Abstract

The invention relates to the technical field of egg detection, and discloses an egg freshness detection device and method based on synchronous fluorescence. The detection device comprises an underframe, a sample holder and a light shielding cover; the top of the underframe is provided with the sample holder, samples to be detected and covered by the light shielding cover are placed on the sample holder, the inferior of the said samples is a quartz glass window arranged at an opening of the top of the underframe, the lower side of the quartz glass window is vertically provided with a light source emitter and obliquely provided with a light receiving probe; the light source emitter is connected to a light source system by emitting fibers, the light receiving probe is connected to a light sensor by receiving fibers, the light source system and the light sensor are both connected to a controller, and the controller is connected to a computer. The egg freshness detection device and method have the advantages of fast and non-polluted process, nondestructive measurement of the egg freshness, low cost, convenience in operation, high quality and accuracy of detection, and potential for real-time online detection application.

Description

technical field [0001] The invention relates to the technical field of egg detection, in particular to an egg freshness detection device and detection method based on synchronous fluorescence. Background technique [0002] Eggs contain a lot of vitamins, cholesterol, calcium, protein, etc. Eggs contain almost all nutrients for the human body. Eggs are easy to buy in the market and supermarkets, and they are a daily necessity for the public. Fresh eggs are rich in nutrients, and the nutrients in expired eggs are easy to lose and deteriorate. Identifying whether eggs are fresh has become an important part of food safety. Consumers often cite loss of freshness as the main indicator of declining egg quality. The eggs purchased in my country every year account for more than 10% of the total loss due to deterioration. But for a long time, non-destructive testing of egg freshness has been a difficult problem. Most small and medium-sized enterprises in China use physical methods ...
