First, harvested mangosteen are sorted and graded in three categories: Super I, Super II and Super III, with the former having the highest quality (stalk is fresh green, skin with no bruises).
After that, there is individual cleaning with air pressure and brushing. The fruit is sorted again but by weight. The fruit is then packed and stored in cold rooms.
The Indonesian Agricultural Quarantine Agency then inspects if the fruit meets the requirements of importers, and issue a phytosanitary certificate if approved.
