Food safety

The basis of food processing is the prevention of food safety hazards such as microbial, chemical or foreign material contamination.

Bühler is at the forefront of harnessing science and technology for reducing food safety risks in low-moisture food processing. Solutions focus on safeguarding the value of raw materials, achieving reliable microbial decontamination, detecting and removing foreign materials and ensuring hygiene and traceability in all steps of food production.

Food safety is the game changer for food manufacturers. Hardly a day passes without news on food that is contaminated, adulterated or has made people ill. We at Bühler have taken up the food safety challenge and are committed to innovations for safe feed and food processing across the value chain.

The strong focus on food safety is driven by growing global trade and increasing industrial food production. Also, progress in the detection of all sorts of contaminants leads to reassessment of food safety risks. On the other side, consumers’ trust in the agro-food industry is shaken by food safety alerts that sometimes go viral on social media. 

Safe raw materials


Food Safety starts with safeguarding the quality of raw materials. Mycotoxins are considered a major threat to humans and animals. These poisonous compounds are formed on crops by fungal molds, and climate change is promoting this hazard. Efficient post-harvest drying of grain effectively reduces mycotoxin formation. In addition, grain cleaning solutions allow mycotoxin removal at an early stage of the value chain. Optical sorting rejects the highly contaminated grain fractions, but also eliminates foreign material like wood, plastic or glass.

Hygienic design


Good hygiene is essential for good manufacturing practice (GMP). Bühler is member of the European Hygienic Engineering & Design Group (EHEDG) and places strong emphasis on hygienic design. An example of outstanding hygienic design is the new Bühler flaking mill; where the design ensures good accessibility for efficient cleaning. But hygienic design also means placing special care on the materials. Our new Diorit roller mill features corrosion-free stainless steel of parts that are in contact with the food. Another example is the Nova sifter. Its design and material selection reduce the risk of flour contamination. 

“A quarter of the grain crop is contaminated with dangerous mycotoxins. Sorting solutions from Bühler are a remedy for this problem.”

Beatrice Conde-Petit, Head Food and Feed Safety at Bühler

Eliminating harmful bacteria


Finally, the control of harmful bacteria calls for reliable kill steps for safe ready-to-eat products. This is a critical aspect in feed processing, because safe feed means healthy livestock and safe animal foods. Bühler has designed the pelleting of feed into a trusted kill step by combining expertise in engineering, process technology, automation and microbiology. And the journey goes on. Bühler fosters collaborative innovation to build the food safety solutions for today and tomorrow.
