Tips for selecting pineapples

1. Look at the pulp structure: after cutting, the fruit eyes are shallow and small, the interior is light yellow, and pineapples with thick pulp and small core are high-quality products. ; Inferior pineapples have deep and numerous eyes, large internal tissue gaps, thin pulp and thick core; the flesh of immature pineapples is crisp, hard and white.

2. Look at the hardness of the fruit: press the pineapple gently with your hands. Those that are hard and inelastic are raw pineapples; those that are firm and soft are well-ripened; those that are too sunken or even sunken are over-ripe pineapples; If there is juice overflowing, it means the fruit has gone bad and cannot be eaten anymore.

3. Smell the aroma: You can also judge whether the pineapple is ripe by the strong or light aroma. A slight aroma can be smelled on the skin of ripe pineapples, while the flesh is fragrant. Those with a strong aroma are overripe fruits, which will not be kept for long and are perishable. Those without aroma are mostly picked raw and contain sugar. Obviously insufficient and tasteless.
