Abstract

The invention discloses a method for quickly detecting the freshness of pork based on a laser imaging technology. Three pork texture images different in freshness level are collected by utilizing a laser imaging system, can reflect the appearance quality information of the pork and can also reflect the internal structure information of the pork. Firstly, the areas of interest (ROI) of the scattering images are extracted, then the average grey value and variance characteristics of concentric circles and the scattering texture characteristics of the ROI are extracted, a pork freshness classification model is established on the basis, and identification of like pork samples with unknown freshness levels is achieved by applying the model.

Description

technical field [0001] The invention relates to a new method for rapid detection of pork freshness, in particular to a new method for rapid detection of pork freshness based on laser imaging technology. Background technique [0002] Meat is rich in protein, fat, minerals, etc., which can provide rich nutrients to the human body and is an important part of human dietary structure. With the improvement of people's living standards, pork consumption is gradually increasing, accounting for 65% to 70% of the total consumption, and it is the main body of meat production and consumption. Pork is vulnerable to enzymes, microorganisms, etc. during storage, transportation, and processing, resulting in spoilage and deterioration, resulting in a decline in quality. Eating stale or rotten meat not only cannot satisfy people's demand for taste and nutrition, but also endangers people's health and causes diseases. Therefore, detecting the freshness of pork has important public health sig...
