The Assessment of Dissolution Process of Powdered Sports Drink by Continuous Measurement Function of SALD Series

Introduction

Various sports drinks are available on the market today. These sports drinks can be broadly categorized into those sold in liquid form, such as in plastic bottles, and those in powder form to be used after dissolving them. Of these two, powder form is easy to carry, and the concentration can be easily adjusted for the purpose of sugar level control. Such powdered sports drinks must also dissolve quickly even at room temperature. In this research, taking a powdered sports drink as a sample, we measured the particle size distribution in the dry state, and the change in particle size distribution as the sample dissolves after being added to water, using the SALD series laser diffraction particle size analyzer. The SALD series is effective in the analysis of dissolution that occurs within a short period of time since continuous measurement at as short as 1 sec intervals is possible with the simple optical system which consists of a single light source. The size of residual particles that affect the texture and smoothness of the drink can also be measured. This information can be utilized in the development and quality control of other powder form foods and pharmaceuticals.
