Features of the collection and storage of blueberries

Bilberry shoots and leaves are harvested during the flowering period of the plant and dried in a well-ventilated area. Berries are harvested ripe, always in dry weather.

The following methods are used to prepare for storage.

  • Drying. The berries are placed in a special dryer and kept at 40 °C until slightly dried. Then the temperature is increased to 70 °C and dried to such a state that the fruits do not get their hands dirty and do not stick together. Berries intended for drying should not be washed. Dried blueberries can be stored for up to two years.
  • Quick Freeze. Frozen berries retain their properties for 8-10 months.
  • Extraction of juice. The berries are crushed (ideally, rubbed with a wooden pestle). The mass is squeezed out by a press. A little water is added to the cake and the spin is repeated to maximize the extraction of colorants. Sugar (80 grams per 1 liter) is added to the resulting liquid, the mixture is heated to 80 °C, poured into a sterilized container and rolled up. Juice must be diluted with water before drinking.
  • Preparation of "raw jam". Washed blueberries are placed in a sterilized glass jar, poured in layers of sugar (700-800 grams per 1 kg of berries) and periodically shaken to compact. The container is sealed with a plastic lid. The product must be kept refrigerated.

Blueberries are also used to make jams, marmalades, marshmallows and other delicacies, but their preparation requires prolonged heating, which largely deprives the product of its beneficial properties.
