Abstract

The invention discloses a portable rapid food and drug quality detection device and method. The device comprises a sample pool, a laser radiating unit, an ultrasonic detector, a signal processing unit, a control display unit and the like. By virtue of an opto-acoustic non-destructive testing technology, the detection method, compared with a liquid / gas phase chromatographic method, can be used for directly detecting a tested sample without performing complex preprocessing operation on the sample, and irreversible destructiveness on the nature of the tested sample can be avoided; and compared with non-destructive detection methods such as near infrared spectroscopy, the detection method can relatively well avoid adverse impact of scattered light from components inside the sample on the transmission or reflection spectrum measurement of the tested sample, so that the detection accuracy is greatly improved. As an embedded system and a control display unit touch screen adopted by a large pulsed laser and a data processing unit are replaced by virtue of a laser diode rotating device, the detection device disclosed by the invention is relatively high in integration degree, and is relatively low in cost when multiple excitation wavelengths of a light source is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of food and drug quality safety detection, in particular to a portable food and drug quality rapid detection device and detection method. Background technique

[0002] In recent years, counterfeit, shoddy or even poisonous food and medicines have emerged one after another, such as waste oil, poisoned rice, poisonous capsules and counterfeit medicines. People are increasingly worried that there are serious quality and safety problems in the daily necessities of food and medicines. Although the government and food and drug quality supervision departments have stepped up efforts to crack down on counterfeit and shoddy food and drugs, similar incidents still occur from time to time, causing great psychological panic and integrity crises to the people and society. At present, the places where formal food and drug testing can be carried out in my country are still the quality inspection and quarantine inspection d...
