[0035] Instruments and reagents:

[0036] Instruments: Ultrasonic generator, disposable syringe (2mL, equipped with organic filter membrane), analytical balance, gas chromatography-tandem triple quadrupole mass spectrometer.

[0037] Reagents: chromatographically pure acetonitrile, tert-butyl-4-hydroxyanisole standard.

[0038] A method for assaying tert-butyl-4-hydroxyanisole in a dry food simulant, comprising the following steps:

[0039] Step 1. Add 50mL of acetonitrile to a 150mL Erlenmeyer flask with dry food simulants, and sonicate at 50°C for 30min. After ultrasonicating the filter residue with 50mL of acetonitrile at 50°C for 30min, combine the filtrates and concentrate to a certain volume V. 0.2μm organic filter membrane is used as the test solution;

Abstract

The invention relates to a method for the determination of tert butyl-4-hydroxy anisole in a dry food simulant, and belongs to the technical field of analysis and detection. The method for the determination of the tert butyl-4-hydroxy anisole content in the dry food stimulant is established, the dry food stimulant is directly injected after extraction filtration for gas chromatography-tandem triple quadrupole mass spectrometry (GC-MS / MS) analysis, the step is simple, and degree of automation is high. Based on optimized pretreatment conditions of the method and set optimal chromatography-mass spectrometry parameters, the tert butyl-4-hydroxy anisole content in the dry food stimulant can be accurately measured, and the method has the advantages of strong anti-interference, high accuracy of quantitative results, good reproducibility and detection limit low to 0.01mg / kg.

Description

technical field [0001] The invention relates to a method for determining tert-butyl-4-hydroxyanisole in dry food simulants, belonging to the technical field of analysis and detection. Background technique [0002] Tert-butyl-4-hydroxyanisole (BHA, CAS No.: 25013-16-5) is an antioxidant that is added to plastic products because it can effectively delay the oxidation and decomposition of plastic products. For plastic products used in food contact, tert-butyl-4-hydroxyanisole may migrate from plastic products into food. tert-Butyl-4-hydroxyanisole has acute and specific target organ toxicity, and can cause skin and eye irritation. The "GB 9685 National Food Safety Standard Standards for the Use of Additives in Food Contact Materials and Products (Draft for Comment)" issued in 2015 stipulates that in plastic food contact materials and products, the specific content of tert-butyl-4-hydroxyanisole Migration should not exceed 30mg / kg. [0003] In the article "Simultaneous Determ...
