
Browning in mangoes is a result of an enzymatic reaction that occurs when the fruit is injured or cut. This reaction is triggered by the release of an enzyme called polyphenol oxidase (PPO), which is naturally present in the fruit. PPO reacts with oxygen in the air to form quinones, which are brown pigments that cause the fruit to discolor.
The Role of Enzymes in Browning
Enzymes play a crucial role in the browning process. PPO is the primary enzyme responsible for browning in mangoes, but other enzymes like peroxidase and lipoxygenase can also contribute to the reaction. These enzymes are present in the fruit’s cells and are released when the cells are damaged or cut.
Factors That Influence Browning
Several factors can influence the rate and extent of browning in mangoes. These include:
- Temperature: Higher temperatures can accelerate the browning reaction.
- Oxygen levels: Increased oxygen levels can enhance the browning reaction.
- pH levels: A higher pH level can slow down the browning reaction.
- Enzyme concentration: Higher enzyme concentrations can lead to faster browning.
Preventing or Minimizing Browning
While it’s impossible to completely prevent browning, there are several ways to minimize or slow down the reaction. Here are some methods you can try:
Using Acidic Substances
Applying acidic substances like lemon juice or vinegar can help slow down the browning reaction. The acidity helps to denature the enzymes and reduce the pH level, making it less favorable for the browning reaction to occur.
Other Methods
Other methods that can help prevent or minimize browning include:
- Using ascorbic acid: Ascorbic acid, also known as vitamin C, is a natural antioxidant that can help prevent browning.
- Applying heat: Briefly heating the mango can help inactivate the enzymes and slow down the browning reaction.
- Using modified atmosphere packaging: Packaging the mango in a modified atmosphere with reduced oxygen levels can help slow down the browning reaction.
Practical Tips for Handling Mangoes
Here are some practical tips for handling mangoes to minimize browning:
- Handle mangoes gently: Avoid bruising or damaging the fruit, as this can trigger the browning reaction.
- Store mangoes properly: Store mangoes in a cool, dry place, away from direct sunlight.
- Use the right cutting tools: Use a sharp knife to cut the mango, as a dull knife can cause more damage and trigger the browning reaction.
Cutting and Preparing Mangoes
When cutting and preparing mangoes, it’s essential to minimize the amount of time the fruit is exposed to oxygen. Here are some tips:
- Cut the mango just before serving: Cutting the mango just before serving can help minimize the browning reaction.
- Use a fruit preserver: Applying a fruit preserver, such as Fruit Fresh, can help prevent browning.
Conclusion
In conclusion, mangoes do turn brown after you cut them, but there are ways to prevent or minimize the browning reaction. By understanding the science behind browning and using the right techniques, you can enjoy your mangoes for a longer period. Whether you’re a mango enthusiast or just a casual fruit lover, these tips can help you appreciate the delicious taste and nutritional benefits of mangoes.

What causes mango to turn brown after cutting?
Mango, like many other fruits, contains an enzyme called polyphenol oxidase (PPO). This enzyme reacts with oxygen in the air to produce a brown pigment called melanin, which is responsible for the browning of the fruit. When a mango is cut, the cells are damaged, releasing the PPO enzyme and allowing it to react with oxygen, resulting in the formation of melanin and the subsequent browning of the fruit.
The browning reaction can be accelerated by factors such as heat, light, and oxygen exposure. Therefore, it’s essential to minimize the exposure of cut mango to these factors to slow down the browning process. This can be achieved by storing the cut mango in an airtight container, keeping it refrigerated, and using acidic ingredients like lemon juice to slow down the browning reaction.
How can I prevent mango from turning brown after cutting?
To prevent mango from turning brown after cutting, you can use a combination of methods. One way is to sprinkle the cut mango with lemon juice or vinegar, which will help to slow down the browning reaction. You can also try using ascorbic acid, a natural antioxidant that can be found in many fruits and vegetables. Additionally, you can store the cut mango in an airtight container and keep it refrigerated to minimize exposure to oxygen and heat.
Another method is to use a commercial anti-browning agent, such as Fruit Fresh or Browning Inhibitor. These products contain ingredients that can help to slow down the browning reaction and keep the mango fresh for a longer period. You can also try using a combination of these methods to achieve the best results.
Does the variety of mango affect its tendency to turn brown?
Yes, the variety of mango can affect its tendency to turn brown. Some mango varieties, such as the Tommy Atkins and Kent, are more prone to browning due to their higher PPO enzyme activity. On the other hand, varieties like the Ataulfo and Haden tend to have lower PPO activity and are less likely to turn brown.
The ripeness of the mango can also play a role in its tendency to turn brown. Mangoes that are overripe or underripe may be more prone to browning due to their higher PPO activity. Therefore, it’s essential to choose mangoes that are ripe but still firm to minimize the risk of browning.
Can I use mango that has turned brown?
While mango that has turned brown may not be visually appealing, it can still be safe to eat and use in recipes. However, it’s essential to check the mango for any signs of spoilage, such as an off smell or slimy texture. If the mango has turned brown due to oxidation, it may still be usable, but if it has turned brown due to spoilage, it’s best to err on the side of caution and discard it.
If you decide to use mango that has turned brown, make sure to use it immediately, as it can continue to deteriorate quickly. You can also try to salvage the mango by using it in cooked recipes, such as smoothies or baked goods, where the browning won’t be as noticeable.
How can I store cut mango to keep it fresh?
To store cut mango and keep it fresh, it’s essential to minimize its exposure to oxygen, heat, and light. You can store the cut mango in an airtight container, such as a glass or plastic container with a tight-fitting lid. Make sure to press plastic wrap or aluminum foil directly onto the surface of the mango to prevent air from reaching it.
You can also store the cut mango in the refrigerator to keep it cool and slow down the browning reaction. Make sure to keep the mango away from strong-smelling foods, as it can absorb odors easily. If you won’t be using the cut mango within a day or two, you can also consider freezing it to preserve its freshness and texture.
Can I freeze mango to prevent browning?
Yes, you can freeze mango to prevent browning. Freezing will help to inactivate the PPO enzyme and prevent the browning reaction. To freeze mango, make sure to cut it into small pieces or slices and store it in an airtight container or freezer bag. You can also add a splash of lemon juice or ascorbic acid to the mango before freezing to help preserve its color and texture.
When you’re ready to use the frozen mango, simply thaw it in the refrigerator or at room temperature. Keep in mind that frozen mango may be softer and more prone to browning than fresh mango, so it’s best to use it in cooked recipes or smoothies where texture isn’t a concern.
Are there any health risks associated with eating brown mango?
In general, eating brown mango is not a significant health risk, as long as the mango is not spoiled or contaminated. However, it’s essential to check the mango for any signs of spoilage, such as an off smell or slimy texture, before consuming it. If the mango has turned brown due to oxidation, it may still be safe to eat, but if it has turned brown due to spoilage, it’s best to err on the side of caution and discard it.
It’s also worth noting that brown mango may have a lower nutritional value than fresh mango, as the browning reaction can break down some of the fruit’s natural antioxidants and vitamins. However, the nutritional impact of eating brown mango is likely to be minimal, and it can still be a healthy and delicious addition to a balanced diet.
