| 摘 要： | 目的利用正丁醇常数法快速测定煎炸油脂中羰基价。方法 采用正丁醇为提取溶剂对煎炸油脂进行羰基价测定,用比色法测得吸光度值,通过吸光度常数直接算出羰基价。结果正丁醇常数法比现有国标方法更安全、简便,方法添加回收率为88%~127%,相对标准偏差为1.92%~9.82%。结论 该法快速、简便、精密度和准确度高,适用于煎炸油脂中羰基价的测定。

| Abstract: | Objective To determine carbonyl value in frying oils quickly and safely, Method A 1-butanol constant method was developed, 1-butanol was used as solvent to replace benzene, converted colorimetric absorbance into carbonyl value directly by measuring constant formula. Results The recovery rates of carbonyl compound were 88% to 127%, and the relative standard deviation were 1.92% to 9.82%. Conclusion Compared with the national standard method, this method is rapid, simple, precise and accurate, which is suitable for the determination of carbonyl value in frying oils. |
