초록
This study’s purpose was to investigate the characteristics of a traditional Korean rice wine containing lactic acid bacteria (LAB), called makgeolli. The makgeolli was brewed with the alcohol-tolerant Pediococcus acidilactici strain K3, and was analyzed for LAB cell counts, alcoholic content, turbidity, pH, total acidity, amino nitrogen, total sugars, reducing sugars, solid contents, and organic acids. The physicochemical properties of the makgeolli were mostly maintained during fermentation (9 d) and storage (15 d). We also monitored the properties of LAB-supplemented commercial makgeollies, after adding P. acidilactici K3 at a concentration of 10⁷ CFU/ml makgeolli, for one month. Most of their properties, such as alcoholic content, turbidity, pH, total acidity, amino nitrogen, total sugars, reducing sugars, solid contents, and organic acids, were preserved during storage at 10oC, suggesting that makgeolli supplemented with live LAB can be produced. These results suggest that alcohol-tolerant P. acidilactici K3 can be used for makgeolli brewing either as a starter or as a supplement.
Abstract
This study’s purpose was to investigate the characteristics of a traditional Korean rice wine containing lactic acid bacteria (LAB), called makgeolli. The makgeolli was brewed with the alcohol-tolerant Pediococcus acidilactici strain K3, and was analyzed for LAB cell counts, alcoholic content, turbidity, pH, total acidity, amino nitrogen, total sugars, reducing sugars, solid contents, and organic acids. The physicochemical properties of the makgeolli were mostly maintained during fermentation (9 d) and storage (15 d). We also monitored the properties of LAB-supplemented commercial makgeollies, after adding P. acidilactici K3 at a concentration of 107 CFU/ml makgeolli, for one month. Most of their properties, such as alcoholic content, turbidity, pH, total acidity, amino nitrogen, total sugars, reducing sugars, solid contents, and organic acids, were preserved during storage at 10oC, suggesting that makgeolli supplemented with live LAB can be produced. These results suggest that alcohol-tolerant P. acidilactici K3 can be used for makgeolli brewing either as a starter or as a supplement.
