본 연구에서는 참다래 식초 개발을 위하여 초산발효 조건 및 올리고당 첨가에 따른 품질 특성을 조사하였다. 그 결과 초기알코올 농도 6%, 초기산도 1%에서 7일 동안 발효시켰을 때 총산이 가장 높게 나타났다. 올리고당 첨가에 따른 영향에서 총산은 올리고당 15% 첨가구에서 5.03%로 가장 높게 나타내었다. 참다래 식초의 유리당은 fructose, glucose 및 maltose가 확인되었으며 총 유리당은 올리고당 첨가량이 많을수록 높게 나타났다
This study was designed to investigate quality characteristics and conditions of acetic acid fermentation of kiwi vinegar following addition of oligosaccharide. During the acid fermentation alcohol concentration and total acidity were shown to be 6% and 1.0%, respectively, with the highest acetic acid yield. Acetic acid fermentation of kiwi following addition of oligosaccharide showed the highest acetic acid yield with 15% oligosaccharide. Free forms of sugars in kiwi vinegar were detected to be fructose, glucose and maltose. Organic acid of kiwi vinegar were malic, lactic, acetic, citric and succinic acid. Total content of organic acid was shown to be the highest with 15% oligosaccharide. Mineral content was shown to be lower when oligosaccharide amount was increased. In conclusion, oligosaccharide addition has an insignificant effect on acetic acid fermentation of kiwi, and was evaluated to be suitable at 15%.
