宁波市休闲食品中食品添加剂使用状况分析

目的:了解宁波市休闲食品中食品添加剂使用状况。方法:对2009年-2010年3类休闲食品的9类食品添加剂使用情况进行分析。结果:合格率最高为糖果类(100%),其次是膨化食品类(92.2%),最低为蜜饯凉果类(48.1%)。不合格原因主要存在防腐剂和甜味剂的使用上。其中二氧化硫残留量是超标的最重要原因,其他分别是甜蜜素、苯甲酸、糖精钠、安赛蜜、胭脂红。结论:建议食品监管部门加强对休闲食品的食品添加剂过量、超范围使用管理。     

论新形势下的食品添加剂安全管理

近年来,源于食品添加剂滥用或非法添加化学物的食品安全事件不断出现,引起了广大人群对食品安全的担忧。应当在正确认识食品添加剂的基础上,采取积极对策,包括开展食品安全风险监测和风险评估、建立统一的食品安全标准体系、加强事前防范、强化源头管理、规范新闻媒体报道等。     

2006年-2008年广州市部分食品添加剂监测结果分析

目的:了解广州市部分食品食品添加剂使用现状。方法:2006年-2008年广州市对来源于所辖12个区县的肉菜市场、超市、餐饮店、批发点和零售点等的酱菜、蜜饯凉果、饮料、熟肉制品等食品进行食品污染物及部分食品添加剂按国家标准方法进行检测。结果:酱菜、蜜饯中的苯甲酸超标率分别为11.4%和6.3%;蜜饯、熟肉制品中的山梨酸超标率分别为6.3%和0.3%;蜜饯中的二氧化硫残留超标率为5.5%;熟肉制品中的亚硝酸盐超标率为0.3%;蜜饯、酱菜中的糖精钠超标率分别为17.2%和5.7%;蜜饯、饮料中的甜蜜素超标率分别为49.6%和20.0%;蜜饯中的安赛蜜、胭脂红、柠檬黄和日落黄的超标率分别为1.8%、3.2%、2.5%和1.6%。结论:广州市部分食品的食品添加剂过量、超范围使用问题应引起相关监督监管部门重视。     

高效液相色谱同时测定食品中5种添加剂

[目的]建立高效液相色谱(HPLC)同时测定食品中安赛蜜、糖精钠、苯甲酸、山梨酸和阿斯巴甜的方法。[方法]样品经去蛋白、脱色、超声提取、过滤膜等预处理,采用HPLC二极管分段多波长同时测定。[结果]方法线性良好,相关系数为0.9995~0.9999,回收率为90.70%~98.20%,相对标准偏差为0.41%~2.40%。[结论]方法准确可靠、简便快速、易于掌握、便于推广。     

Evaluation of certain food additives and contaminants

This report represents the conclusions of a Joint FAO/WHO Expert Committee convened to evaluate the safety of various food additives, with a view to recommending acceptable daily intakes (ADIs) and to preparing specifications for identity and purity. The Committee also evaluated the risk posed by two food contaminants, with the aim of deriving tolerable intakes where appropriate and advising on risk management options for the purpose of public health protection. The first part of the report contains a general discussion of the principles governing the toxicological evaluation of and assessment of dietary exposure to food additives and contaminants. A summary follows of the Committee's evaluations of technical, toxicological and dietary exposure data for certain food additives (aluminium-containing food additives, Benzoe Tonkinensis, glycerol ester of gum rosin, glycerol ester of tall oil rosin, glycerol ester of wood rosin, octenyl succinic acid modified gum arabic, polydimethyl siloxane, Ponceau 4R, pullulan, pullulanase from Bacillus deromificans expressed in Bacillus licheniformis, Quinoline Yellow and Sunset Yellow FCF) and two food contaminants (cyanogenic glycosides and fumonisins). Specifications for the following food additives were revised: aluminium lakes of colouring matters; beta-apo-8'-carotenal; beta-apo-8'-carotenoic acid ethyl ester; beta-carotene, synthetic; hydroxypropyl methyl cellulose; magnesium silicate, synthetic; modified starches; nitrous oxide; sodium carboxymethyl cellulose; and sucrose monoesters of lauric, palmitic or stearic acid. Annexed to the report are tables summarizing the Committee's recommendations for dietary exposures to and toxicological evaluations of the food additives and contaminants considered.
