감귤과피(0.1, 0.5, 1, 2, 4 및 6%)를 함유하는 사과식초, 현미식초 및 감식초의 상온(2) 및 가열(10)에 따른 hesperidin과 naringin의 추출량을 조사함과 동시에 선태성 고혈압 쥐의 혈압에 미치는 영향을 조사하였다. 상온 및 가열추출의 경우 hesperidin과 naringin의 함량은 사고식초에 비하여 현미 및 감식초에서 높은 함량을 나타내었다. 상온추출 1일에서 hesperidin과 naringin의 추출이 완료
Effect of temperature(room temperature and boiling) and content of citrus peel(0.1∼6.0%) on the extractable hesperidin and naringin in the vinegars(apple, brown rice and persimmons) and also, dietary effect in hyperpiesia rats on blood pressure, biochemical changes were investigated. Extractable amounts of hesperidin and naringin in persimmons and brown rice vinegar were higher than those of apple vinegar in the both extraction of room temperature and boiling. Hesperidin and naringin contents showed highest in the one day extraction at room temperature when citrus peel was below 1% but, 3∼5 days extraction was optimum when the peel was above 2%. Hesperidin and naringin contents showed maximum at 2 hours extraction in case of boiling. Neutral lipids, total cholesterol and LDL cholesterol in blood, and blood pressure(reduction of 10.7∼33.2 mmHg) of the hyperpiesia rats took in 0.5% apple vinegar with 0.2, 0.4 and 0.6% citrus peel powder for 4 weeks were lower or reduced than those of control groups. But HDL cholesterol was higher than that of control groups.
