Fruit bowl
The fruit peel , also called peel for short , is the outer shell of a fruit . You can membranous (z. B. the apple or the peach ), leathery (as in the citrus fruits ) or woody (as in the walnut fruit , also called because of their hard shell nuts are referred to) be.
Botanically, the shell can only consist of the exocarp, or the entire pericarp can be fused together to form a shell (as in the case of the nut fruits).
Various nutritionally important ingredients such as vitamins and trace elements are more concentrated in and under the peel , so that nutritional physiologists recommend eating fruits with the peel if they are suitable for consumption. This is countered by hygienic concerns and the possible accumulation of pesticides and polyethylene wax (E 914) etc. in the bowl.
