Particle size analysis is important in many industries. Knowledge of particle size is important in the food industry because it affects the production and handling of ingredients and the formulation, processing, and quality control of food and beverage products. Particle size affects reactivity, solubility, and flowability of ingredients and the texture, mouthfeel, and processing of products.
Particle size analysis has been applied to a wide variety of ingredients and products, including coffee, sugar, salt, flour, chocolate, milk powder, spices, and flavors. Analytical techniques for measuring particle size range from traditional sieving and sedimentation to use of modern automated imaging and laser-based instruments.
