Pesky Pesto Peculiarities and GCxGC Analysis

February 11, 2022

Pesto can trace its roots back to ancient times, though it really only started taking off in North America in the 1980s and 90s. Though the primary base is consistent, with pine nuts, basil, and olive oil, individual recipes vary. As canned and bottled pesto became more accessible, individual manufacturers developed their own unique flavor profiles. While these recipes are usually trade secrets, the power of GCxGC TOFMS can tease apart some of the differences.

Towards an Even Better Tasting Veggie Burger with GCxGC-MS

August 27, 2021

Sustainability is on everybody’s mind these days. Companies want to create products that are better for the environment and consume fewer resources. Unilever is no exception. This forward-thinking flavor company has recently been pushing to develop new and delicious plant-based protein substitutes that are more sustainable than meat-based protein but no less healthy (or, preferably, even more healthy!). However, as Unilever scientists Hans-Gerd Janssen and Ed Rosing explain, nature made a pretty delicious protein in the form of meat, with a very distinct flavor and mouth-feel. Creating a substitute isn’t easy.

ChromaTOF® Tile for GCxGC Analyses

January 29, 2021

LECO has released a revolutionary new data analysis software for GCxGC data: ChromaTOF Tile. This software provides an industry-first data comparison tool that identifies statistically significant differences between classes of samples, reducing days-to- weeks of work down to hours, or even minutes. Based on Dr. Robert Synovec’s tile-based Fisher ratio analysis, ChromaTOF Tile partitions the data into a set of regions (tiles) and compares regionalized data. This allows it to disregard normal variances of alignment shifts to focus on where the actual differences are, so users can stop looking at their data and start actually using it.
