Method for rapidly detecting plasticizer in beef tallow

Abstract

The invention relates to the field of plasticizer detection, and particularly relates to a rapid and accurate plasticizer detection method. The method takes animal fat as a detection object and mainlyaims at detection of a plasticizer in beef tallow, acetonitrile and n-hexane are taken as extraction solvents, the plasticizer in the beef tallow is extracted in an ultrasonic-assisted extraction mode, and after freezing treatment, the plasticizer in the beef tallow is obtained through centrifugation and rapid separation and extraction in a solidification state of the beef tallow. According to the method, the sample pretreatment mode in GB 5009.271-2016 is optimized, in the field of plasticizer detection of the animal fat, the pretreatment time can be shortened, the cost of SPE silica gel small columns can be reduced, consumption of a large number of reagents is reduced, and the detection result is accurate.

Description

technical field [0001] The invention relates to the field of plasticizer detection, in particular to a rapid detection scheme for plasticizers in tallow. Background technique [0002] Plasticizer, also called plasticizer, is a polymer material additive widely used in industry and a chemical agent often used in plastic products. Plasticizers are easy to dissolve into edible oils. When plastic packaging contains excess plasticizers, edible oils are likely to cause plasticizer pollution due to migration. Plasticizers are a kind of "environmental hormones" also known as "environmental hormones". The traces of such substances remaining in the environment enter the human body through the food chain to form false hormones, transmit false chemical signals, and affect the human body. Hormone content, and then interfere with the original mechanism of human endocrine, resulting in endocrine disorders. [0003] With the development of the hot pot industry, more and more people love ho...

The production of hot pot bottom ingredients includes butter, spices, peppers, watercress and other raw materials after frying. However, butter is the main raw material for hot pot bottom ingredients. From the production and processing of butter to the frying of butter hot pot bottom ingredients, Contact with plastic products in the production process, and easy to cause migration under high temperature conditions, eventually causing the content of plasticizers in butter and hot pot bottom materials to exceed the relevant national limit standards, bringing food safety risks to production enterprises
