Abstract

Liquid yoghurts were made with ginseng extract, white ginseng powder and tail ginseng powder, which have pharmacological effects and are palatable by Korean. The acidity, number of lactic acid bacteria and viscosity of yoghurts were examined and taste, flavor and characteristics of preservation of yoghurts were also tested. The results obtained were summarized as follows; l. The acidity of yoghurt was high for ginseng yoghurts, especially tail ginseng yoghurt(1.15%) was higher than that of control yoghurt(0.76%). 2. The number of lactic acid bacteria in yoghurt was higher for ginseng yoghurt than that of control yoghurt($1.5{\times}10^8/m{\ell}$), especially tail ginseng yoghurt($4.3{\times}10^8/m{\ell}$) showed the highest number of lactic acid bacteria. 3. The viscosity of yoghurt was high for ginseng yoghurt, especially white ginseng powder yoghurt was higher than that of control. 4. The score of yoghurts for tastes, flavor and overall acceptability were higher for tail ginseng yoghurt than those of control yoghurt. 5. When yoghurts were stored at $5^{\circ}C$ for 10 days, the pH, acidity, number of lactic acid bacteria of all yoghurt were not changed significantly.

한국인의 기호에 맞으며 약리적인 효능을 가지고 있는 인삼을 인삼 extract, 백삼분 및 미삼분 형태로 요구르트 제조시에 첨가하여 요구르트의 산생성도, 유산균수, 제품의 점도, 관능검사 및 보존성 등을 시험한 결과는 다음과 같다. 1. 인삼 extract, 백삼분 및 미삼분을 첨가한 액상 요구르트의 시험제조 결과 산도에 있어서는 무첨가구의 0.76%에 비하여 첨가구 특히 미삼첨가구가 1.15%로서 가장 높았다. 2. 유산균수는 무첨가구의 $1.5{\times}10^8/m{\ell}$에 비하여 첨가구가 더 증식되었고 특히 미삼첨가구가 $4.3{\times}10^8/m{\ell}$로서 가장 높았다. 3. 제품의 점도에 있어서는 무첨가구에 비하여 인삼첨가구 특히 백삼첨가구가 높았다. 4. 액상요구르트의 관능검사 결과 무첨가구에 비하여 맛, 향취 및 전체적인 기호도에서 미삼이 가장 높았다. 5. 요구르트 제품의 $5^{\circ}C$, 10일간 보존시험에서 pH, 산도 및 유산균수는 큰 변화가 없었다.
