Fresh-keeping technique of wild acinus

Abstract

The invention discloses a preserving method for wild berries. An edible gelatin substance is heated, melted and added into the berries; the berries are stirred to evenly suspend in the edible gelatin; the gelatin is cooled to solidify into a frizzed body around the berries; and the berries are packed in vacuum, wherein, the transport and storage temperature ranges from minus 20 DEG C to 30 DEG C. In the preserving method, the gelatin substrate forms elastic honeycomb walls around the berries after the solidification and the walls have relatively strong crumpling resistance capability; and the berries are kept in vacuum such that the preserving period can reach more than six months and the transport is convenient. According to the different packaging periods of the berries, the natural color and the smell of the berries in the period are packaged in the gelatin so as to effectively avoid the loss of taste when the berries are eaten, and the berries are hermetically kept so as to maximally guarantee the freshness of the berries. The preserving method is suited to package various berries that can be damaged easily and have unique smells. The preserving method is a good method for long-distance transporting and long-term storing the rare wild primary-taste berries.
