Problems solved by technology

However, because colostrum protein, fat and other indicators are different from normal milk, its value is not within the linear range of the analysis curve of the dairy component analyzer, and its viscosity is high, so it cannot be directly measured

Embodiment 1

[0023] Embodiment 1, rapid detection physical and chemical index of bovine colostrum

[0024] The bovine colostrum sample is diluted with distilled water, and the fat content dilution ratio is bovine colostrum: water=3:5, and the detection protein content dilution ratio is bovine colostrum: water=3:10, and the detection dry matter content dilution ratio is bovine colostrum Milk: water = 3:5. Heat the water bath to 40°C and mix with a vortex shaker. Fourier transform infrared full-spectrum scanning dairy component analyzer parameter selection "milk" test module and the indicators to be detected. Three parallel detections were carried out on the samples by a Fourier infrared full-spectrum scanning dairy component analyzer, and the actual content of the substance was obtained by multiplying the measured results by the corresponding dilution factor. The test results of the analyzer are compared with the national standard test method, and the results are shown in Table 2 below. ...

Embodiment 2

[0034] Embodiment 2, rapid detection of physical and chemical indicators of bovine colostrum

[0035] Use the method of the present invention and the national standard method to detect the physical and chemical indicators of the samples (1-3 days) from the same pasture with different collection times (1-3 days).

[0036] The bovine colostrum sample is diluted with distilled water, and the fat content dilution ratio is bovine colostrum: water=3:5, and the detection protein content dilution ratio is bovine colostrum: water=3:10, and the detection dry matter content dilution ratio is bovine colostrum Milk: water = 3:5. Heat the water bath to 40°C and mix with a vortex shaker. Fourier transform infrared full-spectrum scanning dairy component analyzer parameter selection "milk" test module and the indicators to be detected. Three parallel detections were carried out on the samples by a Fourier infrared full-spectrum scanning dairy component analyzer, and the actual content of the...

Embodiment 3

[0041] Embodiment 3, rapid detection physical and chemical index of bovine colostrum

[0042] Use the method of the present invention and the national standard method to detect and collect the bovine colostrum of the second generation of different pastures respectively, and the rapid method detection value of fat, protein, dry matter and the difference between the rapid detection value of each substance and the national standard detection value are made respectively 95 confidence interval plots. The results are shown in Table 5 below.

[0044]

[0045]

[0046]Using the MINITAB statistical analysis software, the rapid detection values ​​of random detection of fat, protein, and dry matter and the difference between the rapid detection values ​​and the national standard detection values ​​were respectively plotted with 95 confidence intervals, as shown in Figure 3-1 to Figure 3-6 shown. From the confidence interval graph, it can be seen that the rapid ...

Abstract

The invention relates to the field of dairy products, in particular to a method for quickly detecting the content of fat, protein and dry substances in bovine coloctrum. The quick detection method of the invention comprises the following steps of: 1) diluting a bovine coloctrum sample with distilled water, wherein the dilution proportion for detecting the fat content is that the ratio of the bovine coloctrum to water is 3 to 5, the dilution proportion for detecting the protein content is that the ratio of the bovine coloctrum to the water is 3 to 10, and the dilution proportion for detecting the dry substance content is that the ratio of the bovine coloctrum to the water is 3 to 5; 2) detecting the sample by using an Fourier infrared full-spectrum scanning dairy component analyzer; and 3) multiplying an obtained detection result by the corresponding dilution ratio in the step 1). The method overcomes the disadvantages of long time and complicated steps of routine detection, can accurately determine the content of main indexes in the bovine coloctrum, provides a quick, simple and convenient method for factory acquisition of the bovine coloctrum, and is applied in the fields of quick acquisition and analytic detection of products.

Description

technical field [0001] The invention relates to the field of dairy products, in particular to a method for rapidly detecting the fat, protein and dry matter content in bovine colostrum. Background technique [0002] Bovine colostrum is the milk of dairy cows in the first few days after calving. Bovine colostrum is rich in biologically active substances and has high research value. These active ingredients make bovine colostrum improve gastrointestinal function; Infection of germs; Enhance the body's system immunity; Regulate the balance of the body's physiological state; Accelerate the process of health recovery and other unique physiological functions. Therefore, the research on bovine colostrum has attracted much attention in recent years. [0003] In the inspection process of bovine colostrum acquisition, the Gable method, Rhodes-Gothrie method, Babcock method, etc. are usually used for fat inspection; Kjeldahl method is often used for protein detection; water evaporatio...
