【摘要】 由于水产品中甲醛有本底含量,利用乙酰丙酮分光光度法测定泥螺在不同浸泡时间下的甲醛含量,结果表明:泥螺内甲醛含量随着浸泡时间延长而逐渐降低。浸泡的同时加干茶叶渣吸附甲醛,加快了甲醛浓度下降。实验结果显示:泥螺食用前需要通过4~5h以上的浸泡,而且要多次换浸泡水。更多还原

【Abstract】 Because of formaldehyde in aquatic products have intrinsic content,using acetyl acetone spectrophotography method for the determination of Bullacta exarata in different soaking time of formaldehyde content,The results showed that: in the formaldehyde content of Bullacta exarata with immersion time gradually decreased.Immersion and dry tea leaves the adsorption of formaldehyde,formaldehyde concentration decreased speed.The experimental results show: Bullacta exarata before eating through 4~5h above the immersion,but many times for the soaking water.更多还原
