Ground nuts were stored in an atmosphere of pure nitrogen or pure oxygen. Storage of ground walnuts in an atmosphere of nitrogen results in slow oxidation, low levels of oxidation degradation products and better stability of unsaturated fatty acids.

The red-coloured apple cultivar (Gala) depends more on the location in the canopy than the less-coloured cultivars (Fuji and Braeburn). The colour development in Fuji apples is considerably slower, with a much larger variation in stage of development. The location in the canopy affects all aspects of biological variation (biological shift factor and asymptotic starting level of colouration) for all three colour aspects L*, a* and b*, but only the mean value, not the standard deviation. The biological shift factors per colour aspects are linearly related. Once induced, variation remains constant during development.

Apples from organic and integrated production were analysed. The results show that organically grown apples contain more polyphenols, have higher antioxidative potential and a higher ratio of the isotope 15N .
