Information zu Trinkkokosnüssen
Hier ein paar Infos zur Behandlung von Trinkkokosnüssen von Coconow:
In Thailand the standard practice for young coconut after peeling off the green portion is dipping in 1-3% Sodium metabisulfite solution for 3 minutes.
This is to prevent mold growth on the surface of the peeled young coconut. In addition the chemical prevent the brown color development on the surface of peeled young coconut.
Sodium metabisulfite is also currently used in shipping grapes from the United States and other producing countries around the world. Anyone can observe this practice when open any box of grapes. It is the large paper envelope on top of grapes. This envelope appears empty because during transit the chemical react with water and give off Sulfur dioxide that control fungal development and browning of grapes.
In peeled potato selling in Europe and US, all has been dipped in sodium metabisulfite as well.
Anyone can look for information about the above practice in the USDA Handbook # 66. It is available online. Just search for ‘usda handbook 66’ in Google or any search engine. Once get on to the book content, look for coconut.
In Thailand, Kasetsart University has conducted a work to determine the possibility that Sodium metabisulfite may get into the coconut pulp and water. It was found that the standard practice is safe. No residue was found inside young coconut. Only when the coconuts are cracked, then the residue can be found. The residue found in the crack coconut was below the Codex’s Minimal Residue Limit of 10 ppm for grapes.
