Obwohl viele Menschen Pasteurisierung vor allem mit der Herstellung von Wintervorräten in Verbindung bringen, wissen nur wenige, welche komplexen biologischen und chemischen Mechanismen hinter diesem Verfahren stecken und warum seine korrekte Durchführung ein entscheidender Faktor für die mikrobiologische Sicherheit von Lebensmitteln ist. Eine unsachgemäße Anwendung – etwa durch zu kurze Erhitzungszeiten, unzureichende Temperaturen oder falsches Abkühlen – kann optimale Bedingungen für das Überleben und die Vermehrung pathogener Bakterien wie *Clostridium botulinum* oder *Salmonella* schaffen, was wiederum zu schweren Lebensmittelvergiftungen führen kann, die sich durch Symptome wie Erbrechen, Durchfall und in extremen Fällen sogar Lebensgefahr äußern.
Pasteurisation
Pasteurization is the process of heating raw materials at a temperature not exceeding 100OC with an acidic pH of less than 4,5 °C. It is most commonly carried out in the range of 65 85OC. As a result of the current mechanism, pathogenic microbes are destroyed, and the product's durability is prolonged, as the vegetable forms are virtually completely destroyed. In the case of acidic ingredients with a pH below 4, 5 °C, it enables a complete microbiological durability. We also distinguish different pasteurisation methods, which differ in the time of curing and timing: pasteurizing products (long-term) Continuous processing is also used during the normal process.
How do you pasteurise the jars?
I'm sure everyone, even if you've ever seen how to pasture a jar of cold stuff. The process is easy and it doesn't require much skill. All you have to do is in a clean, dry jar (it's a good idea to heat the jar up a bit in the oven or by steaming it out) put the product in, and then close it tightly and put it in a large pot with a spread brush or a special perforated coating to avoid cracking the jar during cooking. It's important that the walls of the jar don't come in contact with each other, the best solution is to wrap the jar in a towel.
Dry pasteurisation
Dry pasteurization is carried out in the oven. At this time the vials should be placed in a cold oven, preferably on a sheet of paper. In this case it is also necessary to be careful not to touch the walls of the vessel. Then the oven should be heated to 170OC with a top-down heating function on. In autumn, when bubbles appear in the jars, the temperature should be reduced to 130OC. At that time the baking process has begun, which should last about.. 30 minutes. After that time, the baker should be turned off, which means pressing, cooking and waiting for the leaves to dry.
