Abstract

The invention discloses a quick detection method for 58 types of allergenic fragrance in children products. The quick detection method comprises the following steps: carrying out preliminary treatment on a sample, smashing the sample, evenly mixing, putting a proper quantity of samples into a 44-bit automatic headspace sampler, or extracting by solvent, putting the extracted solution into the 44-bit automatic headspace sampler, setting a headspace condition, volatilizing and transferring the allergenic fragrance to a gaseous phase, and introducing gas into a gas chromatography-mass spectrometer to realize detection, wherein the sample comprises velvet fabric, wooden and plastic samples. The quick detection method for 58 types of allergenic fragrance in children products has good linearity and high selectivity, sensitivity, accuracy and precision.

Description

technical field [0001] The invention relates to the field of inspection and quarantine, in particular to a rapid detection method for 58 kinds of allergenic fragrances in children's products. Background technique [0002] In the production process of children's products, spices or flavoring agents are often added, on the one hand to make them scented, thereby increasing their appeal to children, and on the other hand to cover up certain unpleasant tastes. Flavors and fragrances are usually composed of dozens to hundreds of organic compounds with aromatic odors. Not all of these compounds are safe and harmless, and some substances have strong allergens, so-called allergenic fragrances. Relevant studies have shown that at least 1-2% of people will develop allergic symptoms after exposure to fragrance substances, such as asthma, rhinitis and other respiratory diseases, headaches, mucosal symptoms, itchy dermatitis, etc. When products containing allergenic substances are played...
