ABSTRACT:
Methods and apparatus are disclosed for incorporating a design into the skin of an apple or other fruits or vegetables with a photochemically reactive skin or surface by covering the apples while still on the tree with a bag having a reflective outer surface and a non-reflective inner surface. The bag has at least one aperture to allow for the drainage of fluids out of the bag, and further has a light barrier positioned to block light from entering through the aperture into the interior of the bag. The bagged apples are harvested and transferred to a substantially light-exclusive environment where the bag is removed. A label or symbol is applied to the skin of the apple or fruit and the apple or fruit exposed to artificial light to develop the color of the skin of the apple.
