As the saying goes, 'people take food for the sky, food is safe for the first', food safety is related to the peace and happiness of thousands of households, which is related to the harmonious and stable society. It is imperative to comprehensively improve and guarantee food safety. According to relevant statistics, Cancer patients continue to rise. Every year or personally, bad habits and diet are two important factors. So, let's take a look at the foods that have carcinogens in life, and how the relevant food testing instruments protect people' Good food on the tip of your tongue!
Insiders pointed out that 'benzopyrene' food, 'aflatoxin' food, nitroso compounds, etc. are to some extent a food that produces carcinogens. First, 'benzopyrene' food, mainly including barbecue, Fried foods and cigarettes. Some people may not know that barbecued and fried foods during the production process are not allowed to produce 'benzopyrene' carcinogens during the production process, in which the charred parts of the 'benzene And the content will increase by more than 10 times. Therefore, consumers should eat fried and grilled foods as little as possible. For 'aflatoxin' foods, mainly bitter black nuts, moldy corn and millet, mildew Bacon and so on.
We know that aflatoxin is very tenacious, and it is difficult to kill toxins even after boiling water treatment. At the same time, it is highly toxic. Its toxicity is more than 60 times that of arsenic. It is a very strong mycotoxin carcinogen. It is recommended that those moldy fruits, nuts, pastries, bread, taro, bean curd, bean paste and other foods should not be risky. There are also nitroso compounds, mainly smoked foods, preserved foods, pickles, kimchi, etc. Because the food is in the process of curing, improper treatment will produce nitroso compounds, these nitroso compounds can be converted into nitrous carcinogens after entering the human body.
Then, in the face of the temptation of 'food' in life, there are carcinogens. In addition to mastering the correct processing methods and suggesting that people reduce their consumption, is there any other way to deal with it? Industry experts say that at present, relevant departments will Sampling people's food on the table, through advanced food testing equipment, can quickly and accurately analyze whether the product contains benzopyrene, acrylamide, nitrosamines, aflatoxin, peroxide value and other substances to ensure people Diet safe.
It is estimated that about 20% of the world's food crops are contaminated by strong carcinogens in molds. For this reason, in our daily life, some grains, nuts and dried fruits, a small amount of aflatoxin are almost inevitable. Currently, the market is highly efficient. Liquid chromatography-fluorescence detection and liquid chromatography-mass spectrometry, thin layer chromatography, enzyme-linked immunosorbent assay and aflatoxin detector can be used for the detection of aflatoxin in food.
In general, the aflatoxin detector uses a special LED light source and a fixed optical path to work. The detection results are accurate and reliable. At the same time, the sample can be detected without derivatization. It has high sensitivity and accuracy, and rapid analysis capability. It has been widely used. Food, food, edible oil, dairy products, pharmaceuticals, feed and other production and processing fields. Recently, at the '5th China Analytical Instrument Academic Annual Meeting', some companies have introduced aflatoxin fluorescence detectors to replace pulses with low-power LEDs. Xenon lamp as a light source greatly improves the life of the light source. More importantly, the detection is convenient, fast, accurate, and the detection sensitivity is better than similar foreign products.
For the detection of peroxide value of edible oil, it is commonly used in edible oil analyzers, peroxide value detectors, edible oil acid value peroxide value measuring instruments and other testing instruments. However, recently, a research and development team of a university in Hefei realized three-dimensional Gold nanorod array self-assembly, preparation of metal-like liquid nano-array substrate, successfully developed a new liquid-enhanced Raman spectroscopy quantitative analyzer, effectively solving the bottleneck problem of practical application of quantitative technology analysis, which can cause cancer in food Application in the field of detection and analysis of quality and safety of foods such as edible oil and peroxide value.
In addition, the oil phase spectral fingerprint peak of the active substrate of the novel liquid enhanced Raman spectroscopy quantitative analyzer is sharp and stable, and the acquired spectral signal is normalized according to the oil phase fingerprint peak, which not only effectively corrects the excitation volume, nanosol, High-sensitivity, multi-component, two-liquid phase, quantitative liquid analysis can be achieved by laser focusing, temperature and sample microenvironment. It can ensure accurate and effective detection.
It can be seen that although the World Health Organization has published 'first-class carcinogens', it is also a 'carcinogenic pioneer', including several types of carcinogenic foods mentioned above, but it is also difficult to stop many food lovers from eating 'unscrupulously'. This requires relevant departments and food production and processing enterprises to strengthen supervision, testing, the use of advanced testing methods, the use of testing equipment to protect people's 'good food on the tongue' quality and safety.
