Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
46 words
A method for the extraction of mycotoxins from mycotoxin contaminated vegetable flours comprising the step of treating said flours or the products obtained with an organic solvent which contains at least a polar group, admixed with an aqueous solution of an electrolyte having an acidic nature.
Claim 2
Independent Claim
46 words
A method for the extraction of mycotoxins from mycotoxin contaminated vegetable flours comprising the step of treating said flours or the products obtained with an organic solvent which contains at least a polar group, admixed with an aqueous solution of an electrolyte having an acidic nature.
Claim 3
Dependent Claim
26 words
