Droplet Size Distribution Analyzer for Food Emulsions

New G-Var Method with Significantly Improved Speed and Lower Measurement Limit of Dispersed Phase Than Former D-Var Method


The droplet size distribution in emulsions of water in oil (and oil in water) influences the taste, smell, appearance, and microbial stability of foods such as margarine, butter, mayonnaise, salad dressing, and soft cheese.

The Bruker minispec provides fast and accurate analysis of droplet size distribution, giving manufacturers important information about the shelf life and palatability of their products. With the new G-Var Method, the Droplet Size Analyzer is now even faster and more cost-efficient than before.

Benefits of the new G-Var Method versus previous D-Var method and other methods:

  • Up to 4 times faster than the previous D-Var method
  • Lower limit of quantifiable droplet phase (now down to 2%)
  • Can measure smaller droplet sizes than before (now: oil droplets 0.5-10µm; water droplets 1-30µm)
  • Highest precision of all methods
  • Lowest total cost of ownership per measurement of all methods

Workflow of minispec G-Var method - Up to 4 times faster in comparison to former D-Var method

Features, Benefits, and Workflow

  • Minimum sample preparation with no sample alteration or dilution
  • Able to measure both, W/O and O/W droplets
  • Similar or better precision compared to other analytical techniques such as microscopy, laser diffraction, and electric sensing
  • NMR measures droplet size and not cluster size
  • Unilever‘s standard method for droplet size distribution measurements in spreads and dressings
  • Very fast method
  • Has the lowest cost-of-ownership per measurement of all methods
