A new method for manufacturing the active seed starter (Korean Kok-Ja) has been studied, designed new method consists of the boiling process of raw wheat material and pure culture process of Rhizopus fungi. The feasibility study for industrialization of these methods have been performed, the liquefying and saccharifying activities were put to analysis and compared with conventional product of Kok-Ja. The isolated strains of mold from raw wht and Kok-Ja were idetified as Rhizopus sp., Aspergillus sp., Aspergillus niger sp., Endomyces sp., and Fungi imperfecii. It is proved that the saccharifying and liquefying activities are much stronger than that of conventional product of Kok-Ja, and the growth of Rhizopus strain in boild what material are vigorous than that of old type Kok-Ja. Then it is considered the newly designed method is effective to manufacturing a fine better Kok-Ja.
