Description: Refers to typical maize starch production in Germany. This technology includes the following manufacturing steps: mechanical separation of impurities; soaking of the maize grains for about 40 hours in 50 °C warm process water; milling of the soaked maize and separation of the germ. The germ is dried and pressed into corn oil; mechanical separation of starch from other components; mechanical desiccation and thermal drying of the extracted starch to obtain a final product with a maximum water content of 14% by weight; evaporation of the process water to obtain the by-products of maize such as gluten and maize-gluten feed.

Comment: This dataset represents the production of 1 kg of maize starch with a water content of 14% by weight. [This dataset was already contained in the ecoinvent database version 2. It was not individually updated during the transfer to ecoinvent version 3. Life Cycle Impact Assessment results may still have changed, as they are affected by changes in the supply chain, i.e. in other datasets. This dataset was generated following the ecoinvent quality guidelines for version 2. It may have been subject to central changes described in the ecoinvent version 3 change report (http://www.ecoinvent.org/database/ecoinvent-version-3/reports-of-changes/), and the results of the central updates were reviewed extensively. The changes added e.g. consistent water flows and other information throughout the database. The documentation of this dataset can be found in the ecoinvent reports of version 2, which are still available via the ecoinvent website. The change report linked above covers all central changes that were made during the conversion process.]
