Can fresh blueberries be stored at room temperature

Fresh blueberries can be stored at room temperature, but it is recommended to refrigerate them to extend their shelf life. The storage method of blueberries is mainly affected by temperature, humidity, ventilation conditions, maturity, and storage containers. Fresh blueberries can usually be stored at room temperature for 1-2 days and are suitable for consumption within a short period of time. When stored at room temperature, blueberries should be spread flat in a breathable container to avoid direct sunlight and high temperature environments. Natural fruit powder on the surface of unwashed blueberries can help resist bacteria, and it is recommended to wash them before consumption. If the ambient temperature exceeds 25 degrees Celsius or the humidity is high, blueberries are prone to softening and mold growth. At this time, they should be consumed as soon as possible or transferred to the refrigerator. When blueberries are fully ripe or partially damaged, storing them at room temperature will accelerate spoilage. This type of blueberry may experience juice leakage or mold spots within 6-8 hours in high temperature environments. During the summer or rainy season, blueberries stored at room temperature for more than half a day should be carefully inspected for any fermented or sticky taste. Some varieties, such as high sugar blueberries, are more likely to attract fruit flies and need to be covered with insect proof mesh when stored at room temperature. To maximize the preservation of nutrition and taste, it is recommended to pack fresh blueberries in a fresh-keeping box and refrigerate them at a temperature controlled between 0-4 degrees Celsius. Keep dry and avoid squeezing during storage, and use kitchen paper to absorb excess moisture. If long-term storage is required, it can be cleaned, dried, and frozen for better flavor when used to make milkshakes or baked goods. The recommended daily intake is 50-100 grams, and those with gastrointestinal sensitivity should avoid eating on an empty stomach.
