摘要

利用基于光纤探针的近红外光谱技术研究了橄榄油与棕榈油的掺假,并从四个峰中进行了鉴定和解释。然后,选择1550 nm左右的峰值,设计了一种低成本的检测掺假的光纤器件。所演示的装置显示,橄榄油中棕榈油体积每变化1%,功率变化0.09 dBm。在研究中观察到掺假的总平均功率变化为9 dBm。在每个体积样品中重复实验100次以上来估计测量误差,功率测量中观察到的平均误差为1.7±0.7 dBm。该设备的测量范围为掺假率为0%-100%,测量精度至少为掺假率为20%,无需任何数据平均;后者可以通过对传感器采集的数据进行信号处理来改善。所展示的低成本光学装置可以无损地、远程和即时地检测橄榄油与棕榈油的掺假,显示出很高的商业化潜力。

Fiber Optic Device for the Detection of Adulteration of Olive Oil With Palm Oil

Fiber Optic Device for the Detection of Adulteration of Olive Oil With Palm Oil

Adulteration of olive oil with palm oil is studied using an optical fiber probe-based near-infrared spectroscopy technique, from which four peaks were identified and explained. Then, the peak at around 1550 nm was selected to design a low-cost fiber optic device to detect adulteration. The demonstrated device shows a power change of 0.09 dBm per 1% volume change of palm oil in olive oil. The total average power change observed in the study was 9 dBm for the adulteration. The experiment was repeated more than 100 times in each volumetric sample to estimate the measurement error, and the average error observed in power measurement was 1.7 ± 0.7 dBm. The device's measurement range was 0%–100% adulteration, and measurement accuracy was at least 20% adulteration without any data averaging; the latter can be improved by signal processing the data acquired by the sensor. The demonstrated low-cost optical device can detect olive oil adulteration with palm oil non-destructively, remotely, and instantaneously, showing high potential for commercialization.
