Abstract

The invention discloses a bio-fermentation onion skin extractum and a production method thereof. The production method is characterized by comprising the following steps of: mixing 87 to 96 weight percent of onion skin powder, 2 to 5 weight percent of lactic acid bacteria fermenting agent and 2 to 8 weight percent of yeast fermenting agent; standing and culturing the mixture with water moisture of between 60 and 65 percent at temperature of between 33 and 36 DEG C for 10 to 18 hours to obtain fermented onion skin powder; heating the fermented onion skin powder to temperature of between 60 and 100 DEG C, refluxing, extracting, filtering, reducing pressure, drying and smashing, thus obtaining the bio-fermentation onion skin extractum. The bio-fermentation onion skin extractum produced by using the method is applicable to patients with hypertension, hyperlipidemia and diabetes mellitus and can be used as burdening of foods, such as bread, desserts, beverage and the like; the onion skin extractum is fermented by probiotic bacteria, so active ingredients of onion skin can be promoted, the quality of the product is improved, and the resource utilization rate is increased effectively; and the product with extremely high application value can be obtained, the environmental pollution is avoided, the cost is reduced and the resources are saved.
