Food Analysis

Food Analysis


Food allergens are proteins in food which can trigger allergic, sometimes life-threatening, reactions in sensitized individuals. Often, very low food allergen concentrations are sufficient to cause allergic symptoms. Safe detection of even the smallest traces of an allergen in a final product is important for quality assurance in the food industry.


immunolab allergen kit


14 food ingredients are responsible for 90% of all food allergies and following EU Directive 2007/68/EC or 2000/13/EC, they must be reported on the package label when present in a product.

The Immunolab range of ELISA kits for the detection of allergens in food includes Spike Solutions to aid in internal quality control experiments.

BIOTECON Diagnostics produces foodproof® real-time PCR kits for the detection of allergens.

Mycotoxins (mould toxins) are secondary metabolism products from moulds which can cause a mycotoxicosis. Very low concentrations are sufficient to develop the toxic effects. The uptake of mycotoxins by mouldy foodstuffs can lead to damage of liver and kidneys, impairment of the immune system, damages to skin and mucosa etc. Some mycotoxins are even carcinogenic as they can cause genetic defects.

Aspergillus and Pencillium species grow under inadequate storage conditions of foodstuff. Typical resulting mycotoxins are Aflatoxins. Field fungi, like Fusarium, are generated in the field or by contaminations of the agricultural harvested crop. Typical mycotoxins are Fumonisin and Zearalenone.

Immunolab offers the following ELISA kits and immunoaffinity columns (IAC) for the detection and purification of diverse mycotoxins.


Antibiotics are divided in different groups according to their chemical structure and biological activity. The main groups are Beta-Lactams (Penicillin), Aminoglycosides (Streptomycin), Amphenicoles (Chloramphenicol), Sulfonamides, Makrolides, Nitrofurans and Tetracyclins.

The prophylactical use of antibiotics in animal foodstuff is either prohibited or subject of Maximal Residue Limits (MRL) according to the EU directive 2377/90.


Vitamins are organic compounds required for many essential vital functions of the organism. They are not produced by the body so they need to be ingested with our daily food on a regular basis. As a result more and more foods are enriched with vital vitamins in order to prevent a vitamin deficiency of the population. The declared vitamin concentrations have to be present until the end of the best-before use date. Overdoses should be avoided as well.

Vitamins are divided in the groups of water-soluble (B group and Vitamin C) and fat-soluble vitamins (E, D, K and A).


Hormones are abusively used as growth promotors in animal fattening. Their application should increase both weight gain and muscle meat share and simultaneously reduce the fat content.

Use of these drugs is prohibited in Europe but in other countries effective sexual hormone steroids are sometimes legally used as growth-stimulating substances in animal fattening. Abusive usage of the hormones and missing veterinary medical controls may lead to health risks for consumers.


Histamine is a biogenic amine which is formed by enzymatical decarboxylation from the amino acid histidine. It can enter the human digestive system via food consumption and trigger numerous intolerance related symptoms. The extent of the reaction depends on the ingested amount of histamine.

Furthermore, toxic reactions are possible after uptake of high histamine concentrations. These result from bacterial degradation of protein-rich food like fish, cheese and meat as well as from red wine consumption. The concentration of histamine formed depends on the bacterial species, temperature and exposure time.

Genetically Modified Organisms (GMOs)

Over one hundred different genetically modified plants are now grown in more than 29 countries worldwide. The main producing countries are USA, Brazil, Argentina, Canada and India. Soy beans are the most highly cultivated genetically modified plant, followed by corn, cotton and canola.

According to EU Regulation 1829/2003 and 1830/2003, the GMO content of more than 0.9% in foods and ingredients must be shown on the product label.

BIOTECON Diagnostics produce a wide range of real-time PCR kits for the detection and quantification of GMOs.
