The production of nata de coco is still done by inoculating Acetobacter xylinum directly into the culture medium
of coconut water. This way is always a little left over to use as a starter culture for the next fermentation. This
method has the advantage of easy and cheap. However, this method also has the risk of which culture is used as a
starter culture become susceptible to contamination and death, especially when the storage before being used for the
next fermentation if handled inappropriately.
In addition, the use of nata de coco is not only limited in the field of food, but to the field of medicine and
pharmacy, for example, on an open wound healing process. Therefore, it is necessary a fermentation method to
produce nata containing little or free from biomass. One way is by immobilization of Acetobacter xylinum for
fermentation of nata de coco.
