The aim of this research was to analyze makgeolli with nineteen kinds of rice and koji. Among 19 rice, 18 rice were domestic products and one rice was an import. For the properties of koji made with 19 kinds of rice, the acidity was over 5.0 and the saccharogenic power was more than 60SP. Makgeolli brewed with 19 kinds of rice and the koji of each rice were analyzed for alcohol contents, pH, total acidity and solid contents during fermentation. After fermentation, raw liquor's alcohol degree was set 6.0%, the pH ranged 3.47-3.76, the total acidity 0.27-0.44%, the solid contents and the reducing sugar were 2.7-4.6 o Bx and 2.49-6.01 mg/mL. Organic acid was detected 5 kinds (oxalic, malic, lactic, acetic, succinic acid) and free sugars were found such as glucose, maltose and fructose. Hwayoung, Hopum and Sura were higher than the residue in 15 kinds of rice in the preference test.
: For development of new high-value Korean traditional fermented food by using bioactive fungi and bacteria, Nuruk, Makgeolli and Cheonggukjang were prepared by mold, yeasts and bacteria from Korean traditional fermented foods and their physiological functionalities were investigated. Aspergillus oryzae N152-1 Nuruk showed the highest antihypertensive angiotensin I-converting enzyme inhibitory activity(57.2%), and Makgeolli made by Saccharomyces cerevisiae Y111-5 and commercial JS Ipguk (solid cultures of saccharifying enzyme-producing mold) was showed 42.0% of anti-obesity α-glucosidase inhibitory activity. Among various Cheonggukjang, No 463 Cheonggukjang made by Brevibacterium iodinum NCDO 613(T) was showed the highest fibrinolytic activity (size of clear zone: 28 mm) and good anti-obesity α-glucosidase inhibitory activity.
The objective of this study was to analyze proximate composition and physicochemical properties according to different kinds of rice. In total, 20 varieties of rice were used (Domestic-19, Imported-1). The moisture contents ranged from 11.11±0.20 to 3.28±0.03%. The crude protein and crude lipid contents were ranged from 5.04±0.03 to 7.02±0.10% and 0.18±0.01 to 0.73±0.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
