| 摘 要： | 梅菜属于腌菜的一种,口感好、营养价值高,作为一种家常菜常出现在寻常百姓的饭桌上.水源、土壤和空气中SO2含量超标,添加硫含量超标的添加剂或使用硫含量超标的化肥等均会导致梅菜硫含量超标.市售梅菜硫含量是否超标已经成为广大梅菜食用爱好者和有关质量管理部门重点关注的问题之一.为了保障广大梅菜食用爱好者的利益与健康,质量管理部门和梅菜生产产家迫切需要一种快速、便捷的检测梅菜硫含量的工艺.本文采用硝酸-高氯酸消化法及硫酸钡比浊法对市售5种梅菜的硫含量进行检测,检测结果分别为9.09 mg/g、3.94 mg/g、3.85 mg/g、3.50 mg/g、3.51 mg/g.

| Abstract: | Meigancai is a kind of pickles,with good taste high nutritional value.It has become a kind of Home Dishes.Howvever,the environmental pollution becomes more and more serious.in the water,as soil and air SO2 content exceeds bid may lead to the planting Meigancai sulfur content exceing the standard.Meanwhile,in order to extend the shelf life of the mei dried vegetables、increase production or improve the taste of the mei dried vegetables,etc,in the production process some illegal businessmen added additives which sulfur content exceeds bid or using the sulfur content excessive amounts of fertilizer lead to the Meigancai sulfur content exceeds bid.Whether the comercially available Meigancai contain excessive levels of sulphur content or not has aroused lots of Meigancai lovers and Quality Control Department＇s considerable concern.In order to protect the people＇s health,a rapid and convenient sulphur content detection process of the Meigancai is quality management department and Meigancai manufacturers is needed.In this paper,using nitric acid and perchloric acid digestion and Barium Sulfate Turbidimetry to determination of 5 kinds of Meigancai sulfur content of commercially available.The detection results are 9.09 mg /g,3.94 mg /g,3.84 mg /g,3.49 mg /g,3.51 mg /g respectively. |
