In comparison to the common beef casings from Brazil, beef small intestines from the following countries were tested for their applicability as natural casings for cervelat, a typical Swiss boiled sausage: Brazil (BRA, control), Uruguay (URU), Argentine (ARG), Paraguay (PAR), Australia (AUS), New Zealand (NZL) and Panama (PAN). The sausages were produced with the different casings in one batch according to a typical recipe for cervelat. In comparison to the beef casings from BRA, URU, ARG and PAR, large fat deposits and colour changes were seen in AUS-, NZL- and PAN-casings which were followed by adverse sensory effects (rancidity, colour) in the final products. The occurrence of mucous areas in the casings from BRA, ARG and PAR as well as the thinner URU-casings showed no influence on sensory traits (cold and grilled). No significant differences between the different cervelat types could be seen in texture parameters, neither by instrumental nor by sensorial analyses. It can be concluded from the present study, that beef casings from URU, ARG and PAR can be used as good alternatives to the common BRA beef casings for the cervelat production. Beside the origin, processing quality, storage time and possibilities of importation (available quantities, authorisations) have also to be considered when evaluating alternative cervelat casings.
Soya-, cereal-, seed- or nut-based plant drinks are consumed increasingly frequently as milk substitutes. Agroscope researchers have studied the macro- and micronutrients in these drinks and have identified major differences between the plant drinks themselves as well as in comparison with milk.
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.
