A previous study has shown the small variation in the concentration of conjugated linoleic acids (CLA) in alpine dairy products during the grazing period. The present study complements our knowledge of the influence of grazing period on the concentration of other fatty acids in alpine dairy products. Generally, the concentration of these fatty acids was also relatively stable during all the period except for a few particular fatty acids. For instance, the concentration of palmitic acid decreases and that of stearic acid increases at the beginning of the grazing period. It was also found that there was an increase in the concentration of C18:1 t10-11 fatty acids at the beginning of the season, a relatively small variation during the whole season followed by a decrease in these concentrations at the end of the summer. A similar trend was observed for the CLA.
Cheese varieties from Switzerland are characterised according to various criteria. Agroscope analysed the free volatile carboxylic acids in ten cheese varieties and demonstrated that the latter are suitable for characterisation and differentiation.

Safeguarding the clonal diversity of Muscats in the Valais has enabled the characterisation of 42 Muscat à petits grains and 36 Moscato Giallo clones. The characteristics of the two are quite distinct, particularly their aromatic potential. The best clones will be included in the Swiss certification scheme.
Bread, sauerkraut, cheese, wine, beer, yoghurt, chocolate, coffee, kimchi, tempeh, soy sauce, miso, etc. – all these are fermented foods and are part of our daily diet. What exactly are fermented foods and what role do they play in a healthy and sustainable diet?
