A sweet gelatinous delicacy, an in vitro culture medium for
plants in tubes, vegetable leather, a fertilizer for orchids, here are some of
the most surprising uses of coconut water...
Coconut water (94% water) contains growth promoting substances that can influence in vitro cultures including inorganic ions, amino acids, organic acids, vitamins, sugars, sugar alcohols, lipids, nitrogenous compounds and phytohormones. It is an important additive in the tissue culture media of several plants, including orchids and traditional Chinese medicinal herbs.
Originating in the Philippines, nata de coco was invented in 1949 by Teódula Kalaw África, a Lipeña scientist graduate of the University of Santo Tomas, as an alternative to the traditional Filipino nata de piña made from pineapples.
Nata de coco, also marketed as coconut gel, is a chewy, translucent, jelly-like food produced by the fermentation of coconut water, which gels through the production of microbial cellulose by a bacteria (Komagataeibacter xylinus). It is most commonly sweetened as a candy or dessert, and can accompany a variety of foods, including pickles, drinks, ice cream, puddings, and fruit cocktails.
Coconut leather is the latest eco fabric to hit the fashion scene for sustainable leather alternatives. India-based startup, Malai, have developed bacterial cellulose grown from leftover coconut water and successfully converted the biocomposite into a substance that resembles traditional leather.
