利用丙二醛与硫代巴比妥酸在高温和酸性条件下能发生缩合反应生成粉红色产物三甲川来测定鸭油中酸败产生的丙二醛。本方法的加标回收率为87．0％～93．2％，检出限为0．02 mg/kg，可用于鸭油中丙二醛含量的测定。
利用丙二醛與硫代巴比妥痠在高溫和痠性條件下能髮生縮閤反應生成粉紅色產物三甲川來測定鴨油中痠敗產生的丙二醛。本方法的加標迴收率為87．0％～93．2％，檢齣限為0．02 mg/kg，可用于鴨油中丙二醛含量的測定。
이용병이철여류대파비타산재고온화산성조건하능발생축합반응생성분홍색산물삼갑천래측정압유중산패산생적병이철。본방법적가표회수솔위87．0％～93．2％，검출한위0．02 mg/kg，가용우압유중병이철함량적측정。
Under high temperature and acidic conditions , malondialdehyde and thiobarbituric acid could react to form a pink compound 3,5,5’ -three methyl oxazole -2,4-diketone.Based on this reaction, a method was established to determine malondialdehyde content in duck oil by colorimetry .The recovery of this method was 87.0%~93.2%, and the detection limit was 0.02 mg/kg.
