玩转二维码 点阵码技术分析

正在工业4.0及互联网+时代,产品防伪溯源是大势所趋,国家、行业、印刷和防伪企业以及品牌商纷纷筹建自己的防伪溯源系统。在防伪溯源系统中众多跟踪技术之中,条码作为连接消费者和溯源信息的入口技术,被广泛应用。常见的条码按维数可分为一维条码(常见的中国药监码CODE128C、商品条形码EAN码);二维条码(常     

实施食品安全追溯 助推食品安全监管

GSI崂山绿茶追溯系统目前已在青岛涵雪饮品有限公司正式运行使用。今年涵雪绿茶的外包装上都有了一组唯一的溯源码。消费者登陆青岛市技术监督科技信息所的网站就可以凭借溯源码查询到产品名称、条码号、包装规格、生产许可证号等11项产品基本信息;种植的地理位置、种植环境日照时长、土壤酸碱度、降雨量等影响茶叶品质的19项产品质量信息以及产品的检测报告等。同时网站还提供累计查询次数,这一项的设置可以起到防伪的作用。通过这一串数字,消费者就可以全面了解所购买茶制品的各项信息。     

基因芯片+区块链的高端茶叶可追溯平台

茶叶市场监管力度低,溯源保真难,导致市场茶叶品质参差不齐。传统的溯源体系在茶叶生产的全过程中,很难避免溯源信息篡改、真假茶叶替换、防伪签套用、转卖等造假问题。针对这些问题,团队设计集生物技术与区块链技术相结合的溯源方式,在茶叶生产的各个过程中对茶叶进行基因抽样检测,再将检测信息上传至区块链,保证信息无误。采用的基因芯片技术和区块链技术,从基因层面确保茶叶的高品质,从技术层面确保了溯源信息的真实性,切实保障消费者对茶叶相关过程信息的知情权。     

电码电话防伪包装设计

电码电话防伪包装是一种防伪网络系统,也是一种封闭型防伪链。也就是产品出厂进入流通环节后,最终到达消费者手中,而消费者又可通过有关信息(包装的”明码”与“暗码”)查询到产品(商品)的原始“档案”凭据,从而得知所购商品的真伪。这种防伪包装系统将厂家、经销商(流通)、消费者连成一个封闭的循环链。 一、原理 电码电话防伪根据存档式二元防伪原理、利用电脑及现代电讯     

RFID电子标签在服装产品防伪溯源中的应用

RFID电子标签,又称无线射频识别电子标签。识别装置与被植入RFID电子标签的物品接近时,识别装置通过无线电讯号识别RFID标签写入的物品信息并读写相关数据,自动地获取被识别物品的相关信息,并提供给后台计算机处理系统来完成相关信息处理。本文通过介绍与第三方检验机构(中纺标公司CTTC)在纺织服装领域利用先进信息技术进行防伪溯源的科技研究项目,研究了如何利用RFID电子标签植入服装产品,使企业和消费者通过读取RFID电子标签数据来辨别品牌服装真伪,起到防伪溯源的作用。

进口燕窝溯源系统的构建和应用

随着食品贸易全球化和供应链的复杂化,监管全球食品供应链无疑是一项艰巨挑战。目前,一种由政府监管部门参与监督、各食品企业参与配合的第三方溯源服务系统,已逐渐成为监管制度的有效补充。基于我国与马来西亚、印度尼西亚等燕窝原产国输华燕窝双边议定书的签订,以及境外燕窝加工企业卫生注册工作的开展,中国检验检疫科学研究院(Chinese Academy of Inspection and Quarantine,CAIQ)开发了燕窝溯源管理服务平台,为获华注册的境外燕窝加工企业的输华燕窝提供溯源服务,输华燕窝的最小销售包装上均加贴CAIQ溯源标签,我国消费者可通过扫描溯源标签上的二维码或通过网站查询16位燕窝码,获得燕窝产品的燕屋、加工、出口、进口、经销各环节的全程追溯信息,为消费者识别和选购合法进口燕窝提供有效途径。CAIQ溯源系统是建立在进口注册和口岸检验检疫基础上的追溯系统,是搭载了质量信息的追溯系统。

Reliable identification of grapevine rootstock varieties using RAPD PCR on woody samples

Since grapevine ( Vitis spp .) rootstock material is being traded increasingly as disbudded woody material a lack of distinctive morphological features on such material necessitates an alternative and reliable means of identification. Methods described here were developed for rapid and efficient extraction of DNA from woody samples rich in phenolic compounds and polysaccharides, and for subsequent identification of varieties by RAPD PCR. Using these methods, and with the application of only one selected RAPD primer, we were able to differentiate sixteen rootstock varieties, including the seven varieties most commonly used in Germany. Problems commonly encountered with reproducibility of RAPD patterns were avoided by choosing primers with a dinucleotide sequence and a high G/C content that allowed a rather high annealing temperature of 45°C. Methods described here should also be useful for other horticultural crops, especially those with woody tissues rich in phenolic compounds and polysaccharides.     

Aroma characterization of various apricot varieties using headspace–solid phase microextraction combined with gas chromatography–mass spectrometry and gas chromatography–olfactometry

The characterization of the aromatic profile of several apricot cultivars with molecular tracers in order to obtain objective data concerning the aromatic quality of this fruit was undertaken using headspace–solid phase microextraction (HS–SPME). Six apricot cultivars were selected according to their organoleptic characteristics: Iranien, Orangered, Goldrich, Hargrand, Rouge du Roussillon and A4025. The aromatic intensity of these varieties measured by HS–SPME–Olfactometry were defined and classified according to the presence and the intensity of grassy, fruity and apricot like notes. In the six varieties, 23 common volatile compounds were identified by HS–SPME–GC–MS. Finally, 10 compounds, ethyl acetate, hexyl acetate, limonene, β-cyclocitral, γ-decalactone, 6-methyl-5-hepten-2-one, linalool, β-ionone, menthone and (E)-hexen-2-al were recognized by HS–SPME–GC–O as responsible of the aromatic notes involved in apricot aroma and considered as molecular tracers of apricot aromatic quality which could be utilized to discriminate apricot varieties.     

Tests of potential functional barriers for laminated multilayer food packages. Part I: Low molecular weight permeants

The advent of the functional barrier concept in food packaging has brought with it a requirement for fast tests of permeation through potential barrier materials. In such tests it would be convenient for both foodstuffs and materials below the functional barrier (sub-barrier materials) to be represented by standard simulants. By means of inverse gas chromatography, liquid paraffin spiked with appropriate permeants was considered as a potential simulant of sub-barrier materials based on polypropylene (PP) or similar polyolefins. Experiments were performed to characterize the kinetics of the permeation of low molecular weight model permeants (octene, toluene and isopropanol) from liquid paraffin, through a surrogate potential functional barrier (25 μm-thick oriented PP) into the food simulants olive oil and 3% (w/v) acetic acid. These permeation results were interpreted in terms of three permeation kinetic models regarding the solubility of a particular model permeant in the post-barrier medium (i.e. the food simulant). The results obtained justify the development and evaluation of liquid sub-barrier simulants that would allow flexible yet rigorous testing of new laminated multilayer packaging materials.

The development of reference materials for paralytic shellfish poisoning toxins in lyophilized mussel. II: Certification study

This paper describes the second part of a project undertaken to develop certified mussel reference materials for paralytic shellfish poisoning toxins. In the first part two interlaboratory studies were undertaken to investigate the performance of the analytical methodology for several PSP toxins, in particular saxitoxin and decarbamoyl-saxitoxin in lyophilized mussels, and to set criteria for the acceptance of results to be applied during the certification exercise. Fifteen laboratories participated in this certification study and were asked to measure saxitoxin and decarbamoyl-saxitoxin in rehydrated lyophilized mussel material and in a saxitoxin-enriched mussel material. The participants were allowed to use a method of their choice but with an extraction procedure to be strictly followed. The study included extra experiments to verify the detection limits for both saxitoxin and decarbamoyl-saxitoxin. Most participants (13 of 15) were able to meet all the criteria set for the certification study. Results for saxitoxin.2HCl yielded a certified mass fraction of <0.07 mg/kg in the rehydrated lyophilized mussels. Results obtained for decarbamoyl-saxitoxin.2HCl yielded a certified mass fraction of 1.59+/-0.20 mg/kg. The results for saxitoxin.2HCl in enriched blank mussel yielded a certified mass fraction of 0.48 +/- 0.06 mg/kg. These certified reference materials for paralytic shellfish poisoning toxins in lyophilized mussel material are the first available for laboratories to test their method for accuracy and performance.
