kaasajastamiseks

Kaasajastamiseks is a traditional Estonian method of preserving milk, typically cow's milk, by fermenting it with specific lactic acid bacteria. This process is often used to create a variety of dairy products, such as kefir, kefir grains, and sour milk. The term "kaasajastamine" translates to "fermentation" in English.

The process of kaasajastamiseks involves several steps. First, the milk is heated to a specific temperature, usually around 85-90 degrees Celsius, to kill any harmful bacteria and to denature the proteins, which helps in the coagulation process. The heated milk is then cooled down to a temperature suitable for fermentation, typically between 25-30 degrees Celsius.

Next, the milk is inoculated with kefir grains, which are a symbiotic culture of bacteria and yeast. These grains contain lactic acid bacteria that convert lactose, the sugar in milk, into lactic acid, which gives the milk its sour taste. The fermentation process can take anywhere from a few hours to several days, depending on the desired level of acidity and the specific strains of bacteria used.

After fermentation, the milk can be strained to remove the kefir grains, resulting in a liquid product known as kefir. The grains can also be separated and used to inoculate new batches of milk, continuing the cycle of fermentation. Alternatively, the fermented milk can be left to coagulate, forming a solid product called kefir curd, which can be used in various culinary applications.

Kaasajastamiseks is a sustainable and traditional method of preserving milk, which has been practiced in Estonia for centuries. It allows for the creation of a variety of dairy products with unique flavors and nutritional benefits. The process is relatively simple and requires minimal equipment, making it accessible to both professional dairies and home-based producers.
