The problem of plasticizers (phthalates) related to Baijiu products is a hot issue in the current Baijiu industry. The Chinese Baijiu Association analyzed that: through the determination of a large number of * * * * of * * * Baijiu products, Baijiu products basically contain plasticizer ingredients, * * 2.32mg/kg (about 8 times more than the national regulations), * * * 0.495mg/kg (about 1.7 times more than the national regulations), with an average of 0.537mg/kg (about 2 times more than the national regulations). Among them, the content of * * Baijiu is high, and the content of low-grade Baijiu is low. Plasticizer, also known as plasticizer, is a colorless, odorless liquid widely used in industry as a polymer material additive. Since May 2011, six types of phthalate plasticizers, including DEHP, DINP, DNOP, DBP, DMP, and DEP, have been detected in Taiwanese food, and DIDP has been detected in pharmaceuticals. Since then, the "haze" effect of plasticizers has continued to spread. After drinks, Baijiu, convenient food and drugs have been exposed to exceed the standard of plasticizers, their lethality has caused many people to talk about "plastic" discoloration. Excessive levels of plasticizers in food can pose serious harm to the human body. Long term intake of plasticizers can disrupt endocrine disorders, increase liver and kidney burden, cause chronic damage to the immune system, digestive system, and even lead to liver cancer. Its toxicity is 20 times that of melamine. On June 1st last year, the Ministry of Health urgently issued a notice to include phthalates (also known as phthalates) in the list of non edible substances that may be illegally added to food and food additives that are prone to abuse.

Referring to the national standard for the detection of plasticizers in food, the company has absorbed internationally leading chromatographic analysis technology,Committed to developing gas chromatography solutions for food quality analysis and testing, focusing on the detection of plasticizers in various common foods,According to the countryDetermination of Phthalates in Food (GB/T21911-2008)，**Time developed routine and rapid detection schemes for plasticizers in Baijiu---Gas Chromatography (GC)）The analytical method has the advantages of simple operation, * * speed, good repeatability, high sensitivity, and low instrument cost. It is one of the * * instruments for detecting plasticizers in various distilleries, companies, and laboratories in China,answerPlasticizer in Baijiu—Phthalates (titanium esters) substancesof**analysisDetection has a widely leading position in the domestic chromatography industry.

5There is no current national standard for the detection of plasticizer (phthalate) in Baijiu, The testing for this mainly refers to the national standardGB/T21911-2008Determination of Phthalates in Food. This standard applies to food16Plant phthalates. The detection limit of each phthalate compound in oil containing samples is1.5mg/kgThe detection limit of each phthalate compound in the oil-free sample is0.1mg/kgThe detection repeatability is not greater than3%At the same time, it complies with the "Health Office Supervision Letter" issued by the General Office of the Ministry of Health（2011）551The residual amount of phthalates specified in the document "No."0.3mg/kg.
