Fermentation and Sensory Characteristics of Korean Traditional Fermented Liquor (Makgeolli) Added with Citron (Citrus junos SIEB ex TANAKA) Juice
This study was performed to examine the physicochemical characteristics of Korean traditional fermented liquor added with citron juice and the levels (3, 6 and 9%) of citron (Citrus junos) juice during two-step-brewing. The pH of traditional Korean fermented liquor added with citron juice increased after 3 days of fermentation and then the pH values decreased from the sixth day. pH increased again at the end of fermentation. Total acidity increased after 5 days of fermentation until the sixth day, then decreased rapidly but increased slightly up to 12 days. Alcohol content increased to 12.76-14.32% after 12 days of fermentation. As the amount of added citron juice increased, alcohol content decreased. Amino acids increased after 12 days of fermentation. A sensory evaluation appearance, flavor, sourness, sweetness, bitterness and overall acceptance of Korean traditional fermented liquor added with 6% citron showed higher values than those of the control.
