Abstract

The invention relates to the technical field of food detection, and particularly relates to a nondestructive testing method for the visco-elasticity of livestock and poultry meat. The method comprises the following steps: S1. placing a to-be-tested sample on a lifting platform and positioning below a sensing head of a laser position finder; S2. driving the to-be-tested sample to do lifting motion through the lifting platform, so as to enable the distance between the to-be-tested sample and the sensing head to be a preset value; S3. generating an air flow by utilizing an air source device, and inputting the airflow into the surface of the to-be-tested sample through an air delivery pipeline so as to form non-contact acting force; S4. acquiring the displacement information on the surface of the to-be-tested sample during a stressed process through the sensing head, and feeding the acquired displacement information back to a lower computer; and S5. sending the displacement information, fed back by the lower computer, into an upper computer for performing the visco-elasticity analysis. According to the method, the airflow pulse and laser range finding technology are effectively combined, so that the non-contact non-destructive testing on the visco-elasticity of livestock and poultry meat can be realized.

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 ...
