Storing Homemade Whey

How to make whey

Whey can be made from fermented milk, kefir, curdled milk, fermented baked milk or yogurt.

To make whey, pour raw milk into a clean glass jar. Cover the jar with a lid (coffee filter or clean cotton cloth) and leave it at room temperature for 2-3 days until it sours. To speed up the process, you can add a little lemon juice. Then the milk will sour overnight.

Pour the sour milk into a suitable pan (not aluminum) and place on the lowest heat. Heat gradually without letting it boil. Otherwise, the cottage cheese will be very hard, like rubber.

You will know about the formation of curd by the separation of whey and the formation of a curd mass.

To separate it, place a colander on another pan and cover it with gauze. Drain the curd.

Take the gauze and twist the edges. Hang it up with a container into which the whey will drain. As soon as liquid stops dripping from the curd, put it in the refrigerator and pour the whey into a jar or pan.

How to store whey in the refrigerator

When you buy whey in a store, always pay attention to the production date.

A quality product without preservatives should have a shelf life of a maximum of 72 hours (3 days) and should not contain any foreign ingredients. The shelf life of the serum in the refrigerator in a closed bag expires on the date specified by the manufacturer. If you missed it and the product becomes stitched, it can be used for cosmetic purposes.

How to store homemade whey

Many housewives prepare this product themselves. It remains after making homemade cheese. The question arises: how and where to store the whey from cottage cheese?

In the absence of a refrigerator, the best place to preserve the quality and nutritional properties of the product is the cellar. Optimal conditions are observed here - humidity and temperature, there is no sunlight, which is important to avoid fermentation processes. The length of time to store homemade whey in the cellar is up to 3-4 days.

If this is not possible, then whey can be stored on the balcony, at an air temperature no higher than 10°C, but not lower than zero. To do this, pour it into a clean, opaque container and leave for up to 3 days.

At room temperature, the product spoils quickly, but there is a way to keep it fresh a little longer. To do this, cover the whey with clean gauze so that it sinks into the liquid. Moisture will evaporate from the fabric and thereby cool the contents.

The length of time the curd whey is stored in this way at room temperature is up to 2 days away from direct sunlight. It is best to take the container to the pantry.

In the refrigerator, on the middle shelf, the homemade product will be usable for 3-4 days.

Is it possible to freeze whey?

When naturally made fermented milk products are stored, vitamin C accumulates in them, which makes them beneficial for digestion. At temperatures below 0°C, beneficial substances and vitamins are destroyed, and the product becomes useful. However, you can freeze the whey. The main thing is not to do this in a glass container, as it will burst when frozen. A plastic bottle (you can fill it no more than 4/5 full) or ice cube trays is best. When the product is frozen, you can pour the finished cubes into a bag and store in the freezer for up to 6 months.
