FIELD: food industry.SUBSTANCE: invention relates to a technology for processing berries. Blueberries are prepared. One performs convective drying till intermediate moisture content, additional drying in microwave field till dry substances content is equal to no less than 85%, impregnation with liquid carbon dioxide with simultaneous pressure boost. Pressure is reduced down to atmospheric value with simultaneous freezing of carbon dioxide. Carbon dioxide is sublimed with simultaneous swelling of blueberries. One performs packaging into a package fabricated of a polymer or combined material in an oxygen-free medium.EFFECT: method allows to reduce losses of biologically active substances of initial raw materials. |
