What does food testing generally test?

Generally, physical and chemical items, pollutants, mycotoxins, food additives, pesticide residues, veterinary drug residues, illegal additions, special food functional ingredients, animal-derived ingredients, labels, etc. are detected. ;

1. Physical and chemical items: moisture, ash, protein, fat, acid value, peroxide value, volatile basic nitrogen, soluble solids, total solids, skimmed milk solids, alcohol content, sulfur dioxide, relative density, pH value, specific rotation, refractive index, particle size, net content, etc.

2. Pollutants: lead, cadmium, mercury, arsenic, tin, nickel, chromium, nitrite, nitrate, benzo [a] pyrene, N- dimethylnitrosamine, polychlorinated biphenyls, etc.

3. Mycotoxins: aflatoxin, deoxynivalenol, patulin, ochratoxin A, zearalenone, etc.

4. Food additives: preservatives (benzoic acid, sorbic acid, dehydroacetic acid, etc. ), antioxidants (butyl anisole BHA, dibutylhydroxytoluene BHT, tert-butyl hydroquinone TBHQ, etc. ), colorants (lemon yellow, sunset yellow, carmine, brilliant blue, amaranth, magenta, erythrosine, etc. ), sweeteners (saccharin sodium, acesulfame K, etc. ).

5. Pesticide residues: pesticide residues such as dichlorvos, DDT, HCH, carbofuran, methamidophos, malathion and dieldrin, such as organophosphorus, organochlorine, pyrethroid and carbamate;

6. Veterinary drug residues: residues of clenbuterol, salbutamol, ractopamine, chlortetracycline, chloramphenicol, malachite green, nitrofurans, enrofloxacin, ciprofloxacin and other hormones, fluoroquinolones, tetracyclines and sulfonamides;
