The process of flow bed drying has been used for the conservation of several different products for some time. Preliminary experiments for the conservation of lactic acid bacteria gave positive results. Commercial use of the flow bed-drying technology for the conservation and confectioning of microorganisms used in fermentation processes seems to be realisable, however, further specific studies still have to be done.
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.
