Abstract
The dropwort was fermented by steeping with brown sugar, fructose syrup or oligosaccharide at room temperature for 2 month, and then stored at cold room for 6 months. The dropwort extracts prepared with three different sugars showed more than $50^{\circ}$Brix, below pH 4.0 and about $0.7\%$ titratable acidity. The dropwort extract with brown sugar showed $1.6{\times}10^6$ viable cell counts and $21.2\%$ reducing sugar. Formation of $CO_2$ gas was superior to the dropwort fermented with brown sugar or oligosaccharide. The dropwort extract with fructose syrup indicated $9.0{\times}10^3$ viable cell counts and $50.1\%$ reducing sugar. Microorganism present in fermented dropwort extract was effectively pasteurized by the addition of $3\%$ citric acid and heat-treatment at $85^{\circ}C$ for 15 min, resulting in the less production of $CO_2$ gas. The dropwort extracts prepared with brownsugar, fructose syrup or oligosaccharide was suitable for the standardization that required for plant extract in Korea Food Codex.
