Summer is the harvest season for watermelons. How to choose a ripe watermelon has become a concern for many consumers. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of how to determine whether a watermelon is ripe, and provide structured data for reference.
1. Appearance judgment method
Ripe watermelons usually have the following characteristics in appearance:
| feature | illustrate |
|---|---|
| color | The skin of ripe watermelon is darker in color, dark green or dark green. |
| luster | The epidermis is smooth and shiny, no white frost |
| pattern | The pattern is clear and the contrast is obvious |
| umbilicus | The umbilicus is deeply sunken and the surrounding area is smooth |
2. Percussion listening method
This is the most traditional and commonly used judgment method:
| sound characteristics | Maturity judgment |
|---|---|
| Crisp and loud | immature |
| dull and low | Overripe or spoiled |
| Rich and resonant | Just mature |
3. Weight comparison method
Ripe watermelon has high water content and weighs more for the same volume:
| watermelon size | expected weight |
|---|---|
| Small (diameter 15cm) | 2.5-3.5kg |
| Medium size (diameter 20cm) | 4-6kg |
| Large (diameter 25cm) | 7-10kg |
4. Vine Judgment Method
The state of the watermelon vine can also reflect maturity:
| Vine characteristics | Maturity |
|---|---|
| Green and plump | immature |
| begin to wither | close to maturity |
| completely dry | mature |
5. Professional selection skills
1.Observe "ground spots": Yellow patches will form where the watermelon is in contact with the ground. The larger and yellower the patches, the higher the maturity.
2.Press test: Gently press both ends of the watermelon. If there is slight elasticity, it means the ripeness is moderate.
3.Variety differences: Different varieties of watermelon have slightly different ripening characteristics. For example, the color of seedless watermelon will be slightly lighter than that of seeded watermelon.
6. Saving Tips
1. Whole watermelon can be stored in a cool place for 2-3 weeks.
2. Cut watermelon needs to be refrigerated and is best consumed within 2 days.
3. Watermelon should not be stored together with bananas, apples and other fruits, as it will speed up the ripening process.
