1, look at Guo Di. The flesh and peel around the pedicel should be bulging and round. Don't just look at the color. Red usually only shows how much sunlight mango receives, but not its freshness. And different varieties of mango have different mature colors. You shouldn't just rely on color to judge whether a mango is ripe, but if you want to use color as a backup indicator, you must first understand what each variety looks like when it is ripe.

2, pay attention to spots. Although not sure, if the mango skin has some brown spots or stripes, it is probably ripe.

3. Choose sweet mango. Smell the fragrance around the fruit base. If there is a strong fruit fragrance, it is probably completely ripe.

4. Gently squeeze the mango. When you squeeze mango, you should feel it rebound or shrink. Soft mango is a mature mango.

5. Feel the peel. Gently rub your fingertips on the surface of mango. Mature mango peel often has some fruit lines.

6. Judge its weight. Pick up the mango with your hands and feel its weight. Compared with their size, mature mangoes feel heavier and heavier than raw mangoes.
