Embodiment Construction

[0032] The specific implementation of the present invention will be further described in detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0033] Hyperspectral imaging technology combines traditional image and spectroscopy technology, and can obtain the spatial position information and spectral information of the object to be measured at the same time, so it can better reflect the comprehensive properties of the sample. Bosoon Park and others successfully detected the contamination of poultry meat surface excrement by using hyperspectral technology, with an accuracy rate of 96.4%. Yankun Peng et al. used hyperspectral imaging technology to study the optical diffusion characteristics of fruits and proved that this method is an effective way to detect the intrinsic quality (hardness, sugar content) of fruits. The present invention is completed ba...

Abstract

The invention discloses a method for rapidly and nondestructively detecting the colony count of chilled meat, which comprises the following steps of: S1. obtaining a chilled meat sample; S2. collecting a high-spectrum image of the sample; S3. calculating the reference value of the colony count per unit area of the sample; S4. subjecting the high-spectrum image to space decomposition so as to obtain spatial diffusion information of the sample at different wavelengths, wherein the Lorentz parameters of the component information of the representative sample is extracted by utilizing the spatial diffusion information according to a nonlinear regression method; and S5. obtaining the relationship between the Lorentz parameters and the reference value in a certain wavelength range so as to establish a mathematical model of the Lorentz parameters and the colony count of the sample according to a multivariate linear regression method, and predicting the colony count of the chilled meat sample by utilizing the model. By means of the method disclosed by the invention, rapid and nondestructive detection of the colony count of a meat product can be realized.

Description

Technical field [0001] The invention relates to the field of meat quality safety detection, in particular to a method for quickly and non-damagingly detecting the total number of colonies of chilled meat. Background technique [0002] my country is a major pork producer and consumer. According to the 2008 statistics report on livestock production, my country’s total annual meat output is 72.69 million tons, of which 46.15 million tons of pork, accounting for approximately 63.5%, and 46% of the world’s total pork output. First in the world. Currently, pork supply mainly comes in three forms: hot fresh meat, frozen meat, and chilled meat. Chilled pork is a new type of consumption that has emerged in my country in recent years. Due to its good nutrition and good flavor, there has been a consumption boom of "Chilled Meat World" in large and medium-sized cities, and its market share has been expanding year by year. Abroad, developed countries such as Europe and the United States almo...
