The History of Food Colouring
Food coloring is as colorful as its history. It spans thousands of years of cultural, economic, and scientific history.
Ancient food coloring was natural. Egyptians, a prehistoric civilization, used natural food colors. Saffron-dyed rice yellow and hibiscus cakes crimson. Cinnamon and cumin gave their food warm, enticing colors and flavors.
Greeks and Romans followed. Red wine and mulberries were powerful dyes. Romans even used the fish sauce to color their cuisine brown.
In the Middle Ages, Europeans employed spices like saffron for their flavor and golden color. Food coloring became a status symbol at this time. Saffron, due to its exorbitant cost, was linked with luxury and prestige.
Synthetic dyes changed everything in the 19th century. In 1856, Sir William Henry Perkin unintentionally developed Mauveine, the first synthetic color, while synthesizing quinine to treat malaria. Artificial food coloring began here. In rapidly industrializing cultures, synthetic dyes were brilliant, uniform, and mass-produced.
The food business uses natural and artificial food colors today. They improve food and drink appearance and compensate for color loss during storage and processing. As customers become more health-conscious, natural and plant-based colors are returning to the colorful history of food coloring.
Natural Food Colours: Sources and Benefits
Sources of Natural Food Colours
Natural food colors come from a variety of sources in nature. Most sources are plants, which offer a wide range of colors. Beetroot is deep red, while turmeric is bright yellow. Spinach and spirulina are great sources of green, whereas grapes and eggplant provide purple. Saffron, paprika, and berries are plant-based sources.
Sources of natural food colors include minerals and animals. Caramel color comes from boiling sugar, while cochineal, a red dye, comes from the scale bug Dactylopius coccus.
Benefits of Natural Food Colours
Natural food colors have many advantages, including safety. They’re natural and don’t contain synthetic ingredients like artificial colors, lowering allergy risk.
Natural food colors are also healthier. They have phytonutrients, vitamins, and antioxidants from food sources. Carrot beta-carotene gives vitamin A an orange color.
