Method for identifying abalone origin by atomic absorption spectrum

Abstract

The invention provides a method for identifying abalone origin by utilizing atomic absorption spectrometry, comprising the following steps: A. establishing an origin abalone element reference database, that is, using Cultured abalone of Distribution in the same waters as origin standard products, measuring the contents of kalium, sodium, magnesium, calcium, zinc, and iron elements contained in the abalone as data of the element content database of the origin abalone by utilizing atomic absorption spectrometry; B. identifying samples, that is, respectively detecting the abalone samples to be identified with the standard products under the same conditions, so as to obtain the contents of kalium, sodium, magnesium, calcium, zinc, and iron elements contained in the abalone, and identify whether existing significant difference and judge whether the abalone belongs to the origin by comparing statistically the element contents of the standard products and the origin abalone. Because the origin abalone element reference database established in the invention contains wider range, the analysis results by comparing the abalone to be identified and the database is not influenced by subjective sense, thereby providing an objective assessment criteria which has the characteristics of convenience, quickness, simple operation, and high accuracy.

Description

technical field [0001] The invention relates to a method for identifying the origin of abalone by atomic absorption spectroscopy, which belongs to the technical field of spectral analysis. Background technique [0002] Abalone is a single-valve mollusk that crawls on rocks below the low tide line in shallow seas. It is a precious seafood with delicate meat and delicious taste, and is known as the "crown of seafood". Because the aquatic environment of a specific place of origin is closely related to the nutrient composition and content of abalone. Therefore, the price of abalone from well-known origins is also higher than that of other origins. At present, there is no detection method to identify the origin of abalone in my country. The existing literature reports on the detection of abalone mainly detect harmful heavy metals, pesticide residues, and limited nutrients. , there is no literature report for the purpose of identifying the origin of abalone, and it is impossible t...
