生物胺是一类具有生物活性的含氮、低分子质量有机化合物的总称,普遍存在于水产品等蛋白质和氨基酸含量较高的食品中,与腐败微生物密切相关,水产品在长时间的贮存和售卖过程中容易受到微生物的作用而腐败变质,产生超标的、对人体有害的组胺等生物胺,因此,生物胺的检测技术十分必要。本文详细综述国内外测定水产品中生物胺的前处理方法、检测方法及其优缺点,并展望了生物胺检测技术的发展前景,为水产品中生物胺的检测提供技术基础和方法学依据。  相似文献

食品中的生物胺及其检测方法   总被引:5,自引:0,他引:5  
生物胺普遍存在于生物体中,有重要的生理功能.许多天然食品中都含有生物胺.摄入大量生物胺会引起身体不适,严重的还可能危及生命.引起食物中毒的生物胺主要包括组胺和酪胺.此外,存在大量微生物的食品中,生物胺的含量较高,同类食品中生物胺的种类和含量又有很大的变化,这一现象受许多因素影响,如微生物的种类和数量、温度、pH值等.生物胺含量还与食品的腐败变质有关,是食品品质的指示器,因此对于生物胺的检测受到重视.目前检测食品中生物胺含量的方法主要有薄层色谱、气相色谱、毛细管电泳和高效液相色谱.  相似文献

生物胺是一类低分子量的、广泛地存在于食品中的、具有生物活性的有机化合物,含量在一定范围内时是对人体有益的生物活性物质,若超过其限值将会给人体带来严重的影响,因此,有效地检测食品中的生物胺对保护人们的健康尤为重要。饮料酒中生物胺主要来自于发酵过程,因此国内外生物胺的检测多集中于啤酒、葡萄酒、黄酒等发酵酒。随着现代检测分析技术的发展,低检出限、高灵敏度、高准确度的检测方法不断涌现,实现了从过去常量组分检测到现在的痕量乃至超痕量组分检测的跨越。本文综述了啤酒、葡萄酒、黄酒中生物胺的检测方法 ,以期为今后生物胺的检测提供便利。  相似文献

生物胺(biogenic amine,BA)作为一种具有生物活性、含氨基的低分子量化合物,主要由氨基酸进行脱氨基作用而产生。该类物质广泛存在于天然及加工后的食品中,适量摄入生物胺能够对机体的生理功能产生积极作用,但一旦摄入过量会导致不适,严重时甚至会危及生命。因此,建立灵敏、快速、高通量的生物胺前处理和检测方法与人体健康息息相关。目前,常用于样品中生物胺检测的前处理技术包括液液萃取、固相萃取和基质辅助固相分散萃取等,常用的检测方法有液相色谱-质谱法、液相色谱法、气相色谱法、薄层色谱法、毛细管电泳法和生物传感器法等。本文对生物胺的种类与生理作用、前处理方法与检测方法的最新进展进行了综述,以期能够为食品及生物制品中生物胺含量的检测提供参考。  相似文献

Biogenic amines (BAs) represent a considerable toxicological risk in some food products. Putrescine is one of the most common BAs in food. Its increased occurrence in food may lead to alimentary poisoning, due to enhancement of the toxic effects of other BAs, and also to lower quality of food, this amine is potentially carcinogenic. Increased occurrence of putrescine in food is mainly due to the bacterial metabolism of the Gram‐negative as well as Gram‐positive bacteria present. The bacterial metabolism of putrescine is very specific due to its complexity (in comparison with the metabolism of other BAs). There are 3 distinct known pathways leading toward the formation of putrescine, in some splices involving up to 6 different enzymes. The existence of more metabolic pathways and the possibility of their simultaneous use by different bacteria complicate the specification of the best conditions for food production and storage, which could lead to a lower content of putrescine. This review provides a summary of the existing knowledge about putrescine production and detection (mainly detection of specific genes for different enzymes using polymerase chain reaction) in both starter and contaminating microorganisms. Thus, this comprehensive review gives a useful overview for further research.  相似文献

ABSTRACT

This study aimed to investigate the presence of eight biogenic amines (BAs): tryptamine (TRP), phenylethylamine (PHE), putrescine (PUT), cadaverine (CAD), histamine (HIS), tyramine (TYR), spermidine (SPD) and spermine (SPM) in cheese, fish & fishery products and meat & meat products obtained from the Croatian retail market. A selective and robust method of high-performance liquid chromatography (HPLC) with diode array detection (DAD) was applied for the determination of BAs in a total of 91 samples in accordance with the performance criteria outlined in the European legislation. A high inter- and intra-food group variability of the amounts of BAs was observed. In the analysed samples, the most represented amines were TYR, HIS, CAD and PUT. Based on the highest content of the most toxic BAs (HIS and TYR) and consequential food safety concerns, the studied food groups can be ranked in the following order: cheese (HIS up to 106.4 mg/kg; TYR up to 206.6 mg/kg), fish &fishery products (HIS up to 98.8 mg/kg; TYR up to 47.9 mg/kg), and meat & meat products (HIS up to 20.0 mg/kg; TYR up to 117.5 mg/kg). The total BA content was significantly higher (p < .05) in fermented in comparison with other food. The study aimed to contribute to the knowledge on BA toxicity and food quality, as well as to support the indispensable future studies of consumption data and exposure assessment, to the end of defining allowable BA concentrations in food.  相似文献

Biogenic amines are produced by bacterial decarboxylation of corresponding amino acids in foods. Concentration of biogenic amines in fermented food products is affected by several factors in the manufacturing process, including hygienic of raw materials, microbial composition, fermentation condition, and the duration of fermentation. Intake of low amount of biogenic amines normally does not have harmful effect on human health. However, when their amount in food is too high and detoxification ability is inhibited or disturbed, biogenic amines could cause problem. To control concentration of BAs in food, decarboxylase activity for amino acids can be regulated. Levels of BAs can be reduced by several methods such as packaging, additives, hydrostatic pressure, irradiation, pasteurization, smoking, starter culture, oxidizing formed biogenic amine, and temperature. The objective of this review paper was to collect, summarize, and discuss necessary information or useful data based on previous studies in terms of BAs in various foods.  相似文献

Biogenic amines (BAs) are biologically active molecules which have aliphatic (putrescine, cadaverine, spermine, spermidine), aromatic (tyramine, phenylethylamine) or heterocyclic (histamine, tryptamine) structures. They can be detected in raw and processed foods which are formed and degraded through several pathways during the metabolic processes of animals, plants and microorganisms. The identification and quantitation procedures of BAs in food samples are very important, because BAs are considered as the indicators of food quality and freshness. The determination of BAs are commonly achieved by separation techniques such as high-performance liquid chromatography (HPLC), gas chromatography (GC) and capillary electrophoresis (CE). In this article, analysis of BAs in foods were reviewed from 2007 to present.  相似文献
