Preserved essence is a chemical substance to keep food stay fresh from rotten microorganism includes bacteria, fungus or yeast. It stops deterioration or fermentation (Winarno & Jenie, 1984). While dye essence is a chemical substance of food to make its appearance looks better (Winarno & Jenie, 1984). The aim of this research is to address students? knowledge about preserved and dye essence in food, kinds of preserved and dye essence, identifying food which contain those essence and the effect when consume those food. I used 200 students as sample population by using random sampling so I get 30 respondents. I used descriptive research. Data is collected by questioner technique and analyzed by presentation technique. The result shows that students? knowledge of preserved and dye essence is good around (83%), their knowledge about kinds of those substance is good around (63%), their identifying about food that have those chemical substances is good around (64%), their knowledge about food characteristics of those substance is about (73%), and their knowledge of the dangerous when consume those food is about (70%). By that data we can conclude that their knowledge about those chemical substance. better than their knowledge of kinds of chemical substances in food. Suggestion here, hopefully both of teachers and students can applied their knowledge of health food consume better especially food without those dangerous chemical substances.
