Olive Oil Analysis Using FT-NIR Spectroscopy

橄榄油消费量正在继续在全球范围内增长，使其成为高价值的食品。无论企业在橄榄油行业中的哪个地位对于企业的声誉都重要，即保证其石油的质量和真实性。此外，还必须有效地进行石油加工以提高盈利能力。

近红外光谱原理

NIR（近红外光谱法）正在成为食品行业的宝贵工具，使企业能够迅速进行流程监测，质量控制并提高效率。高级Fourier Transform Near-Infrared (FT-NIR) Spectrometers由Galaxy Scientific提供的坚固耐用，紧凑和低维护性，同时提供出色的性能。

NIR光谱仪通过将样品暴露于NIR激光器（通过样品通过样品或反射）来工作，然后测量其余的NIR激光信号。NIR激光器与样品的相互作用更改了波长，这种变化取决于样品的化学成分。NIR光谱允许仅在一分钟内只能在一分钟内进行一次测量，可以鉴定出样品的所有不同化学成分。

这technique is highly useful because samples do not need to prepared for measurement, they must simply be placed in a cup or vial before introduction to the spectrometer. In addition, the spectrometers are straightforward to use and can be operated with just a touch of the button, meaning non-experts can carry out the analysis.

采用FT-NIR的企业不再需要使用昂贵的实验室或第三方对其橄榄糊，Pomace或Oils进行分析，而可以在内部进行快速，经济和精确的分析。

FT-NIR光谱仪

Galaxy Scientific提供的FT-NIR光谱仪使生产商能够立即化学分析其输入产品，例如橄榄糊和输出产品，例如Pomace和Olive Oil。这种直接的反馈意味着生产者可以调整其提取过程以提高产品质量。

FT-NIR can be used to determine the concentration of oil and moisture in olive pastes, allowing harvests to be optimized to reduce product loss and increase profitability.

FT-NIR can also be used to assess the quality of olive oil being produced. Important quality parameters, such as the oil’s -values (K232, K270, delta K, which are important for extra virgin classification), the oxidation state, FFA (free fatty acids) content and acidity, can be measured. In addition, nutritional content and other important parameters can also be determined to help increase profitability when selling to other manufacturers.

还可以评估废物质量的残余油含量，使制造商能够发现未能成功提取多少石油。

QuasIR™ Series—A New Generaion of FT-NIR Systems from Galaxy Scientific

这FT-NIR systemsfrom Galaxy Scientific have been designed by expert scientists with the requirements of the olive oil industry in mind. The instrument is easily operated via a simple point-and-click interface. Single measurements can be carried out at the touch of a button using the system’s Spectral Sage EZ software. Custom reports can be produced with batch and lot IDs included for later reference.

这QuasIR™ 4000 is can be used for both at-line and on-line measurements, being able to analyze paste and pomaces in reflection mode, and oils in transmission mode.

这QuasIR™ 2000can be used to automate measurements, providing continuous, dynamic data, making it perfect for use in high-volume production environments. Sample probes can be inserted directly into the production pipeline, with the IR data sent to the instrument via fiber optic cables. Reflection probes can be used to analyze solid process materials, such as pomace and pastes, whereas a transmission probe can be used to analyze olive oil.

Galaxy Scientific的新多路复用器意味着可以使用单个仪器来测量多达十个采样点。这降低了运行光谱分析的成本，并改善了制造商在仪器上的投资回报率。
