Detection method and detection device for food safety by use of supersonic wave

Abstract

The invention relates to a detection method and a detection device for food safety by use of supersonic wave The detection method uses supersonic wave reflection or transmission for detection of food to be detected. The detection method is as follows: 1, detection device probes are immersed in liquid food to be detected or are applied to vessel walls or are placed at positions with a distance away from the two sides of food to be detected; 2 according to a measurement mode, the two probes can receive or transmit the supersonic wave for once or multiple times, and can record the receive-transmit time interval and receiving wave intensity; 3, relevant values of same-kind food with different quality can be collected for establishing the relationship between the quality of the kind of food and directly measured data by use of data fitting or a regression analysis method; and 4, a database of the relationship is established, and the corresponding quality can be picked up from the database according to measurement results. The detection device is characterized by using the supersonic wave detection method of the invention, and the detection device comprises the supersonic wave probes, a processing circuit, memory and corresponding decoding circuits, a communication module, a display unit and an operation panel.

Description

【Technical field】 [0001] The invention relates to a detection technology, in particular to a detection technology using ultrasonic technology to detect the quality of liquid and some solid foods to ensure food safety. 【Background technique】 [0002] With the continuous development and progress of industrial technology, food production is becoming more and more industrialized and streamlined, so more and more harmful chemicals are introduced by industrial methods for reasons such as high yield, pest control, and freshness preservation. In recent years, as people pay more and more attention to health and safety, the issue of food safety has been paid more and more attention. The above problems have caused widespread concern; at the same time, the fake, inferior and poisonous products produced by some illegal manufacturers have made the food safety situation even worse. The situation worsened. Under such circumstances, it has led to widespread distrust of food safety among the...

Problems solved by technology

In recent years, as people pay more and more attention to health and safety, the issue of food safety has been paid more and more attention. The above problems have caused widespread concern; at the same time, the fake, inferior and poisonous products produced by some illegal manufacturers have made the food safety situation even worse. situation worsened

Under such circumstances, it has led to general distrust of food safety among the people, and it is an urgent need for the general public to know the results of universal, accurate and effective food safety testing in a timely and comprehensive manner.

At present, due to the large number of high-end products on the market and the lack of an effective unified testing and management announcement system, a cheap, portable, easy-to-use, fast and accurate testing method and device has been developed to allow the common people to personally monitor food safety on a daily basis. Testing is important and urgently needed
