Corn or maize is native to America but is now grown throughout the world. In grain form it is the staple diet for American Indians in Mexico, Peru and Southern North America. The Maori were given maize by American sailors which they grew and ate both fresh and fermented. The fermented corn was known as kaanga. Its strong smell didn't appeal to Pakeha who ate corn mainly as a grain. Eventually a sweet form was developed, and hence the name sweetcorn, it wasn't until the 1960's that sweetcorn became a really popular fresh vegetable. Several varieties are available including some with white kernels and others with a mix of yellow and white kernels. Varieties differ in sweetness. Recently the supersweet varieties have become popular, with Honey 'n' Pearl being the most widely grown. Sweetcorn is a very good source of fiber, protein and starch. corn is a great source of vitamin A, fiber, and other nutrients. Malting is a process applied to cereal grains, in which the grains are made to germinate by soaking in water and are then quickly halted from germinating further by drying/heating with hot air. Thus, malting is a combination of two processes: the sprouting process and the kiln-drying process. These latter terms are often preferred when referring to the field of brewing for batches of beer or other beverages as they provide more in-depth information. The term "malt" refers to several products of the process: the grains to which this process has been applied, for example malted barley; the sugar, heavy in maltose, derived from such grains, such as the baker's malt used in various cereals; or a product based on malted milk, similar to a malted milkshake (i.e., "malts"). An extract is a substance made by extracting a part of a raw material, often by using a solvent such as ethanol or water. Extracts may be sold as tinctures or in powder form. The aromatic principles of many spices, nuts, herbs, fruits, etc., and some flowers, are marketed as extracts, among the best known of true extracts being almond, cinnamon, cloves, ginger, lemon, nutmeg, orange, peppermint, pistachio, rose, spearmint, vanilla, violet, and wintergreen.
