Particle Size Distribution Measurement of Powdered Young Leaf Blade of Barley

Introduction

Powdered barley grass is often used in health food products. At the distribution stage, it is packaged in dry powdered form, but it is normally mixed with water, milk, or other liquids, to form a suspension for actual consumption. In other words, from the time it is shipped until it is consumed, the barley grass exists in a variety of different states. Particle size distribution is a physical property that is dependent on the dispersion status. Given the same sample, measurement results can differ depending on how the particles are dispersed. This article describes the results obtained from measuring the particle size distribution of the same sample in which the particles were dispersed using three different dispersion methods. Note the difference in particle size distributions, depending on the dispersion conditions. Measurements were obtained using a Shimadzu SALD- 2300 laser diffraction particle size analyzer.
