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 oligosaccharides are based on separation techniques such as HPLC and GC, but they do not yield precise results on different instruments.
The present invention proposes a method for the identification and quantification of sugars present in complex foods with the CSSF TOCSY NMR, a technique capable of simultaneously identifying and quantifying the types of sugars present in honey, fruit juices, milk or wine with greater precision.
In particular, the method is applied to food matrices as is without the need for expensive chemical pretreatments before instrumental analysis.
In this context, the same method also lends itself to the analysis of biofluids such as urine, serum, saliva and breast milk, to trace the presence of metabolites that may indicate any disease conditions.

  • CO2 SUP – Food preservation with supercritical CO2

    This invention uses supercritical carbon dioxide to pasteurize food, at temperature and pressure conditions that do not alter its structure or flavour. The process allows for longer product shelf life since it reduces the presence of bacteria in fresh food[...]

  • RAPID-AFM1 – Rapid detection of Aflatoxin M1 in milk

    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[...]

  • 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.[...]
