COLORGUARD is a tool designed to detect the presence of artificial colors in food and beverages. This tool was created to help users identify coloring materials that are unsafe for health in an easy, fast and environmentally friendly way. This tool is also very useful for users in understanding the importance of food safety. The purpose of this project was to raise awareness about the dangers of excessive use of artificial coloring materials and promote the use of natural coloring materials in everyday life. OBJECTIVE: The purpose of our product is to detect artificial coloring agents in food and beverages, promote the use of natural substances as chemical indicators, and raise awareness about the dangers of synthetic coloring agents. METHODOLOGY:  Cut the purple cabbage into small pieces so that the natural color comes out more easily and effectively, then carefully put all the chopped cabbage into a clean pot and add enough hot water to fully submerge the cabbage, proceed to boil the purple cabbage over medium heat for 10–15 minutes while observing as the water gradually changes to a rich, dark purple color, after which carefully filter the colored water using a coffee filter to obtain a clear and vibrant purple cabbage solution free from solid particles, then gently transfer the filtered purple cabbage solution into a drop bottle for convenient and precise use in experiments or demonstrations, and with that, following all these steps in sequence and ensuring the solution is well-prepared, our project, COLORGUARD is now fully complete and ready to be showcased. RESULT: This project aims to increase consumer awareness of food safety, reduce the use of artificial coloring in the food industry, cultivate student creativity in science and innovation, and support healthy and sustainable lifestyle practices. CONCLUSION: This product proves that purple cabbage functions effectively as a natural color detector for identifying artificial coloring in food and drinks. The anthocyanin pigment in purple cabbage changes color when it reacts with synthetic substances, showing the presence of chemical additives. This simple, low-cost, and eco-friendly method helps promote food safety and encourages the use of natural materials in science and daily life.
