Ruminant animal-origin feedstuff identification method based on lipid Raman spectrums

Abstract

The invention provides a ruminant animal-origin feedstuff identification method based on lipid Raman spectrums. The ruminant animal-origin feedstuff identification method includes the steps that animal-origin feedstuff with known origins and of different species are collected; lipid samples are extracted; Raman spectrum information data of the lipid samples are collected, and the spectrum range is 400-3600 cm<-1>; a distinguishing and analyzing model of the ruminant animal-origin feedstuff is built; the built distinguishing and analyzing model is evaluated; lipid samples of the animal-origin feedstuff to be detected are extracted, and the Raman spectrum information data are collected and input into the distinguishing and analyzing model for species identification. The Raman spectrums of the lipid samples are directly collected, spectrum information and species origin information are correlated, the ruminant animal-origin feedstuff can be identified and analyzed fast and effectively, the analyzing requirement for species identification of the ruminant animal-origin feedstuff of feed quality safety supervision in China is met, and it can be ensured that while 'bovine spongiform encephalopathy' is efficiently prevented, and sustainable development and cyclic utilization of the feed industry are effectively implemented.

Description

technical field [0001] The invention belongs to the field of identification of animal-derived feed, in particular to a method for identifying and analyzing animal-derived feed raw materials by using Raman spectroscopy. Background technique [0002] Mad Cow Disease (Bovine Spongiform Encephalopathy) is a zoonotic disease whose pathogenic prion can be transmitted through the food chain. Meat and bone meal is an animal-derived protein feed made from non-edible tissues after slaughtering livestock and subjected to high-temperature treatment. It has the characteristics of rich protein content and has been widely used in the feed industry. Studies have shown that mad cow disease is caused by feeding ruminants with meat and bone meal from sick cattle, sheep and other animals. In order to prevent the spread of mad cow disease, countries around the world have formulated relevant laws and regulations to restrict or prohibit the use of animal-derived feed such as meat and bone meal. ...

Problems solved by technology

The existing near-infrared spectroscopy technology is based on the detection of raw materials. It is a rapid detection method, but the detection accuracy is relatively low, and it also has certain limitations in the identification and analysis of species.
