Mangoes are one of the most delicious and nutritious fruits in the world, but their short shelf life can be a major drawback. Whether you’re a mango enthusiast, a chef, or a homeowner with a mango tree, preserving mangoes is essential to enjoy them throughout the year. In this article, we’ll explore the best ways to preserve mangoes, from traditional methods to modern techniques.
Understanding Mango Preservation
Before we dive into the preservation methods, it’s essential to understand the factors that affect mango spoilage. Mangoes are a tropical fruit that’s high in water content and has a soft, delicate skin. These characteristics make them prone to spoilage, especially when exposed to heat, moisture, and oxygen.
The Science of Mango Spoilage
Mango spoilage occurs due to the breakdown of cellular tissues, which leads to the production of ethylene gas. Ethylene gas is a natural plant hormone that promotes ripening and senescence (aging). When mangoes are injured or infected, the production of ethylene gas increases, causing the fruit to ripen and spoil faster.
Factors Affecting Mango Spoilage
Several factors contribute to mango spoilage, including:
- Temperature: High temperatures (above 25°C/77°F) accelerate mango spoilage.
- Humidity: High humidity (above 80%) promotes moisture accumulation, leading to spoilage.
- Oxygen: Exposure to oxygen can cause mangoes to ripen and spoil faster.
- Physical damage: Injuries or bruises can increase ethylene production, leading to spoilage.
- Microbial contamination: Bacteria, yeast, and mold can infect mangoes, causing spoilage.
Traditional Methods of Mango Preservation
For centuries, people have used various traditional methods to preserve mangoes. These methods are simple, cost-effective, and often rely on natural ingredients.
Drying Mangoes
Drying is one of the oldest methods of preserving mangoes. By removing the water content, you can prevent the growth of microorganisms and extend the shelf life of mangoes. There are several ways to dry mangoes, including:
- Sun drying: Slice mangoes thinly and dry them in the sun, either by placing them on a wire rack or by hanging them from a tree.
- Smoking: Smoke mango slices over low heat to dry them out.
- Dehydrating: Use a food dehydrator or a low-temperature oven (150°F/65°C) to dry mango slices.
Benefits of Dried Mangoes
Dried mangoes are a healthy snack, rich in fiber, vitamins, and minerals. They can be stored for up to 6 months and can be rehydrated by soaking them in water or a flavorful liquid.
Pickling Mangoes
Pickling is another popular method of preserving mangoes. By soaking mango slices in a brine solution (water, salt, and spices), you can create a tangy, sour snack that’s rich in probiotics.
Benefits of Pickled Mangoes
Pickled mangoes are a great way to enjoy mangoes throughout the year. They’re rich in vitamins, minerals, and antioxidants, and can be stored for up to 6 months in the refrigerator.

What are the different methods of preserving mangoes?
There are several methods of preserving mangoes, including canning, freezing, dehydrating, pickling, and jam-making. Each method has its own unique benefits and drawbacks, and the best method for you will depend on your personal preferences and the equipment you have available. Canning and freezing are great ways to preserve mangoes for long-term storage, while dehydrating and pickling are better suited for shorter-term preservation.
When choosing a preservation method, it’s also important to consider the ripeness and variety of the mangoes. For example, some varieties of mangoes are better suited for canning, while others are better for freezing. Additionally, mangoes that are too ripe may not hold up well to certain preservation methods, so it’s best to use them for jam-making or other recipes where texture isn’t as important.
How do I can mangoes at home?
Canning mangoes at home is a relatively simple process that requires some basic equipment and attention to detail. To start, you’ll need a large pot, a canning rack, and some glass jars with lids and bands. You’ll also need a pressure canner, as mangoes are a low-acid fruit and require high heat to kill off any bacteria. Begin by preparing your mangoes by washing, peeling, and chopping them into small pieces.
Next, pack the mango pieces into the jars, leaving about 1/2 inch of headspace at the top. Add a syrup made from sugar and water, and then process the jars in the pressure canner for 10-15 minutes. Remove the jars from the canner and let them cool, then store them in a cool, dark place. It’s also important to follow safe canning practices to ensure that your mangoes are properly sterilized and sealed.
Can I freeze mangoes whole?
While it is technically possible to freeze mangoes whole, it’s not the most recommended method. Freezing mangoes whole can cause them to become mushy and unappetizing, as the water inside the fruit expands and breaks down the cell walls. Instead, it’s better to chop or puree the mangoes before freezing them. This will help to preserve their texture and make them easier to use in recipes.
To freeze mangoes, simply chop or puree them and place them in an airtight container or freezer bag. Label the container or bag with the date and contents, and then store it in the freezer. Frozen mangoes are perfect for using in smoothies, baked goods, and other recipes where texture isn’t as important.
How do I dehydrate mangoes at home?
Dehydrating mangoes at home is a simple and healthy way to preserve them. To start, you’ll need a dehydrator or your oven on the lowest temperature setting. Slice the mangoes thinly and place them in a single layer on the dehydrator trays or a baking sheet. Dehydrate the mangoes for 6-8 hours, or until they reach your desired level of dryness.
Once the mangoes are dehydrated, you can store them in an airtight container for up to 6 months. Dehydrated mangoes are perfect for snacking on the go, adding to trail mix, or using in recipes. You can also rehydrate them by soaking them in water or another liquid.
Can I make jam with unripe mangoes?
While it is technically possible to make jam with unripe mangoes, it’s not the most recommended method. Unripe mangoes are often too tart and fibrous to make good jam, and they may not have the same level of sweetness and flavor as ripe mangoes. Instead, it’s better to use ripe or slightly overripe mangoes for jam-making.
To make jam with mangoes, simply chop them up and combine them with sugar and pectin (optional) in a large pot. Bring the mixture to a boil, then reduce the heat and simmer until the jam has thickened. You can also add other ingredients, such as spices or citrus juice, to give the jam more flavor.
How do I store preserved mangoes?
The storage method for preserved mangoes will depend on the preservation method used. Canned mangoes should be stored in a cool, dark place, such as a pantry or cupboard. Frozen mangoes should be stored in the freezer, while dehydrated mangoes can be stored in an airtight container at room temperature. Jam and pickled mangoes should be stored in the refrigerator.
Regardless of the preservation method, it’s also important to check on the mangoes regularly to ensure that they are still safe to eat. Look for signs of spoilage, such as mold or an off smell, and discard any mangoes that are past their prime.
Are preserved mangoes nutritious?
Preserved mangoes can be a nutritious and healthy addition to your diet, depending on the preservation method used. Canned and frozen mangoes are often high in vitamin C and fiber, while dehydrated mangoes are a good source of antioxidants. Jam and pickled mangoes may be higher in sugar and salt, but they can still be a healthy choice in moderation.
To get the most nutritional benefits from preserved mangoes, choose methods that minimize added sugars and salt. You can also add other ingredients, such as spices or citrus juice, to give the mangoes more flavor without adding extra sugar or salt.
