地理原产地

由于食品造假问题日益?#29616;兀?#39135;品和饮?#29616;?#36896;?#38518;?#23547;求核实原材料和成品地理原产地的方法。

例如:红酒的质量和价格部分取决于生产该红酒的葡萄的原产地,因此,葡萄酒产地溯源对品牌保护具有重要意义。借助我们的电感耦?#31995;?#31163;子体质谱系统和相关统计软件进行元素分析,可将葡萄酒中的微量金属含量与土壤相关联,从而区分其地理原产地。

对其他高级食品(如:橄榄油)进行类似分析,也能够确定其地理原产地。

掺假

掺假现象已经存在了数千年,2007年中国的三聚氰胺?#24405;?#26159;首个被报道的使大量动物和婴儿致病的事故。为了保护全球消费者,我们可为食品公司和食品加工商提供掺假鉴别的工具。

例如:

  • 我们的FT-IR和FT-NIR系?#25104;?#30340;掺杂筛查软件能够在一分钟内对掺杂物进行?#32454;?不?#32454;?#31579;查,而无需进行样?#20998;?#22791;,且具有最小的科学?#23576;啊?/li>
  • 我们的奶粉分析仪采用先进的算法筛选已知和未知的掺杂物。此外,该仪器还能对蛋白质、水分和脂肪营养参数进行快速常规测量。
  • 我们的GC/MS解决方案可按多个国际监管机构规定的监管限?#21040;胁?#37327;。

以上仅为珀金埃尔默公司根据创新技术帮助?#33455;?#20154;员鉴别食?#20998;?#25104;分替代品、保护世界供应链的几个示例。

    Guide to Herb & Spice Adulteration Screening Using NIR

    Food fraud and adulteration has become of particular concern to the industry over the past few years following reports of incidents in the media, with herbs and spices identified as one of the key problem areas. NIR spectroscopy used with the method outlined here can provide a rapid screening technique for detecting adulteration in herbs and spices.

    A novel method (TG-IR) for the rapid determination of Total Petroleum Hydrocarbons (TPH) in soil

    A gas chromatographic analysis of the extract can provide even greater sensitivity and more detailed compositional information, but further increases the time required for the analysis. Thermogravimetric analysis coupled to infrared spectroscopy (TG-IR) can provide detailed information about the amount and nature of the pollution, while requiring no sample preparation at all. This application note illustrates the kind of data that can be obtained with a modern TG-IR system.

    Augmenting Standard Methods of Measuring Airborne PM2.5 Using IR Imaging

    The use of IR imaging expands the measurement possibilities by giving information about the individual types of materials present in the collected particles. The information from the IR imaging experiment is not only qualitative (i.e. identification of the particulates), but can also be calibrated to give quantitative information on the components present. The IR imaging measurement will take only five minutes, whereas Ion Chromatography requires solvent extraction of the particulates and would take around 20-25 minutes per sample

    Determining the Source Oil of Biodiesel with Infrared Spectroscopy

    Infrared spectroscopy is particularly suitable for the identification of materials, even when the differences between the materials are subtle variations in complex mixtures. In this note we demonstrate that biodiesel from several common feedstocks can be distinguished on the basis of absorption bands arising from double bonds in the fatty acid chains.

    Diamond ATR and Calibration Transfer for Biodiesel-Blend Analysis by ASTM D7371

    Biodiesel is seldom used neat (B100), typically being blended with fossil diesel at ratios from 5% v/v (B5) to 30% v/v (B30). Verifying the FAME content of diesel-fuel blends is an important aspect of quality control and auditing of blending and distribution operations. Because FAME has a strong infrared absorption at 1745 cm-1 due to the ester carbonyl group, infrared spectroscopy is an excellent technique for this analysis, and there are EN and ASTM? standard test methods describing the procedure

    Cavity-enhanced Absorption Spectroscopy for Trace Gas Detection with Frontier

    Cavity-enhanced absorption spectroscopy (CEAS) has similarities with the better known cavity ringdown technique (CRDS) which measures the signal decay as a laser pulse emerges through one of the mirrors after successive reflections. By measuring the increase in the rate of decay caused by an absorbing species, CRDS can measure ppb concentrations of small molecules. The ringdown technique has typically been applied to small molecules where the wavelength of a NIR laser source can be tuned across very narrow individual lines of the spectra. In contrast this report describes CEAS using a broadband source applied to larger molecules where the spectra are broader.

    Analysis of Bioethanol Impurities with the Spectrum Two FT-IR Spectrometer

    The intensifying global emphasis on developing sustainable fuel supplies has led to increasing use of fuels derived from biological sources. In this note we show that the Spectrum Two? FT-IR spectrometer (Figure 1) can be used to develop a quantitative method with sufficient sensitivity to meet the required detection limits for methanol, water, C3–C5 alcohols and gasoline denaturant, while requiring less than two minutes of analysis time per sample.

    Discrimination of Herbal Lifestyle Products Using AssureID SIMCA and COMPARE Algorithms

    Herbal lifestyle products are widely used as alternatives to medicines around the world, with as many as 80% of people using them as a primary source of healthcare in developing countries. These treatments are commonly regarded by scientific papers, and on some occasions the media, as being inferior to orthodox treatment. This is due to the variation between herbal formulations which will not be present in so called ‘single-chemical’ drugs. The reasons for the aforementioned variation involve several factors including storage, environmental conditions, handling and unintentional or intentional contamination (adulteration).

    Determination of Benzene in Gasoline by ASTM D6277 with Spectrum Two

    IR spectroscopy is an ideal method for quantifying benzene at the concentration levels required, and there are several standard methods for this measurement, all of which utilize the distinctive C–H out-of-plane deformation band at around 673 cm-1. While this band is characteristic of benzene, toluene and xylenes have some weak absorption at this frequency that can interfere with the results if high concentrations are present.

    Determination of Oil Content in Membranes Used in Compressed Air Sampling by Infrared Spectroscopy

    This note describes the test method for the quantitative analysis of aerosol oil and liquid oil typically present in the air discharged from compressors and compressed air systems. The method is rapid, sensitive and cost effective and shows the FT-IR can be an effective tool for the monitoring of oil content. The methodology followed for the analysis by FT-IR is reported in Bureau of Indian Standard and we have also tested for its ruggedness, spike recovery, linearity and detection limits.

    Biodiesel Concentration Measurements Using Attenuated Total Reflectance (ATR)

    Biodiesel fuels are often blended compositions of diesel fuel and esterified soybean oils, rapeseed oils, or other potential vegetable oils as well as fats. The physical and combustion properties of these biofuels have allowed them to achieve similar performance to diesel fuel. However, there are several characteristics that are of concern. These differences, especially the cetane reduction, require that adequate control of the biofuel concentration be implemented.
