hulls
1
壳, 外皮
the outer covering or shell of a seed or fruit
The hull of a fruit refers to the outer covering or protective layer that encases the seeds or edible portion. It is typically tough, fibrous, or leathery in texture and serves to protect the seeds from damage, moisture loss, and external threats such as pests and disease. The hull may also play a role in dispersing seeds, either by aiding in their attachment to animals or by providing a barrier that breaks open to release the seeds when the fruit ripens. In some fruits, such as strawberries and peanuts, the hull is removed before consumption, while in others, such as almonds and walnuts, it remains intact.
