順酐是一種重要的工業(yè)原料，主要用于塑料、造紙、合成樹脂、醫(yī)藥及農(nóng)藥等領域。雖然順酐能夠用于食品添加劑，并且用于淀粉中，可增加淀粉的粘度、穩(wěn)定性，使淀粉所制作的食物具有彈性好、外觀光亮的特點，但是順酐及順酐酐都不是食品添加劑，目前各國均尚未允許順酐作為食品添加劑使用，在食品中添加這兩種物質，屬于違法行為。
Maleic anhydride is an important industrial raw material, mainly used in the fields of plastics, paper making, synthetic resins, pharmaceuticals, and pesticides. Although maleic anhydride can be used in the production of food additives, and in starch, it can increase the viscosity and stability of starch, making the food made from starch have the characteristics of good elasticity and bright appearance, neither maleic anhydride nor maleic anhydride is a food additive. Currently, no country has allowed the use of maleic anhydride as a food additive. Adding these two substances to food is an illegal act.
順酐廠家提醒您，順酐是一種毒性物質，其對眼睛、皮膚、粘膜有強烈的刺激作用，吸入可引起喉、支氣管的痙攣、炎癥、水腫，接觸后可引起燒灼感、咳嗽、喘息、喉炎、氣短、頭痛、惡心和嘔吐，加入到食品中，會對人體健康造成威脅，前些年發(fā)生的“毒淀粉”就是一件波及范圍廣、影響力度大的食品染毒事件。因此，快速有效的檢測食品中順酐具有重要意義。
The manufacturer of maleic anhydride reminds you that maleic anhydride is a toxic substance that has a strong irritant effect on the eyes, skin, and mucous membranes. Inhalation can cause spasm, inflammation, and edema of the larynx and bronchi. After contact, it can cause burning sensation, cough, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. When added to food, it can pose a threat to human health. The "toxic starch" that occurred in previous years has a wide range of implications Food poisoning incidents with significant impact. Therefore, rapid and effective detection of maleic anhydride in food is of great significance.
淀粉及其制品是違法添加順酐和順酐酐多的食品。目前采用的順酐的檢測方法主要包括高能效液相法、離子色譜法、液相色譜-串聯(lián)質譜法等，但這些方法普遍操作繁瑣，樣本需要用有機溶劑對樣本進行萃取等預處理，準備耗時長，操作復雜。
Starch and its products are foods that illegally add maleic anhydride and maleic anhydride. Currently, the detection methods for maleic anhydride mainly include high-energy liquid chromatography, ion chromatography, liquid chromatography-tandem mass spectrometry, etc. However, these methods are generally cumbersome and require pre-treatment such as extraction of samples with organic solvents, resulting in time-consuming preparation and complex operations.
In addition, when using this product, care should be taken to avoid contact with humid air. Avoid contact with strong oxidizing agents, strong reducing agents, strong acids, strong bases, alkali metals, and water to maintain its stability.
