Food Analysis
The long-term market success of food and the associated product brands depends to a large extent on their quality and safety, because consumers perceive and remember the quality or quality flaws of food in a very sensitive way. We protect your brand for you as a food manufacturer or retailer and support you in meeting legal requirements by testing the quality and safety of your products in our accredited laboratories. Therefore we provide all methods of modern food analysis: from chemical-physical analysis to sensory tests to microbiological and molecular biological analyses and the identification of foreign bodies. Our competent experts will advise you comprehensively in the planning of sampling and analysis. The efficient and reliable analysis of WESSLING supports food manufacturers and suppliers of raw materials in complying with legal requirements and ensures the highest standards in the field of food safety. |

Our range of services:
Chemical-phsical analysis (including nutritional analysis, additives, authenticity verfication, food fraud detection, undesirable ingredients, key figures, histological tests, identification of foreign bodies)
Microbiology analysis (including hygiene indicators, spoilage organisms, identification of microorganisums, pathogenic microorganisms, studies for minimm shelf life)
Residue and contaminants (including mycotoxins, Dioxins and polycyclic biphenyls, heavy metals, polycyclic aromatic hydrocarbons (PAHs), quaternary ammonium compounds, phthalates, process contaminants, acrylamide)
Sensory test (including descriptive tests, suitability tests for human consumption, difference test, triangel test, popularity test)
Molecular biological analysis (including animal species determination, genetically modified organisms(GMO), allergens, bacteriotoxins, proof of risk material(CNS）
Identification of foreign bodies:
Documentation of dimensions
Photographic documentation of buildup or striking deformations
Visual inspection for a rough classification of the material
Light microscopic examination of biological materials and powdery foreign bodies to identify amorphous or crystalline structures
FT-IR spectroscopy for a non-destructive examination of plastics, e.g. foils, or hard plastic particles
ATR technology to identify the type of polymer and additives, e.g. plasticisers for homogeneous materials
EDX to identify glass particles, metallic or mineral foreign bodies or other predominantly inorganic particles, identification of elements from atomic number 5 (boron), quantification from atomic number 11 (sodium)
SEM images for further information on the microstructure of a foreign body
X-ray fluorescence analysis (XRF) or mass spectrometry with inductively coupled plasma (ICP-MS) to examine element composition
Molecular biological analysis of animal or plant fragments, either via species-specific polymerase chain reaction (PCR) or via PCR-RFLP (restriction fragment length polymorphism)
