现行食品抽检工作中重复抽检的原因分析及建议

食品安全监督抽检是保障我国食品安全监管工作的重要一环,许多地市都将食品检验量及问题发现率作为政府对食品安全工作的考核指标。随着食品监管力度的增强和品牌经销商逐步占领市场,各终端经营场所销售的食品大致相同,这就使随机开展的食品安全监督抽检重复抽检现象客观存在。本文根据我国现行食品安全监督抽检现状,尝试从不同业态,不同抽检机构,样品差异性,抽样人员主观因素等方面分析造成重复抽检的原因,就如何保证抽样的代表性、减少重复抽检问题提出:加强科学制定计划,使用抽检APP共享抽样信息、限制重复数据,分任务制定检验项目,加强过程监管丰富样品来源,引入监督机制等相关建议。以期为避免重复抽检浪费经费,提高问题发现率和制定食品安全抽样工作规范提供参考。     

食品抽样工作现存问题及解决建议

食品安全抽检的目的是保障食品安全、公众生命安全,加强食品抽检工作对提升食品安全非常重要。抽样工作是食品安全抽检的首要环节,抽样的规范性、科学性、代表性直接影响问题发现率。本文首先以相关食品法律法规为依据,对抽样机构提出四点工作要求,分别是抽样制度要求、抽样前准备要求、抽样过程要求、样品交接要求。其次从抽检机构角度,总结实际工作问题,从抽检机构,和监管部门的角度分别给出解决建议,希望对提升抽样工作质量提供帮助。

针对加强食品检验检测质量控制的研究

民以食为天,食品安全始终是我国政府和人民重点关注的问题之一。自从我国进入新时代以来,国民经济水平有了显著提升,人们生活质量有了明显的改善,对吃穿住行的需求也越来越高,尤其是在食品方面,人们不再满足于吃饱,而是要吃的更好、更安全。因此,相关人员要重视食品检验检测质量控制工作,提升食品安全质量,让人们吃得更放心、更安心。就我国食品检验检测质量控制工作的现状来看,目前仍然存在很多缺陷和问题,无法满足现阶段人们对食品安全卫生的需求。所以,相关人员必须提升食品检验检测质量控制水准。提升控制水平,保证检验工作效率,更好地为食品行业服务。     

国内外食品安全监管体系建设比较研究

本文对国内外食品安全追溯体系、监管队伍和农药残留限量标准建设等方面进行了比较研究。结果表明,发达国家已经建立了较为完善的食品安全追溯体系、有效运转的食品安全监管员制度和严格的食用农产品与食品中农药残留限量标准,我国食品安全监管体系与发达国家还存在一定的差距。针对我国相关方面的工作提出了建议,认为我国应按照《食品安全法》要求,尽快建立食品安全追溯体系,加强食品安全监管员队伍建设,加强农药使用管理,完善食用农产品及食品中农药残留限量标准。     

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.
