The invention discloses a fast detection method and detection device for authenticity of edible plant oil based on an optical fiber type fluorescence spectrum technology, and relates to the field of food detection. The device consists of the following components: a light source, a sample pool, a fluorescence detector and a computer. The light source and the sample pool are connected through optical fibers, the sample pool and the fluorescence detector are connected through optical fibers, and the fluorescence detector and the computer are connected through a data cable. The fast detection method for the authenticity of the edible plant oil based on the device is carried out according to the following steps: (1) firstly, collecting fluorescence spectrum data; (2) obtaining a database of chemical indicators related to the authenticity; (3) extracting fluorescence data characteristic information and carrying out data preprocessing; and (4) establishing a mathematical model and carrying out fast detection of unknown samples. The method has the advantages of fast detection speed, simple operation and portable equipment.
Description
technical field [0001] The invention relates to a method and device for quickly detecting the authenticity of edible vegetable oil, in particular to a method and device for detecting the authenticity of edible vegetable oil based on fluorescence spectrum. technical background [0002] Edible vegetable oil is rich in unsaturated fatty acids, vitamin E and other nutrients, and is an essential and important raw material in food processing. At present, China's edible vegetable oil market is in the initial stage of development, especially the high-end edible vegetable oil represented by olive oil and tea seed oil, and the bulk edible vegetable oil represented by soybean oil, palm oil, rapeseed oil and peanut oil, which are popular among food processing enterprises and consumers. widely loved by readers. Due to the large difference in the cost of edible vegetable oil from different sources and different processing methods, this has induced unscrupulous companies in the food indus...
