摘 要：
应用自动电位滴定仪的等量等当点滴定法,测定苹果、葡萄、草莓三类水果样品的可滴定酸。结果表明加标回收率为92.85%～96.65%,相对标准偏差为0.64%～1.84%,不受浸提液的颜色影响,准确度和精密度高,可以在水果品质测定中推广。

摘 要：
The determination of titratable acidity in apple,grape,strawberry was conducted by monotonic titration(MET) using automatic potentiometric titrator.The recovery and relative standard deviation(RSD) of the method are 92.85% to 96.65% and 0.64% to 1.84% respectively.The determination result is not affected by the color of sample,and the accuracy and precision are high.This method can be used in the determination of fruit quality.
