Embodiment Construction

[0033] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Such as figure 1 As shown, the invention provides a method for detecting terrestrial animal fat components in fish oil, comprising:

[0035] S1: Collect known terrestrial animal oil samples of different species, and mix the pure fish oil samples of the species to be tested with the terrestrial animal oil samples evenly;

[0036] S2: collecting the infrared spectrum data information of the mixed oil samples;

[0037] S3: According to the corresponding relationship between the infrared spectrum data information and the mixed oil sample, establish a qualitative discriminant analysis model for terrestrial animal oil in fish oil;

[0038] S4: Obtain the infrared spectrum data information of the fish oil to be tested, and determine whether the fish oil to be tested contains the corresponding terrestrial animal oil through the inversion of the pre-esta...

Abstract

The invention relates to a method for detecting terrestrial animal fat components in fish oil. The method comprises the following steps: S1: collecting terrestrial animal fat samples with different known species, and uniformly mixing a pure fish oil sample of the to-be-detected species with the terrestrial animal fat samples respectively; S2: acquiring infrared spectrum data information of the mixed fat samples respectively; S3: according to a corresponding relation between the infrared spectrum data information and the mixed fat samples, establishing a qualitative distinguishing analysis model of the terrestrial animal fat in the fish oil; and S4: acquiring the infrared spectrum data information of the fish oil to be detected, and determining whether the fish oil to be detected contains the corresponding terrestrial animal fat or not through inversion of the distinguishing analysis model according to the infrared spectrum data information of the fish oil to be detected. With the adoption of the scheme provided by the invention, difference properties of the fat samples with the different species can be directly and remarkably represented, and the method has the advantages that a few of the samples are needed, the operation is simple and convenient, the measurement speed is rapid and the like, and the rapid and effective distinguishing analysis of the different terrestrial animal fat components in the fish oil is realized.

Description

technical field [0001] The invention relates to the field of identification and analysis of animal-derived feed components, in particular to a method and system for detecting terrestrial animal oil components in fish oil. Background technique [0002] Animal fat is made from by-products such as fat, skin, and viscera of meat processing plants, which are processed or extracted under heat and pressure. These animal fats are often used as additives for fish oil, lard, tallow, or poultry oil . Fish oil, lard, tallow or poultry oil are often used as ingredients in livestock and poultry animal feed. As a high-quality high-energy feed, oil addition has been widely used in livestock and poultry feed, and has become an effective means to promote animal growth and improve feed conversion efficiency. At the same time, in view of the impact of mad cow disease, the "Regulations on the Administration of Feed and Feed Additives" issued by my country in 2013 clearly stipulates that it is ...
