摘要
研究了海参制品中盐分测定方法。对比煮制法、沉淀蛋白法和灰化法3种方法处理样品后,再利用直接滴定法、间接滴定法和电位滴定法3种方法测定样品中的盐分。结果表明,灰化法制备试液具有操作简便、测量结果准确度高等优点;直接滴定法精密度满足试验需求,操作简便,适合海参制品的盐分测定。
This paper studies on the determination of salt content.It compares three preparations of test solution such as boiling,precipitation of protein and incineration,after that direct titration,reversed titration and potentiometric titration are analyzed.The results show that the preparation of test solution by incineration is convenient to operate and highly accurate. Direct titration is precise and convenient to operate,which is suitable for determination of salt content in sea cucumber product.
