The fatty acid composition was determined in ewe’s milk (pasture feeding), originating from plain, subalpine and alpine areas. Significant differences were encountered in the milk of the three origins. Compared to cow milk, the fatty acids which differed significantly depending on the altitude were often different, probably because of the different fodder specific for sheep (grazing on natural grassland, addition of concentrates containing vegetable fatty acids). However, similarly to cow milk, the concentrations of CLA and omega-3 fatty acids in sheep milk was higher in the milk originating from the higher altitudes.
Plants and microorganisms can perceive and respond to sound waves. In a review of the literature, Agroscope analysed various publications on this topic. The studies show that sound can lead to positive effects on physiology in the form of improved growth, development and disease resistance.
The war in Ukraine, dry spells and droughts followed by heavy rainfall and flooding are major challenges for our food systems. But the problems that they bring to light are nothing new – and solutions are already to hand.
Biogenic amines in foods represent a health risk. Researchers from Agroscope and INRAE investigated the formation of these undesirable substances in raclette cheeses by the bacterium Morganella morganii.
