ANALISIS KANDUNGAN PROTEIN PADA NATA BUAH NANGKA (Arthocarpus heterophyllus)

This study aims to determine how much protein content in Nata made from jackfruit (Artocarpus heterophyllus). The method in this study was carried out by taking 1 gram sample of jackfruit nata that had been weighed, then adding 1 tablespoon of selenium mixture reagent, adding 20 ml of sulfuric acid and then letting it sit for one day. Then it is heated in a fume hood using a hot plate until it changes color from black to a clear color. Let stand for one day then distilled for 4 minutes and then added with distilled water, 0.1% phenolphthalein, sodium. After that, 20 ml of boric acid was added, then distilled, added sodium hydroxide, then titrated, then added 0.1 N Hcl solution to the titration device, then added 3 drops of Conway's solution, then titrated until the color changed to clear. The result is that the protein content in 1 gram of Nata is 0.69%, so that Nata from Jackfruit is suitable for consumption as an alternative food.Keywords : Jackfruit (Artocarpus heterophyllus),Nata , Protein
