Abstract:
The present invention relates to a method for increasing biomass of ginseng adventitious roots, including a step of cultivating ginseng adventitious roots by irradiating the ginseng adventitious roots with red light with a wavelength of 625 to 630 nm from a light emitting diode (LED). Using the irradiation of a specific wavelength by the LED according to the present invention, provided is a method for mass production of ginseng adventitious roots, which achieves the increase of biomass as well as the development and growth of favorable ginseng adventitious roots by developing a most proliferous condition for cultivating ginseng adventitious roots in bioreactors, and thus industrializes the mass production of ginseng adventitious roots in bioreactors. Accordingly, high value-added ginseng can be produced all the year around without being affected by the conditions of climate or surroundings and offered to various consumer groups at affordable prices.
Abstract:
The present invention relates to a composition for improving antioxidant activity or growth of a plant comprising a lacquer tree extract as an effective component. The lacquer tree extract of the present invention can be safely supplied to a consumer as urushiol which is a toxic material causing allergy is removed, promotes initial rearing of the plant, increases expression of genes related to salt resistance and drought resistance, pathogen, wound, and stress, and promotes antioxidant activity. Accordingly, the lacquer tree extract of the present invention is safe to a user, and can be industrially used as a biofertilizer for improving antioxidant activity or growth to agricultural crops.
Abstract:
The present invention relates to a method for producing an ultrafine powder of cultured wild ginseng roots having reduced water absorption index (WAI) or swelling power (SW) and increased water solubility index (WSI) and particular ginsenoside content, wherein the method comprising a step of grinding cultured wild ginseng roots using a low-temperature ultrafine grinder; to an ultrafine powder of cultured wild ginseng roots having reduced water absorption index (WAI) or swelling power (SW) and increased water solubility index (WSI) and particular ginsenoside content; and to a food and a beverage containing the ultrafine powder of cultured wild ginseng roots. The ultrafine powder of cultured wild ginseng roots produced using a low-temperature grinder according to the present invention has a significantly reduced particle size, thereby changing the structure of the cultured wild ginseng roots and increasing the surface area thereof, and thus improving the texture feeling and increasing availability and absorptivity in the body. Therefore, processed products manufactured from the ultrafine powder of cultured wild ginseng roots allow active ingredients to be easily digested and absorbed into the body, contributing greatly to the health food industry using ginseng.
