Keep the fibers in the dye bath for a certain period of time to ensure thorough coloration. After dyeing, rinse the fibers thoroughly to remove any excess dye.
For food coloring, it is necessary to first dissolve the Acid Red 18 in a small amount of water or other suitable solvents according to the recipe requirements. Then, add it to the food product under gentle agitation to ensure uniform distribution. Make sure to follow the maximum allowable usage limits set by food safety regulations.
