On the other hand, the huge number of duku does not fulfill the needed of domestic and export demand, it because the duku of the "shelf life" duku relatively short. So the fruit is blackened and rotten. Therefore it is necessary for fruit preservation methods, which is known as an edible coating. This method use shrimp shell waste as a raw material of chitosan and further synthesized into a coating on the skin of duku.

This study, known waste shrimp shells can be made of chitosan and used as leather upholstery fruit or edible coating for duku in order to have a "shelf life" longer. Edible coating of chitosan is able to maintain the condition of the fruit approximately 2% of the fruit skin condition before coating. This paper explained the procedure of chitosan-making to become edible coating.
