Evaluation of Particle Size in Chocolate—Evaluation of Particle Size Distribution and Coarse Particles that Affect Texture—

User Benefits

- The solid particle size distribution in chocolate can be easily measured using the SALD-2300. - The iSpect DIA-10 enables not only the measurement of particle size distribution but also, the number concentration of particles in a specified particle size range.

Introduction

Particle size distribution is one of the physical properties that describe the characteristics of materials and products containing particulate matter. In some cases, the difference in characteristics can be described simply by the average particle size. In other cases, the amount of particles above a certain size is important. The values to be noted vary depending on the type of material, product, and its intended use. Here, chocolate is taken as an example of a product where particle size control is important. An example is presented of measuring the particle size distribution and the quantity of particles within a specific size range to assess the texture of chocolate. When performing chocolate quality control, the particle size distribution is generally evaluated using a laser diffraction-type particle size distribution analyzer. In this article, in addition to using the SALD-2300 Laser Diffraction Particle Size Analyzer, the iSpect DIA-10 Dynamic Particle Image Analysis System is also employed to show the possibility of a slightly different evaluation approach to investigating the relationship between particle size/concentration and texture.
