The analyser offers improved droplet size distribution analysis in food matrices, giving manufacturers additional information about the shelf life and textural properties
Bruker Corporation has launched the minispec droplet size analyser 2.0, the latest addition to its minispec nuclear magnetic resonance (NMR) portfolio. Based on time domain (TD)- NMR technology, the device supports texture and stability analysis in food and cosmetics.
The product features an updated user interface as well as GoScan for minispec, which provides multimodal droplet size distribution characterisation and further improves the results for unimodal distributions where a lognormal shape is assumed.
GoScan for minispec offers data acquisition and processing capabilities and a straightforward evaluation of lognormal and multimodal distribution results. It enables experiment setup, real-time data acquisition, and data analysis. In quality control (QC) mode, pre-defined acquisition parameters are provided for routine experiments, while in the R&D mode the user can optimise acquisition parameters.
The analyser offers improved droplet size distribution analysis in food matrices, giving manufacturers additional information about the shelf life and textural properties. Parameters have been added for emulsions with unimodal distribution where a lognormal distribution is assumed. For the multimodal fitting, a regularisation technique is employed without assuming any shape for the distribution.
Joost Coudron, Laboratory Project Leader at Vandemoortele, added: “The new software of Bruker for the analysis of droplet size distribution makes it possible not only to calculate a log-normal monomodal distribution but also to make a multimodal fitting of the data. At Vandemoortele, we see from time to time, for some of our recipes, that the lognormal assumption for the droplet size distribution is not always the best solution, that the data don’t fit well with a monomodal distribution. With the GoScan software, this is not the case anymore. The software has the ability to recalculate the data for a multimodal distribution. This is a real advantage.”
Omeet Shah, Senior Scientist at Kraft Heinz company, commented: “The Bruker-TD NMR droplet size analyser with GoScan software is an excellent tool for evaluating food emulsions and optimising the processing and formula parameters to achieve consistent emulsion characteristics.”
This latest launch expands the Bruker minispec solutions portfolio, which includes methods for solid fat content (SFC), oil and moisture content, and spin finish analysis.
