乙烯利是一种常见的含有磷酸基团的植物生长调节剂,主要作用为释放乙烯与促进植物体释放乙烯,起到使农作物催熟、增产的效果,由于其经济易得,在农业生产中被广泛使用。然而生产实践中缺乏科学有效的指导,存在不合理或过量使用乙烯利的现象,影响人民群众健康的同时导致环境的污染。乙烯利在植物源性食品上的残留量低,常需要进行痕量分析。但由于乙烯利物理性质特殊,极性大、难挥发、无生色基团,且植物源性食品的种类繁多、基质复杂,无法并入现有常用农药多残留分析方法,而目前主流的检测方法步骤烦琐、危险性大,给分析检测造成了一定的困难。因此,本文从国内外研究乙烯利残留分析方法入手,围绕前处理方法及检测方法进行综述,总结现有分析方法的优缺点,并阐述其发展趋势,为研究人员开发简便、经济、可靠的新方法提供参考,为保障食品质量安全研究提供依据。 相似文献

Traditional fermented foods and beverages (TFFB) are important dietary components. Multi‐omics techniques have been applied to all aspects of TFFB research to clarify the composition and nutritional value of TFFB, and to reveal the microbial community, microbial interactions, fermentative kinetics, and metabolic profiles during the fermentation process of TFFB. Because of the advantages of metaproteomics in providing functional information, this technology has increasingly been used in research to assess the functional diversity of microbial communities. Metaproteomics is gradually gaining attention in the field of TFFB research because it can reveal the nature of microorganism function at the protein level. This paper reviews the common methods of metaproteomics applied in TFFB research; systematically summarizes the results of metaproteomics research on TFFB, such as sauces, wines, fermented tea, cheese, and fermented fish; and compares the differences in conclusions reached through metaproteomics versus other omics methods. Metaproteomics has great advantages in revealing the microbial functions in TFFB and the interaction between the materials and microbial community. In the future, metaproteomics should be further applied to the study of functional protein markers and protein interaction in TFFB; multi‐omics technology requires further integration to reveal the molecular nature of TFFB fermentation. 相似文献

A survey of levels of acrylamide (AA) in 349 food products obtained from the Chinese market was conducted. AA was determined by an liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. The limit of detection (LOD) and the limit of quantification (LOQ) of the method in four different matrices ranged from 0.8 to 10 µg kg?1 and from 4.0 to 25 µg kg?1, respectively. The results from this survey indicated that AA was present in all samples except drinking water and tea. AA contents in different samples varied greatly according to the raw materials and processing conditions. The highest level of AA was found in potato products, with an average level of 1467 µg kg?1. Preliminary estimates of AA exposure and risk assessment of AA from foods in the Chinese population were performed using a combination of data obtained in the present survey and 2002 dietary consumption survey carried out in 2002 for the Chinese population. The average dietary exposure of AA was estimated to be 0.38 µg kg?1 body weight day?1, which is relatively low compared with the result reported by the Food and Agricultural Organization/World Health Organization (FAO/WHO). Furthermore, the margin of exposure for neurotoxicity, reproductive toxicity, and carcinogenicity of AA was calculated to be 1318, 5250, and 787, respectively. 相似文献

硝基呋喃类药物一直是国内外普遍关注的常见兽药之一,主要包括呋喃唑酮、呋喃西林、呋喃它酮、呋喃妥因,具有抗菌消炎作用,曾被广泛应用于畜禽水产品的生产过程中。但后来发现,硝基呋喃类药物残留在动物体内被人食用以后,容易导致过敏、头痛、腹泻等症状,严重的还可引发"三致"危害。因此,中国、美国、日本、韩国、加拿大、欧盟等国家禁止该类药物在动物源性食品中检出,并陆续制定相关限量标准,不断投入研究以期建立更好的检测方法并用于监控动物源性食品中硝基呋喃类药物的残留量,以保护消费者和生产者生命安全。建立快速、灵敏、准确的检测方法迫在眉睫。基于此,本研究对硝基呋喃类药物的分类、国内外现行检测标准及方法进行总结和分析。 相似文献
