The treatment of soaking time 72 hours in 7,5% brine has 18,75 ppm HCN, 41,51% starch, 1,59% fiber, 10,8% water, 6,01% ash, 97,84 color degree and preference taste of tiwul 2,1 betweendislike and like. The treatment of soaking time 72 hours in 5% brine has 19,62 ppm HCN, 50,49% starch, 1,58% fiber, 9,64% water, 4,34% ash , 98,41 color degree, and preference taste of tiwul 2,87 between dislike and like.
