Influence of atmosphere on the oxidation of ground walnut during storage at 20 °C

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.

Effect of location in the canopy on the colour development of three apple cultivars during growth

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.

Characterization of Slovenian apples with respect to their botanical and geographical origin and agricultural production practice

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 .
