Mangoes are one of the most beloved and widely consumed fruits globally, renowned for their succulent texture, vibrant colors, and rich, sweet flavor. However, when it comes to harvesting mangoes, there’s a common dilemma many face: whether mangoes will ripen if picked green. This question is crucial not only for mango farmers but also for consumers who often find themselves with unripe mangoes. In this article, we’ll delve into the world of mango ripening, exploring the process, factors influencing ripeness, and most importantly, answering whether green-picked mangoes can indeed ripen.
Understanding Mango Ripening
Mango ripening is a complex process that involves a series of biochemical reactions. These reactions are triggered by the production of ethylene gas, a natural plant hormone that promotes ripening. When a mango is attached to the tree, it produces very little ethylene. However, as it matures and is picked, the ethylene production increases, initiating the ripening process. Temperature, humidity, and handling practices play significant roles in the ripening process, with optimal conditions accelerating the maturation of the fruit.
The Role of Ethylene in Ripening
Ethylene is the key driver of the ripening process in mangoes. As the fruit matures, the levels of ethylene gas it produces increase, stimulating a cascade of biochemical reactions. These reactions include the breakdown of starch into sugars, making the mango sweeter, the degradation of chlorophyll, which unmasks the natural pigments of the fruit, and the softening of the cell walls, which changes the texture of the mango from hard and green to soft and colorful. Understanding the role of ethylene is crucial for managing the ripening process, whether on the tree, in transit, or on the shelf.
Influence of Environmental Factors
Environmental factors such as temperature and humidity have a profound impact on the ripening of mangoes. Optimal temperatures for ripening mangoes range between 18°C to 22°C, with higher temperatures potentially leading to over-ripening and spoilage. Humidity levels should also be carefully controlled, as low humidity can cause the mangoes to dry out, while high humidity may foster the growth of mold and bacteria. Therefore, proper storage and handling conditions are essential for successfully ripening mangoes picked at any stage.
Ripening Green-Picked Mangoes
Now, addressing the core question: can mangoes ripen if picked green? The answer is yes, but with certain conditions and limitations. Mangoes, like many other fruits, continue to ripen after they’re picked due to the ongoing production of ethylene gas. However, the success of this process largely depends on the mango variety, the stage of maturity at the time of picking, and the post-harvest handling practices. Some mango varieties are more prone to successful ripening off the tree than others, and picking mangoes when they are mature but still green increases the chances of proper ripening after harvest.
Factors Influencing Successful Ripening
- Variety: Different mango varieties have varying potentials for post-harvest ripening. Some are bred for their ability to ripen well off the tree, making them ideal for export and distant markets.
- Maturity at Harvest: The stage of maturity at the time of picking is critical. Mangoes picked too early may not have the necessary starch reserves to convert into sugars during the ripening process, resulting in a less sweet and less flavorful fruit.
- Post-Harvest Care: How mangoes are handled, stored, and transported after picking significantly impacts their ability to ripen properly. Exposure to excessive heat, cold, or physical damage can impede the ripening process or lead to spoilage.
Techniques for Ripening Green Mangoes
Several techniques can be employed to encourage the ripening of green-picked mangoes. One common method involves placing the mangoes in a paper bag or a sealed container along with an apple or banana, as these fruits are known to produce ethylene gas, which can stimulate the ripening of the mangoes. Another technique involves storing the mangoes at room temperature, away from direct sunlight, until they begin to ripen, then moving them to the refrigerator to slow down the ripening process and prolong their freshness.
Best Practices for Mango Farmers and Consumers
For both mango farmers and consumers, understanding the ripening process and how to manage it can significantly improve the quality and longevity of the fruit. Farmers can adopt careful harvesting practices, picking mangoes at the optimal stage of maturity, and employ proper post-harvest handling techniques to ensure their produce reaches the market in the best possible condition. Consumers, on the other hand, can choose mangoes wisely, selecting those that are heavy for their size and have a sweet aroma, and store them appropriately to either hasten or delay ripening according to their needs.
Conclusion
In conclusion, mangoes can indeed ripen if picked green, provided they are harvested at the right stage of maturity and handled properly post-harvest. The key to successful ripening lies in understanding the biochemical processes involved, the influence of environmental factors, and the adoption of best practices in harvesting, storage, and transportation. By grasping these principles, both mango farmers and consumers can enjoy high-quality, ripe mangoes throughout the year, appreciating the full depth of flavor and texture this magnificent fruit has to offer.

Whether you’re a seasoned mango enthusiast or just discovering the delight of this tropical fruit, recognizing the potential for green-picked mangoes to ripen offers a world of culinary possibilities and appreciate the science behind the ripening process.
Will Mangoes Ripen if Picked Green?
Mangoes picked at the green stage can indeed ripen, but the process and outcome might vary depending on several factors, including the mango variety, the stage of greenness when picked, and how they are subsequently handled and stored. Some mango varieties are bred to ripen better off the tree than others, so understanding the specific type of mango is crucial. Generally, mangoes that are picked when they have reached physiological maturity but are still green will ripen. This is because they have already developed the necessary sugars and acids that will convert to more sugars as they ripen, giving them their characteristic sweetness and flavor.
The ripening process for green mangoes involves a series of biochemical reactions that are triggered once the fruit is detached from the tree. Ethylene production, a natural ripening hormone, plays a significant role in this process. Mangoes, like many other fruits, produce ethylene gas as they ripen, which in turn accelerates the ripening process. Proper storage conditions, such as maintaining a warm temperature and humidity level, can enhance ethylene production and help green mangoes ripen evenly. However, if mangoes are picked too early in their development, they may not ripen properly even under the best conditions, as they may not have accumulated enough starches to convert into sugars during the ripening process.
How Long Does it Take for Green Mangoes to Ripen?
The time it takes for green mangoes to ripen can vary significantly based on factors like the variety of mango, the stage of ripeness when picked, storage conditions, and handling practices. Generally, under optimal conditions, green mangoes can start showing signs of ripening within 3 to 8 days, with some varieties taking longer. The ripening process can be influenced by factors such as temperature (with warmer temperatures speeding up the process but risking spoilage if too high), humidity, and ethylene exposure.
Optimal storage conditions for ripening green mangoes typically include temperatures between 65°F and 75°F (18°C and 24°C), with moderate humidity. It’s also advisable to avoid refrigerating green mangoes until they have fully ripened, as cold temperatures can slow down the ripening process or even stop it altogether. As mangoes ripen, they will become softer to the touch, develop a sweet aroma, and change in skin color, turning from green to various hues of yellow, orange, red, or any combination thereof, depending on the variety. Checking on them regularly can help ensure they are consumed at the peak of ripeness.
Can You Ripen Mangoes at Home?
Yes, you can ripen mangoes at home, provided you have mangoes that were picked at the right stage of maturity. The process involves creating an environment that mimics the conditions necessary for natural ripening. One common method is to place the mangoes in a paper bag, as this traps ethylene gas and helps to speed up the ripening process. Adding an apple or banana to the bag can further enhance this effect, as these fruits are known to produce a significant amount of ethylene.
To ripen mangoes effectively at home, it’s essential to monitor their progress regularly. Mangoes that are too green and not yet mature enough for ripening might not respond well to these methods, emphasizing the importance of starting with the right fruit. Additionally, once mangoes begin to ripen, they can quickly become overripe and spoil. Therefore, storing them at room temperature until they begin to ripen and then transferring them to the refrigerator to slow down the ripening process can help extend their freshness and quality. This way, mangoes can be enjoyed over a longer period.
What Are the Best Conditions for Mango Ripening?
The best conditions for mango ripening involve a combination of optimal temperature, humidity, and ethylene exposure. Temperature is critical, with most mango varieties ripening best between 65°F and 75°F (18°C and 24°C). Higher temperatures can speed up the process but also increase the risk of spoilage or the development of off-flavors. Humidity levels should also be moderate, as very dry conditions can prevent the mango from ripening evenly, while overly humid conditions can lead to mold and rot.
Ethylene exposure is another crucial factor in mango ripening. This gas naturally promotes ripening in fruit. Methods to enhance ethylene production and exposure, such as storing mangoes with other ethylene-producing fruits like apples or bananas, can help speed up the ripening process. However, it’s also important to avoid exposing mangoes to direct sunlight and extreme temperatures, as these can cause uneven ripening or damage to the fruit. By managing these conditions, individuals can effectively ripen mangoes and enjoy them at their best flavor and texture.
How Can I Tell if a Green Mango is Ripe Enough to Ripen at Home?
Determining if a green mango is ripe enough to ripen at home involves checking for signs of maturity. One of the primary indicators is the mango’s weight; generally, heavier mangoes for their size are closer to being ripe. The skin color and texture can also provide clues, with ripe mangoes typically having a slight yellow or pink tint around the stem and being slightly soft to the touch, though still firm. The stem end of the mango should come off easily, indicating it is ready or nearly ready to ripen.
Checking the mango’s “shoulders” (the area around the stem) for a slight softening can also help determine its readiness to ripen. A mild, fruity aroma is another indicator that the mango is nearing ripeness. However, these signs can be subtle, and the best way to ensure a mango will ripen is to purchase from a reputable supplier who can provide information on the mango variety and its maturity stage. If possible, asking the seller about the mango’s ripening potential or purchasing mangoes that are already starting to show signs of ripening can increase the chances of successfully ripening them at home.
Can All Mango Varieties Ripen Off the Tree?
Not all mango varieties are created equal when it comes to their ability to ripen off the tree. Some mangoes are bred specifically for their ability to ripen well after being picked, while others may not ripen as evenly or may require specific conditions to do so. Understanding the specific variety of mango is crucial in determining its potential for ripening off the tree. Varieties like ‘Tommy Atkins’, ‘Ataulfo’, and ‘Haden’ are known for their good off-tree ripening characteristics, making them popular choices for both growers and consumers.
The genetic predisposition of a mango variety to produce ethylene and respond to it with ripening is a key factor in its ability to ripen off the tree. Furthermore, the stage of maturity at harvest also plays a significant role; mangoes picked too early might not have developed enough to ripen properly, even with optimal conditions. Farmers and distributors often have knowledge about the specific ripening characteristics of different mango varieties, which can help consumers make informed choices when purchasing green mangoes with the intention of ripening them at home. This knowledge can significantly enhance the success rate of ripening mangoes off the tree.
