Meat product adulteration detecting platform based on Raman spectrum

Abstract

The invention relates to meat product adulteration detecting platform based on Raman spectrum. The meat product adulteration detecting platform comprises a sample pool (16), a light sensor (14), a controlled motor (15), a control module (13), a laser (1), a first focusing lens (2), a first light filter (3), a first one-way reflector (6), a second one-way reflector (4), a second focusing lens (5), a second light filter (7), a third focusing lens (8), a diffraction grating imaging system (9) and a computer, wherein the sample pool (16) comprises a sample pool body (16-4) and a transparent support plate (16-5) located in the sample pool body (16-4), a top cover (16-6) is disposed on the sample pool body (16-4), the sample pool (16) is provided with a sensor hole (16-3), the bottom of the sample pool (16) is provided with a measuring hole (16-2), and a focusing sleeve (16-1) is fixed at the measuring hole (16-2). By the meat product adulteration detecting platform, meat product adulteration detecting can be achieved fast.

Description

Technical field [0001] The invention belongs to the field of food safety detection and relates to a rapid detection platform for meat product doping based on portable Raman spectroscopy. Background technique [0002] As a food with complete nutrients, good taste and easy absorption by human body, meat has won the favor of consumers. With the development of the national economy and the improvement of people's living standards, the consumption of meat products in our country continues to increase, and the quality problems of meat products are also emerging in endlessly. Especially with the frequent occurrence of meat safety incidents such as "falsified beef and mutton", "water-injected meat", "disease pork" and other meat safety incidents in recent years, the adulteration of meat products has become one of the outstanding contradictions affecting my country's food safety at present. It endangers the life and health of the people and arouses great concern from the whole society...

AI Technical Summary

Problems solved by technology

[0003] In practical applications, there are few reports on the application of Raman spectroscopy in the diagnosis of adulteration in meat products. The main reason is that there are three defects in conventional Raman spectroscopy detection: (1) The laser focus position affects its measurement results Larger, resulting in unstable detection results; (2) Raman spot is small, for uneven samples such as meat products, a single detection is not representative; (3) The detection lens is easily contaminated, resulting in poor detection stability
