Whole milk was pasteurised with a direct method at 125 °C and an indirect method at 115 °C. Immediately after heating and storage at 5 °C during 1 and 4 weeks, the vitamins B1, B6, B12 as well as folic acid were examined. No losses due to storage (storage losses) were detected with Vitamin B12 and folic acid. Vitamin B6 showed losses in a range of 0 % (indirect variant) and 7 % (directly heated). The losses of vitamin B1 were between 5 % (indirectly) and 15 % (directly).In order to avoid losses due to storage, sufficient protection from light and gas through packaging as well as cool storage are required.
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.
