Abstract

The present invention relates to the technical field of food detection, in particular to a method for viscoelasticity non-destructive detection of livestock and poultry meat, the method comprising: S1, placing the sample to be tested on a lifting platform and below the sensor head of a laser positioner; S2, The sample to be tested is driven by the lifting platform to perform a lifting movement, so that the distance between the surface of the sample to be tested and the sensor head is a preset value; S3, the air source device is used to generate airflow, and the airflow is input to the sample to be tested through the gas pipeline surface to form a non-contact force; S4, collect the displacement information of the surface of the sample to be tested during the stress process through the sensor head, and feed back the collected displacement information to the lower computer; S5, the lower computer will feedback the displacement information Send it to the host computer for viscoelastic analysis. The method effectively combines airflow pulse and laser ranging technology, so as to realize the non-contact and non-destructive detection of the viscoelasticity of livestock and poultry meat.

Description

technical field [0001] The invention relates to the technical field of food detection, in particular to a viscoelastic nondestructive detection method of livestock and poultry meat, in particular to a viscoelastic nondestructive detection method of livestock and poultry meat based on airflow pulse and laser ranging technology. Background technique [0002] At present, the consumption of livestock and poultry meat in my country is increasing year by year. Improving the quality and processing of livestock and poultry meat products to ensure their safety and nutritional value is a major issue related to people's livelihood. Livestock and poultry meat is rich in protein, and the protein and its hydration layer form a network structure, which has a certain ability to resist external forces. This resistance is manifested as the viscoelasticity of meat. [0003] When testing the viscoelasticity of livestock and poultry meat, it is necessary to ensure that the sample is non-contact ...
