Method of preparing black platycodon concentrate enhanced saponin contents platycodon extract and liquid stick comprising the same

摘要

The present invention relates to a method for producing black bellflower in which the content of saponin, such as Platicodin, is remarkably increased through a number of times of steaming, aging and drying processes with a natural plant fermented fermented and dried bellflower, and a black bellflower extract including the same. And it relates to a liquid stick manufacturing method. In the present invention, the content of absorbable saponin metabolites (saponin metabolites, saponin intermediate metabolites, specific saponins) is increased through immersion and penetration using natural plant fermented fermented liquid, steam steaming, hot air drying, maturation and low temperature drying steps. It is significantly higher than dried bellflower, significantly lowers the content of harmful substances (residual pesticides, heavy metals and benzopyrene, etc.) can
