Abstract

Scientific studies on poisonous food plants e.g. Dioscorea hispida, Manihot esculenta, Prunus cerasus showed that its roots and leaves contains toxic compounds and can only be consumed after the compounds are removed. Traditionally, the roots of poisonous plant were peeled, sliced and soaked in flowing water such as in a river up to three days for detoxifying process. This research introduced the development of a standalone automatic toxicity removal machine which consists of a microcontroller, solenoid valves, sensors, water pump, electrical circuitry and robust machine structure. During operation process, sliced or blended roots were inserted into machine basket, and the user must push the START button at the controller box to switch on the water pump. The vortex created by the pump caused the water to circulate thus aiding the removal of the toxic compound from the food samples. Contaminated water is automatically removed from the machine after outlet solenoid valve is triggered by detecting the intensity sensor. At same time when the level of water in container is decreased, the inlet solenoid valve will open by detecting the ultrasonic sensor for initiating the flow of fresh water into the machine. From the experiments, the process for removing toxic compound is achieved by showing it significance according to pH values and fish survival rate. Raw roots in which toxic compounds were removed by this machine were cooked and were found safe to be consumed by human. This automated machine can save time and is more effective for removing toxic compounds from poisonous food plants compared with a traditional method and can function as a stand-alone machine.
