Did You Know?
1. The sweet potato is not actually a potato, but belongs to the morning glory family, along with its distant cousins, bindweed and moonflower.
2. Contrary to popular belief, the sweet potato is native to Central and South America, not to Ireland where it is often associated with.
3. Sweet potatoes have a remarkably long shelf life, with some varieties able to last up to a year when stored properly in a cool and dry environment.
4. The consumption of sweet potatoes dates back over 5,000 years, as evidence of its cultivation has been found in ancient Peruvian caves.
5. Sweet potatoes are packed with essential nutrients such as fiber, vitamin A, and potassium, which make them a healthier alternative to regular potatoes when it comes to overall nutritional value.
The Importance Of Curing Sweet Potatoes
Sweet potatoes are a popular and versatile vegetable enjoyed by many people worldwide. After harvesting, curing is necessary to promote healing, protect against storage diseases, and increase post-harvest life.
Curing is a process that involves maintaining specific temperature and humidity conditions to ensure optimal preservation of sweet potatoes. One significant benefit of curing is promoting healing for any cuts or bruises that may have occurred during harvesting. Since sweet potatoes are prone to physical damage, providing a favorable environment for healing reduces the risk of further deterioration.
Besides healing, curing protects sweet potatoes against storage diseases. By subjecting them to specific temperature and humidity conditions, the growth of pathogens that cause diseases is suppressed. This preventive measure ensures sweet potatoes remain healthy and safe for consumption during storage.
Additionally, curing plays a vital role in enhancing the flavor of sweet potatoes. During this process, the conversion of starches to sugars and flavor components takes place. This natural conversion process not only improves the taste of sweet potatoes but also makes them more enjoyable for consumers.
Curing Conditions For Sweet Potatoes
To achieve effective curing, it is necessary to provide the appropriate conditions for sweet potatoes. The ideal temperature for curing sweet potatoes is around 85 degrees Fahrenheit (29 degrees Celsius), while the relative humidity should be maintained at 90-95%. These specific conditions create a favorable environment that supports the healing and flavor development processes.
Curing typically lasts for a period of 4-7 days. It is essential to closely monitor the temperature and humidity levels during this time to ensure optimal results. Proper ventilation is also crucial to prevent any moisture buildup that could lead to rotting or fungal growth.
Recommended Storage Conditions After Curing
Once the sweet potatoes have been properly cured, it is important to adjust the storage conditions to maintain their quality and extend their post-harvest life. After curing, it is recommended to reduce the storage temperature to around 55-60 degrees Fahrenheit (13-16 degrees Celsius). At the same time, the relative humidity should be maintained at 80-85%.
These lower temperature and humidity levels help to slow down the sweet potatoes’ natural aging process without causing chilling injury. Chilling injury can occur if sweet potatoes are stored below 54 degrees Fahrenheit (12 degrees Celsius). On the other hand, temperatures above 60 degrees Fahrenheit (16 degrees Celsius) can stimulate sprout development and result in pithiness and internal cork, especially when the virus is present.
- Adjust storage temperature to 55-60 degrees Fahrenheit (13-16 degrees Celsius)
- Maintain relative humidity at 80-85%

Shelf Life Of Properly Cured Sweet Potatoes
Most sweet potato cultivars that have been properly cured can be stored for 4-7 months. However, it is important to note that the shelf life can vary depending on the specific cultivar and storage conditions. Changes in temperature and relative humidity can significantly affect the sweet potatoes’ longevity.
For prolonged storage, it is crucial to regularly monitor the storage environment and maintain the recommended temperature and humidity levels. This will help to minimize the risk of spoilage and preserve the sweet potatoes’ quality for an extended period.

Storage Methods For Sweet Potatoes
Sweet potatoes are typically stored in bulk bins or slatted crates. These containers provide good ventilation and allow air circulation around the sweet potatoes, which is important for maintaining their freshness. Palletization and the use of pallet boxes also facilitate the handling and transport of sweet potatoes.
It is important to keep in mind that the roots of sweet potatoes are alive and require sufficient oxygen to survive, even during storage. Therefore, adequate airflow and ventilation are essential to ensure their vitality. Nonrefrigerated commercial or farm warehouses are commonly used for sweet potato storage, as they provide the necessary storage conditions and space required for bulk storage.
the curing process is of utmost importance when it comes to sweet potato storage. It promotes healing, protects against storage diseases, and enhances the flavor of these delicious root vegetables. By following the recommended curing conditions and adjusting the storage conditions accordingly, sweet potatoes can be stored for an extended period, allowing consumers to enjoy their nutritious and versatile qualities throughout the year.

Frequently Asked Questions
What is the easiest way to cure sweet potatoes?
The easiest way to cure sweet potatoes is by utilizing empty greenhouses during this time of year, as they provide ideal conditions for the process. However, there are a few necessary steps to be taken. First, the temperature inside the greenhouse should be maintained at around 85°F, and the humidity levels should be kept at 90%. These conditions should be maintained for a period of 5-7 days to ensure proper curing of the sweet potatoes. By following these steps, sweet potatoes can be efficiently cured in the greenhouse, making it the easiest method for this process.
How do you cure potatoes?
To cure potatoes, place them in a cool area with a temperature ranging from 45 to 60 degrees Fahrenheit and ensure the relative humidity levels are between 85 to 95 percent for a period of approximately two weeks. This curing process allows the potatoes to heal minor cuts and bruises while the skin thickens. After the curing period, carefully sort through the potatoes, discarding any tubers that appear soft, shriveled, or blemished. The result will be wholesome and quality potatoes ready for consumption or storage.
What is the treatment of sweet potatoes?
To enhance the quality of sweet potatoes, it is essential to implement a treatment process known as curing. By providing optimal conditions such as warmth and humidity, sweet potatoes can be cured for a period of 4 to 14 days. During this time, the starches within the potatoes undergo a transformation into sugars, promoting a sweeter taste. Additionally, any cuts or damages on the potato’s surface heal, while the skins thicken to improve moisture retention.
What methods are used to preserve sweet potatoes?
To preserve sweet potatoes, it is important to store them properly. Raw sweet potatoes should be kept in a cool, dry, and dark place, without any wrapping, for a maximum of two months. Alternatively, they can be stored at room temperature for up to a week. This allows them to retain their freshness and prevent spoiled or moldy spots. On the other hand, cooked sweet potatoes can be preserved by refrigerating them, freezing them, drying them, or canning them. These methods help extend their shelf life, ensuring that they can be enjoyed at a later time while still maintaining their flavor and nutritional value.
