摘要
人造奶油酸价和过氧化值的准确测定一直是研究热点。本文基于最新的标准,采用先进的自动电位滴定仪,研究存储条件对人造奶油酸价和过氧化值的影响。结果表明,存放时间、温度、光线、容器材质对样品的酸价和过氧化值的影响较大。随着存放时间的延长、温度的升高,酸价和过氧化值变大;光线强度和存储容器对结果有相应的影响。
The accurate determination of the acid value and peroxide value of margarine has been a research hotspot.Based on the latest standards,an advanced automatic potentiometric titrator was used to study the effect of storage conditions on the acid value and peroxide value of margarine. The results showed that the storage time,temperature,light and container material had a great influence on the acid value and peroxide value of the sample. As the storage time increased and the temperature increased,the acid value and the peroxide value became larger. The light intensity and the storage container had a corresponding influence on the result.
