摘要 为了了解桐乡市市售榨菜中食品添加剂的使用情况,为监测榨菜中的添加剂水平、指导合理有效监管添加剂的使用、民众日常的选择采购提供依据。本实验依据相应的国家标准,对榨菜中的安赛蜜、糖精钠、苯甲酸、山梨酸进行测定和评价。经检测,在桐乡市的超市、农贸市场采集样品90份,合格84份,其中包装榨菜72份,散装榨菜18份,合格率为93。3%,存在散装榨菜中添加剂含量普遍高于包装榨菜的现象。桐乡市市售榨菜的添加剂使用情况总体上是符合国家标准的,但散装榨菜中的使用量普遍偏高,监管部门应着重加强对散装榨菜的质量监管,防范于未然,保证消费者的健康。88943
To understand the use of food additives in Tongxiang City, and to provide the basis for monitoring the level of additives, guiding the rational and effective supervision of the use of additives, people's daily procurement。 This experiment is based on the corresponding national standards, the content of acesulfame, saccharin sodium, benzoic acid and sorbic acid in pickled mustard tuber were determined and evaluated。 After testing,90 samples were collected from supermarkets and farm product market in Tongxiang City, qualified 90, of which 72 copies of packing pickled mustard tuber, and 18 copies of bulk pickled mustard tuber, the qualified rate is 93。3%, and the level of additives in bulk pickled mustard tuber is generally higher。 Additives sold in Tongxiang city the use of pickled mustard tuber is generally in line with national standards, but the amount is generally high in bulk pickled mustard tuber, regulators should focus on strengthening the quality supervision of bulk pickled mustard tuber, preventive measures, to ensure the health of consumers。

榨菜通常指的是腌制榨菜,它是优良茎用芥菜经腌制压榨加工后的半干态非发酵性咸菜。榨菜的质地脆嫩爽口,风味鲜美,营养丰富,具有特殊的风味,具有特殊酸味和咸鲜味,富含人体所必需的蛋白质、胡萝卜素、膳食纤维和矿物质等营养元素,以及谷氨酸、天门冬氨酸等17种游离氨基酸。因而榨菜深受人们的喜爱,是十分常见的佐餐食品。在榨菜的加工生产过程中,由于工艺和风味的需要,往往会加入不少的食品添加剂,其中,苯甲酸、山梨酸、糖精钠、安赛蜜是较为常用的四种食品添加剂。论文网 高效液相色谱法监测市售榨菜4种食品添加剂:http://www.youerw.com/shiping/lunwen_172388.html
