Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] The main steps of extracting taurine from seafood include water extraction, concentration, ion exchange resin adsorption, desorption, concentration and drying, etc., and all steps are liquid operations.

[0027] 1) Collection of samples: collection and preprocessing of calibration sample sets

[0028] Take 293 samples of each process stage in the taurine extraction process as a calibration sample set, so that the taurine content distribution in the sample has a certain range. After the above-mentioned samples are filtered with a needle filter with a pore size of 0.45um, each sample is divided into Two parts, one part of the sample is measured by near-infrared spectrum, and the other part of the sample is measured on the amino acid analyzer to measure the content of taurine in the sample.

[0029] 2) Near-infrared spectrum detection:

Abstract

The invention relates to a rapid detection method for taruine content in a marine product processing process. The rapid detection method is characterized by comprising the following steps: (1) collecting extracted liquid samples in the various stages in the taurine extracting process, wherein each sample is divided into two parts, the near infrared spectrum of one sample is measured, and the taurine content of the other sample is measured by an amino acid analyzer; (2) detecting the near infrared spectrums of the samples; (3) measuring the taurine contents of the samples; (4) establishing a regression prediction model; and (5) predicting the taurine contents of the samples by using the regression prediction model. According to the rapid detection method, the near infrared spectrum of the extracted liquid is measured, the taruine content of the extracted liquid can be rapidly obtained by utilizing an established calibration model; compared with the conventional amino acid analysis method, the rapid detection method has the advantages that the analysis time is greatly shortened, the amount of the reagent is saved, and the precision of the predication result is high.

Description

technical field [0001] The invention relates to the field of food detection, in particular to a rapid detection method for taurine content in waste materials such as leftovers and cooking liquid in the seafood processing process. Background technique [0002] The chemical name of taurine is 2-aminoethanesulfonic acid, which is a sulfur-containing non-protein structural amino acid that exists in a free form in the body. Soluble in water, insoluble in ethanol and ether, stable to heat. Studies have shown that taurine can promote brain development, enhance vision, regulate the excitability of nerve tissue, increase myocardial contractility, and promote the digestion of lipids. Therefore, it is widely used in the fields of health food and medicine. At present, the main source of natural taurine is extracted from seafood, and the determination of taurine in the extraction process mostly uses acid-base titration, thin-layer chromatography, high-performance liquid chromatography,...
