Embodiment 1

[0050] A fingerprint detection method for the freshness of abalone viscera, comprising the following steps (carrying out 10 groups in the same batch for processing and detection):

[0051] (1) Perform HS-SPME-based pretreatment on the abalone viscera samples: remove the viscera from the freshly bought abalone, homogenate and weigh the viscera, put each 0.3g portion into a ziplock bag, blow in nitrogen, A total of 15 samples were weighed, and the 0h test was carried out first on the 1st, and the remaining 7 samples were divided into two groups for storage in different groups. . 0h detection first: Weigh 0.3217g visceral homogenate into a 4mL headspace bottle, add 1.4mL saturated saline, preheat at 30°C for 10min, push the SPME handle to insert the fiber head of the extraction head into the headspace bottle, Then place it on a magnetic stirring heater with an equilibrium temperature of 80°C and a rotation speed of 90 rad / min, keep it for 40 minutes, retract the extraction fiber...

Abstract

The invention relates to a fingerprint chromatogram detection method for fresh degree of abalone viscera. The fingerprint chromatogram detection method includes the steps: taking the abalone viscera as raw materials; cleaning the abalone viscera, and performing pulping for the cleaned abalone viscera; detecting components of the abalone viscera at corruption phases of different degrees by the aid of a headspace-solid-phase micro-extraction / gas chromatography-mass spectrometry technologies according to vacuum freezing and drying technologies; analyzing chromatogram information of the abalone viscera by the aid of a PLS-DA (partial least squares-discriminatory analysis) method to obtain results, and applying the results to fish oil extraction process of various marine products and identification of various marine products of different varieties and different production places. The method is applicable to preprocessing stages of production of various fish oil and used for improving generation quality of various fish oil, slowly solving the problem of current intense food safety and facilitating healthy and sustainable development of food health care industries, tailings of aquatic products are sufficiently used, resources cannot be wasted, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to the field of deep processing and quality control of aquatic products, in particular to a fingerprint detection method for the freshness of abalone viscera. Background technique [0002] Fish oil is an extract derived from deep-sea fish fat and belongs to fish lipids. Phospholipids contained in fish oil are indispensable components of animal brain, nerve tissue, bone marrow, heart, liver, egg and spleen, and are also helpful for the digestion, absorption, transport and formation of lipids, and are also important structural substances for biofilms. Fish oil is rich in omega-3 polyunsaturated fatty acids (DHA and EPA), which can reduce low-density lipoprotein cholesterol in human blood, reduce blood viscosity, regulate blood lipids, prevent blood coagulation, prevent cerebral thrombosis, cerebral hemorrhage and Stroke, anti-inflammatory and other health benefits. [0003] Abalone is rich in nutrients and ranks as one of the "Eig...
