Due to the rising demand for natural food additives, food processing industries are shifting away from chemical-free additives and replacing them with natural food additives such as stevia, coconut sugar, black pepper oleoresin, gum arabic, carrageenan, etc. There are various segments of food additives such as preservatives, sweeteners, food colorants, antioxidants, emulsifiers, flavour enhancers, thickeners, etc. Natural food colorants are produced from parts of plants, algae, fungi, and mould. Natural sweeteners include thaumatin, glucose-fructose syrup, xylitol, neohesperidin DC, etc. As synthetic food additives are less expensive compared to natural food additives, still many food processing industries are using synthetic food additives.
