Detection method for bamboo shoots

Abstract

The invention relates to a detection method for bamboo shoots. The detection method comprises the following steps: S1, cutting the bamboo shoots into a plurality of bamboo shoot slices along the radial direction of the bamboo shoots and selecting the bamboo shoot slices with the greatest rigidity from the plurality of bamboo shoot slices; S2, thinning the bamboo shoot slices with the greatest rigidity into minced bamboo shoot slices until the moisture content is 1 to 3 percent, and compressed the dried bamboo shoot slices into bamboo shoot blocks; S3, determining the content of a metal elementin the bamboo shoot blocks through an X-ray fluorescence spectrum analysis method, wherein the metal element is lead or chromium. According to the detection method provided by the invention, the content of the metal element in a unit volume in the bamboo shoot blocks is greatly improved, and the content of the metal element in the bamboo shoot blocks is determined through the X-ray fluorescence spectrum analysis method; the difficulty that the detection precision is low when the bamboo shoots are detected by a previous X-ray fluorescence spectrum analysis method is solved.

Description

technical field [0001] The invention relates to the technical field of food detection, in particular to a detection method for bamboo shoots. Background technique [0002] Bamboo shoots contain amino acids necessary for the human body, various trace elements and cellulose. It is a low-fat, low-sugar, high-protein, high-fiber green health food that is deeply loved by the public. However, with the intensification of industrial pollution, the heavy metal pollution in the soil has become more and more serious. The bamboo shoots that grow in the soil containing heavy metals contain a lot of heavy metals. After the heavy metals left in the bamboo shoots enter the human body, some harmful substances will accumulate in the body for a long time , induce certain diseases in the body, and pose a serious threat to human health. [0003] The current detection methods for heavy metals generally include chemical and physical methods. The existing chemical method detects the content of he...

AI Technical Summary

Problems solved by technology

The existing chemical method detects the content of heavy metals by chemical titration, which has high precision but complicated steps, so the detection cycle is long; the existing physical method detects heavy metals through metal detectors or X-ray fluorescence spectrometers. The detection speed has been greatly improved compared with the chemical method, but the metal detector cannot detect the specific content of heavy metals, and the X-ray fluorescence spectrometer has certain requirements for the content of heavy metals. Usually, the content of heavy metals in bamboo shoots is lower than that of X-rays. Fluorescence spectrometer has requirements for metal content, so X-ray fluorescence spectrometer is used to detect the content of heavy metals in bamboo shoots, and the detection accuracy is revealed
