Multigrain beverages are very beneficial products as functional drinks designed with the combination of bioactive substances of various cereals within liquid media. These healthy beverages contain high soluble fiber and polyphenols. The soluble fiber in the beverages slows down the digestion and absorption of the beverage and lowers their glycemic index. Polyphenols are able to act as scavengers of the free radicals that occur within the human body due to their high antioxidant capacity. Multigrain beverages can be produced with milk or water. Their processing can include steps of soaking, malting, sprouting, grinding, cooking, and/or filtering. Additives can also be included in the formulation for improving the overall quality of these drinks. To obtain a fermented beverage or prebiotic, a fermentation stage is required. Enzyme treatment can be used for non-fermented beverages. Kunan-Zaki made from maize and millet, Champuz produced by fermentation of corn and rice, and Kali obtained from fermented rice are examples of multigrain functional beverages [62]. Apart from these, some of the known multigrain beverages are listed below in Table 3.1 with their countries of origin.
