Baijia.net - a professional third-party testing and inspection platform that provides testing services for general physical and chemical items of food
Physical and chemical tests mainly include the determination of physical and chemical indicators such as water quality or food, excluding the detection of tuberculosis, AIDS and other infectious diseases. There are safety issues in all laboratories of the Center for Disease Control and Prevention. In addition to biological safety, physical and chemical laboratories have the possibility of poisoning by chemical reagents, reaction products, toxins, etc., and must possess relevant knowledge. Responsible CDCs will receive pre employment training
Physical and chemical testing includes two aspects, namely, testing the sample through physical and chemical methods, which can also measure a lot of useful data. The detection of physical indicators includes the weight, size, and density of the product. These indicators can be directly measured by instruments and the results are also very fast. However, to ensure the reliability of the results, it is necessary to test more samples and then calculate the average value through statistical methods. In addition, physical testing also includes some relatively complex methods, such as detecting the sugar content in fruit juice. The commonly used method is to detect the refractive index of the sample, which can infer the sugar content, so it is also a physical method
Chemical testing in food testing technology covers more content, as many components cannot be directly measured through physical methods and must be tested through chemical experiments.
. For example, the various organic components contained in food, whether they are beneficial nutrients for humans, health ingredients that have an impact on the body, or toxic substances that are harmful to humans, many of them need to be extracted through chemical methods or inferred through the detection of other relevant indicators
What are the common tests for food physicochemical items
First, loss on drying, residue on ignition, moisture, ash content, infrared identification, optical rotation, density, net content, specific volume, expansion rate, acid value, peroxide value, etc.
Second, mineral elements: calcium, phosphorus, potassium, sodium, magnesium, etc., iron, zinc, chromium, manganese, cobalt, nickel, fluorine, iodine, selenium, etc.
; 3、 Carbohydrates: total carbohydrates, monosaccharidestrisaccharides, disaccharides, oligosaccharides, polysaccharides; Total protein essential amino acids: lysine, methionine, leucine, isoleucine, threonine, valine, tryptophan, phenylalanine Non essential amino acids: glutamate, alanine, glycine, aspartate, cystine, proline, serine, and tyrosine
4. Toxic and harmful substances: nitrite, melamine, benzopyrene, aflatoxin, sulfur dioxide, ochratoxin A, sulfur dioxide residue, volume residue, malondialdehyde, polychlorinated biphenyls, polybrominated biphenyls, nonylphenol, triphenyl phosphate, polychlorinated naphthalene, etc
