Pengaruh Penambahan Zat Kapur dan Lama Perendaman Terhadap Kadar Sianida pada Singkong (Manihot Esculanta Crantz)

Cassava (Manihot esculenta Crantz) or also known as cassava has a high carbohydrate content and become the third staple food source after maize rice. contains linamarin lotaustralin poisons which belong to cyanogenic glycoside group. Cyanogenetic glycosides are compounds found in plant foodstuffs potentially very toxic because they decompose release hydrogen cyanide. This study aims determine cyanide acid before being soaked lime solution soaking with concentrations of 0.25%, 0.50%, 0.75%, 1% 2% for 2 hours, 4 6 hours. Using argentometry method. Soaking does not affect levels, affects namely long time is hours can reduce levels. up 50%, reduced 62.5% 75% level contained cassava. Based on research, it be concluded that greatly decrease levels Suggestions should try measurements using instrumentation methods.
