A bittersweet family of plants

Date: Apr 14, 2016

Author: Ryan De Vooght-Johnson

The Gentian family of plants occur worldwide, especially in temperate areas. Despite their notoriously bitter taste, they can be effective at treating digestive problems. A study from China uses a novel combination of approaches for metabolic profiling of these plants, which may help to more accurately differentiate between species.

The magic of maca: a fertility-boosting food

Date: Apr 7, 2016

Author: Ryan De Vooght-Johnson

Maca is hailed as a superfood with fertility enhancing effects, but its active ingredients are poorly understood. This study explored maca samples from China and Peru using liquid chromatography and chemometrics. The researchers were able to separate the samples based on their chemical fingerprint, a method that could be used for labelling and authentication in the future.

Method of detecting mould in air: a new tool for mushroom growers?

Date: Mar 21, 2016

Author: Ryan De Vooght-Johnson

Despite being fungi themselves, mushrooms are susceptible to fungal diseases, which can lead to serious yield losses. Now, researchers have developed a rapid and simple method to identify the disease-causing pathogens in air, which could be the basis for a new quality control system.

Microbiome: In the pipeline

Date: Mar 15, 2016

Author: David Bradley

New metagenomics techniques have revealed the telltale signs of potentially harmful bacteria growing in pipework in a hospital shower facility, according to work published in the journal Applied and Environmental Microbiology. The approach allows strains to be detected that would be invisible to conventional culture-based assays.

Journal Highlight: PLSR modelling of quality changes of lager and malt beer during storage

Date: Mar 14, 2016

Author: spectroscopyNOW

Two partial least squares regression methods have been developed to describe the changes in the properties of lager and malt beer packaged in glass or PET bottles.

Foodomics in action: finding contaminated baby food

Date: Mar 10, 2016

Author: Ryan De Vooght-Johnson

Foodomics – a comprehensive and high throughput approach to analysing food – is emerging as a powerful tool for dietary risk assessment. Scientists from Japan report use of the approach to detect contaminated baby food, identifying pesticides and heavy metals.

Journal Highlight: Prediction of emission spectra of fluorescence materials using principal component analysis

Date: Feb 15, 2016

Author: spectroscopyNOW

A procedure has been developed to approximate the emission spectral data of fluorescent materials of different types from their excitation spectral data using principal component analysis technique.

The spice is right: Spanish saffron samples

Date: Feb 15, 2016

Author: David Bradley

Scientists from the Czech Republic and Spain have used a new cheminformatics "fingerprinting" approach to check data from 44 commercial saffron products to confirm that more than half of products labelled as premium Spanish saffron contained spice from other regions and were thus labelled as such erroneously or fraudulently.

Reading the tea leaves: quality markers for green tea

Date: Feb 12, 2016

Author: Ryan De Vooght-Johnson

Green tea has well-reported health benefits, but the compounds responsible for these effects are still not fully understood. This study used a combination of chromatography and chemometrics to identify the two most important compounds in Brazilian green tea samples, which could be used as quality markers.

Journal Highlight: Detection of Alzheimer's disease signature in MR images seven years before conversion to dementia: Toward an early individual prognosis

Date: Jan 18, 2016

Author: spectroscopyNOW

The performance of a new MR-based hippocampal grading score based on a pattern recognition strategy has been used to assess incident dementia in cognitively intact patients.
