example

[0118] Examples of amino acid and fatty acid fingerprint data analysis, modeling and validation of Mongolian horse, goat and Bactrian camel milk, and cow raw milk and UHT milk.

[0119] (1) Sample amino acid and fatty acid fingerprints

[0120] Figure 3A , Figure 3B The collected amino acid and fatty acid fingerprint data (sets) of Inner Mongolia horse, goat and Bactrian camel milk, as well as cow raw milk and UHT milk are shown. In this modeling, 18 amino acids and 12 fatty acids (unknown fatty acids were not included) and their contents were retained.

[0121] Among them, C1, Species classification: 1 cow milk, 2 goat milk, 3 Mongolian horse milk, 4 Bactrian camel milk, 5, 6 and 7 are horse milk mixed with 10%, 25% and 50% cow milk respectively.

[0122] C2, Category1 is a subdivision, which is used in this example for subdivision identification model research, such as SIMCA and PLS-DA model building. 1 is a pure special milk (real milk), in this example is horse milk, 2...

Abstract

The invention discloses an authenticity identifying method and an authenticity identifying system for raw milk or liquid milk. The method comprises the following steps: performing amino acid fingerprint, fatty acid fingerprint or fatty acid gas chromatography fingerprint collection on a collected training sample set of a raw milk or liquid milk sample, performing data structure analysis by chemical metrology software, and constructing a qualitative and quantitative identification model; meanwhile, performing amino acid fingerprint, fatty acid fingerprint or fatty acid gas chromatography fingerprint collection on a milk sample verification sample set, inputting the acquired data into the constructed qualitative and quantitative identification model to verify the accuracy and the stability of the model, and performing model optimization until the accuracy of the model meets the requirement; finally identifying the authenticity of the raw milk or the liquid milk by the optimized identification model. The method can be used for identifying the authenticity of the milk sample accurately and reliably.

Description

technical field [0001] The invention relates to the technical field of milk processing, in particular to a method and system for authenticating raw milk or liquid milk. Background technique [0002] While my country's cattle and goat milk industry is developing, animal milk (special milk) such as horses, camels, yaks and buffaloes has gradually been commercialized. Special fresh milk, sterilized liquid milk, fermented milk, cheese, milk skin, milk wine and Specialty products such as breast fans have begun to be sold in supermarkets, specialty stores or Mongolian and Tibetan hospitals in big cities. Due to the small supply of special milk, unique flavor, high nutritional value and health care function, special milk products are often in short supply, and the price of raw milk is several times or even ten times higher than that of cow and goat milk. From 2013 to early 2014, the price of fresh milk in my country’s main milk-producing areas was 3.5-4.5 yuan / kg. According to our ...
