The present invention relates to a method and a device useful for directly and rapidly quantifying the presence in milk of Aflatoxin M1, a carcinogenic mycotoxin deriving from Aflatoxin B1.
In particular conditions of humidity or high temperatures, some vegetable raw materials accumulate toxic fungi that produce a particular carcinogenic and toxic mycotoxin, called aflatoxin B1.
Once ingested by dairy animals in breeding, this is converted in the liver into aflatoxin M1, which is dangerous for humans even at very low concentrations. Classical methods to quantify its presence usually require complex purification and sample preparation processes with the use of chemical solvents, extending analysis times and producing waste, while others do not offer accurate measurements. This invention has developed a spectral detection system which, through the use of a sensor, provides a very precise signal on the concentration of the toxin with rapid times (from 2 to 6 minutes) without producing waste. The tool can therefore be used directly in farms and dairy industries, being portable and compact.
The analyzes may also be carried out by personnel without specific analytical chemistry skills.

  • Biopesticides for the treatment of wine pathogens

    Fungi of the genus Trichoderma produce peptaibols, secondary metabolites that are part of their defence system against other microorganisms. Such compounds are known for their ability to protect plants from parasites by stimulating the plant’s defence mechanisms and because of[...]

  • Characterization of complex sugar mixtures

    To guarantee the quality and authenticity of foods such as honey, fruit juices or nectars, it is important to have detailed information on the type and quantity of sugars they contain. The more common methods used to quantify sugars and[...]

  • Vaccine efficacy prediction in poultry farming

    The method described in this patent can predict the efficacy of vaccines against avian infectious bronchitis virus (IBV), without the use of experimental infections. Currently, the control of IBV in poultry farming is based on the use of attenuated vaccines.[...]
