Abstract

The invention discloses a device and a method applicable to rapid olive oil detection. The device is structurally based on laser of a semiconductor laser emitter. An included angle of 45 degrees is formed between a first beam splitter and an optical axis; a first power meter is adopted to record light reflection power of the first beam splitter in a direction of 90 degrees of the laser; a first cuvette is positioned in the center of a first integrating sphere and is coaxial with the laser; a first optical fiber probe is connected with a first spectrograph through a first optical fiber and is used for recording a fluorescence spectrum inside the first integrating sphere; an included angle of 45 degrees is formed between a second beam splitter and the optical axis; a second power meter is adopted to record light reflection power of the second beam splitter in the direction of 90 degrees of the laser; a second cuvette is positioned in the center of a second integrating sphere and is coaxial with the laser; a second optical fiber probe is connected with a second spectrograph through a second optical fiber and is used for recording a fluorescence spectrum inside the second integrating sphere; a third power meter is adopted to record power of the laser penetrating through the second integrating sphere. By adopting the device and the method, the purpose of rapidly detecting olive oil can be achieved through a fluorescence emission spectrum and transmissivity at 450nm.

Description

technical field [0001] The invention relates to an olive oil detection technology, in particular to a device and method suitable for rapid detection of olive oil. Background technique [0002] Since 2000, domestic olive oil imports have been increasing day by day, from the original annual imports of several hundred tons to the current annual imports of 38,600 tons (2015). The main reason is that China's geographical environment is not suitable for mass production of olive oil. Taking 2014 as an example, the total output of olive oil in China was only 1,732 tons, which cannot meet the demand of the domestic olive oil market at all (statistics are provided by the National Bureau of Statistics, the General Administration of Customs and the Ministry of Commerce). Therefore, foreign olive oil producing countries are vying for the Chinese market, and are increasing their efforts to develop the Chinese market. However, the total annual output of high-quality olive oil in the world...
