현미 7.5%, 엿기름 1.5%, 홍삼 3%. 에탄올 6%를 재료로 동아를 7.5% 가한 것과 가하지 않은 것을 Acetobacter aceti 3281를 가해 25℃에서 150일간 초발효시켰다. 그 결과, 동아를 가하지 않은 식초는 총당3.3%, 환원당 1.5%, 단백질 11.S/280nm. 아미노산 2.7 μM/ml, 에탄을 0.5%, pH 3.0, 산도 4.59%, 유기산 함량5.2%를 나타냈다. 동아를 7.5%더 가해 만든 식초는 총당 2.3%, 환원당 1.1%. 단백질 10.8/280nm, 아미노산 2.1 μM/ml, 에탄올 1.2%, pH 3.1, 산도 4.61%, 유기산 함량 4.9%를 나타냈다. 5점만점 기호도 테스트에서 홍삼 식초는 3.86, 홍삼-동아 식초는 3.66을 나타냈다.

The 7.5% wax gourd-added mash composed of 7.5% brown rice, 1.5% malt, 3% red ginseng and 6% ethanol solution, and mash which 7.5% wax gourd was not added were fermented as vinegar and produced acetic acid, with the use of Acetobacter aceti 3281, at 25℃ for 150 days. As the result, vinegar of no added-wax gourd was shown containing 3.3 % total sugar, 1.5% reducing sugar, 11.5 absorbance at 280nm, 2.7μM/ml amino acid, and 0.5 % ethanol, 3.0 pH, 4.59% acidity, 5.2% organic acid. The 7.5% wax gourd-added vinegar showed 2.3% of total sugar, 1.1% reducing sugar, 10.8 absorbance at 280nm, 2.1 μM/ml amino acid, 1.2% ethanol, 3.1 pH, 4.61% acidity, 4.9% organic acid. In preference test of 5-points in full, red ginseng vinegar showed 3.86, and wax gourd-red ginseng vinegar 3.66.
