Core casing
The core, lat. Capsula nucleorum mali , is the part of pome fruit , especially apples or pears, which is normally spurned when eaten, which contains the inside of the fruit with the seeds .
etymology
The expression Griebs is widespread in the landscape and comes from the late Middle High German grubs, roughly , the origin is unclear according to the Duden ; a relationship with Griebe ("Grobes") is assumed . A large number of other terms for the core housing are common in the German-speaking area, such as the Butzen or Krotzen in southern German. In the Swiss dialects terms are of similar but dying Butze in Basel on Üürbsi in Aargau to Bütschgi in the greater Zurich spread - in the Eastern Bitzgi . Gigetschi in Solothurn or Grübschi and similar forms in Bern come from western German-speaking Switzerland . The similar Gütschi comes from Glarus . Various other terms exist.
botany
From a botanical point of view, the core is a wreath of follicles (five in apples, four in pears), which are enclosed in the pulp formed by the flower base of the false fruit ( apple fruit ). The so-called stone apples, such as the medlar or the service tree , are not soft-skinned follicles, but hard-shelled nuts .
Determination of apple varieties
Some properties of the core casing and the apple pips (seeds of Malus domestica) can be used for the typical task of a pomologist , the determination of apple varieties .
The five core chambers belonging to each core show typical properties for certain types. The core house walls, which are recognizable as fine structures in the vertical section of the apple (from the calyx to the stem pit), can take on different shapes. The shapes are easy to distinguish: crescent, arch, bean, ear and backpack-shaped.
Taken alone, these shapes cannot yet be used to determine an apple variety, but the shapes of the core chambers provide additional differentiation aids for otherwise very similar apple varieties. As a second property, besides the shape, the position of the core chambers is to be considered, here a distinction is made between cup-near, stem-near and core chambers in the middle of the fruit. In addition, two further properties can be used for a determination. The walls of the core houses can appear smooth or rough, or "torn cotton wool". The second property is shown when the apple is cut horizontally, it is easy to observe that the core houses of individual varieties are isolated and closed, while with other varieties there is a connection between the chambers. This connection is often so pronounced that a so-called axial cavity can be seen.

Apple corer
In the kitchen, the core casing is removed with an apple cutter (also known as a core casing cutter ) if the apple is to remain whole. The kitchen appliance consists of a tube with a diameter of about 15 mm with a cutting edge. The tube is drilled through from the base of the stem to the other end, then rotated 360 degrees around its longitudinal axis and, after pulling out, contains the stem, the core and the remains of the apple blossom.
