Microbial Contamination in Leafy Greens: Open Fields vs Greenhouse Cultivation


via Accelerating Science » Amanda Maxwell http://ift.tt/1KClwFi

With the current attention on risk factors for foodborne illness, farms are quite rightly under scrutiny for implementing good agricultural practices (GAPs) with regard to minimizing or eradicating contamination during crop production. Holvoet et al. (2014) examined risk factors for microbial contamination in lettuce crops under open field or greenhouse growing systems1. Since fresh leafy Read the rest of this article

Enabling Proteomics Data Exchange with mzTab


via Accelerating Science » Amanda Maxwell http://ift.tt/1SZ4DpV

Proteomics researchers benefit—or suffer, depending on the point of view—from a plethora of file formats with which to store data. Some may be used because of personal preference, while others because of instrument manufacturer specifications. Although all formats store mass spectrometry data, their incompatibility may not allow exchange or comparison between studies. Furthermore, the situation Read the rest of this article

A Proteomic Ruler That Measures Up


via Accelerating Science » Amanda Maxwell http://ift.tt/1SOxIV1

According to Wiƛniewski et al. (2014), using the mass spectrometry (MS) signal generated by histones is a reliable and easily implemented first step in quantitating proteins.1  Furthermore, using the “proteomic ruler” tool developed by the authors, researchers can cut out several steps that potentially introduce error in MS-based proteomic quantitative analysis. Since its introduction into Read the rest of this article

Measuring Primary Aromatic Amine Migration into Foods by Targeted LC-HRMS


via Accelerating Science » Amanda Maxwell http://ift.tt/1PTODAa

Sanchis et al. (2015) present a sensitive and efficient method for measuring primary aromatic amine (PAA) contamination in foodstuffs using liquid chromatography coupled with high resolution mass spectrometry (LC-HRMS)1. The method the researchers propose benefits food safety monitoring by providing both targeted measurement of PAAs but also post-target screening for other common migratory contaminants such Read the rest of this article

Plant Antimicrobials and the Food Industry: Part 3 – Phytochemicals


via Accelerating Science » Amanda Maxwell http://ift.tt/1QE17PG

Phytochemicals are components within a plant that often impart taste or flavor. Classified as non-nutritive, these factors can also be antimicrobial—a property that has been exploited throughout history. Many cultures use herbs and spices in both cooking and medicine, as much for the pleasant sensations they impart as for their antimicrobial actions against foodborne pathogens, Read the rest of this article
