For both basic products, the application of gene technology is possible. Maltose is produced from plant starch during the process of saccharification. Maize starch can partly consist of genetically modified maize, especially when raw materials are imported out of the USA or Argentina. In the EU, genetically modified maize is grown on a comparativelly small area and nonetheless is not used as raw material for foodstuff. This may change in the case that the cultivation of GM maize increases in significance. Ingredients derived from several types of GM maize are approved in the EU. In the future also: starch from potatoes and wheat. Enzymes solubilise plant starch and metabolise it into compounds that are distinguished as ingredients and additives. Several of these enzymes are produced with help of GM microorganisms such as amylases, glucose-isomerase, pullulanase. Lactose: from whey. http://www.thegoodscentscompany.com/ Local: Maltol, 3-hydroxy-2-methyl-4-pyrone, is a white crystalline powder featuring caramellike odor; soluble in water and glycerine, slightly soluble in alcohols, chloroform; melting point 161 C. It is used as a flavoring agent in bread and cakes. Maltol and its derivatives are used as versatile flavor enhancer and modifier ( sweet, caramel, fruity, strawberry ) in foods, wines, and perfumes.
