Unravelling proton NMR spectra of foodstuffs with independent component analysis techniques

thumbnail image: Unravelling proton NMR spectra of foodstuffs with independent component analysis techniques

Overlapping signals in the proton NMR spectra of complex liquids, like foodstuffs and soft drinks, can be processed using a chemometric method, independent component analysis, to extract the spectra of pure components and determine their concentrations.

Farmed salmon can contain pesticide residues, but nothing to worry about

thumbnail image: Farmed salmon can contain pesticide residues but nothing to worry about

Some salmon farmed in Europe contains low levels of pesticide residues, but not large enough to justify the campaign that labels it "the most contaminated foodstuff on the supermarket shelf."

Actually, for me, pesticide residues in farmed fish are a concern.  When I eat farmed salmon (and I’ve tried several times), I get a severe stomach ache and I’m down for the count for at least half a day.  Wild salmon doesn’t bother me at all.  In fact, I quite enjoy it.

I can’t say if farmed salmon makes me ill because of pesticide residues or due to some other factor, but I wouldn’t discount the pesticides.

 

Thermal receipts expose us to bisphenol A: So what?

thumbnail image: Thermal receipts expose us to bisphenol A So what

Paper thermal receipts remain a prominent route of exposure for humans to the estrogenic chemical bisphenol A (BPA), but gloves can protect those who are occupationally exposed.

Latest comment

The increase in BPA in the urine is more of a concern to the microorganisms at the waste treatment plant. BPA that is in the urine is unlikely to disrupt any endocrine function in the receipt handlers.

Inside the brains of jazz musicians

When jazz musicians improvise with each other, they access the same parts of the brain that are used for speech, but the areas associated with semantics, that process the meaning of spoken language, are deactivated.

The contents of 12 elements along with seven elemental ratios have been used to assign more than 900 heroin samples to the Golden Triangle or the Golden Crescentby a procedure which is faster than analysing their organic compounds.
