Detection data acquisition method for viscoelasticity of livestock and poultry meat based on airflow and laser

Abstract

The invention belongs to the technical field of food detection, in particular, relates to a detection data acquisition method for viscoelasticity of livestock and poultry meat, and specifically, relates to the detection data acquisition method for the viscoelasticity of the livestock and poultry meat based on airflow and laser ranging technologies, wherein the method includes the following steps:S1, preparing livestock and poultry meat samples; S2, acquiring strain data; S3, determining the stress value; and S4, obtaining a strain-time curve and a stress-strain curve, and analyzing the viscoelasticity of the livestock and poultry meat. The adopted airflow and laser technologies have non-contact and non-destructive advantages, can obtain the corresponding strain and stress data for different livestock and poultry meat samples, thereby obtaining important data for the viscoelasticity study of the livestock and poultry meat.

Description

technical field [0001] The invention belongs to the technical field of food detection, and in particular relates to a data collection method for viscoelasticity detection of livestock and poultry meat, in particular to a data collection method for detection of viscoelasticity of livestock and poultry meat based on airflow and laser. Background technique [0002] Livestock and poultry meat is a typical viscoelastic body, which has both the elastic properties of solid and the viscous properties of liquid. 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] At present, the domestic research work is mainly focused on the pure elasticity of meat, which cannot fully reflect the viscoelastic characteristics of meat products; the detection of meat viscoelasticity at home and abroad usually uses univ...

AI Technical Summary

Problems solved by technology

[0003] At present, the domestic research work is mainly focused on the pure elasticity of meat, which cannot fully reflect the viscoelastic characteristics of meat products; the detection of meat viscoelasticity at home and abroad usually uses universal testing machines, texture analyzers, etc. Perform compression destructive experiments on samples

This detection method produces contact and irreversible damage and pollution to the sample, and the sample after the test loses its subsequent use value, and this type of instrument is expensive and not easy to popularize
