Det er bare så mye fantastisk man finner når man graver på nettet etter informasjon om dette fantastiske selskapet. Her er det problemet med meget helefarlig giftkonsentrasjoner i matvarer Tomras superteknologi løser. Utrolig imponerende! Utrolig signifikant! Legg merke til at Nestle fremheves som fornøyd bruker av teknologien. De er garantert ikke alene.

New concerns about aflatoxins in food can be circumpaed with technology

March 19, 2019

The contamination of food by aflatoxins, which can cause cancer, is worrying scientists and regulators. New concerns about these natural poisons, manifested earlier this year by scientific consultants, have provided an important warning of the risk to consumers ' health and the commercial risk to food companies.
Aflatoxins are a common problem found in cultivated plants or in foods stored in parts of Asia, Africa and the United States. This is because the toxins originate in two species of fungi that are favored by hot and humid climates. In February 2018, however, the European Food Safety Authority (EFSA) reported that there are also concerns about "the high levels of aflatoxin observed by some food products originating in European countries." Now There are appeals for EFSA to make its first full risk assessment of aflatoxins in more than a decade.

These concerns are not surprising: Aflatoxins are 68 times more lethal than arsenic and are able to seriously damage human and animal livers. Aflatoxins can cause fever, malaise and anorexia, followed by abdominal pain, vomiting and hepatitis. Even Worse, the chronic toxicity of aflatoxins can reduce immune efficiency and trigger cancer, which is why they are classified by the World Health Organization as a Group 1 Carcinogen. It is Known that exposure to aflatoxin-contaminated food has caused hundreds of deaths in India and Kenya, and many other fatalities have probably not been reported.

Even in Europe, where there are strict rules on food security, in 2013 several nations reported widespread contamination by aflatoxin of milk.


The best method for detecting aflatoxins is to choose to use sensor-based sorting machines, produced by TOMRA, a global technology pioneer to ensure food safety. TOMRA machines employ near-infrared spectroscopy (NIR), fluorescent lighting, and state-of-the-art lasers to analyze the surface structure and elemental composition of objects passing through a food production line. TOMRA's special Detox laser makes it possible to identify the extremely low intensity of light reflected by fungi in various types of food, allowing the detection of aflatoxin contamination.

In Addition to this extraordinary capability, TOMRA's sorting machines also utilize proprietary biometric signature Identification (BSI) technology. BSI digitized and detects the biometric characteristics of food – for example, nuts and raisins – and compares these features with resources stored in the machine database to determine whether items should be accepted or rejected. This detects and removes minor defects than is possible to be removed with conventional spectral technology. The accuracy of detection is so good that false rejection rates are exceptionally low and result in exceptionally high yields.

A good example of this technology can be seen in action in the Nestlé Group's processing line in Dongguan, China, administered by the Subbrand Hsufuchi Foods. Quality and safety are one of the ten corporate principles of Nestlé, which chose TOMRA as a strategic partner in combating aflatoxins contamination in peanut products. Since September 2016, Hsufuchi Foods operates two TOMRA Helius separation machines to achieve Nestlé 's global quality standards, which are stricter than China's domestic food safety regulations.

More than providing separators to combat aflatoxins, TOMRA also provides comprehensive support in machine configuration and optimization. To Validate the Nestlé Helius classifying machines with Detox technology, TOMRA's application support teams performed a six-month test on the Dongguan processing line, adjusting the classification parameters with more than 500 tonnes of Peanuts of different varieties. TOMRA also worked with Nestlé on quality inspection and invited a third-party inspection agency to define validation protocols, ensuring that the validation process and results were sufficiently representative.

Zhang Ahfung, assistant manager General in charge of production in Dongguan, said: "TOMRA technical support was very efficient and fast in response, both in the test phase and after the machine installation. Through Many tests, we are now certain that the TOMRA Helius classifier can effectively control the level of aflatoxin in Peanuts. It makes me calm, because I don't have to worry about the quality of our product anymore. Now, let's consider implementing a detox technology-based classifier at every facility where aflatoxin problems arise. "

Leading U.S. Supplier "surprised" with results

Small family businesses also benefit from TOMRA technologies. As An illustration of this, three examples of the Nimbus model sorting machine, each equipped with the laser module needed to detect aflatoxin, are used by the Damascus Peanut Company in the USA. This company specializing in peanut Husking employs approximately 125 people and manages its factory in Arlington, Georgia, 24 hours a day. This is the oldest operating factory of peanut husking in the country, but has remained at Front of the game by employing state-of-the-art equipment and TOMRA machines since 2002. The result is high quality peanuts, supplied to many famous food brands in Europe and Japan, as well as in the USA.

Damascus acquired the first TOMRA machine in 2002 with the intention of separating foreign material from its line, without the expectation that the machine could also classify the nuts contaminated by aflatoxin – but a pleasant surprise was on the way. The TOMRA machine was installed in Arlington during an unusual year, of low harvest quality and highly prevalent aflatoxin. When The final plots of the plant were tested for aflatoxin, the results were massively better than those in the other three plants in the group. This led Damascus to ask TOMRA if his machine also separated the aflatoxin.

TOMRA shared a peanut client using a TOMRA classifier, claiming that he had discovered how to remove aflatoxin with his machine. TOMRA requested that Damascus also check the materials rejected by the TOMRA classifier. Shortly Afterwards, the results of several chemical tests gave a first good indication that the machine was detecting and removing contaminated peanuts with aflatoxin. At This time, TOMRA has sent application engineers, laser specialists to Damascus, with the aim of refining the identification capabilities of aflatoxins of the machine, which have become fully reliable.

Bryan Willis, president of Damascus, explained: "Aflatoxin is an expensive problem for a peanut processor. Before we got TOMRA's machines, the only way to really deal with Aflatoxin was to "blanchear" the Peanuts. But compared to "Blancheamento", using a laser is much, much less expensive. Because of that, our machines have paid for themselves many times. And Of course the machines also do a great job of detecting and removing strange material, which is the reason why we originally bought them before discovering that they could classify something that humans can't see.

"At first, we were skeptical about the detection of aflatoxin by the machine. But then we begin to understand that the toxin is structurally different from the peanut. The Laser classifier looks at the toxin as if it were a piece of glass, metal or any non-peanut material. It Was very difficult for the industry to understand this initially, because that is how advances have occurred on existing technology. I'm Still impressed, but the evidence is in the results, and the aflatoxin problem has been solved. "

Bjorn Thumas, Director of Food Business Development at TOMRA Sorting Solutions, said: "What our machine does is equivalent to inspecting each grain, which is extremely necessary to ensure food safety. It Is clear that the system also performs other important sorting functions simultaneously, removing foreign material and removal of allergens from the line. And When handling maize for example, the laser can also differentiate between transgenic and non-transgenic seeds.

"Our machines increase productivity and improve throughput while providing protection against one of the biggest dangers the food industry faces. Aflatoxins are a potential killer – human and business – but we can keep them under control. "
