Abstract
The present invention relates a method for the detection of at least one mycotoxin contamination from bulk ware, an apparatus for taking a sample of particles from bulk ware as well as a method for taking particles from bulk ware using the apparatus according to the invention and the use of the apparatus according to the invention.
Claims26
A method for the detection of at least one mycotoxin contamination in bulk ware, the method including the steps of:
- (a) taking a sample of particles with a particle size of 0.1 mm to 1.0 mm from bulk ware;
- (b) analysing of the taken sample;
- (c) detecting at least one mycotoxin contamination by determining of the concentration of the mycotoxin contamination, and
- (d) inferring the actual mycotoxin contamination of the bulk ware by correlating the concentration in the sample as determined in step (c) with the concentration of the overall sample of the bulk ware.
An apparatus for taking a representative sample of particles from bulk ware for the detection of a mycotoxin contamination with a separation unit (100) and a suction unit (110), to take the sample by an air stream directed from the separation unit to the suction unit, including a channel (20) with an upstream directed opening (25), in which a sonde (30) is arranged with a sieve (35), a cyclone (40), arranged downstream from channel (20) and vertically to the channel (20) arranged, with a container (45) disposed downwards of the cyclone (40), a channel (50) conducted into the cyclone (40), the channel (50) is directed downstream to a filter (55), a discharging channel (60) downstream of the filter (55), which channel (60) conducts from the filter (55) to the suction unit (110), with a valve (65), and a channel (70), branching of from the channel (60), with a manometer (75) arranged at the end of the channel (70), wherein the suction unit (110) is an air blower, which exerts a velocity of the air stream in the channel (20) of preferably 30 to 70 m/s.
