Sometimes when you buy a dragon fruit, you can't finish it all at once, so you need to learn some preservation methods. It must be emphasized that the shelf life of a cut dragon fruit is different from an uncut one, and the preservation methods are also different, which requires everyone's attention.
1. The storage temperature for dragon fruit in a fresh-keeping cold storage is 3°C to 6°C, with a relative humidity of 75%-90%. Note that the cold storage temperature for dragon fruit should not be set below 1°C to prevent frost damage. Dragon fruit, after harvest, is a fruit with a low respiration rate. And due to its thick peel and waxy protective layer, it is extremely resistant to storage and transportation. At low temperatures of 5-9°C, freshly picked dragon fruit, if not squeezed or bumped, can be stored for more than a month. At room temperature of 25-30°C, the shelf life can exceed two weeks.
2. How long can a cut dragon fruit be stored
Because dragon fruits grow in tropical and subtropical regions, they are sensitive to low temperatures due to their growing climate conditions. When placed in a refrigerator, they are easily frost-damaged, and the peel will become pitted with some dark brown spots. Not only are the nutrients destroyed, but it also spoils easily. After a few more days, the flesh will turn brown and start to rot.
1. Store in a cool, shaded place. If the weather is not particularly hot, a cut dragon fruit can generally be kept for a day in a cool, shaded place. However, it's best not to eat it overnight. Of course, it's better to finish it as soon as possible.
2. Refrigerate at 15°C. If you can't finish a cut dragon fruit, you can wrap it in plastic wrap and then refrigerate it. However, because dragon fruit is a tropical fruit, you should pay attention to setting the refrigerator to 15°C. At this temperature, it should be good for two days.
3. It's best to buy and eat it fresh. After cutting a dragon fruit, it's best to eat all of it. This way, you can ensure the freshness and hygiene of the dragon fruit, and it's also convenient for storage. This is the most recommended method.
4. Cut fruit is prone to bacteria. Not just dragon fruit, but other fruits are the same. After cutting, it's best not to store them; it's best to eat them immediately. The longer they are stored, the more bacteria will grow on them. Even refrigerated, bacterial growth cannot be avoided. They are also prone to spoilage in hot weather.
3. Preservation methods for dragon fruit
Dragon fruit, after harvest, is a fruit with a low respiration rate. And due to its thick peel and waxy protective layer, it is extremely resistant to storage and transportation. At low temperatures of 5-9°C, freshly picked dragon fruit, if not squeezed or bumped, can be stored for more than a month. At room temperature of 25-30°C, the shelf life can exceed two weeks.
It can be preserved for more than 15 days at room temperature. If boxed and refrigerated, with a storage temperature of around 15°C, the storage time can be as long as a month or more. However, in hot seasons, after harvest, dragon fruit must be placed in a cool place to cool down and dissipate heat, and then refrigerated to help with preservation.
Dragon fruit is a tropical fruit, so it's best to buy and eat it fresh. Some friends are used to storing the remaining half of a cut dragon fruit in the refrigerator. In fact, this preservation method is not scientific. Because dragon fruits grow in tropical and subtropical regions, they are sensitive to low temperatures due to their growing climate conditions. When placed in a refrigerator, they are easily frost-damaged, and the peel will become pitted with some dark brown spots. Not only are the nutrients destroyed, but it also spoils easily.
