How to ferment milk at home?
Milk is a tasty and healthy product that gives pleasure to young children, but not every adult organism easily tolerates lactose. There is a simple way out of this situation - to consume sour-milk products. They are both tasty and healthy. Milk fermented with certain bacteria improves the functioning of the digestive system, helps with dysbacteriosis, flatulence, restores beneficial flora after taking antibiotics and heavy anesthesia. At home, it is not necessary to limit yourself to yogurt, you can cook fermented baked milk, kefir, yogurt and even cheese.
Peculiarities
It is enough to throw a crust of bread into natural milk and wait for it to turn sour. With an industrial product, everything is not so simple, it has a long shelf life, which indicates the presence of preservatives and stabilizers. Even worse if the milk is powdered. Such a product is kept warm for days and instead of souring, a rotten, rancid liquid is obtained. From the foregoing, we can conclude: good fermented milk products are obtained from whole homemade milk. If the product is purchased in a distribution network, you should pay attention to expiration dates. The drink must be fresh, with the minimum recommended shelf life. Powdered milk is not suitable for quality fermented milk products.
The usual method of souring is yogurt.If you need kefir, yogurt or fermented baked milk, use special additives containing beneficial cultures of kefir or yogurt bacteria. Sachets with dry bifidobacteria are purchased at pharmacies. Supplements in the form of dairy dressings are obtained from dairies or from friends who purchased them at the dairy and maintain the viability of bacteria constantly.
Having obtained the first kefir or yogurt by fermentation, in the future, a fermented milk product already produced independently can be added to milk.
curdled milk
To prepare yogurt, milk can be boiled, but just warm is also suitable. In winter, it is difficult to do without a yogurt maker or other warming devices. You can wrap milk in a blanket. In summer, in a warm kitchen, the product turns sour on its own. To speed up the process, 0.5 cups of the previous curdled milk or a crust of bread are added to 1 liter of milk, leaving the composition for 10-12 hours.
The finished fermented milk product should be stored in the refrigerator, try to use it within 3-4 days.
Kefir, yogurt
To prepare these drinks, kefir fungus is used, which is also called milk or Tibetan. With its help, a fresh portion of kefir is made daily, and the grown surplus of the fungus is distributed to friends. You can use sourdough from a dairy or good quality kefir (1 tablespoon per 1 liter of milk). The further process of preparing the drink is the same as that of curdled milk.
If you put yogurt bacteria instead of kefir starter and place it in heat, you get homemade yogurt. Children can add their favorite jam or fresh fruit to it. The microflora of yogurt is more demanding on temperature conditions.
Sour-milk bifidumbacterin
Kefir ferment with bifidumbacterin can be bought at any pharmacy.For half a liter of milk, it will need one bottle. This product, due to its biologically active qualities, is useful even for infants. To prepare a drink, pour a little warm milk into a bottle with bifidumbacterin and mix thoroughly. Add the resulting composition to the remaining milk, wrap in a blanket and put on souring. The finished product has a value of no more than seven days, then the bacteria die.
