An intermediate food product for the production of a fiber-enriched food end product by mixing and further processing it with a liquid-containing end product addition comprises dietary fibers made of insoluble fruit and/or vegetable fibers that are mixed with a base liquid. For this purpose, the intermediate food product is preportioned and packaged in a packaging that can be transported, stating an amount of the end product addition to be used which ensures a dietary fiber portion of at least 3.0 wt-% of the food end product. The dietary fibers and the base liquid are pretreated by applying shearing forces and have a paste-like consistency.
