I think there are significant differences between pineapple and pineapple in appearance, taste and eating method. Pineapple has yellow skin, obvious serrated leaves and astringent taste, and needs salt water; Pineapple has light green skin, smooth leaves and sweet taste. Pineapple needs to be removed if it has meat thorns, and pineapple can be peeled without meat thorns. When choosing to eat, you can choose according to your personal preferences and tastes to avoid eating too many immature fruits.
