In this simple study used samples such as lime, tomato, carrot, bengkoang cucumber. As a control used 500 vitamin C tablets taken as many as 20 grains dissolved in 10 ml air.Sebagai indicator used betadine solution containing betadine containing povidone iodine 10% which is equivalent to 1% iodine.
