The purpose of this research is For the production and analysis of citric acid from a sample 2 type is jackfruit seed dry and seed with Rambutan seed drying with fungi and Aspergillus niger
. Using a recipe 1-6 control not shake shake.As an analysis technique the chromatography paper Method and titration. Determination of moisture content of the sample.Found Jackfruit seed moisture than dry rambutan seed drying.Analysis method of titration in jackfruit seed dry and rambutan seed drying.Found Optimal conditions for production of citric acid.Is The conditions do not shake When using the jackfruit seed dry and rambutan seed drying. 10.00 quantity.To citric acid More than 15.00
in which foods to the jackfruit seed drying. Rambutan seed and dry volume rate when adding sugar - glucose to citric acid more than no sugar - glucose, qualitative analysis Method of paper chromatography and paper.And the crystallization of citric acid cannot be crystallized. Because the fermentation has concentration is not sufficient to crystallizing citric acid
