Embodiment 1

[0029] Instruments and equipment:

[0030] MilkoScan produced by FOSS company TM 7RM milk composition detector (according to the product instruction manual).

[0031] The operation steps are as follows:

[0032] 1) Select a milk sample:

[0033] 60 samples of fresh mare's milk and 60 samples of fresh cow's milk were collected respectively.

[0034] 2) Mid-infrared spectrum collection:

[0035] Pour horse milk and cow milk samples into cylindrical sampling tubes with a diameter of 3.5cm and a height of 9cm to ensure that the liquid level is greater than 6cm, and then bathe them in a water bath at 42°C for 15-20min, and then extend the solid optical fiber probe. Aspirate a sample into the liquid for detection, using MilkoScan from FOSS TM 7RM milk composition detector at 4000-400cm -1 The mare's milk and cow's milk samples are scanned within the wavenumber range, and the light transmittance corresponding to the sample is output by the computer connected to it to obtain the...

Abstract

The invention belongs to the field of milk product analysis, and particularly relates to a methodfor quickly identifying milk and mare milk, which is relates to intermediate infrared spectroscopy. The method comprises the following steps: 1) taking fresh mare milk and milk samples; 2) scanning the samples in anintermediate infrared spectral range to obtain intermediate infrared spectral data; 3) preprocessing the original intermediate infrared spectrum to remove abnormal values; 4) dividing the preprocessed data set into a training set and a test set according to a stratified sampling principle; 5) performing dimension reduction processing on the training set to improve the model training speed; 6) on the training set, establishing a model for distinguishing mare's milk from milk through 10-fold cross validation by using algorithms such as a nearest neighbor algorithm, and evaluating and screening the model by using accuracy, specificity, sensitivity and AUC; and 7) estimating the generalization performance of the optimal model.

Description

technical field [0001] The invention belongs to the technical field of milk product analysis, and in particular relates to a rapid identification method for identifying cow's milk and mare's milk. The present invention is related to the field of analysis using infrared spectroscopy to identify ingredients in dairy products. Background technique [0002] The content and ratio of protein, amino acid, lactose and minerals in mare's milk are close to those of breast milk, which is easier for infants to absorb and reduces allergic symptoms [1,4,8] . And mare's milk is rich in vitamins and minerals, these components participate in the metabolism of the human body, have the effects of regulating human physiological functions, improving human immunity and preventing and curing diseases, unsaturated fatty acids and low molecular fatty acids are effective in preventing hypercholesterolemia and arteriosclerosis good effect. Free glycans in mare's milk have a wide range of biological...
