Food Authenticity
Especially within the EU there are many examples of protected products of designated origin (PDO-Product of Designated Origin), to name a few, specific brands of cheese e.g. mozzarella, marzipan, wine, beer, sausage, fish and more. These brands are looking for ways to protect their unique PDO If the products of different regions are well known, defined and have specific markers, it is possible to use a targeted MS approach for this analysis. For new products or regions gaining PDO certification, a different approach is required called ‘unknown and untargeted screening’; both workflows can be solved by BrukerMass Spectrometryproducts.
Automated high-resolution1H-NMR spectroscopy, combined with multivariate statistical chemometrics, provides unique "all-in-one" capabilities for food authenticity control and brand protection.
NMRis targeted and non-targeted likewise. The technique is able to simultaneously observe hundreds of components in the food and due to its high reproducibility acquire a so-called fingerprint of the samples,允许针对特定标记成分的有针对性量化，以及基于统计的指纹识别，用于非目标检测和确定原点- all within the same experimental run.
Adulteration Screening
Maintaining brand reputation and product quality has led to increased focus on qualifying raw materials and ingredients used in food production. In addition to traditional quality parameters, detection of adulterants plays a critical role in ensuring food safety and quality. The USP (US Pharmacopeial Convention) Food Fraud Database currently lists hundreds of incidents of economically motivated adulteration (EMA), substitution, counterfeiting or mislabeling of food products, such as wine, cheese, olive oil and milk powder and some prominent adulterants e.g. melamine.
FT-NIR spectroscopy提供了一种有价值的工具，用于筛选几乎所有具有优异成本效益比和无与伦比的原材料的原材料。NIR光谱的高信息含量提供了完整样品的指纹。将传入的原材料与使用已知质量样品测量的原材料进行比较，可以在检测极限内对掺杂剂或污染bob综合游戏物进行非目标筛选。如果通过FT-NIR对掺假呈阳性测试，则采用互补分析方法进行进一步研究NMR或者MScan be carried out to determine the exact identity of the adulterant.
TheNMRmeasures the spectra which contains hundreds of signals and reflects the fingerprinting of the tested food product. It allows targeted quantification of specific marker components, as well as statistics-based fingerprinting for nontargeted detection of adulterants - all within the same experimental run. In case of honey, as an example, a targeted analysis of up to 60 markers is applied to verify for the presence of sugar syrup, which is considered an adulteration.
食物的掺假已经存在了很多年。在大多数情况下，目的是降低原材料成本并增加利润。bob综合游戏如果没有适当的筛查，就很难确定这一点，并且不可能将欺诈者提出法庭。新开发的技术使检测掺假变得更加容易。High Resolution QTOF systemsare pushing the detection limits down and newIon Mobility MS systems能够增加分离，两种技术都将提供更多的可能性，以区分不同的食物添加和较低的添加水平。
