Characteristics of water solubility and color on edible film from bioselulosanatanirasiwalan with the additional of glycerol
Indonesia entered the ranks second in the world as a producer of plastic waste into the sea after China. Most of the plastic packaging is causing environmental pollution, unbiodegradable, expensive in recycling and contamination of foodstuffs packaged due to certain substances that migrate into the food. Edible film is a thin layer of transparent and made of materials that can be eaten very prospective and secure to provide selective detentions against the transfer of gas, steam, water and dissolved materials as well as protection against mechanical damage. Product development nata much utilized as raw material for paper and edible film, nata contains bioselulosa which is produced by the bacterium Acetobacterxylinum. So the researchers develop alternative modification of cellulose from natanirasiwalan. Glycerol is one of plasticizer selected researchers to be added in the manufacture of edible film. The purpose of this research is to know the concentration of glycerol that is most appropriate to get the edible film solubility characteristicsbioselulosanatanirasiwalan and to find out the optimum concentration of glycerol that is most appropriate to get the characteristics ofcolors edible film made from bioselulosanatanirasiwalan which is optimum. The research was carried out in December 2016-June 2017. Methods this study used a randomized complete design with four treatments and three replicates. The results of this study is the most appropriate concentration to get characteristics of water solubility on edible film bioselulosanatanirasiwalan is on treatment D with the addition of glycerol 30% of 0.42% and on the characteristics of color by value L (77.45), a (0.723) and b (9.96).
