The statistical evaluation of datas collected from 30 commercial Emmental cheeses showed, that the deamination of aspartate to succinate by propionibacteria (aspartate metabolism) increases the risk of late fermentation in Swiss-type cheeses. It is not only the additional carbondioxide which is released during aspartate metabolism which reduces the potential time of storage, but it is also the carbondioxide from the classical propionic acid fermentation, which is intensified by aspartate metabolism. The consequences for the cheese quality are: higher loaves, oval eyes and splits.
At the new Centre of Excellence for Raw-Milk Products, Agroscope and Grangeneuve interviewed test subjects about the popularity of Vacherin Fribourgeois PDO cheeses made from raw and thermised milk. The study showed that the market potential of raw-milk cheeses has not yet been exhausted.
Divico, Agroscope’s new disease-resistant grape variety, is noted for the quality of its wines. Blending trials with the Pinot Noir variety have shown that Divico is also highly suitable for correcting colour intensity in the latter.

As part of the trend towards vegetarian and vegan products, Agroscope looked into the production of plant-based alternatives to soft cheese based on Swiss raw materials.
