Storing steamed sweet potatoes in the freezer creates an environment unsuitable for bacterial growth. Additionally, the freezer itself has low bacterial content, allowing for storage up to one month.
How long can steamed sweet potatoes be stored in the refrigerator?
Steamed sweet potatoes can be kept in the refrigerator for 3 to 5 days.
Although the refrigerator contains fewer bacteria than the outside environment, some bacteria are still present. Therefore, it's best to consume steamed sweet potatoes stored in the refrigerator within 3 to 5 days to avoid spoilage from prolonged storage.
How to consume refrigerated steamed sweet potatoes
1. For sweet potatoes stored in the freezer, transfer them to the refrigerator the day before consumption to thaw.
2. Sweet potatoes thawed in the refrigerator compartment or stored directly in the refrigerator should be steamed again before consumption. Steam them for about 10 minutes using a rice cooker or pressure cooker to sterilize them and remove the cold air from the refrigerator.
Who should avoid eating refrigerated cooked sweet potatoes?
Individuals with digestive disorders
Those with poor digestion should avoid refrigerated cooked sweet potatoes. Starch that has been heated and gelatinized can retrogradate at low temperatures, becoming harder to digest. For people with digestive issues, consuming it may increase digestive difficulty and cause discomfort.
Elderly and children
The elderly often have weaker teeth and reduced digestive capacity, while children's digestive systems are still developing. Consuming retrograded starch may cause discomfort in both groups.
Precautions for Eating Refrigerated Cooked Sweet Potatoes
1. Always reheat refrigerated sweet potatoes before eating to avoid the cold air in the refrigerator affecting your health. Reheating also sterilizes them again, which is beneficial for your body.
2. Refrigerated sweet potatoes are harder to digest than freshly steamed ones. It's best to steam only what you plan to eat for optimal health.
3. Refrigerated sweet potatoes are more likely to become starchy and cause bloating. Reduce portion sizes when consuming them.
