Vitamin
An organic micronutrient that the body requires but cannot synthesize in sufficient amounts, so it must be obtained from food. Each vitamin has its own characteristic deficiency disease.
Instant noodles are yellow because of added vitamin B2. In the 1980s, ramen companies began adding vitamin B2 to address nutritional concerns. The alternate name for vitamin B2, "riboflavin," contains "flavin"—derived from the Latin word "flavus," meaning yellow.
