Suggest ways to protect food from bacteria.

Protecting food from bacteria is very important – by contaminating food, they can cause infection in the body. There are different ways to do this. For example, boiling will kill a lot of bacteria and spores. Pasteurization is heating to a temperature of 80 degrees without boiling. This kills fewer bacteria and survives spores, but the product retains many nutrients and vitamins. You can also use preservation – this will allow you to preserve products for a long time using preservatives – vinegar, ginger, salt. If food needs to be stored for a short time, temperature reduction – that is, refrigerator conditions – can be used. At low temperatures, spores will not germinate and bacteria will multiply. Food should be placed in the refrigerator in a clean container with the lid closed. If you lower the temperature below zero, then it will freeze the product. This way vitamins are preserved and the product is not spoiled by bacteria. Modern methods include placing a food product in a vacuum.
