Embodiment 1

[0045] see figure 1 with image 3 , a database based on near-infrared rapid detection of mutton quality, including a qualitative identification module, a crude protein measurement module, a crude fat measurement module, a fatty acid measurement module, an amino acid measurement module and a grading module, wherein:

[0046] The positioning identification module qualitatively identifies the mutton according to the spectral clustering analysis results.

[0047] The crude protein determination module is used for the rapid determination of the nutritional components of mutton crude protein.

[0048] The crude fat determination module is used for rapid determination of mutton crude fat nutrients.

[0049] The fatty acid determination module is used for rapid determination of mutton fatty acid nutritional components.

[0050] The amino acid determination module is used for rapid determination of mutton amino acid nutrients.

[0051] The grading module is used to comprehensively ...

Embodiment 2

[0056] On the basis of Example 1, please refer to Figure 2-6, a method for establishing a database based on near-infrared rapid detection of mutton quality, including the following methods:

[0057] Step 1. Sample collection: Collect spectral data of different breeds of sheep. Different breeds of sheep include Arbas cashmere goats, Ujimqin sheep, Dorper sheep, Suffolk sheep and Daqingshan goats, covering the front legs , Hind leg, intercostal, tenderloin and gluteus muscle tissue, use the analyzer to collect near-infrared spectral data of fresh meat samples on site, and record the number, age, gender and breed-related information of the sheep where the samples were collected.

[0058] Step 2. Preliminary sample treatment: Divide the samples into fresh meat samples and frozen meat samples, put the samples into liquid nitrogen, and finally put them in the refrigerator for future use. The storage temperature of the refrigerator is -80°C.

[0059] Step 3. Determination of variou...

Abstract

The invention provides a database for rapidly detecting mutton quality based on near infrared and an establishment method thereof, and relates to the technical field of mutton quality detection. The database comprises a qualitative identification module, a crude protein determination module, a crude fat determination module, a fatty acid determination module, an amino acid determination module anda grading module. According to the invention, by establishing a mutton database containing crude protein, crude fat, amino acid, fatty acid and other nutritional indexes, meat color, brightness, PH and other physical indexes, and corresponding spectral information of mutton, the operation is simple, the cost is low, the purposes of quantitative analysis of nutritional ingredients and quality grading can be achieved through simple spectral scanning, and meanwhile, a reliable detection model is also provided, the detection accuracy of crude protein, crude fat, amino acid and fatty acid of nutritional indexes is extremely high, the blank of quantitative indexes of mutton grading is filled, and the grading accuracy is 95% or above.

Description

technical field [0001] The invention relates to the technical field of mutton quality detection, in particular to a near-infrared-based rapid detection mutton quality database and a method for establishing the same. Background technique [0002] Mutton can protect against wind and cold, and can also nourish the body. All deficiencies such as postpartum physical deficiency have therapeutic and tonic effects, and are most suitable for consumption in winter, so they are called winter tonics and are very popular among people. [0003] Using manual methods to detect the quality of mutton will consume manpower, the detection effect is low, and it is difficult to classify the quantitative indicators of mutton. The classification accuracy is not good, and it is difficult to meet the needs of users. Contents of the invention [0004] The purpose of the invention provided by the present invention is to provide a database for rapid detection of mutton quality based on near-infrared ...
